It makes screenshots on its own and saves them in the gallery. I delete them but it makes new screenshots. I stopped an running app that says "screen capture" but it does it again. I can't delete it, it's not an installed app. What can I do do permanently stop this nonsense? | I believe its being caused by a certain combination of buttons at the bottom of the screen. I haven't found a workaround, but here is something you can do to, at least not to store images (its not much, but something). It creates a directory "ScreenCaptures" to store images in; if you delete it, it will be simply recreated. So, instead, in the same directory, create a file with that name. Every time a screen is captured, it will complain that it cannot be stored, so at least you won't have to worry about deleting those images. | Galaxy mini S5570 automatically creates screenshots | android |
I created this <code> Data.osm </code> file: <code> <?xml version='1.0' encoding='UTF-8'?> <osm version='0.5' generator='GPSBabel-1.4.0'> <node id='-1' visible='true' lat='41.890121' lon='12.492265'> <tag k='name' v='place01'/> <tag k='note' v='place01'/> <tag k='tourism' v='museum'/> </node> </osm> </code> Then I converted it to <code> Data.obf </code> using OsmAndMapCreator. How to have OsmAnd show this POI on the maps? | 1) Copy the <code> .obf </code> file to your OsmAnd folder, for instance <code> /sdcard/osmand </code> . 2) In OsmAnd, enable the "POI > Any" layer. 3) Sometimes it does not work immediately, in such case restart your phone (there might be faster methods but at least restarting works) | How to import a .obf POI file in OsmAnd | android |
Do I need to worry about malicious apps on Google Play, or can I trust everything I install, so long as I install it from Google Play? And if I need to worry, what red flags should I look for - number of downloads, ratings, how old the app is, what permissions it requires? On a practical level, would you say that it is as safe as Apple's App Store? | We don't compare apples with peaches. But it's always a good idea to be careful what you install. True, Google Play is to be considered one of the safest sources for Android apps. Still, some malware sneaks in every now and then. So you should use some common sense before hitting the "Install" button. Things to look at include (but might not be restricted to): What permissions are required? Though not always easy to decide, there are some things which can count as indicators – e.g. taking a simple calculator app, it certainly doesn't need access to your contacts, calendars, system settings, etc. How is it rated? I'm not talking about "naked numbers", but check the comments. They might give you useful hints on whether it's safe to install. Also, an app installed several thousands of times with no traces of maliciousness in the comments should be considerably safer than an app with almost no installs and no comments. Should it be a very popular app, but only has few installs? That's in most cases a clear indicator for malware, hiding behind a popular name. Better keep your hands off those. Aside of that: In case you're still unsure, pick a good forum and ask. Another good idea is to check other apps from the same developer (just follow the link on his name), and use above criteria on them. | Can there be malicious apps on Google Play? | android |
On my Nexus 4, when I get a notification the LED blinks. However it is very slow so you can't notice it with a quick glance at the phone. Is there a way to make the LED blink faster? | There is no way to control the blink speed in the OS itself. However, Light Flow provides a plethora of options for colour, flash rate, etc. There are probably other equivalent apps too. | Is there a way to control the blink speed of the notification LED on Nexus 4? | android |
I'm trying to copy a string of text from a nfc tag, but the only option I've been able to find is displaying the text with no ability to copy it (its a complex string with letters and numbers). Best case scenario would be to insert the string where the cursor is at the moment the tag is pressed, but I'm okay with somehow getting the string to the clipboard to paste. If this isn't the right place to ask this question, if you could tell me where I could find the answer, I'd be very grateful. | NXP's NFC TagInfo app can copy the text from a text record on a scanned NFC tag to the clipboard.

I'm trying to get my phone (JiaYu G3T) working under adb on Windows 8 x64 (worked fine on Windows 7 x64 before reinstalling my OS). Driver Android Composite ADB Interface, version 8.0.0.0, works fine. My adb won't list any devices ( <code> adb.exe devices </code> ). I tried: installed Google USB driver enabled debugging mode in phone added my device's hardware IDs to the Google USB driver inf file and installed installed Moborobo (phone works fine in there but adb still won't find the device) tried switch Settings > Storage > Menu > USB Computer connection to "Camera (PTP)" tried two different version of adb (1.0.31 and 1.0.26) Those were some of the advices I found so far. | Finally it works, I'm using the Google USB driver.

OsmAnd is a map/navigation app. On top of the map, I would like to display "Points of Interest" (POI), for instance my city's best restaurants. I already have a CSV file containing for each POI: name, latitude, longitude. How to make OsmAnd use this data? The wiki page How To Use Your Own POI Database suggests it is possible but does not give any specific instructions. By reading stackexchange-url ("this unanswered question"), I get a feeling that somehow converting my CSV to ODB might be part of the solution. I would like the database to be easily downloadable/usable by anyone. For the curious: Actually, my long-term goal is to create a database of all POIs in the Wikivoyage travel guide (maybe split by country if too big). | Just a guess, but worth trying: I did the same with Locus Maps . I created a KML, which imported fine, and could be used as layer there ( Locus even supports KMZ containing images and more, so you could use that for a "self-made travel guide"). The article Using KML Files on the same site suggests at least the KML part should work with OsmAnd as well, so I considered placing this as answer (instead of making it a comment). This article even explicitly mentions POIs – which probably is the reason your linked article contained that few details: You may use any format containing your POIs, if you are able to convert it to osm format. and All points inside the kml file are converted into osm points, assigning them some properties like tourism category and museum type. Note the categories mentioned here match those on your linked article. | How to create a POI database for OsmAnd? | android |
Some time ago, both Chrome and Chrome Beta started going full-screen. That is, I no longer see my status bar. This is a deal breaker for me, as I can no longer see what time it is or if I have notifications. I have browsed chrome://flags and didn't see anything related to this. Is it possible to disable this full-screen mode?

Then I couldn't switch it off. I deleted all data in Chrome, and the problem was fixed. There was no need to uninstall the app, just cleaned the data using the Android built-in Application Manager. It seems some website included code that caused this, and the Chrome for Android simply does not have the settings to revert this. Hope this helps. | How do I disable full-screen mode in Chrome for Android? | android |
I have rooted my phone recently and just installed ROM Toolbox which has several Governors available. It is using OnDemand by default, but I switched to Interactive. I just need to be as close to default settings in order to maintain stability. Btw, when I am using a third party app to change CPU Freqs, ROM Toolbox in this case, It seems to be a bit laggy. Is this normal? | I don't know the default governor for the Galaxy Mega. However, there's an easy way to determine your current governor. Rebooting the phone (Unless you ticked the option in ROM Manager and/or other apps to persist governor selections through reboot) will reset it back to its default setting. You can find your current governor by running the following command in an adb shell or terminal emulator: <code> cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor </code> Chances are your default governor is indeed ondemand. It is commonly used as the default governor on many Android devices, and seems like one that Samsung would like to use. | What is the default Kernel Governor in Stock Samsung Galaxy Mega Android ROM? | android |

I wonder what is the purposes of each of these extra folders that android creates on a sd card. Edit: .android_secure .data .estrongs .showme _nero_sync Alarms Albums Android DCIM download LOST.DIR media Movies Music My Documents Notifications OTA-Updater Pictures Podcasts ppy_cross Ringtones | Each app on your phone with the WRITE_EXTERNAL_STORAGE permission may create files or folders there. Most of these folders have once been created by one of these apps and many of them may be deleted with a few exceptions (e.g. Android, .data, .android_secure, these contain important system or app data like a game's downloaded content). Alas, it's impossible to tell exactly which folder belongs to which app. .android_secure: apps installed and then moved to sdcard Android: app data/cache data: app data .estrongs: ES file manager LOST.DIR: sort of trash folder (collects recovered files after phone crashes) DCIM: phone gallery's photos and previews OTA-update: Over The Air update service ppy_cross: an unknown third-party app's data. info I think you know what's in the others :) Generally, note that uninstalling an app doesn't clean up the stuff it has created there.

