Is this a shopping question or do you like to know how to upgrade your device to 4.3?

I already have the tablet. I need to upgrade it to 4.3. Its manufacturers don't release any update. So I need to check if it can afford 4.3 or any version after 4.0

353MB is probably too little for a proper 4.1+ experience.
Besides this, there's no generic Android installation media, each device needs its firmware tailored and adapted by the manufacturer. If the manufacturer has put it end-of-life, you're hosed unless you find someone who ported it or you port it yourself.

OK, so I will have to stay with what I have. Anyway Thank you for the help +1

Why is Music Player deleting my music?
I recently installed a new SD card in my phone, so I moved all of my music from my phone to my SD. After I moved my music, I noticed that all of my soundtracks were corrupted. Each of them only had about 5 songs and I couldn't play them. I followed the instructions here, deleted my Music Player's application data, restarted my phone, etc., and then my soundtracks were completely gone.
Alright, something must have happened during the copy right? So I copy my soundtracks back to my phone, try to open them in my file browser, and it says:
Sorry, the player does not support this type of audio file

For mp3s that I was playing just yesterday.
So I restart my phone again, and what happens? My files aren't even there. Soundtrack folder is empty.
Anyone have any thoughts on what's going on?

That looks very much like a faulty SD card, doesn't it? I'd suggest you put it in your PC and test it thoroughly with a badblocks program.

Any non-Linux suggestions?

On Windows, if you right-click on the SD card "drive" and click Properties, there's a button in there somewhere. I don't know how to do it on Mac OS.

Good, then I'll run it when I'm on my Windows box.

That sounds like a bad SD Card. Insist doing that over and over again, with sound files and movie files as well.

I received it yesterday from an individual vendor on Amazon, so maybe it is a dodgy SD.

Do not trust them anymore... buy from official store, it is expensive but you will not have any surprises

Agreed, I'm probably going to try returning it tonight.

I believe this is not specifically to do with your SD Card.
Did you have songs in a play list?
I find my music is fine unless I add it to a play list, if I do tracks get deleted.

I believe I had one album that I was listening to at the time which was still getting deleted, but yes, the majority of the music I was listening to was on a playlist. I haven't had the problem since I got my new SD card, so I think that was it.

Music only plays for a second and then ends?
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, 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.

On some files I could fast forward halfway through the song and it would do the same thing, play a second or so and then move onto the next file. The transfer cable is only a few months old, though I'll try to pick up a new one to compare. I'm using MTP to transfer my files through my phone onto my SD. How reliable is that protocol?

If you can skip to and play any second of the song this way, not just the beginning, that doesn't sound like an incomplete file. You should hold off replacing the cable until someone has a better explanation.

Yes, I was just able to replicate it and 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.

@NobleUplift Edit this information into your question. Then others are more likely to see it and propose a new answer. Right now, people will probably assume my answer is correct, without reading the comments at the bottom.

I had this problem. The song worked fine in iTunes, but not in Google Music. The song has an audio glitch in it from recording it from a burned CD, and that is around the spot where the song skips. It's not the MP3 or the song; it's something about Google Music doesn't like the song.
My work around: I made an AAC version in iTunes, uploaded that, and it worked. So my original mp3 must have been glitchy.

An incomplete songplay is mostly due to the corrupt file which you have downloaded. Although it may show around 7 MB for a file, if the file is corrupt, then it won't play any part of it, or in some cases, just plays the start and skips to the next.
What exactly a corrupt file is
A corrupt MP3 file means that some audio bits and tunes are missing or contain some bugs. The MP3 player usually plays these bits if all are there in the proper order. If some bit of data is missing, then it simply skips to the next track.
The corruption of the file can be judged by the amount of file that is playable. If you can only play the start, then the whole MP3 is corrupt. It is a waste of trying because sometimes you could get only to the middle and later by default, it skips.
Detect a corrupted MP3 or MP4 file:-
The best way to check a corrupted file is to do a simple fast forward (don't do a 4x fast forward for you will not know when the file is fast forwarded very fast) till the end of the file. In fast forward, it will skip to the next available data point. As you are able to only fast forward till the middle, the remaining portion of the file is missing/corrupt. If fast forwarding jumps directly to the last, then the whole song is corrupt and needs to be deleted.
For an MP4 file, when the video turns pixelated during a fast forward instead of the smooth audio/video, then that video is corrupt. A complete video plays the audio and video with ease even if you fast forward.
If the file is partially or completely corrupt, you have to delete it because a corrupt file will never play completely.
How to avoid a corrupt file

Always download files from a reputable source. Some sites don't have proper files, which many fall trap to. If you download from good sources, then you will not have that issue at all. (My suggestion is to avoid using free downloads as far as possible as it's against the law-piracy issues and also you got cheap audio with these kinds of issues)

There are some download managers that check for the link and file before downloading. If the link or file is missing/corrupt, then you can avoid this issue.

I had a problem like this on my default Android music player, then I got a clue to the problem.
On another player, there was a setting that said "show music less than 60 seconds" that was turned off.  Well, my music is all around 3 minutes, but not showing up. I changed this setting, and then all the music was listed and played fully.
So there must be something in the music file about length that is wrong.

I had the same issue. Simple solution, use Samsung Music app. Google apparently doesn't like it if your music library was not purchased from them. I have an extensive library of music ripped from my CD's etc. that work fine on any other music player.

Yeah, I had to use Samsung Music to generate all of my playlist files otherwise my WMP playlists don't convert to M4U.

Today I solved this: it fully depends on the embedded picture inside the MP3 file.
Please note: the MP3 files are not corrupted!
Just the picture file is reader-unfriendly (tested with 2 different readers, and both had the same problem).
So, delete the embedded pictures, or change them with a smaller or different version (with a simple batch process), and it will be OK.

When you transfer music files, do not transfer multiple files at the same time.

Steve, can you give some background on your argument so it can be understood? I assume you're talking about limitations on MTP here – but without some more details I cannot be sure.

Not only that, this is untenable for 99% of people who listen to music. MTP takes forever to startup and shutdown copy processes, and you can only have one copy process going at a time. Copying one file at a time would take years for a sizeable library.

Need to press power button three times to turn screen on using Screen Off and Lock
I'm using the Screen Off and Lock 1.7.1 application on Android 4.1.1. The phone model is Huawei G510-0010.
After I turned off the screen using that application, I have to press the power button three times to turn the screen on. Using the power button to screen off/on, it is ok.
I uninstalled 1.7.1 and installed 1.10 which already works perfectly in other devices, but still facing the same issue.

I changed my mind to use Gravity Screen - On/Off.

This app turns automatically your screen off when you put your phone
  into your pocket or onto a table and turn the screen on when you take
  it out or up. No need to touch any button and you are ready to go.

nexus 10 tablet characters illegible
I've installed two apps on my Nexus 10 tablet and the characters show up as boxes with x's through them as shown below. i'be contacted the developers of the Rosetta Stone app to no avail.
I'm in android 4.3. any suggestions as to settings or installations that can solve this problem?

Looks to me like a font/localization issue: Most likely the apps in question want to use a font which is not available on your device, and the font substituted by the system does not match the characters used. You could use adb logcat to check for related errors.

It's not saying much for the quality of Rosetta if it struggles to understand a foreign language!

@Izzy thanks, so basically you're telling me I need to plug in the device and run the program from an editor like Eclipse or IntelliJ to fix this?? yikes,I think this is more of a Nexus problem, since it happened on the same device to two foreign language programs?

Not exactly. Plug in the device, yes. Eclipse, not necessarily: You can run adb logcat from command line. I do that all the time. Recommendation: use adb logcat -f <filename> to write the log to a file to investigate, output can be quite long. See also: adb help, logcat help, Is there a minimal installation of ADB?. // And it's a "foreign language apps problem with your Nexus", yes :)

Open SWF in Chrome for Android
I can open SWF URLs in Chrome for PC, however, I cannot open them using Chrome for Android on my device.
Is there a Chrome plugin, or is there Java code that will do the mission, if there is, I will create a new Android project and program it then install the APK.
The URL that I test with is :
http://www.b7r11.com/tkber.swf

Chrome for Android doesn't support Flash, and neither do newer Android versions.

Chrome for Android doesn't support extensions, either.

What's your Android version? I'll assume you're using 4.1 or newer.
The .swf extension is used by files played by Adobe Flash Player. Unfortunately, Flash is not supported on Android since 4.1.
You can try installing the Flash Player APK. The latest version is for 4.0/ICS, but some people say it works on 4.1+/JB as well. Remember: Your Mileage May Vary™.
Additionally, Chrome for Android never supported Flash - even with the APK installed. (Thanks to Compro01 for confirming that!) So you'll need to use a different browser.
If you are not using Android 4.1 or newer, please update your question with more information.

Chrome Android doesn't play ball with flash.  You need to use a different browser to make use of the installed flash APK, which does work on at least 4.1 on my GS3.

@Compro01, thanks! That's what I suspected, and it's good to have confirmation. I've edited the answer with regard to your comment.

Furthermore, I'd recommend getting the apk directly from Adobe rather than some random source.  I edited your answer to point there.

Many thanks. I probably shouldn't have just dropped in the first result from Google.

Just downloaded Flashfox from Google Play store and issues with swf dissapeared.

No WhatsApp notification on Xperia S after updating to JellyBean
I have Xperia S running Android ICS, and the notifications of a new message of WhatsApp appeared in the top notification panel showing an icon of WhatsApp. I received an update to JellyBean and after that, I'm not seeing the notification icon when a new message is received.
If the volume is high, all I can hear is the new message tone, but there is absolutely no notification showing the new message received.
Does anyone know how to solve this problem?

Found the solution myself. In Settings>Apps>Whatsapp. There is a check box right below the Icon which says "Show notifications" Check it and it is solved.

If you found an answer to your own problem, please post it as an answer and accept it, so that the others can also get benefited from it.

From OP's self-comment,

In Settings>Apps>Whatsapp. There is a check box right below the Icon which says "Show notifications" Check it and it is solved.

Prevent LED flashing when tablet is on standby
My Xperia Z tablet has a really bright LED that flashes when it is in standby (that is when the screen is blank). In fact, I am not sure it does it all the time, but it is very annoying if it is in the room at night. Is there any way to stop this from happening?

Perhaps the app Notification Light Widget will help you. It gives you a widget to manually enable/disable the light. Can't get a lot simpler than that!
Note that tweaking the notification LED is often a hit-or-miss operation with some devices. There's no promise that it'll work perfectly. Give it a shot and let us know how it goes!

Is there a curated list of Android web browsers?
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.
Does anybody know if/where a curated list of Android browsers, perhaps with some information about features/etc, exists? (Please don't just respond with your personal browser of choice!)

Wikipedia's article on mobile browsers has a list including platform availability.  No feature details though, just the engines.

Ah, interesting. I didn't give any regard to the Microbrowsers section. That's definitely something! Unfortunately, there are only 7 Android browsers listed there. It's more than nothing though.

What's the purpose of the comparison?

The end goal is to ensure wide compatibility of a mobile version of an ecommerce site, and I'm most concerned about adherence to HTML5 standards, Javascript engines, and rendering engines. Additionally, having an idea of the update cycle of various browsers would be a plus. An ideal list would have all this information. Barring that unrealistic case, since our team has some Android phones to test with, simply a large list of Android browsers (Outside of the obvious) to test on our devices would be the next-best thing.

Well, I've wound up using alternativeto.net to specify alternatives to a specific browser, and limiting the results to Android. It's not perfect, but it's actually very workable.
It gives me a list that is fairly comprehensive, gives me an idea of user base numbers, and also includes enough at-a-glance information to help me a bit.

Based on your comment, are you looking for these things?
You can either use real Android device or lookup existing Internet resources to examine the code.
P.S. Do not ever attempt to use Android emulator to perform testing. As it is not reliable at all.

While this is certainly an interesting and useful set of resources, none are quite what I'm looking for. Ideally, there would be a very similar list, but as a comprehensive list of Android browsers (Chrome, Android Browser, Firefox, Dolphin, Skyfire, Opera Movile, Opera Mini, and the dozens of other android web browsers). In the end, I've just resorted to downloading every web browser I can find in the Play Store and testing - unfortunately, this doesn't easily give me all the information I want. However, individual wikipedia pages for each browser (that has one) are quite helpful.

Lost phone and WhatsApp issue
I lost my phone and I have some contacts on WhatsApp which I don't have anywhere else.
Is there any way to get those contacts? I have already deactivated my SIM card.
Can I get the data back?

Just wondering . Why a minus 1 for the question. I lost my ANDROID phone. And i believe this is the right place to ask as this is a forum related to android questions only !

No brother, this is a forum to ask questions about Android Phones, not the Android lost phones! :) You can ask for help by the police authorities or you can try your luck with the Android Device Manager from their site http://www.android.com/devicemanager

@AfzaalAhmadZeeshan If what you say were true, we wouldn't have a [tag:lost-phone] tag with 72 questions, many of them with useful answers about how you can safeguard data on lost phones. This question is a good fit for this site.

Sorry to say, but there is no or alternate way for this.

I had lost my phone and i was having some contacts on whatsapp which i dont have anywhere else.

This thing is a bit wrong, because Whatsapp would use your own phonebook to check which of your contacts have whatsapp. It won't let you add any user to your stock pile by just adding them as friends.

Is there any way to reach to that contacts .

If there is a backup of the data on Google servers, then there might be an option. But I don't think that would work! So there is no way to get them back.

I know this is not a technical question concerned with android

True, but actually this is a site for the Android questions. So you're in the correct place. To ask how to get data, but now about how to get data from a lost phone. Thats impossible.
Possible things that would help
Well these are not the helping materials, but just in case to remind you that, in the settings, did you check backup my data. If so, try signing in Google from other phone, it might give you some data.
Not sure of this but you said the contacts were no where else but on whatsapp, so try signing in to whatsapp again, maybe they still have those contacts for you!

I found nothing there.

WhatsApp does not remember your Gmail contact information. WhatsApp simply adds contacts from the phonebook. If you get a new phone and sync your Gmail account, then you will have those old contacts same as you had in old phone. That is the reason. WhatsApp primary ID is your phone number alone, not any other info.

Have you tried to go to https://www.google.com/contacts/ and see if your contacts are backed up there?
That's the only possible way to get data from a stolen device, by having your data synced somewhere.

Sign back into watsapp your contacts will be there.  I was surprised to find them there when I signed back in but using a new number. I had lost my phone. Im guessing watsapp recognises your gmail sign in so your sync contacts to your google and watsapp account will.automatically be available.

fastboot serial number?
On occasion I've seen the serial number reported by adb and fastboot differ. Is there a way to reliably determine what the fastboot serial number will be from adb?

Generally speaking, the serial number as reported by adb get-serialno will be different to fastboot as determined by:

Manufacturer
Make and model of device in question
Android version

fastboot, on the other hand, since there's no adb loaded, instead, it uses a rudimentary USB protocol tied in with the boot-loader, the serial number will be different.

Is there a way to reliably determine what the fastboot serial number
  will be from adb?

There is no reliable way of achieving it.

Just to be thorough, not even adb shell cat /some/file?

Rooting Android Galaxy S2 - Connection Error
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. Still didn't work.
After researching for 2 days and trying endlessly, I decided to see what you guys think.
So let me know if you have ideas! :)
I tried uninstalling and reinstalling kies, now it is connecting with Odin but it wont connect with kies at all. But its now showing this error.

I know its the sliding one, but its with Rogers and that link doesn't list any Galaxy S2's with sliders. It also doesnt have a button, it has touch buttons with 4 at bottom if that helps.

I followed this guide rooting mine:

Be careful with odin. When you're editing your bootloader. You can brick your device if you do it wrong, and then your only option is JTAG repair, which will cost you ~$50

How to ensure dalvik-cache and lib are linked to SD on boot?
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 ext4 partition.
Then I had to create by hand, the mount script to have my partition used by link2sd. (certainly due to write access on /system 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 (/data/dalvik-cache). So you cannot have "linked apps place their dalvik cache directly on SD". Either all or nothing. Take a look at the app2sd 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 .odex 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.)

Thanks @Izzy, that answered my question, for my needs I finnaly added a dummy .dc2sd file on my /sd-ext so  etc/init.d/10apps2sd script move all the dalvik-cache to sd and nuke the one on internal memory.