I have a Samsung Galaxy Nexus and a Samsung Galaxy Mini2 . In mid-August I lost my GNex battery charger; then I started charging the GNex with the Mini2 battery charger. Their specifications are: <code> GNex : Volt 5,0 Ampère 1.0 Mini : Volt 5,0 Ampère 0.7 </code> Since the second battery charger has a lower Ampèrage, it should charge the phone exactly like the original one, but taking more time; In mid-September, the GNex started doing strange things: the charge was degrading faster than before (I'm used to charge it every two days, while from mid-september I charged it every day), and THE PHONE BECAME SLOW. I mean SLOW . Even if restarted and powered on from few minutes, the Application button took about 4-5 seconds. Before it was instant and smooth, about 0.2 seconds. In mid-October I found my original battery charger, and started using it again. After a couple of charges... the phone has returned to be superfast. Talking with a friend (physicist), it said it must be a software (or hardware) thing. A wanted behavior set up in order to slow the phone down when not using the original battery charger. I said that it sounded a bit like conspiracy stuff, then he argued that it is more likely than the electrons remembering which battery charger transferred them and based on that deciding to slower the phone or not :) Another friend (electrical engineering technician) said it is common practice (and brought examples from Laptop manufacturers's world); Is this a known issue ? If yes, is this Google or Samsung's fault ? (Why on earth should they do something that stupid ? But this is rhetorical... ) Note: the "case study" is perfectly reproducible, the only requirement is to have two different battery chargers (with a different ampèrage) and a GNEx, but probably it is done on other phones too. | No, they don't behave differently if you don't use the original charger. I have a Samsung phone that has never even seen its original charger, along with some Nexus devices in similar conditions, and they don't suffer from slowdown or anything like this. More likely, your phone is running low on internal storage, or you've recently installed an app that hogs the phone's CPU or RAM. There are lots of questions on the site about troubleshooting and debugging that kind of slowdown. Start by looking at the list of running apps in the phone's settings, browse those questions, and maybe ask a new one if you find something more specific. | Android software runs differently based on different battery chargers? | android |
I have downloaded a dictionary application for my native language and English translation and it can work offline. But i need it to be seen at the "select an action for text" menu when i select a piece of text on a browser, or an e book reader, or an offline browser. Is it the business of developer of the dictionary app? If not how can i add an app to "select an action for text" menu? Thanks. | Short answer You yourself cannot. But you can ask the developer to implement that. TL;DR Explanation in easy terms: an app itself must "register for this service", which must be done in code. The "Share picker" is not handled by apps directly – it's rather the system taking care for that. So it must be made known to the system if an app has something to contribute (or can accept from) here, and if so, for what actions/content types. For example, an URL (link) basically is "normal text" (consisting of characters), so it could be copy/pasted to other "text processing apps" (notepads, word processors, etc.); but it could also be passed to browsers or other link-sharing apps in a specific way. A video makes no sense to be copied into a text-based app, so when "sharing" it you wouldn't like a notepad-type app to be in the share menu (which otherwise would be really cluttered pretty soon). So an app must "tell" the system what type of "sharing content" it can accept, and it must provide a "standardized interface" for this which the system (or rather its "share" component) then can address. Additional hints As your question was for a dictionary-type app: Several other apps support those directly. So e.g. ColorDict (my personal favorite currently) is an online/offline dictionary app directly supported by e.g. Moon+ Reader (my favorite app for reading eBooks – ePub, Mobi, PDF, and more supported). Looking up a term even makes ColorDict blending in seemlessly. So apart from the "standard sharing option" of the system, there are also other ways to achieve things. But again, it's up to the developer to implement this. | Can i customize "select an action for text" menu? | android |
First, I hope I choose the right stackexchange for that question. Android 4.3 introduces a "Hardware-backed" Credential Storage. If I go to Settings-> Security under the "Credentials-Storage" Header there is a (non-clickable) option "Storage-Type" which is set to "only Software". How to set it to "Hardware-Backed"? I already removed/reseted the credentials storage and tried it with different LockScreen-Options (Pin, Password, Pattern), but I can't get that option to change to "Hardware-Backed". Isn't the Galaxy Nexus capable of enabling it? | The "Hardware Backed Credential Storage" aka "Android Key Store" is only hardware backed when the hardware on the device has the necessary hardware components in it. When there isn't the necessary hardware available it falls back to software storage. Android also now supports hardware-backed storage for your KeyChain credentials, providing more security by making the keys unavailable for extraction. That is, once keys are in a hardware-backed key store (Secure Element, TPM, or TrustZone), they can be used for cryptographic operations but the private key material cannot be exported. Even the OS kernel cannot access this key material. While not all Android-powered devices support storage on hardware , you can check at runtime if hardware-backed storage is available From Android 4.3 APIs - hardware credential storage. My emphasis. Finally, there is an API and even a system settings field that lets you check whether the credential store is hardware-backed (Nexus 4, Nexus 7) or software only (Galaxy Nexus) From Credential storage enhancements in Android 4.3 This a new feature and so it's likely that only newer, higher end devices have the hardware in them. According to that, the Galaxy Nexus doesn't have the necessary hardware. The Nexus 4 does have full hardware support for this; As you may now (sic), the Nexus 4 is based on Qualcomm's Snapdragon S4 Pro APQ8064 SoC. Like most recent ARM SoC's it is TrustZone-enabled and Qualcomm implement their Secure Execution Environment (QSEE) on top of it. From Credential storage enhancements in Android 4.3 The ARM TrustZone technology is analogous to the TPM hardware used on Intel x86 PC compatible hardware to provide a hardware secure credential storage area. And just like TPM when it was first introduced is taking a while to trickle into all new phones. So, in the case of the Nexus 4, the 'hardware' is simply the ARM SoC. Are other implementations possible? Theoretically, a hardware-backed keymaster implementation does not need to be based on TrustZone. Any dedicated device that can generate and store keys securely can be used, the usual suspects being embedded secure elements (SE) and TPMs. However, there are no mainstream Android devices with dedicated TPMs and recent flagship devices have began shipping without embedded SEs From Credential storage enhancements in Android 4.3 So, no, the Galaxy Nexus is not capable of enabling hardware backed credential storage, because it doesn't have the necessary hardware in it. | Hardware backed Credentials Storage on Galaxy Nexus | android |
I'm looking forward to reinstall Android on my Samsung Galaxy Tab 2. Are there compiled images for this device? Do I have to build it myself? If so, do I need propietary drivers from Samsung? All the tutorials I found around require Windows (for Odin software) and installing mods and stuff like that, that sounds very hacky and dirty to me. | From a GNU/Linux-based OS, you can use Heimdall , an open-source alternative to Odin which is proported to match Odin feature-for-feature while also being more reliable. Otherwise, you can follow any of the many tutorials for installing a new Android ROM. I'll provide a bit more information to help you start your journey: If you want a custom ROM like CyanogenMod or any of the dozens which are available in precompiled packages for specific devices, then you'll need to use Heimdall to flash a custom Recovery image ( TWRP or ClockWorkMod Recovery ). The zipped ROM images are flashable through these recovery modes. If you want stock, Samsung Android/Touchwiz then you can use Heimdall to flash over the entire Android image from Samsung. (Google around to find the one for your model) If you want to compile Android yourself , you'll likely want a custom Recovery image ( TWRP or ClockWorkMod Recovery ) and you can download the Android source code or if you want to modify existing custom ROMs, you can download their respective source and compile it yourself. You'd need to hunt down some in-depth Android compiling tutorials in order to do this, as it's not a simple process . Note: Before flashing anything to your device, make sure that you match the model numbers! | Install Android to Samsung Galaxy Tab 2 with GNU/Linux | android |
I am using the market app Startup Manager on Android, but I am a little bit concerned in the way that it operates. Is it effectively runnning every time as a daemon and thusly keeping the apps from not starting or does it simply change the bootable flag in the apps, without running in the background? | It all very much depends on the "startup manager" used, and whether your device is rooted. As stackexchange-url ("dotVezz answer") assumes, there are some just de-activating the corresponding "listeners" (apps can be notified on events, and thus get started when they appear – the most famous event being <code> boot_completed </code> ; but there are many more, like network changed, SDCard mounted, battery low... If you are interested in details, see e.g. stackexchange-url ("What's the difference between a service and a broadcast receiver?")). However, doing that requires "root powers". Thus "startup managers" working without "root powers" basically do nothing other than task mangers: killing the app once it started on a given event. They also in most cases stick to the <code> boot_completed </code> event, and don't care about others. Then there are those managers supporting both modi. Best one most likely is AutoRun Manager , my favorite I used for quite a while. Now your question is specifically about Startup Manager . As you can see in its app description, and like I've written above, this app just cares for the <code> boot_completed </code> event: it does disable/enable startup items from system boot . Its permissions do not include <code> SUPERUSER </code> (aka root), so it cannot modify receivers/listeners. So it most likely just "kills" the apps when they start. Prove on that you again can find in the app's description: Note: For android 2.2 and higher OS non-rooted devices, some processes will restart themselves right after being disabled. They wouldn't do so if they were really disabled . But many apps do so when being killed . AutoRun Manager , which I've mentioned before, supports both modi: If used in "Basic Mode" (which does not require root), it kills configured apps on start. In "Advanced Mode" (requires root) it "silences" their listeners, so they never receive the event broadcast and thus do not automatically start. | How does Startup Manager block startup apps? | android |
Some apps in Application Manager are completely greyd out and cannot be disabled. Is there any way to override this? | As your device is rooted, you might want to check some tools which help you on this task. Examples include Titanium Backup , which (next to Backup almost everything) can freeze apps (which is the same as "disabling" them), and App Quarantine , which is even dedicated to this job. The two are just examples, there are more "tool boxes" out there capable of the job in question. Another way (not requiring extra apps) is utilizing ADB for this: <code> adb shell pm disable <package_name> </code> could be used to disable an app (see also stackexchange-url ("this answer")). | Disable Android Apps - Application Manager | android |