Thanks for your feedback, Yannick! So just for me to understand: On each boot, that script moves the Dalvik cache for the "marked" apps to SD? Doesn't that mean that on the next boot, Android will re-create it in /data/dalvik-cache? If so, what does the move improve (except for "temporary relief")? To me this looks dangerous. Imagine a few apps with a larger .dex, and think of low internal storage space when you reboot the device (because you installed one more big app, thinking you had the space) – and now Android rebuilds the .dex on internal storage, running out of space.

The script 10apps2sd from Evervolv Project coming in my ROM mount /sd-ext/dalvik-cache as the /data/dalvik-cache so all .dex goes on sd-card. For the risk of big apps, I'll keep that in mind, I can install them on SD or make the symlinks with link2sd. So if the sd-card is not available those won't prevent system to load as system should have space.

By the way, my HTC-Desire came with a 148Mo internal storage you might understand the need moving apps and data on external memory.

One last thing as a feed back, don't let [tag:link2sd] try to link [tag:dalvik-cache] that is already present on sd-card. It will make a loop symlink on itself. :(

Right: If the app is on sd-ext, and sd-ext is only mounted after boot_completed (as it is the case with the "normal" SDCard), this problem should not arise as the system should not see those apps. Forgot about that, sorry. And I never doubted the reasons for moving apps to SD :)

Request Persmission after changing Google password
I changed the password on my Google account a week ago, and ever since then I've been getting notifications on my Nexus 4, requesting permission for my account. When I press it, nothing happens, but Google Play Services appears in the recent apps menu, and nothing happens when I press it.

I had the same problem, it's a bug that appears occasionally when you change your Google account password, or when you switch to the two step verification. Some apps that are using your Google account can't synchronize the new password and this error appears.
In my case, the guilty was the app "My Tracks" (from Google) (https://play.google.com/store/apps/details?id=com.google.android.maps.mytracks&hl=en). Going to "Settings > Apps > My Tracks", claning data and cache and relaunching the app solved the problem.
If you don't have "My Tracks" app installed then try this:
Go to "Settings > Accounts > your Google account". Start unchecking one of the options and select "Sync now" (in the menu). Continue unchecking the rest of the options one by one and doing "Sync now" until the synchronizing error stops appearing. At this time, go to "Settings > Apps", search for the last app you unchecked, clear its data and cache and relaunch it (the app may ask for permission, you have to allow it). Then return to "Settings > Accounts > your Google account" and check all the options and do "Sync now". If the error continue appearing it means that another app is failing, so repeat the operation to detect and correct it.

I don't see any reason to believe the OP is using this app.

Software recommendations-type like questions are not welcome to this site or any in the SE network. And that is probably, why your question got -1.

I've found Meridian Player Transcend and it's what I needed. I can play all the mp3 files from a folder (all songs in an album)

WinAmp not loading new mp3 files
I have some new music on my SD card and Winamp it's not showing it. How can I load the new files.

By fixing the issue. Honestly, we need some more details – as it stands currently, it's hard to tell anything. Where did you place the new files? Does any of the folders contain a .nomedia file? How did you copy the files there? Has the media scanner been run after the copy? Do the files show up with other music players?

I created a folder named Music and there i put the mp3 files. Last time Winamp didn't show any artist/album.

OK, so what about the other details? HOW did you put the files there (describe the steps), is there any .nomedia file, are the files shown by other players?

i just opened winamp, after ~1 day and it displays the songs

i plugged the usb cable and copied the files on the sd card

And for that the device used MTP I guess; would it have used UMS (USB mass storage), the media scanner would have updated everything automatically as soon as you disconnected your device from the computer, and the SDCard was available locally again. // But as we finally figured out, hopefully, I hope my answer is useful to you and able to solve the issue. If so, you might wish to indicate this by "accepting" it (clicking the checkmark next to it). Good luck, and enjoy your music! Glad it finally showed up :)

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 (boot_completed), 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.

Signature verification failed when flashing custom kernel (Siyah)
I am trying to flash a custom kernel (Siyah-s2-v6.0b5-CWM) to my Samsung Galaxy S2.
When I go to recovery mode, click apply update from sdcard, and select the file, it shows this:
Finding update package...
Opening update package...
Verifying update package...
E:signature verification failed
install_package = (2)
installation aborted.

Any ideas what to do?

Is your phone still using the stock recovery? That may be the problem.
If you're trying to flash / update ClockWorkMod (CWM) zips, then you need to have CWM recovery on your phone. An easy way to install CWM would be described in this answer; needs root.

Navigation Voice is not changing
Hi I have got Samsung Galaxy S4 Active.
I have downloaded Samsung's high quality British English TTS engine and set it as "Preferred TTS engine" From Settings -> MyDevice -> Accessibility -> Text-to-speech options -> Samsung text-to-speech engine -> Languages
However when I use Google's Navigation app, it still uses Google's TTS engine.
Furthermore I actually disabled google's TTS engine so it is not present at TTS options, the problem still persists!
The only thing that I have discovered is if I change preferred language from English UK to English US, then TTS engine changes in Google's Navigation App from Google's English UK to English US!
I thought the problem is at Samsung's TTS Engine. So I downloaded Ivona TTS Engine and tried same languages and experiencing same problems with that too.
Is there a solution for this stubborn Google's Navigation app's voice?

On my Samsung Galaxy S3 with Android 4.3, Google Maps uses low quality female US voice no matter what TTS setting I specify. Downloaded and activated UK high quality HD female Google and Samsung TTS packs, but Maps always uses low quality female US.

Google's navigation voice has always been some google related voice. The only option might be is if you download a high quality version of one of the google voices. I personally have never been able to change the voice used by Maps/Navigation.

Google Maps always uses the same voice, regardless of TTS settings. It's totally separate, and you can't change it.

If all you want is a British voice, then you don't have to downgrade from Google Maps version 9.32.1, there's another way:

SETTINGS > LANGUAGE AND INPUT > LANGUAGE > English (United Kingdom)

This changes the language settings for the entire phone, but I haven't noticed any major difference, but I do love having a British girl's voice give me driving directions and the audio quality is almost as good as the Ivona British voice.
I used to use Ivona but prefer this method now because it doesn't require installing an extra app.
Try it out and see if this helps!  It's easy to go back if you don't like it.  Just change it back to English (United States).
If it doesn't work, then please make sure that:

TEXT-TO-SPEECH OPTIONS > Google Text-to-speech engine

is selected.  And while you're in that screen, download the speech data for that language:

GOOGLE TEXT-TO-SPEECH ENGINE "GEAR ICON" > INSTALL VOICE DATA > English (United Kingdom)

What's also cool about this method is that your Google Now girl now has a British accent as well!
Hope this helps! :)

In the Google Play Store, uncheck the option to Auto update maps.
Uninstall Maps (or updates to maps if it is a system app).
Install (or update) to Maps version 9.1.2
Disable Google TTS engine.
Reboot phone.

battery drainage question on HTC Sensation
HTC Sensation Z710e is one of the phone I have used over years. I found out that this handset’s battery drains extreme fast and I tried to find out some ways to reduce the battery drainage and make battery performance better. I got a replacement battery for Sensation from a friend and this is helpful.
I think it probably because I are using the stock battery for too long time? it is also easily got hot now...so how long can a stock battery actually be used??

well it depends on the how you use the phone. Frequent charging is one of the ways the battery life is affected negatively.Also let the battery drain completely before you start charging.Do this atleast twice a month.It increases battery life. Also do not overcharge the phone.

Frequent charging does not noticably affect battery life of LiIo batteries, that's a myth. What does affect it is "running it low" (also called "deep discharge", or "complete drain"). So following your advice to let the battery drain completely before you start charging actually shortens its life. See also: How frequently is it okay to let the battery discharge fully or as low as possible? "Overcharging" is another myth, as the battery controller prevents such.

Install a wakelock detector. Wakelocks don't allow your phone to conserve battery life like it's intended to. The detector will tell you which apps to uninstall. Something is probably pegging your phone processor or wifi.

my phone is stolen and sim cards removed. how to track it?
my android phone got stolen a few hours ago. the thief has already removed both the internet sims.
as such, i had not installed AndroidLost or Mobile Tracker apps in the phone as it is a relatively new one.
i have tried to remotely install it, but it may take time .
please help out with the procedure and suggest methods to get it back.

do you have the IMEI number of the phone? It maybe mentioned on the reciept of your purchase.If you got it you can give it to the police to track and they will be able to find it

or from the link that @Sid suggested, you can try the plan B from the play store and use that.