I was re-arranging my icons when I accidentally dropped an icon "behind" the google search bar up top. The icon appears on every screen when I swipe left or right, but disappears when I view all apps. How do I remove this icon? (see the mis aligned YouTube icon at the top) Screenshot (click image for larger variant) | Note that my other answer is more of a workaround (but also something recommended by many even without problems) that is almost guranteed to fix the problem. This is a direct fix which will most likely work, but I can't say that with absolute certainty as I can't recreate the situation myself. After some googling, I've noticed that your icon (as you point out already) is off-center and missing its text label. Rather than the icon itself being stuck, it looks like what you're seeing is a stuck graphical artifact. This has happened to a few other users on other forums , and rebooting the device seems to be a fix for them.

I currently have a <code> Samsung Galaxy SII (S2)(I9100) </code> that got dropped in water. I took the phone apart (removed the screws on the back and properly took the back off) and left it to dry in a warm place overnight. The phone works absolutely fine as you'd expect it to, but it now has this weird issue where the <code> screen won't turn off </code> at all, whenever I press the power button to turn the screen off, it comes straight back on again. If I let it go to sleep with it's own "timout" it just comes back on straight away also. It has been <code> factory reset </code> and still does it. It has <code> stock Android that came with the device </code> , <code> never rooted </code> or had <code> custom ROMS </code> installed. Here's a video of the problem actually happening: http://www.youtube.com/watch?v=c4UViRT64Ss I assume it has to be a hardware issue from the water damage, but has anyone experienced this? Is it likely I'd be able to change any of the parts inside to try and fix it? | The water evaporating has left now undissolved mineral ions on your phone (ions conduct electricity).Now electricity doesn't go as designed.Also heat cycles will possibly change chemical and physical structure of your hardware.The more you use it the more likely something will get worse Instead of drying to get rid of water and leave the ions on your phone you should have hoovered the water being cautious not to discharge static electricity to the phone (even though theoretically almost everyone should have damaged their hardware with static many times in their lives it somehow never happens) Now maybe you should clean it properly (isopropyl alcohol should work the purer the better at least 99%) The better way to clean it is with bathing it in the alcohol and use ultrasound at the same time which some more professional phonerepairers do with special machines.(You can find some good replacements of the machines for about 50usd) It most often works without ultrasounding but the ultrasound method is much better and fixes the performance of water damaged phone more. | Phone dropped in water - Now screen won't turn off (Samsung Galaxy S2 (SII))? | android |
I'be been working on some Chinese (bit crappy) device, with own system, that had one wonderful (at least for me) feature. When constantly powered-up (plugged to power adapter) it could work without the battery inside. Is there any Android-based phone or device that does the same? Or the only option here is to keep battery inside, keep it powered up all the time (I have some reasons for that) and replace battery quite often, since it will be charging and discharging it the same time (will it), thus lowering its life-span. | Don't you worry. LiIo batteries are not that concerned about that. What really lowers their life span are "complete discharges", not frequent "trickle-charging". It's even recommended to charge them as soon/often as possible (and practicable, of course).