Keep in mind that any solution mentioned here and in the linked question only works as long as the device has not been factory-reset (so your Google Account would be disconnected fro the device). After that, the device can only be identified via its IMEI (and a clever thief even could manipulate that).

thanks a lot people... gonna try all ways out of this. will update whether i get it back or not ..

There can be many other options instead of those apps.
Android Device Manager
http://www.android.com/devicemanager
This is the only thing to do, and check where the theif had been for a few last moments. But this isn't perfect.
Android IMEI
If you ever wondered what your phone's IMEI is, you would have checked it via *#06# too. If you have it, then go to the government officials who can handle it (I am sorry I cannot guide you to the perfect organisation for that, because I never tried using IMEI to track a phone) and they will help you either in protecting your data or will even get you to your mobile too.

Good points. Unfortunately the Android Device Manager is very far from being perfect. I've tried it with four devices, it worked with none of them (could not locate the device, could not ring it, nothing).

Yup you're right, my mother just took my phone I tried to track it and it gave me a location just 2 streets away while my mom was more than 400miles away :D But lets wait for it untill its out of beta thing :)

I doubt it will ever be. For my devices it couldn't find any location at all. And if you take a look at Google Cloud Backup, which was introduced somewhere with Android 2.x more than 2 years ago: it's still a "game of fortune" whether restore works at all or at least partially, even with 4.x devices. So no, I wouldn't trust it before having verified it works with the device I intend to use it on. But if that's verified, it's a good solution.

Whether restore would work? You can bet on it! :/ It doesn't work, and it won't work for 4.3 either! You can be sure for this. And yeah, Android Device manager just gets the last location which was sent to Google Maps and shows it. But their ringing thing is awesome :) It rings the phone just in few seconds! :) I love that..:)

How to disable Hangouts?
I have an HTC One, and I went to Settings -> Apps -> All to disable a few apps I didn't want on my phone (7digital, Facebook, Google Play Music, Google+). The apps are now gone and the update notifications disapeared for these apps in Google Play.
But for some reason Hangouts is not there. How can I disable it?

Did you even have Hangouts in the first place?

I managed to disable it. You need to remove all Hangouts updates in Google Play, then reboot for Hangouts to go back to Talk, then Talk can be disabled in Settings -> Apps -> All.

You might want to add this fix as an answer and toggle it as the correct one.

I couldn't. I got a message saying you can't reply to your own question before 8 hours when you have under 10 rep.

The phone came with Google Talk, then Google forced the update to Google Hangouts.
You need to remove all Hangouts updates in Google Play, then reboot and Hangouts will disappear from the application list and Talk be back. Talk can then be disabled in Settings -> Apps -> All.

My phone (Samsung Note 3), came with Hangouts installed. The process was similar, however. Disabling the app automatically uninstalled the updates, reducing it to an old version of Hangouts.

On android kitkat: long click on the hangout app and drag it to app info. Click on turn off.
To enable the app again: go to home, press menu (bottom)/ select manage app /go to tab: turn off

Disable USB charging
For some reasons not related to the battery life, I need to disable the battery charging when a USB host is connected to my phone (a rooted Nexus 4). Taking a look around on the internet (link1, link2), it looks like I should modify a system file. I have found a series of interesting files located in /sys/class/power_supply/battery and /sys/class/power_supply/usb, that could be the right ones to be modified in order to achieve the usb charging disabling (e.g. /sys/class/power_supply/usb/present 0/1).
Has anyone tried something like that (control the usb charging via software and modify such system files)? Which is the best way to modify those system files? Should I use the adb shell or another tool?
I tried the "root explore" app in order to modify those files, however when I modified a file (after changing its permissions), it was automatically kept back to its original value.

While this may or may not contribute to the question, I'm curious as to why you want to disable USB charging.

What I have here is something more similar to an embedded system: a phone (USB ACCESSORY) and a piece of hardware (USB HOST), connected through USB. The phone battery supplies the attached hardware through a specific connection (Vdd). However, the USB HOST is supposed to supply (or charge) the phone through the VBUS line of the USB. What I want to avoid is a loop of charge between phone and attached hardware. Despite the attached hardware is the HOST, it is the Android phone that supplies the whole system. Hope my explanation was clear to you.

/sys is a virtual file system where the kernel exposes knobs and switches to alter and look up kernel configuration. You can't change the file permissions. I guess your nexus phone is unlocked and rooted. The charging circuit is probably based on a Maxim chip that may be configured. There are altered kernels available which allow overriding of the detection for power charging. The reverse should also be possible. You may need to patch and recompile the kernel though.

Franco Kernel for the nexus 4 allows fast charging, sources are available. maybe you can have a look at it and figure out how to switch it off: https://github.com/franciscofranco

Here's the driver: https://github.com/franciscofranco/mako/blob/nightlies-4.3-JWR/drivers/power/bq51051b_charger.c

duplicate of http://stackoverflow.com/questions/19316355/disable-usb-charging

I just tried and found that you need to modify a file:
sys/class/power_supply/usb/device/charge
its default content is '1' which means 'enable charging'
you need to set it to '0' to 'disable charging'
$ su

$ echo 0 > /sys/class/power_supply/usb/device/charge

I tested on Nexus 4 and it's working successfully.

I can confirm that echo 0 > /sys/class/power_supply/battery/charging_enabled works for me, on a Sony Z1 Compact with CM11. Thanks so much! :)

Please note that the /sys interface is virtual and does not persist reboots

adb shell dumpsys battery set ac 0; dumpsys battery set usb 0;

These commands are interesting, but they don't really affect charging! You could also do dumpsys battery set level 42 and the Android will think it's 42% charged, regardless of real battery state. Do dumpsys battery reset to return to normal.

Also, these fake changes freeze reported battery state and get recorded in battery statistics, which might mess them up and result in wrong "time remaining" predictions.

I'm not sure if it will work with your particular phone's charger, but often with cables that transfer both power and data, there are separate cords inside the cable for power, and data.
I'm not especially interested in tearing up my phone charger to confirm my idea, but you could try stripping part of the cable, identifying and cutting the power cords inside the cable, and wrapping it back up with electric tape.
There is likely a way easier means of doing this, but I'm not aware of it.

There are 4 pins in USB generally - 2 for 5v power and 2 for data.

If you cut Vbus and Ground it will also stop the data lines from working. USB cable connection is detected from the power (see the A-connector, the power pins are slightly longer so they will connect first).

I'm pretty sure it's not something you can change in software since the would phone charge when plugged into a computers USB port. You'd probably need to get your hands dirty and short a connection or two on the phone itself.

Yes it can also be done via software. Look at this app for rooted Nexus 4    stopCharge

You can use
adb shell dumpsys battery set usb 0;    // for disabling USB charging and
adb shell dumpsys battery set usb 1;    // for enabling USB charging

This is easy, but unfortunately it does not disable charging. It only makes it look like it is disabled.

I asked my colleague, who is an expert in battery driver. On our Nut Pro 2, whose kernel version is 4.4.21, the node for battery charging on/off is: /sys/class/power_supply/battery/input_suspend.

Same here on my Xiaomi Redmi K20 Pro with 4.14.

you can always use a shottky diode between pin 1 with the blocking side towards the accessory. that way the pin one gets a 5v signal so communication works, but there will be NO current flowing from the accesory to your phone. or if you want it the other way just place the diode in the different direction.

You can resolve the issue in hardware by modifying the pins on the micro-USB connector side. One obvious way is to not connect Pin#1 (VBUS) and the other way is to ground Pin#4 (ID) to pretend your host (PC) is an OTG device. If you do that, you have to disconnect Pin#1 (VBUS) otherwise one, if not both, of your devices will get burned.
As for the command line solution, you just have to find the right (device dependent) /sys/... files to play with. But as already mentioned, you need write access and root permissions to change these, and whatever you do it will only last until next reboot or change of USB peripheral.

The hardware solution suggested is incorrect. Almost every Android phone out there is a USB device that gets the power supply from USB hosts (e.g. laptops), thus working in Accessory mode. If you cut VBUS line the USB data communication stops working. I have tested this myself. I would say the same for the other way (ID pin) even though I did not test it.
You are right about the software solution, however not all Android phones have the /sys/... files necessary to do so (Nexus 4 yes, Nexus 5 no). Another solution should be the changing of the charging driver behaviour into the kernel.

Similar to the op, my Host who is connected via USB is also connected as a dummy battery. Can't simply use USB cable and no battery, android won't boot, nor does usb provide enough current.
You cannot fix this in software as Android will use Vbus during boot. Unless you also want to hack bootloader code.
The charging circuit needs to be modified to avoid usb charging vs battery voltage loop.
I confirmed on Galaxy S3 it requires 5V bus to enable data (d+ d-) it's part of USB standard.
OTG could solve the problem electrically but then the host client rules are not correct. Also this phone is able to OTG and charge (i use y-cable + gamepad)
Edit reference: https://forum.xda-developers.com/showthread.php?t=1863303

Will update once I figure out charging circuit changes

No, It is not possible on devices which are not yet rooted. It uses Settings.System with ADB_ENABLED, but ADB_ENABLED is a Secure-System-Setting which can not be changed by a application.
Yes, It can be done on rooted phone.
There is need to add an permission android.permission.WRITE_SECURE_SETTINGS.
I know you would be asking how do I do that:
Here is the link for a similiar app:https://play.google.com/store/apps/details?id=com.jim2&hl=en

What has ADB_ENABLED got to do with USB charging? Does the app you link allow to disable USB charging?

The app kinda allows you to disable usb charging after you alter write secure settings.

"Kinda"? What are the steps to follow?

Rotate reminder in camera
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.

This looks like something that would require a custom app. I'm not sure any camera app would implement something like this.

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!"

Thanks, that looks like a great app. I'll try it on the camera and report back.

Please do! You also might wish to take a look at other questions tagged "tasker" and the tasker tag-wiki on this site for ideas and links. Tasker is not an app you simply install and use, it's rather complex, but definitely worth the time to learn! I'm using it for several years now, and couldn't go without it anymore :)

What is the address for internal storage on browser?
If file:///sdcard/ is the access address for the SD card, then what is the address for internal storage on my HTC?

You probably won't be able to access much of your internal storage via the web browser. The URL you mentioned, file:///sdcard/, consists of two parts: the protocol (file://), and the path (/sdcard/). So basically, you just have to change the path accordingly. You can check with a file manager what the path to the desired destination is.

How to speed up switching pages in a PDF?
How can you speed up flipping between pages in a PDF (currently using ezPDF on a Nexus 7)?
What's the function that determines how fast a PDF can flip pages between? I thought it would be a function of PDF size, however, some smaller-sized PDFs flip between pages faster than some larger PDFs.
By understanding the "function", I hope to convert/refine my PDFs so I can flip between pages faster.
I love reading on my tablet (Nexus 7), but the main area it lacks in (when compared with physical books) is the ability to quickly flip back and forth between pages. It seems most pages need about 2-4 seconds to "set" before moving onto the next page.

That will very much depend on a) the size of the PDF file, and b) the complexity of the PDF structure. The latter includes whether and how many images there are, and if multiple fonts and different formatting is used. So basically, a small PDF with no images, no special fonts, and only few formattings will probably load much faster and be able to switch between pages much quicker than a huge PDF file with many images, fonts, and a lot of special formatting. But there's nothing Android-specific to this.

I use the Adobe app which is pretty slow even on a nexus 10. It's more bearable in continuous mode rather than page flipping, especially in portrait mode.

Variable amount of free space indicated in "Manage Apps"
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 df command from within any terminal app or via adb shell. It would list up all available file systems and their "free space" (df stands for "disk free"). But you would need to know what is what there. To give you an example from one of my tablets:
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

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 Android Folder Hiearchy to learn the important ones):

/system 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)
/data is your "internal storage"
*/sdcard* (differs between devices and Android versions) your internal or external SDCard (see next item)
*external* (may be external_sd, external_sdcard, ext_sd, ...) 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 /data (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 df output to make it better readable.

Thanks!  It's still not clear to me which is my internal storage available for apps.  I have /storage/sdcard0  13G 5G 7G 4096, and /data 1007M 873M 134M 4096.  There is no second sdcard listing, so should I be looking at /data?

As I wrote: /data is your internal storage (which is where your apps usually get installed to, and where they put their data). sdcard0 should be your internal SDCard. See also the link to Android Folder Hiearchy for more details.

Why the numbers don't sum up? "used+free != size" ?

They do sum up. It's just bad rounding: 2G - 505M = 1.495M, rounded down to 1G. So if you delete 6M, you should "gain" 1G – but just on the screen ;)

How do I recover my photos
i have Samsung galaxy gt-s7562 phone. i was wanting to reduce my phone memory. my photos and videos have all been cleared. i would like to know to recover them from my phone.

How did you clear them/reduce your phone memory? A factory reset?

Connect the external SD card to a PC and try a recovery software like Recuva(or any other recovery software for that matter) and see what it can recover.

Does Samsung Galaxy S II show any indication that sms sending is complete?
If I send an sms from Samsung Galaxy S II, it just shows a toast message saying Sending Message... which disappears in a few moments. Is it possible to set it to show some kind of confirmation that the sms sending is complete? Or ss this dependent on the telephone company?

Open the message thread in the Messages app and it should say "Sent" and the time at which it was sent.

In the default SMS app, it leaves a time stamp at the bottom of the message. e.g 2.16PM, Oct 13.
That is how it appears on my phone (S2 aswell)

Hey make sure you have checked your Delivery Report in the message settings option. I do have samsung galaxy s2 gt i9100 and i did the same to solve my query.

how do I open Delivery Report ?

Delivery report messages are just Notifications which you can say are just Flash messages which just disappear after you clear up your notification. And Delivery message just contains the text that the message is being Sent or Not. So theres no option to open it, but you can check through Notification Panel.

Is there a way to rollback to a stock rom without "unlocked" icon on XT910?
I'm looking forward to install new CM 10.1.3 to my Razr MAXX (XT910), but I see some bug reports about this version. I want to give it a try, but - is there a way to go back to the stock ROM if I don't like it? By "go back" I mean restoring it's original state, no "unlocked" icons.
Currently I have 982.124.14.XT910.Retail.en.FR (Android 4.1.2).

Please don't ask multiple question in one post, that makes it hard to answer. If you have multiple questions, ask them separately. That's how this site works, and this way it's also easier to keep track of them (and see what's answered and what not).

Modified. Now it's single question

The lock icon when you turn on your phone shows that the phone's bootloader is unlocked and doesn't show if it's rooted or not.
Just use the tool to you used to Root and unlock the bootloader to unroot and re-lock the bootloader it.
For info about the Razr XT910 have a look at this link

By flashing a ROM or rooting your Razr voids Motorola Warranty Terms.
  Even if you flash the same rom your Razr came with.  3. All the
  devices are divided by regions. This means you can only flash a stock
  ROM designated for your Razr region. Common Regions are: Latam (Latim
  America 'n Canada) - Europe - Asia - PSHAsia - ME - China - Korea -
  Japan(*

But, if I flash it back and no "unlocked" icon, how can they know it?

@relgames This device blows a QFuse when you root the device, meaning there is a permanent record of it being rooted, which can never be erased.

How to get your data(Photo's/Video's) from your broken phone?
Last week my Samsung Galaxy Fame broke, everything still works only the screen doesn't work anymore. It won't react if you touch it but it still works when you unlock it, so basically you can't do anything. Does anyone know how to restore my photo's to my PC, when I plug it into my computer it shows me that there aren't any files, but I have done it before and there should be files. Can anyone PLEASE HELP ME?!
THANKS A BUNCH

There are several related questions with answers you might want to check, e.g. Backup apps on SGS 2 with broken display? and I Need Help Getting Contacts from Broken Android!. Though they're not explicitly about photos/videos, they certainly hold useful hints for your situation.

The Galaxy Fame has a micro SD card and by default photos and videos are saved there. Just plugin the card to any PC via a reader and you should have the photos and videos.

Where can I get the kernel 3.4.0 with Source Code

C source code is compiled into executable code. There's very little need for C source code files to exist on Android devices.
If you want Linux kernel source you need to head over to Kernel.org.

Power problems with Droid Incredible 2
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. Usually the flashing seems to slow down and then stop (with the light off). There's no indication that it's charging.

There's no water damage, nor is there any physical damage to speak of. (Just some less-than-normal wear-and-tear.)
I've removed the battery and checked the contacts. They're nice, shiny metal. The battery is seated properly.
Have I got a battery that needs replacing? Does it just need to charge longer before turning on? (I am seeing the same issue with two different phone chargers, including one for my Galaxy Nexus that has no issues.)
Any insights?