Whenever I run Root Debug FS for my Samsung Galaxy Stellar (4.1.2 jb, Model # SCH-I200, baseband I200VRBME1), I get this error: ADB.exe is an application in the same folder as the batch file, but it says it won't run. When I run ADB.exe it just flashes the commnad line and goes away after writing out a ton of text (it dissapears too quickly for me to read it) | As it turned out: with <code> adb.exe </code> not being in the <code> %PATH% </code> (or <code> $PATH </code> for Linux/Mac users), the batch file was not able to find it. So there are 3 solutions to it: fixing the batch file to look in the very same directory fixing the <code> %PATH% </code> / <code> $PATH </code> to include the directory changing into the directory the batch (and ADB) files are located in, and running it from there For a one-time run, #3 is the easiest approach: open a command shell (on Windows via the start menu, open a <code> cmd </code> – on Linux via ALT + F2 and entering e.g. <code> xterm </code> ) change to the directory (using the <code> cd </code> command with the directory as argument; on Windows, you might need to switch to the correct drive letter before) run the batch/shell script from there If you need that script more often, it might be worth trying one of the other two approaches. Not being a Windows user, I don't know where exactly to add the <code> PATH </code> information there (AFAIR it was in "Environment variables" somewhere in the settings of the control center); on Linux you can just do so in your <code> $HOME/.profile </code> or <code> $HOME/.bashrc </code> , adding a line like <code> export PATH=$PATH:/where/is/adb </code> (of course using the correct path instead of <code> /where/is/adb </code> ). Fixing the script/batch is a little beyond the scope of our site :) | Root Debug FS doesn't work | android |
I am looking for a way which will allow me to make HTTP requests to my web server when there is an incoming call (or outgoing/missed called etc if possible). This is so that I can log the information (CallerID primarily) and perform actions in my own system based on the number that is calling or being called on the handset. I need the request to be made while the call is either ringing or in progress - i.e. what is happening now, not what happened previously. An example use for this is so that I can present information about a caller on another computer which is connected to my system when someone calls. An alternative to HTTP would be fine, such as SMTP or some other notification/external communication. | You might want to take a look at Tasker , the mighty automation solution on Android. I have not setup something as you request, but it's definitly possible, and basically should work like this: Condition: Event → Phone Ringing Task: either HTTP GET or HTTP POST to your server's URL.

I got excited about the prospect of writing code for a watch and ordered a Samsung Galaxy Gear. Currently the device does nothing unless paired with a Samsung phone running the proper version of the official software.

So my android 4.3 personal dictionary abbreviation/expansions work fine in some text inputs such as memo pad or text messaging, but it seems if the input is specialized such that it knows to expect an email or a phone number, the expansions are not available. Is there a way to make these always available when the keyboard is active without exception? If not, how can I otherwise avoid typing out my long email address when setting up settings, filling out web forms, etc? | As you've noticed, the app you're typing into can tell a "hint" to the keyboard app (or input method ) to let it know what kind of text to expect, such as an email address. It's then up to the keyboard app to decide how to interpret that. For example, it can look in your contacts for email addresses. You haven't said which keyboard app you're using, but from what you've described it seems that this app chooses to ignore expansions when it receives this hint. Since it's up to the keyboard app what to do, you might like to install and try out a different keyboard app. I don't use expansions/abbreviations myself, so I can't recommend one, but there must be one out there that lets you use them for email addresses, phone numbers, etc. as well as normal text. Do bear in mind that a keyboard app can record all the text you type, so be extra careful to only install apps from reputable sources and developers. | Why are personal dictionary entries unavailable in some input fields? | android |
I'm using a Android 4.2.2 ROM (sun7i_android_sugar-cubieboard2-8192cu.img) for Cubieboard. I need more room in system partition for install more goodies!

My Samsung Galaxy Y (GT-S5360L) can run a wifi tethering network at 32 dBm, according to iwconfig. This is almost 2 watts. Is this reading accurate, (my battery is 1200mAh, 5v, or 6 watt hours, so it seems sort of fishy, but it does drain my battery really fast when I run it), and if it is, (assuming nothing blocking the signal) what is the range of the network in meters? | 32 dBm equates to 1584.89mW according to this calculator: http://www.radiolabs.com/stations/wifi_calc.html Assuming a 12 DBi Antenna Gain from the comments above, that gives us 44 dB of antenna power.

I just uninstalled and reinstalled Hangouts to get the updated version. (Even though the market showed the new version, it didn't have "Update" yet).

I am currently a loyal Verizon customer, and have been pretty much forever. My current phone is a Galaxy Nexus, and my previous phone was a Droid, and the carrier has been fairly hands-off with these "stock" Android models. I'm currently out of contract, so I have the ability to freely/easily switch carriers if need be. I really like Verizon's coverage, but might be willing to jump ship for various reasons. (Carrier decision is really a separate question) I'm currently interested in the Galaxy Note 3. However, I'm concerned about what modifications Verizon may have made to their version of this model. The main reason for my concern is this list of differences about the previous model, the Note 2: http://engadget.com/2012/12/07/dnp-samsung-galaxy-note-ii-verizon-review/ What especially concerns me is things that were removed and hardware differences, such as the Verizon model of the Note 2 missing the wireless charging contacts, but on principle I am also concerned about firmware and software differences (other than the necessary CDMA chip, of course, and I can live with additional Verizon branding and bloatware). I have asked this question in a variety of forums, including asking Verizon and Samsung directly, but haven't gotten a straight answer. I'm hoping that "no news is good news" and I would really like to dive in and take this model. But if there are any differences, I'd like to know them. I just want to make sure I am getting the features as-advertised by Samsung. Thanks! | Self-answering update from OP: I have now owned a Verizon Galaxy Note 3 for about 6 months and there are no significant differences between this and another carrier's model.

On some phones, when an external USB drive is connected to the phone, there is sort of an autoplay function where it automatically brings up the "My Files" screen. Is there a way to suppress this? This occurs on my Note 2 with Android version 4.1.2, but not on my Note 1 with version 4.0.4. Just to be clear, I want the drive to automatically mount in the background as usual, but just not bring up the "My Files" screen. I have an app that expects a USB drive to be plugged in and searches for specific file types and this behavior is annoying because it takes the screen away from my app. | I was hoping to be able to programmatically suppress the default "My Files" system app from starting when a USB storage device is plugged in, but it looks like it is not possible. However, I did find a workaround. First I installed a new file manager/explorer from the market (I used ES File Explorer). Then I went to Android Settings -> Applications and then selected the My Files app from the list and disabled it.