The Incredible 2 has a defective charging port that does not typically last a long time. It is an extremely common issue with this phone. Chances are, this is what you are seeing.
Disclaimer: I have been using my current dinc2 for ~18 months and haven't had this issue yet, but I did see it on a used phone I attempted to buy. Anyway, my plan for if/when this does happen is:
Repair HTC Incredible 2 USB Charge Port
The part is supposed to be $12 and takes an hour to do. If you're not comfortable doing it yourself, I'd take it to a cell phone repair shop.

Well, my wife pays a stupid amount of money for a service plan, so I brought it in for repair.

Correctly adding movies to a Nexus 7
I recently got a Nexus 7 (this year's model), and I can't seem to be able to add movies to it properly. I dragged a bunch of directories, each containing a video file and a subs file to the Movies directory in /sdcard, but they aren't recognized properly by the default movie player (Google Play Movies). Instead, they show up in the gallery. The formats are either mp4 or mkv (x264 with ac3 or aac).
Where should the files go so they don't show up in the gallery and do show up in the movie player?

I'm not sure that the Play Movies app works like that. Play Books doesn't display local content, for example.

You may need to install an app to play these movies. As mentioned by eldarerathis, the Play Movies app doesn't play local content, only shows/films downloaded via Google Play.
MX Player, VLC and MoboPlayer are popular media playing apps. Personally I use MX Player.

How to reset my phone without deleting the game data?
I need to know please how can i reset my android 4.1.2 symphony xplorer without deleting it's game data

That would be a contradiction in terms: to be a "reset", it has to delete all your data. What you need to do is back up your game's data first, then do the factory reset, then reinstall the game, and finally restore the game's data from a backup.
This is easiest to do if your device is rooted: you can use a backup app such as Titanium Backup to backup and restore any app's data.
If you don't have root, then other apps can't access your game's data to back it up. If the game supports Google's automatic cloud backup, then that will work without you doing anything (though it's known to be buggy on some devices, when the manufacturer or carrier has customized/replaced the backup transport).
If the game doesn't support that, or you can't or won't use Google's backup for whatever reason, you can still back it up using adb, by following these instructions.

Many games generate files to save settings/records/step, so you can copy that files on the pc and put on the device after the reset

Nexus 4 Access Point details
Where can I get details about access point opened by my Nexus 4?
I need them to describe network in wpa_supplicant.conf on other device that will be using this network.
network={
    ssid="example"
    proto=RSN
    key_mgmt=WPA-EAP
    pairwise=CCMP TKIP
    group=CCMP TKIP
    eap=TLS
    identity="user@example.com"
    ca_cert="/etc/cert/ca.pem"
    client_cert="/etc/cert/user.pem"
    private_key="/etc/cert/user.prv"
    private_key_passwd="password"
    priority=1
}

Do you mean where is the wpa_supplicant.conf file?
If so, you will need root access as it is in:
/data/misc/wifi/wpa_supplicant.conf

No. I need info to put in wpa_supplicant.conf on my wifi 'client' device .

Alarm Volume On A Motorola Citrus
I'm using a Motorola Citrus.
Basically my alarm volume is low.  It is low in settings, but it is even lower, barely audible when I run a timer.
In settings I have the volume bar maxed out.
I also have the volume bar maxed out when I press the volume button on the upper right side of the phone
The phone is fully charged.
I'm using the sound of an alarm clock.
I'm new to Android and smart phones.
Any ideas on how I can make the alarm louder?
Thanks

If you go to Settings, then Sound, does it have multiple volume sliders? The Citrus should run software similar to my old Atrix 4G, and I remember it having a separate slider for Alarm volume (So you can have other volumes low, but your alarm can still be loud, etc). This is how modern devices handle it nowadays as well.

Under settings > sound and display settings I have: ringer volume, media volume.  Both volume bars are at the max.  In alarms there is a volume bar, also maxed. Under the timer, the thing I have the problem with, there is no volume control there

Hm... it's not normal Android behavior for the timer to ignore the alarm volume. Are you using the timer from the default Clock app, a Motorola bundle app, or a third-party app?

I'm using the alarm/timer app that came with the phone.  It is one app with two tabs, one for the alarm, one for the timer.

It seems like Motorola has shipped a weird alarm/timer app. I'd recommend looking in the Play Store for pretty much any well-rated alternative and see how it fares in comparison.

Enable USB Audio out on ASUS Slider SL101?
I have an ASUS slider SL101, and I want to know how I can enable USB audio out. Running Android 4.0.3. I broke the headphone port, so I need an alternative. Solutions greatly appreciated.

Depending on your device (does it support USB OTG) and your Kernel (does it support USB audio) you could probably use any USB class compliant USB interface. You also need to use software that can "talk" to the USB audio device.
One that worked for me was the Shure X2u with one XLR input and a stereo output. I used it to record high quality audio; it also plays back all my music when plugged in. The device I'm using does not have a SIM card so I don't know if this also works for phone calls.
Look at this Android Enthusiasts post for more info.
EDIT: at the moment it's quite hard to find out if those things work on a specific device. Manufacturers don't include the necessary data in their specifications. If your kernel does not support USB audio you can try others but most kernel threads on xda developers don't give information on USB audio so trying yourself is the best option.

I don't think the question is looking for recommendations of USB audio hardware. Rather, he wants to know how to get it working in Android: the part you skip over with "depending on your device".

Automatically have my frequently-used apps handy
I recently wiped and re-installed my phone. In so doing, I lost my home screen layout. In any event, my layout wasn't all that great.
What I'm looking for is an app/other method that would determine which apps I use most frequently and place them on my home screen automatically. I imagine this would need to be either a launcher or a widget. This way, I wouldn't have to spend time scrolling around for my most commonly-used apps.
Does such an app exist?

In year 2023, most of the answers are either dead or abandoned projects. Try Frequaw which is recent and works by placing a resizable widget in your launcher home screen. With a few tweaks to the settings, you can make it look almost seamlessly similar to the regular icons you add to the home screen.

determine which apps I use most frequently and place them on my home screen automatically.

There is Smart Widget.

This link is dead.

Cover is designed for this. It's a lock screen replacement app whose main feature is:

The right apps at the right time: whether you're at home, work or in your car, Cover learns which apps you use and puts them at your fingertips.

Basically, it has a column of app shortcuts along the left side of the lock screen, which it dynamically changes to the apps you use mot often depending on your location and the time of day. Although this isn't quite the auto-homescreen layout you may have been looking for specifically, Cover's idea is that you shouldn't even need to get to your homescreen; it lets you launch your most frequently used apps directly from the lock screen instead.

Microsoft's Arrow Launcher automatically arranges your apps based on your usage.

Hanger is another option I came across when looking for the exact same feature.
Main features from app description.

Auto-updating notification drawer shortcuts containing your most used    and important apps
Sort and display apps based on user specified weight factors
Pin apps to always display
Support for icon packs and custom icons
Optional second row of icons
Blacklist unwanted apps
Fully customizable! Change the number of shortcuts, icon color, icon    size, background and more.
Additional re-sizeable widget to launch apps
Re-sizeable widget to view app use statistics with color coded bar    graphs

Suppress "autoplay" when external USB drive connected
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. Now it no longer interferes with my own application that I am developing for my USB storage device. Not the ideal solution, but it works for now.

Deep sleeping apps will never run in the background.

Welcome to Android Enthusiasts Stack Exhange! Could you explain a little more about this post? Does it mean that putting an app on deep sleep may suppress the autoplay when the Android device is connected to the external USB storage? Or are you having an issue with deep sleeping apps?

Android 4.1 tablet Model M736 not recognizing keyboard when connected through 4 port usb hub
I am having a Belkin 4 port USB hub and an Android 4.1 tablet Model M736 made by Kocaso. I am trying to connect USB keyboard and a USB WiFi dongle to the hub and not able to see either of the devicces. Tried only the keyboard connected to the hub yet not able to recognize that a keyboard exists. But individually the devices work when connected directly to tablet. Could it be that the USB hub isnot able to support enough power when connected to the tablet.
Any suggestions

Connect a self powered USB hub and try again.
USB-OTG ports often provide little power that's suitable for one device only, but may already fail for power hungry devices like very fast USB thumb drives, wifi dongles or 2.5in USB hard disk enclosures. Your setup very probably draws too much.
You can use any 3rd party USB power bank if you need it on-the-go. Your hub may have a power input connector already. Finding the right cable might be an issue though. Here's some related info, someone asked this for the SGS i9000 which doesn't provide power at all: USB host mode not working on Samsung Galaxy S using CyanogenMod

Unable to connect to network after factory reset
Today I did a factory reset on my phone (Galaxy y GT-S5360T) to attempt to free up some space (it worked, thankfully) and now I can't seem to connect to any wifi network. I am currently running the stock ROM which is Android 2.3.6 Gingerbread and I am also rooted.
I also noticed after the reset the Google Play store had been replaced by the Android Market. I don't have anything against the Android Market, but I do prefer Google Play.
Does anyone know how to fix these problems?
Thanks in advance
Edit: When my phone tries to connect to a wifi network, the status reports that it is 'Obtaining IP Address" and it just ends there. Nothing else happens. I have heard in more than one place that I can create a static IP address and that will fix the problem but I have no idea how I can do this. It would be much appreciated if someone could point me towards a tutorial on how to do this, as I have no idea. I have also tried a factory reset again again and this still did not fix the problem.

Could you please [edit] your question and provide a few more details on your network problem: step by step, what are you doing and what is happening? What can you see in the WiFi menu (status of the APN you try to connect to)? Maybe you entered the wrong WiFi password? If it's not that trivial, can you connect your device to your computer and run adb logcat to check the system logs for errors? As for the "Market": This issue will resolve itself as soon as you got your network running, as it will auto-update to Google Play again.

This may be quite obvious, but what exactly is adb logcat and what does it entail?

First, try restrating the phone, this might fix most of the problems. If it doesn't work then continue with logcat.
Connect your phone to your PC using USB and run adb logcat in terminal(cmd window). (adb and fastboot can be obtained from this link.
After this follow the logcat guide here.

Use this app to pull the logs: https://play.google.com/store/apps/details?id=org.jtb.alogcat

Or https://play.google.com/store/apps/details?id=com.nolanlawson.logcat

@ce4 If he's got no network connection he cannot install from playstore (which is why I instead brought up adb logcat). Levi: Take a look at Is there a minimal installation of ADB? for a quick starter without unnecessary ballast. If you do not plan to develop apps, that minimal install is all you will need. Also check QtADB (linked there) for a graphical interface which might prove helpful to you.

Full ack, my bad. :-) He could download it from F-Droid, put it on a SDcard using his PC and side load it. Alternative Download links for logcat viewer apps: https://f-droid.org/repository/browse/?fdfilter=logcat

S3 battery not work after water damage
I dropped my S3 in water and the stock battery stopped working. I didn't know how to fix it (I tried drying it with a hair dryer but it did not work) so after comparing prices and discounts I bought a new replacement battery from MPJ and have used it for a month already.
It appears to work just as well as my stock battery. I don't know it's actual longevity but it works OK so far. Since I ordered from an official website, hopefully it's not a fake one...
I still want to fix the stock battery though, can anyone help me?

Using a hair dryer for that is, next to put it into the sun and after putting it into the microwave, one of the biggest mistakes for this task. There are plenty of better ways (including putting it in rice). As for "how to revive a dead battery", this isn't really an Android specific issue and thus not covered on this site, sorry.

Bowl of rice ftw will do the trick, but as @Izzy pointed out, classic! Someone here in Dublin lodged a complaint about Samsung S3 exploding when exposed to sun, Samsung execs panicked, flew over, to take it back to investigate, roped in help with fire brigade to investigate, transpires, that the guy actually microwaved the S3 to dry out after water exposure, when exposed in direct heat, shorted out the radio and "exploded"... got caught out in the end!!! There was a big thread on irish boards about it and had to publicly apologize for the uproar in the first! true story bro

Regarding the safety: Dispose of the dead battery. The li-ion part itself is sealed and probably unharmed, however there's also the charging/supervising circuit: That got soaked and due to the battery voltage, electrolytic corrosion set in and probably dissolved pcb paths already.

Basically, you can't. The charge/protection circuitry in the battery probably got damaged by the water, and you're done now.
Count yourself lucky that it was only a new battery that you needed and be happy.

Cannot mount SD card, with error "SD card safe to remove"
I have an HTC Desire S, which my cousin bought for me from China.
Android version: 4.0.4; HTC Sense version: 3.6; Software number: 1.0.0.S510e
The MicroSD card no longer works. Whenever I reinsert it, I get the message, after a few seconds, "SD card safe to remove". I've tried reformatting it and have run fsck on it.
I think the card used to mount read-only before, as it used to unmount whenever I took a picture; this started happening after the most recent update. I kept trying to take pictures and reinserting the card would fix it but it seems now it won't mount.
How can I fix the MicroSD card so it'll mount?

I'm assuming you mean MicroSD, not SD. Sounds like the card is broken.  You could try formatting it as ext3 or FAT and see if either work.  Also, see if it works on a PC (you can get a MicroSD/USB adapter for next to nothing).

Is it possible to use a MircoSD card with ext3 with android?

Actually I formatted it as ext3, and when I put it in the mobile, it said the filesystem was incompatible and reformatted it correctly. It works now!

Same thing happening to me.   After updating my Galaxy Grand to 4.2.2 i can no longer use the phone to format ANY MicroSD cards...   Very strange.   I need to format to Fat32 on PC and then it will work.  Even if i format to extFAT on PC the phone will reject it.
As an experiment, I deleted the partition on the MicroSD card with my PC. I then placed it into my phone. It prompted me that the card was unformated.  When i formatted it with the phone all i got was "SD Card safe to remove".
I removed the card from the phone and checked it with my PC. The phone did format the partition, but it was set as "Other" type..
Don't know what to make of this...

I had that problem with Dual USB flash, for PC and Mobile, it is 64gb so I couldn't format is with FAT32. I did the exFAT and NTFS but same thing happened. But then I found the solution on SanDisc website, it says that some mobile phones don't recognize exFAT, but FAT32 only.
They provided few third party softwares for FAT32 formating of 64gb:
HP USB Disk Format Tool , 2Tware Fat32Format , and miniAide Fat32 Formatter
I did it with second one and it works! My phone finally can recognize the USB flash.
I googled it few hours and except this solution didn't find absolutely nothing that works...

How do I install, update, and remove apps for multiple devices in the Google Play online store?
I've got several Android devices. I like to use the online Play store to manage installs because it's much faster than doing so through each device. However, I do not see a way to determine which apps are installed on which device without clicking through the following links, once per app:

Apps → My Apps → [specific app] → Installed → Choose a Device

How do I quickly do the following, without going through the process above?

Review per device installations.
Select apps for installation, update, or removal, per device.

I used to use the web interface to update apps on all my devices then Google updated the Play store and I haven't figured a way to do this since. It seems like they really want you to do updates via the device instead of the web.

Unfortunately Google play Web app doesn't allow you to the following things:

Update your current apps (It can only be done from your devices)
See a list of apps install in a specific devices (It only tallies all of the apps you ever downloaded into one list)
Remove any devices which were previously added to your Google account

Hopefully we can raise awareness through this question so that Google finds that enough people will like a lot more functionality from the web app. It is sometimes very functional specially if you work in a computer all day.

Do not see synchronized "My calendar" on Android 4.1.2 phone in Google Calendar web interface
I have added new event in Gapps "Calendar" application (Google Calendar) on my Android 4.1.2 phone.  This event got added to "My calendar" calendar (and I cannot change this which calendar this event belongs to after creation).
Though "My calendar" is selected both in Calendars to display and Calendars to sync it is not visible in Google Calendar web interface: https://www.google.com/calendar/
Where this "My calendar" is sync'ed to?  Can I add it to be visible from web interface (does it have and URL)?  How can I copy or move event to my main personal Google Calendar calendar ("Jakub Narebski <...@gmail.com>")?

I see that I should have added the first event by using Menu > New event rather than clicking on timeline.  How can I copy it to other calendar?

I have exactly the same problem, did you ever find a solution to this?

How do I get this iTunes song on an Android device?
I want to buy this song, but it appears it's only offered on iTunes.  I have no idea if it's DRM protected or not, I just want it on my Moto X.

What are the most direct and straigtforward steps to determine if I can put this song on my device, and how I can do it?