I have a similar problem as the one stackexchange-url ("described in this question"), but that question doesn't solve my problem. Summarized here: I recently installed CyanogenMod 10 on my Galaxy Nexus. I enabled encryption. The first time I rebooted the phone, I was able to get past the lock screen with no trouble. I tried to change the screen lock PIN, but the settings app wouldn't accept my PIN. Later, the screen locked due to the timeout being reached, and I wasn't able to unlock it. My password kept being rejected, and the "Forgot password" button that I read should come up never appeared. I rebooted my phone, and though I can easily decrypt it, I can't unlock it. stackexchange-url ("This answer") suggested going through <code> adb </code> to fiddle with an SQLite database. However, I can't seem to access <code> /data </code> on my phone. I get the following error when I try to do an <code> ls </code> : <code> opendir failed, Permission denied </code> I tried to use <code> su </code> , but again, I got a <code> Permission denied </code> error. The phone is most definitely rooted, as I regularly use several root-only apps. I really don't want to have to wipe the phone. Is there any other way to unlock this phone? Edit After posting this question, I came across stackexchange-url ("this answer"). I was able to get my phone unlocked by exploiting the phone hole mentioned (involving calling the phone and mashing the keys repeatedly--though instead of hitting the non-existent home key I swiped up Google Now). I deleted the password using the SQL mentioned in the answer I cited earlier. However, upon rebooting the phone, I'm back in an non-unlockable state. In other words, I can exploit a hole to unlock my phone, but I can't reset the PIN, and I have to make sure to turn my screen on before 30 minutes elapses and avoid rebooting, or I'm toast. | I got it fixed. Here are the steps I took: Use the stackexchange-url ("exploit here entitled "Phone: Use a hole to disable your lock""). For me, it didn't work exactly as documented, though. I had to mash the password keys for a long time (calling my phone was unnecessary), then swipe up Google Now, mash the password a few more times, and hit <code> Enter </code> . With that, Google Now pops up and the phone is unlocked. I didn't test to find out how much of this is necessary and how much isn't. Fire up a terminal app on the phone. I can't get root access from <code> adb </code> . Type <code> su </code> to become root. It should go without saying that this method will not work unless the phone has been rooted. Enter the following commands to clear the password (stackexchange-url ("source")). Each line represents a command to type, one at a time. <code> sqlite3 /data/data/com.android.providers.settings/databases/settings.db delete from secure where name='lockscreen.password_type'; delete from secure where name='lockscreen.password_salt'; .exit </code> Tip: These commands will be easier to type if you use Hacker's Keyboard and type with the phone in landscape orientation. Reboot the phone. The screen will still be locked and non-unlockable. So, repeat step 1 to unlock it. Go to the security screen and hit <code> Screen lock </code> . You will be asked to confirm your PIN. The new password is null. That means that instead of entering a password, just hit <code> Next </code> with a blank password. Now, you're in, so go ahead and change your PIN to whatever you want. | Clear or reset my lock screen password/PIN | android |
I know Android has some sort of connectivity measurement, because when there's connectivity the wifi or phone network icons will turn either green or blue, depending on the Android version. In my opinion, this measurement isn't perfect, because although it will indicate accurately the absence of connectivity (e.g., lost wifi connectivity), it is not so accurate when the phone is connected to the Internet: at work, my Defy running Cyanogen 9 (Android 4.0.4) has icons that are always gray, no matter what, even when the connection is obviously up (see image below). I wonder how, exactly, Android measures the connectivity status . Is it by performing a ping or other sort of probing of a server? By listening to a port? By testing if some protocol is enabled? Or what? stackexchange-url ("This accepted answer") to a closely related question doesn't seem to answer it. | All of the information about it is pretty vague. Probably because they don't want people attacking a particular Google server. For instance, the Samsung Galaxy Tab 10.1 owners manual has this to say: Note: Network status icons turn blue if you have a Google Account added to your tablet and the tablet is connected to Google services for syncing your Gmail, Calendar events, contacts, backing up your settings, and so on.

I have a Galaxy Note (N7000) device running stock Android 4.1.2. I was browsing the internal storage and noticed a directory named ".MySecurityData", which contains one single directory "dont_remove", which contains multiple directories whose name consists of hexadecimal characters of length 32 (presumably MD5 hashes). All those 3rd level directories contain three directories - ".image", ".thumb", and ".video". A search through <code> find </code> command reveals that all the directories are empty containing no files. Fact that the parent directory is hidden, directories have suspicious and obfuscated names, and a web search returns no results for ".MySecurityData" has raised concerns of some malicious activity. Can anyone identify the application that may have created these directories? I'm a paranoid person and usually shy away from installing apps, and double check the ones that I'm installing. There is also a SQLite3 file inside "dont_remove" (name is again in hexadecimal characters of length 15).

Initial situation: A RESTful webservice defends against CSRF attacks by using the double submit cookie approach. This means that the authentication token gets submitted twice and verified at the service side. Problem / Security Threat: The WebView element of the android and iOS plattforms allow to create a malicious web browser that unveils and modifies session cookies. <code> webView.loadUrl("javascript:document.cookie=’’;"); </code> . If the attacker already figured out, how the double submitted cookie looks like, (In this case it's the AuthenticationToken) he is able to create a malicious RESTBrowser. Therefore he adds the already known CSRFToken to the document object model and thus bypasses the CSRF countermeasure. Is that right so far? Possible Preventions: So far I have no idea how I can prevent an attacker from creating und publishing such a malicious mobile application, as well to prevent the service from beeing accessed via malicious mobile applications. I know about the existence of the <code> User-Agent </code> header and that the service can use this information to reject requests from others than specific browsers. But I'm sure that also this header can be manipulated within the WebView. What are effective countermeasures aginst CSRF in contex of malicious mobile applications? | Does a malicious android WebView break the DoubleSubmittCookie countermeasure against CSRF? Short answer: no. Long answer: CSRF exploits the trust that a site has in a user's browser. CSRF protection is not intended to protect the server from a malicious user agent or from an untrustworthy user. The user is responsible for choosing a trustworthy browser. | Does a malicious android WebView break the DoubleSubmittCookie countermeasure against CSRF? | android |
Today I bought a tablet Samsung Nexus 10, it came with latest Android 4.3 installed. Android 4.2 and higher supports multiple user accounts which is awsome. My question is, if let's say I have Facebook application installed on two accounts, does it install it two times (taking 2x place necessary) or is it efficient and it installs it once and changes only login settings for seperate users. | The second user will have to explicitly install the wanted app (in your example: Facebook) – as otherwise all accounts' app drawers would be cluttered with a bunch of apps not wanted by everybody, except for those who installed them. But if the app already had been installed before by another account, it will rather be a "fake install" (i.e. it appears as if the app would be installed anew, but it's not downloaded again from Playstore, and thus doesn't consume "double space").

My daughter's Droid Incredible 2 is mostly dead. Symptoms: If we can manage to turn it on, it only stays on for a minute or so after it completes all of its start-up tasks. Then turns off and acts like the battery is dead. When I plug it in, I usually get a rapidly flashing amber light, rather than the steady amber light (for charging) that I would expect.

When I go to "Manage Apps" and view the "Downloaded" section, the indicated amount of used space first shows a high value then drops slowly while the system calculates the space used by each app. After around one minute it finally displays a value which is up to 100MB less than the initial value. I had always assumed that the final value was the correct one but recent experience suggests that the first value displayed is what is actually available for installing apps. So, can anybody tell me what is actually happening here and how I can reliably measure the free space? | You should be able to execute the <code> df </code> command from within any terminal app or via <code> adb shell </code> . It would list up all available file systems and their "free space" ( <code> df </code> stands for "disk free"). But you would need to know what is what there. To give you an example from one of my tablets: <code> shell@android:/ $ df Filesystem Size Used Free Blksize /dev 430M 64K 430M 4096 /mnt/asec 430M 0K 430M 4096 /mnt/obb 430M 0K 430M 4096 /system 674M 331M 343M 4096 /factory 127M 18M 109M 4096 /data 2G 505M 1G 4096 /cache 127M 18M 109M 4096 /storage/sdcard0 4G 650M 3G 4096 /storage/sdcard0/external_sdcard 29G 2G 26G 32768 </code> So just like Cinderella you have to pick out the good ones, but simply can ignore the rest (or you can take a look at stackexchange-url ("Android Folder Hiearchy") to learn the important ones): <code> /system </code> is where your OS and its system apps reside. Rarely interesting to the end user, as it's not writable (except you can make it such on rooted devices) <code> /data </code> is your "internal storage" <code> */sdcard* </code> (differs between devices and Android versions) your internal or external SDCard (see next item) <code> *external* </code> (may be <code> external_sd </code> , <code> external_sdcard </code> , <code> ext_sd </code> , ...) is your external SDCard. If that entry exists, the one mentioned with previous item for sure is the internal one. So in my example there's enough free space available: 1 GB on <code> /data </code> (internal storage), 3 GB on internal SD, and 26 GB on the external. As these values are yielded by the system itself, one should be able to trust them :) Remark: I ommitted some of the <code> df </code> output to make it better readable. | Variable amount of free space indicated in "Manage Apps" | android |

Is there any way to have a Samsung Galaxy S3 remind the user to rotate the device when shooting video or photographs? The user in question keeps promising to start rotating the device when photographing but always forgets. I do understand that the problem might be the wetware and not the hardware, but I argue that the form factor and UI of the device actually encourages this behaviour. | That looks like a job for Tasker : Profile CameraRotate: Condition: App → Camera Task: Notify Sound (Text: "Rotate me, please!", Sound: [select file]) This way, whenever the camera app becomes the active (foreground) app, a notification will appear with the text specified. You can also include a sound (maybe something annoying or shocking, to make the "user in question" really aware). Also, instead of the notification you could chose "play sound", and have a pre-recorded MP3 played saying/shooting something like "Hey, don't forget to rotate the device!" | Rotate reminder in camera | android |
I was looking for a reliable list of available Android browsers for the purpose of comparing features, standards support, engines, and the like. At first I thought something like this would be pretty easy to find! (Spoiler: I was wrong ) A Google search for "List of Android web browsers" returned blogs , a few arbitrary "Top 10" lists , and outdated forum posts . (Along with a mix of unrelated results). The highly informative Wikipedia article titled List of web browsers includes many mobile browsers. However, the article does not explicitly specify which platforms the browsers are available on. That "Mobile" section of the article above contains a link to Wikipedia's Mobile Browser article, which has a section titled Popular Mobile Browsers which also does not specify platforms. Compro01 Points out that there is a limited list immediately blelow the "Popular Mobile Browsers" list for "Microbrowsers", which includes platform availability. Unfortunately, it's a very limited list. Searching for "Web browser" in the Play Store returns a lot of results which are not very well-suited to at-a-glance comparison.

I am trying to root my Galaxy S2. So I followed instructions online, I booted in debug mode, connected the USB cable then pressed the up powerbutton to start the mode, I then opened up Odin v3 3.04 and it showed up with a device connected. I selected the correct .tar file under PDA and clicked start. It says "setup connection" and freezes at that. I tried redoing it because it wasn't working. Eventually I decided to see if it was just the program. I opened Samsung Kies and it couldn't connect. It tried connecting for a long time and eventually just gave up. The weird this is that when I plugin the USB cable my computer actually recognizes it as a Samsung Device because the first time I plugged it in it installed drivers automatically using Kies. I tried using different USB ports, tried using a different cable and I tried charging it. I couldn't tell if it was fully charged but it charged for 8 hours so I'm sure it was charged fully.

Recently, I upgraded my htc-desire with a bigger SD Card with a partition of 512Mo on it. I installed link2sd to place apps on SD card <code> ext4 </code> partition. Then I had to create by hand, the mount script to have my partition used by link2sd . (certainly due to write access on <code> /system </code> mountage) What I wander is if there is a way to ensure that on reboot, linked apps create their dalvik-cache directly on SD. What is happening on startup is that I need to open link2sd , select all my apps, and relink everything. Is it a feature included in the mount script? Or is it simply the way link2sd works? PS: what is anoying is that the dalvik-cache takes too much place and can prevent some application from starting correctly. | Unlikely to be possible in this context, as Dalvik cache has a fixed system-wide location ( <code> /data/dalvik-cache </code> ). So you cannot have "linked apps place their dalvik cache directly on SD". Either all or nothing. Take a look at the app2sd stackexchange-url ("tag-wiki") for alternative approaches which might allow to move the entire dalvik cache to your SDCard. But a selective move IMHO is impossible. Remark: An exception to this general rule are odexed ROMs, where the <code> .odex </code> files sit in the same place as the app, at least for system apps . So there might be a way to do the same for "user apps" which I have missed.) | How to ensure dalvik-cache and lib are linked to SD on boot? | android |

When I successfully copy my music to my SD card, each song only plays for a second and then continues onto the next song. I was able to remedy this by copying each song over individually, but obviously this is untenable in the long-run. Might this be an issue with my new SD, am I copying too fast, or what else might it be? I was able to replicate this for skipping to the center of a song. I can't hear an entire second, but it does seek to the center of the song and play a bit of it. If I try to go back to the beginning of the song after every skip, the Music Player eventually crashes. For any of the mp3s with these issues, stackexchange-url ("if I restart my phone it deletes these songs"). | The most obvious explanation is that the file is incomplete: there's only a small fraction of the file there, or only the first section of the file is readable. Given that the symptoms you report in your other question point to SD card failure, that seems the most likely cause for this too. If this is a different SD card, it could be that the card itself isn't at fault: rather, whatever you're using to copy files to the card could be corrupting the filesystem, or a dodgy USB connection to a card reader could be interrupting file transfers. | Music only plays for a second and then ends? | android |
I have some new music on my SD card and Winamp it's not showing it. How can I load the new files. | According to the information wormed out by the comments, the culprit seems to lie in the way the files have been transfered – as the transfer method chosen obviously didn't trigger the media scanner. Explanation: Most media players rely on the media database (a SQLite database) to find available tracks, as a simple database query is both faster and less battery consuming than scanning all available storage. Hence the latter is left to a single app, the so-called Media Scanner . Once triggered, it scans all available storage and feeds its finds to the SQLite database. This Media Scanner is triggered by different events: following a device boot ( <code> boot_completed </code> ), mounting a storage (e.g. putting in a SDCard), and unmounting from USB Mass Storage are some examples. So if the files were copied e.g. via some WiFi app, and the Media Scanner had not explicitly been triggered, those players won't find the new files. Work arounds you can assume from the explanation: umount/mount the SDCard, or reboot the device. Both not really elegant. Alternatively, check the Playstore for some helpers like SDrescan , Media Scanner , or Rescan Media , which are simply triggering the Media Scanner when you tap their Widgets. | WinAmp not loading new mp3 files | android |

I have a Samsung Galaxy Tab 2 7.0. I have files on an external SD card but I cannot mount the tab as a usb drive from my computer - I cannot find a way to turn on USB Mass Storage. How do I do this in JellyBean? | Starting in 4.0 (actually 3.0, but few devices used that) , most Android devices use the MTP ( Media Transfer Protocol ) class rather than the Mass Storage class. This was done for various reasons, including the annoyances attendant to having to unmount the SD card from the Android device to access it from the PC. Samsung has embraced this new way rather fervently and doesn't allow mass storage at all under normal circumstances (If you have root, you can force it on some devices . Not sure if it works for a Tab 2). MTP mostly "just works" on Windows since XP and on Mac, though getting it working on Linux can require a bit of effort if you don't use GNOME.