I would like to purchase the song directly from my phone, but I have both a PC and a Mac

In recent years, Apple has sold songs on iTunes without DRM. You can convert them to other formats pretty easily, then just drop it onto your Moto X using a USB cable (Or even just email it to yourself, then download it using your email app on the phone).
Music stored on the phone should automatically be added to your "On Device" library in the Play Music app. I would recommend making sure you save it somewhere standard like /sdcard/Music/ for your convenience.

I don't like iTunes much, but I keep it around because I still have an iPod floating about. I have the Google Play Music uploader synced to iTunes. So, were I to buy a DRM-free song in iTunes (and it, of course, is locally downloaded) it will automatically be converted (if necessary) and added to my Google Play Music library and I can pin it to my device for offline enjoyment.
The only time this doesn't work flawlessly is when the source song has DRM on it. If I recall, though, everything coming out of iTunes these days lacks DRM. (At least, music is that way.)

My display doesn't work but the touch-screen does
My display doesn't work, but the touch-screen portion still works.
Will I need a new digitizer or will just a screen replacement do?

How do you know that the touch-screen still works? Have you connected the device to a TV or something to know that touches are still being detected? I'm just curious (and it may help determine if you need to replace one or more parts).

More to the point, though: most devices nowadays have the digitizer, lcd, and glass all fused into a single piece. Thus, it is impractical to try replacing only one part.

@StephenSchrauger I know because I can still unlock it (since I've memorized where it was) and hear the feedback. Same with moving around icons etc. Was just asking because the digitizers can get pricey. Thanks for the info!

How to upgrade or remove and install a new Android OS in Ubislate 7C+ Tablet
I want to install a new Android version in my Ubislate 7C+ EDGE Tablet. It has wi-fi, 3G Network support, 10 point touch screen, inbuilt SIM card slot, 4Gb internal memory and 512Mb of RAM, and a 7in screen with 800x600 resolution support.
I don't have even the basic idea of how to start (I'm a novice), so please  start from the start. Please explain complete process step-by-step, and don't skip even the tiniest of details (connections, OS details, architecture, etc.), keywords, etc...
I am also unable to find any proper link to download android 4.2 for tablets, please refer sites or links.

Welcome to the site! I'm not quite sure what you're asking for here. "Install a new Android OS" is a pretty ambiguous term. Are you looking for the factory Android image from the manufacturer? Are you looking for a Pure "Google Android Experience"? Are you looking for a Custom ROM?

Also, whatever you're looking for, it's not going to be as simple as downloading "Android 4.2 for tablets". There is a lot of device-specific code that is proprietary and cannot be included in the Android source (drivers and the like). You'll need a build that's specifically designed for your device, and it's possible that no such build exists if the device lacks support from the manufacturer and third-parties.

dotVezz- Thanks but I don't care whether the Image is from Google or a Custom ROM. Factory image is not available as per my knowledge due to some patents, and a slow customer care & support.And yes i am looking for a pure "Google Android Experience".

eldarerathis- My device is not included in the list for rooting guides...

I found a ROM for my device at the link-http://forum.xda-developers.com/showpost.php?p=40693126. But I cant understand the steps of action. Please help...

The above link takes me to a site to download ROM for 7C+ , not 7C+ EDGE.. might work still..

No custom ROM or anything. I have not played much with the phone in anyway.

Issue in GSM for Straight Talk and MMS.
I just purchased a GSM unlocked Android phone.
And called into Straight Talk to get the new APN setting.
But, the settings they gave me would not allow me to receive MMS.
The web and testing works fine.
Please help me on which settings to use?
NOTE:
Someone told me to re-configure my phone, will this help?

What service is your straight talk under? Your APN settings have to match the network that you join.
Try this form:
http://www.straighttalk.com/wps/portal/home/support/apn/!ut/p/b1/04_SjzQztzA3MDQ0N9KP0I_KSyzLTE8syczPS8wB8aPM4l0MvHyNAx09jIKM3FwNPN3cjAx8PYMM3N0N9HOjHBUBlTx7Ew!!/

Try with these settings: http://apn.gishan.net/settings/os_12_11_android_4.4kitkat_internet_and_mms_settings_for_straight_talk.php
Should work. Sorry. Site does not allow me to copy the settings.
How ever if you cannot receive MMS that should be a data problem. Please check you can access data properly. MMS APN is only for sending MMS. Do you receive MMS notification at least?

When that link stops working, this answer has no value. Please don't make future readers go to some other site to get the information they need.

You have to remount read-only partitions with a permission of read and write first.
# mount -o rw,remount /
# mount -o rw,remount /system

Now, you can do anything.

Device version-baseband is 'D720SPRXXX'.
Update requires 'D720SPRKC9' or 'D720SPRKD8' or 'D720SPRKE5' or 'D720SPRKH1'.

Searching "D720SPRXXX" on Google gets exactly zero hits. How did my baseband version get like that, and how do I change it to make Google's update happy?
It's worth noting that the device still boots into CyanogenMod without issues, and can be reflashed with a new version of CyanogenMod; I just can't install Google's factory image.

what I found was that flash_all.sh actually updates the baseband version with the radio image. but rebooting from fastboot to fastboot again does not show the update in the baseband version.
so manually reboot the phone to normal boot, and try one more time going to fastboot and do the update.

I managed to get the phone fixed, but I still don't know what actually caused the problem. Here's what I did:
I was using the "sojus-jro03r" image. I assume the same will work with any other. Once I unzipped the archive, there's a file called image-sojus-jro03r.zip inside that contains the OS image. Inside that archive is a file called android-info.txt.
That text file has a couple lines in it, the last of which starts with require version-baseband. By adding |D720SPRXXX to the end, I was able to trick the update into accepting my device. I updated that text file in the .zip file, ran flash-all.sh again, and everything worked as it should!
My phone's working as I want it now, but I'd still like to know how in the world this happened in the first place. I'll leave this question open a while longer, and if anyone can explain what would cause a problem like this, I'll accept that answer.

How can I send all calls to voicemail during "busy" calendar events?
Basically I'd like to have something that auto sends calls to voicemail when I'm "busy", and possibly as a bonus, send a reply text as well.
Is there any solution for this?

See also: How to enable silent mode during calendar events?

There are a few apps that can do this for you, or at least some of these things. One I saw on Lifehacker yesterday is Agent.

Agent is a combination automation tool and personal assistant that will silence your phone during meetings, remember where you parked, auto-respond to texts and phone calls while you're driving, and more, all so you don't have to.

Unable to mount SD card to Ubuntu 12.04 LTS
Can anybody explain how to mount ICS/Jellybean on Ubuntu 12.04 without rooting? When I connect my phone, it goes into charging mode, however, I can't mount the phone memory/sdcard to my Ubuntu system. On Windows virtual machine, it works just fine! Please help!

If it's using MTP, then there are a number of questions you may want to look at. http://android.stackexchange.com/questions/15877/better-way-to-connect-galaxy-nexus-ics-to-linux, http://android.stackexchange.com/questions/34162/what-are-my-options-for-connecting-my-android-to-ubuntu, http://android.stackexchange.com/questions/52072/how-do-i-make-my-linux-pc-mount-my-android-4-2-2-phone-using-mtp

Adjusting between Group & Single text messaging on Galaxy S4
I recently got the Samsung S4 on AT&T. I used to have the Motorola Razr M on Verizon. On my Razr M I was able to switch between group text and individual text messages at the time of sending. So if my main setting on my Motorola was to send individual text messages, I was still able to receive group messages as a group and the default was to respond individually, but I had the option to respond as a group also. Does that make sense?
Example 1:  I could send a picture to 10 people but those 10 people would think they were the only people who got the text message.
Example 2:  If I receive a group text message that someone wanted 10 of us to get and we all need to be able to respond for a work project we were able to with the Motorola.  With my Samsung if I disable MMS then I am only able to see who sent me the message but not everyone who was included so I am not able to respond all.
Example 3:  If I needed to send a group text message and have it sent as a group I was able to adjust at the time of sending by clicking on group instead of individual and all the people who received the message would see who was included on the text.  Even if the main text message default setting was individual.

In the stock messaging app: settings->multimedia message (mms) settings->Group messaging.
When this is checked, it will send a single MMS message to multiple people (all within the group), like in examples 2/3.
When it is unchecked, it will send a message to each person in the group individually, like in example 1.

All incoming group messages will come in as a group message regardless of this setting.  This setting simple controls how your messages are sent to a group.  As far as I know, however, you are not able to do this on a per message basis.