When the my Nexus 4 is called, the telephone caller can only be heard when loudspeaker is switched on or with earphones - is this normal? - is this a case for warranty send-back? | No, it's not normal. The following might seem obvious if you're familiar with Android, but it's worth a check. Android has separate volume levels for media (such as music), notifications, and in-call. It also has a separate volume level for when you're using headphones, to avoid deafening yourself by plugging in headphones when the volume is high. It could be that the "in-call without headphones" volume is very low, and the other volumes are normal. Try turning up the volume (with the physical volume keys) while you're in a call (with no headphones plugged in), and see if that solves the problem. If not, it sounds like a hardware problem with the speaker that goes next to your ear. There is a separate speaker for when it's on speakerphone, or for music or videos. In that case, a warranty claim would be the appropriate course of action, especially if this is a new phone and it has always had this problem. | Caller cannot be heard | android |
Do you need a special charger for a Nexus 7? I've been trying to use the same charger as I use for my Android phone and it works poorly. If you tilt the tablet upwards it's charging, but otherwise it's not. What's the deal with these Android tablets? | No, you don't need anything unique. While it comes with something specific - it can charge off a USB in your computer (or the wall outlet -> USB).

There are complaints of the 2013 Nexus 7, mostly related to odd behaviors with touch. Perhaps this could be another manifestation... Though I somewhat doubt it.

I've been using ICS on my Samsung Galaxy S3 for a while now, but I can't update to Jelly Bean for multiple reasons. I've decided to switch to Cyanogen Mod, is there any way I can move to Cyanogen without losing any application data? | As stackexchange-url ("geff described"), you cannot avoid a wipe/factory-reset. But you can do a proper backup beforehand, so you can restore most of your data afterwards. This should work without any trouble for the apps you've installed yourself ("user apps"), while special care must be taken for pre-installed apps ("system apps"): As data structures (inside their databases) might have changed, a simple restore (replacing the databases) might break things and even render those apps unusable. Provided your device is rooted, Titanium Backup is a good choice. Backup all "user apps" and their data, plus the "system apps" and their data. Special care on restore: "user apps" can be restored 1:1. Before goint to the "system apps", make sure to turn on TB's "migration" mode. Then restore only data , and do so one-by-one, after each "data set" verifying there are no side-effects. An alternative to be named is Helium Backup , which even works on non-rooted devices. Safest is to stick to your "user apps", and let contacts etc. solve via sync.

I own an HTC Salsa with Android 2.3.3 (Gingerbread). The problem is that I can't download apps like Subway Surfers , Temple Run , Candy Crush , etc. The market reports, "your device is incompatible". Does it mean hardware requirements? Is there any way I can upgrade my phone to play the above popular games? Update: Very useful information from Mr. Buster. But since there is an update on GOOGLE play now, which doesn't allow you to see the incompatible information. Screenshots (click images for larger variants) | Application developers can set their own requirements in the play store for what must be present before a game or application will be available. For example, it is possible to require a device has a camera, or has a screen larger than a given size, or has support for a particular version of OpenGL. The HTC Salsa is equipped with an ARMv6 CPU (MSM7227), and has an Adreno 200 GPU, which supports OpenGL ES 1.0 and OpenGL ES 1.1. From experience, the limitation here is most likely your ARMv6 CPU, as the vast majority of sofware nowadays is written for ARMv7 capable CPUs. Googling for the names of these games, along with "armv6" shows some hits, although I would be very cautious about running third party unofficial apps that have unspecified and unverifiable modifications. If you do manage to get the games to run, you may find they lack OpenGL support (modern games are usually using OpenGL ES 2.0 or above), considering the fact that OpenGL 2.0 is required for programmable 3D graphics (source: http://www.khronos.org/opengles/2_X/ ) | Why am I unable to install some apps? | android |
Lately I had issues with my phone's (Samsung Galaxy Mini GT-S5570) internal memory aw well as with the SMS memory. I deleted all unwanted messages, rooted my phone and used <code> Link2SD </code> to move some apps as well as link other ones on my SD card. Yesterday I installed some apps from Samsung Apps and I am facing a rather weird situation. Note that before the installation I had ~20 MB free phone memory. All those apps are installed on the SD card(at least that's what Link2SD says). The moment I finished the installation I got the error message that my phone's internal memory is nearly full I used <code> APPMGR III </code> to see what is my free memory and I found out that I had only ~5 MB left! I was so surprised! I decided to delete all the new apps only just to find out that after that I had only ~12MB free! Why did that happened? I checked to see if any app cached but everything seems OK. I keep having the message about the internal memory as well as the SMS one. How can I fix that? Where did my free memory go? | Link2SD only moves the app itself to your device's SDCard. App data still go to internal storage ( <code> /data/<package_name> </code> ). For every app you install, the Android system automatically creates this directory – and I don't know of any app that doesn't put at least a few files here. For details, please take a look at the stackexchange-url ("app2sd tag-wiki"). It not only explains the different App2SD approaches taken (including Link2SD ), but in "Extended Methods" also holds hints for a possible solution to your problem ( S2E ). | Why an SD-card saved app uses phone memory | android |
I applied the procedure to unlock a Samsung Galaxy S3 on a Samsung Galaxy Express I437. It went through smoothly, and but the phone was not unlocked.

Device: Galaxy S4 Android: 4.2.2 I have been looking through the <code> Settings > Accounts > Add account </code> menu and found there is an entry called "Server" that seems to allow you to sync calendar and contacts from a private server.

I'm trying to setup my Gmail account in K-9 Mail, but when I'm setting up the incoming server, I keep getting the error: "Wrong username or password". When I'm trying to set up an outgoing server, I get an error which directs me to the two-step verification at Google.

I've searched all over and tried following different guides, e.g. stackexchange-url ("this question"), and I've also tried to change the password on my Google account but nothing helped. How can I properly configure K-9 Mail for my Gmail account with 2-step verification? | IMAP clients generally need to use application-specific passwords in order to access accounts that use 2-step verification. You'll need to generate a new app-specific password, then use that to set up your incoming/outgoing servers instead of using your regular account password. Google's support page (linked above) includes instructions for doing this. Summarized, the procedure is: How to generate an application-specific password Visit your Google Account settings page . On the left, click Security . Under the "2-step verification" topic, click Manage your application specific passwords . Under the Application-specific passwords section, enter a descriptive name for the application you want to authorize, then click “Generate application-specific password". You'll then see the application-specific password (ASP) you just created. You'll also see the name you wrote in for the device and a link to Revoke -- or cancel -- the code. When you sign in to an application requiring an ASP, enter your ASP in the password field, and make sure you check the "Remember password" option if you want the application to remember the code. | How do I setup a Gmail account with 2-step verification in K-9 Mail? | android |

The title pretty much states my question but mainly I want to know if I say hope a flight in NY to California will android pick up on the time difference between the time zones?

I'm a teacher in the UK and have 30 kids in my class.We have bought 35 (older) Nexus 7 tablets. I have one Google account which I want to use across all devices so that the young children don't have to remember user names and passwords. The trouble that I'm having is that not all of them are able to be logged in at once. There appears to be a limit as to how many devices can be online with this account at once. We're doing this to be able to use Google Drive so that the kids can produce work and save it into Drive. We are finding that as tablets are booted up, already online device are logged out from Google and I have to log them in the android backend. I'd love to get this sorted. It's for the kids! | This is as close to an answer as I can find at the moment. Looking at the site for the (soon to be launched) Google Play for Education site, one of the benefits that they mention is: For Educators Android tablets in the classroom Google Play for Education brings the innovation of Android technology into classrooms. Educators can set up and deploy large numbers of devices in just minutes or hours rather than days. ...

They can send the apps to individuals or groups of any size , across classrooms, schools, or even districts. (My emphasis, from http://developer.android.com/distribute/googleplay/edu/about.html ) Which sounds promising, but if you go to the Sign Up/School Interest Page it has this interesting bit of wording on the form: Which suggests that there's a limit somewhere around the 30 device number. Which would match up with what you're seeing. As I can't find anything else official mentioning this limit, I can't find any official advice for getting round the limit either, sorry. | Many devices for one android user.

I have a Samsung S3 mini, no support for SD cards so i had to root it, and install Link2SD, spent the last 3 days hacking my phone making it better. But i have questions, in all the tutorials everywhere on the web, they say ( I refer to this blog but there are many other blog posts and xda posts and youtube videos that say the same) if you have stock rom, use ext 2? (isn't ext 4 supported?) partition your SD card, the max for your apps is 2 GB (I have 8 GB,why can't I partition it like 6 GB for apps, and 2 GB Fat32 for music, OR all of it ext2 or 4 and add whatever to it?) You install link2SD first time, it asks for root permission, it asks what partition type you're using (ext 2, ext 4, whatever) and it asks to reboot the device, that's fine. But when you install it second or third time, it only asks for root permission, it doesn't reboot the device nor what partition type you're using. Why? maybe I changed (and i did change many times) the partition type, it doesn't ask, so doesn't detect it. Once linked, what is the location of the apps? ( <code> data/app </code> is empty, though i haven't move everything) Sorry for asking too many question at once, but link2sd is not a big deal, it doesn't deserve asking many questions about it so i tried to put everything in 1 question | yes, stock rom does not support other file systems but EXT2 for the second partition. So create an EXT2 partition. the location of the apps, once linked with link2sd will be from the root of the sytem: \ (which is root) sd-ext and there you will find some directories or app-files, depending on your link2sd settings. About the question for mounting / rebooting: I cannot answer that because I do not know. about the size of thee partition: when you connect your phone to your computer, and have minitool partition wizard installed, you should be able to create the partitions like you want it and with the size you want. But to be honest: 6gb for apps is an awfully lot... I think the tutorial just points out that you probably never will exceed the 2 gb that is mentioned and you can use the other 6gb for normal storage (which also can be read by windows when you connect your phone to your computer) I hope I answered your questions... | Questions about Link2SD and SD card partitioning | android |

I have a Verizon Razr M that was given to me for free. It's a Verizon model, but it has never seen a network. (I use it as an WiFI android iPod touch for now) I know about CDMA/GSM/4G and all that. But doesn't it have a 3G radio for roaming? I don't need it to ever hit 4G/LTE/CDMA, but it would be nice to have it see 3G networks for me to drop a cheapo SIM into when I go out. Is this possible, or is this hardwired into the baseband with no hope for me. Are there unlock codes for this? I'm new to rooting android,, but a root doesn't seem to help unless I can reflash the baseband. Thanks. | In a case of LetMeGoogleThatForYou , I found the answer. Turns out, it's a single byte on the phone that determines whether the phone is GSM locked or not. Someone found this, and made a nice tutorial on how to flip this byte. The instructions look scarier than they really are. The detail is not because it's complicated, but because they show every single step. The hard part for me was prepping my Windows box to be able to do this; you need Motorola Drivers and the .Net runtime for the Motorola diagnostic/programming application. | Can I unlock my Razr M (Verizon) for international use? | android |
I've had a Samsung Galaxy S3 for a little over a year now and not had too many problems with it. This afternoon, however, it's decided it won't connect to mobile data at all. I've had similar things on this and previous android phones, so I've tried: making sure wifi isn't on checking that mobile data is enabled (!) checking the AP settings (these are actually locked down by my network provider - O2 UK) turned on & off airplane mode restarted powered off & on powered off, removed the battery and powered it back on In all cases, I get no mobile data icon (so it's not even trying to connect from what I can tell) and I get no connectivity. Phone calls and wifi are working just fine. Is there anywhere diagnostic information is kept around the status of the mobile data connection? If there's an error occurring, that would certainly be useful! I did drop the phone a few days ago, but the mobile data has been working fine since then... but I guess it could still be related somehow. Even if that is the case and there's a hardware fault, the same thing applies - where is the diagnostic info? I'm on the O2 UK stock image by the way - 4.1.2 / JZO54K.I9300XXEMC2 | While in this case it turned out to be a carrier issue (and solved on the carrier's end, see stackexchange-url ("this comment")), in other cases one of the test menus might prove helpful. for a starter, you can find a lot of "secret codes" in this list for the SGS , together with a short explanation.

I've just acquired Nexus 7 (2013) and can't connect it to my PCs. All drivers I have (one from Android SDK, as I'm a developer, and the second from the Android site here , named as <code> latest_usb_driver_windows.zip </code> btw) do not install either under Windows 7, or Windows XP. PC discovers new device as "Nexus 7", but wizard says "could not find the software on your computer" when I specify folder with drivers. After some unsuccessful trials, I decided to disable MTP and mass storage modes on the Nexus, just to eliminate these parts of driver - in fact I need only debugging via USB. I enabled the debugging via USB at very beginning, and it shows up in Android's notification bar, but the device does not show up in adb/Eclipse. So I switched MTP and mass storage OFF via notification area. This did not help to attach the new device. But now I can't enable either MTP or storage mode back. They are missing in notifications, and they are missing in Settings -> Wireless & Networks -> More, where they are supposed to be. So the question number 1: how one can switch MTP and storage mode ON in Android 4.3, specifically on Nexus 7 (2013), other way than via notifications? I saw similar question on the Internet, and the only answer was to reboot the device - in some cases (from time to time!) this worked for someone. I restarted Nexus, but still nothing USB-related shows in settings. Also I'd appreciate any clues on how to connect Nexus 7 (2013) to Windows PC? I should mention, that I have Nexus 7 of the first version, and I'm able to debug apps using it, that this first Nexus is connected to the same PC successfully. This brings another problem, because I do not want to lose connectivity with the first device by complete removal of drivers, because I have no guarantee that after this the first device will not become lost in the same manner as the second. Thanks in advance. | I'm posting the solution (as @DanHulme asked me) despite the fact that it's trivial. If you already use latest drivers and have no option to reinstall a part or entire system, the only way is to keep trying with what you have again and again. I don't know what exactly happened, but after a day of trials (plugging the new device and removing it, pointing the system to the drivers in this way or another) it was finally connected. As for the other side-question about MTP, it was actually answered by @eldarerathis in comments: MTP mode can be enabled/disabled in Settings > Storage > (overflow menu) > USB computer connection. | USB connectivity problems with Nexus 7 2013 | android |
