LED not turning off even after there are no unread WhatsApp messages
I have this random problem with WhatsApp: the green light that blinks when there are unread messages don't turn off even after I go and read them. It doesn't even help if I delete all the messages. The only thing that helps is restarting the phone.
I have a Nexus 5.

Are you using latest Whats.app version?

Yup. I am on the latest.

Is it possible to choose color? Can you try choosing white or some other color to test if that works?

The color doesn't change once this issue happens. Even turning off LED notifications from settings doesn't affect it. I even terminated the WhatsApp process; didnt help. Restarting the phone was the only way out.

Do you use stock ROM,GravityBox? This might not be caused by whats.app.

I am on stock ROM. I am not using any third party app to modify the LED. Although, I do have DashClock installed.

In whatsapp notification setting try  setting it to none and check if the problem persist then it may be due to some other problem

For what its worth, the issue stopped occurring after I changed the Whatsapp notification light color to white. I think it might have something to do with the fact that Whatsapp and Hangouts both had the notification light color set to green. If this happens to you try providing a distinct notification light color to all the apps.

This very same thing is happening to me on my LG G4 (which I just bought recently second hand).  It's rather annoying, definitely due to WhatsApp because whatever I change the colour to, that's colour which keeps flashing!  I'll try the white light, but tired changing a couple of times now and no luck.  Do you have any other advise?

Why are Android Apps not as polished as iOS?
When I owned a iPhone, all the software seemed to be very polished(Visually). For example, the process to getting to menu's shorter etc. I own an s4 and the apps and the software does not seem to be as polished as iOS?
Both platforms are being developed by very intelligent programmers and creative people, so why is it that Android is not as polished?

what is polished?? you have windows transition and animation scale

They don't seeem to be as visually appealing

You can set the windows animation and transition animation scale

How can i do this? Can you point me in the right direction?

@sameer That's a development option, to make it easier for app developers to test animations in their own apps. It's not intended for general use, and might make some apps behave oddly.

@DanHulme I know it is a developer option but will it cause any effect on app? I thought it is like aero animation scale in windows

@sameer As an example, say an app runs one animation and another when the first is supposed to finish. Scaling the animation length makes the first one finish late, and the second might start while the first is still running, causing a conflict. The more complex the animations are, the more likely that changing something will make them go wrong.

One man's polish is another man's unnecessary glitz.

I mean, I can see why Apple users tend to stick to their devices. Because they are in a way a lot simpler to use and almost apps "look better on the eyes". @Dan Hulme explained why that is probably the case... conventions, open source, hobbiest etc... But if Android really wants to kill the competition surely this is one area where it can improve? This is just my own opinion guys :)

This question was asked to find out some information and get user opinions.

It really comes down to customer expectations. With iOS, Apple uses the built-in apps to set an expectation that apps will be "blingy", with all kinds of eye-catching animations. If you look at Android's built-in apps, they're not so eye-catching: animations are subtle (usually simple fades or fly-ins), they have a much cleaner, drier look, and they have very similar, familiar conventions about menus and transitions. This has set the expectation amongst Android users that app-specific bling is much less important than respecting the conventions of the platform and integrating well with other apps.
At the same time, the app ecosystem and the consumer market are very different on Android. Apple has a very large barrier to entry: you can't realistically develop iOS apps without buying a Mac, and a physical device, and paying a subscription to Apple. This means that for the most part, hobbyists and small developers are excluded from this market.
In contrast, the Android development tools are freely available and support Windows, Mac, and Linux; there's no subscription to be a developer; you can get onto Google Play for a small, one-off fee, or distribute apps outside of Google Play (on other app stores or independently).
For this reason, while Android still has all the big-name developers you find writing iOS apps, there's also a much larger number of small developers and hobbyists. Hobbyists are much less likely to add bling or visual design features to their apps, because they just want to develop something useful. There are a lot of incredibly well-written and useful hobbyist and open-source apps, but they're much less likely to add visual design varnish to them. As well as bringing down the average amount of varnish for an app, this also feeds back into the consumer expectation that Android apps don't need so much bling.

no alert tone when receiving a message
I have Samsung galaxy s duos 2 GT-S7582. my problem is that, everytime I receive a txt message, I don't hear any alert. ive already checked all the notification settings and all of it were turned on..

Goto message app->click menu->settings->set notification tone

Do you hear ringing when you receive a call?
If you hear nothing at all you might want to check your headphone jack, it has a little switch inside that is used for the phone to detect whether headphones are plugged in or not. These switches tend to get stuck from time to time causing the phone -wrongfully- to detect headphones are plugged in, and sending the audio to the jack instead of the built-in speaker.
Only try the below in case you hear no audio at all from your phone's speaker!
First I would try by blowing some air (either with your mouth or lightly pressurised air, like from those keyboard-cleaning spray cans). If this doesn't work you can try loosening the switch by poking around in the headphone jack with a toothpick or something, just be carefull not to bend any of the contacts or something.

thank you for your help.. its ok now.. ive reset the phone.. haha!

Eclipse(and adb.exe from sdk) doesn't detect my beaglebone black as running android device
I need some help for problem. I'm using Beaglebone Black and Android (JellyBean 4.2.2) with 3.8 kernel. BBB connected to window7 through USB which comes with BBB. When I boot the android on micro SD card, it works fine(I'm using 4DCAPE LCD screen) but I cannot find it as running android device. I turn on the USB debug mode.
Thanks.

I am assuming that you are using the Andrew Henderson's 3.8 Kernel + Android JB configuration. As I understand the adb as it is intend is not functional in this configuration. Nikolay Elenkov in is blog has the following work around. Following is a direct word to word copy from the his blog
Configure FunctionFS support in the kernel
(CONFIG_USB_FUNCTIONFS=y):

Device Drivers -> USB Support ->
     USB Gadget Support -> USB Gadget Driver -> Function Filesystem

Modify the boot parameters in uEnv.txt to set the vendor and product IDs, as well as the device serial number
g_ffs.idVendor=0x18d1 g_ffs.idProduct=0x4e26 g_ffs.iSerialNumber=
Setup the FunctionFS directory and mount it in your init.am335xevm.usb.rc file:
mkdir /dev/usb-ffs 0770 shell shell
mkdir /dev/usb-ffs/adb 0770 shell shell
mount functionfs adb /dev/usb-ffs/adb uid=2000,gid=2000

on fs
Delete all lines referencing /sys/class/android_usb/android0/*. (Those nodes are created by the native Android gadget driver and are not available when using FunctionFS.)
Please review this blog for detail infomation

I need to control samsung Duos s 2 phone like my earlier nokia phone using pc suite
I need to control samsung Duos s 2(GT 7582) phone with my PC like I am having now with nokia phone using Nokia pc suite

Thanks. But, the primary question is controlling the phone after connecting to PC. Wanted to call , SMS from PC using phone w/o really touching the phone. Hope I am clear..

I use AirDroid. It works pretty well for most things like sending messages, transferring files and calling, and you don't have to plug your device into your PC.

Enable bootloader screen for Lenovo Vibe Z
I pressed and held volume up key for sometime and my Lenovo Vibe Z is seems to be bricked (not charging or switching on). I would like to get into to the boot-loader screen to factory reset the device.
Two things:

Please help me with the key combinations required to get into boot-loader.
Or ways to unlock the boot-loader in Lenovo Vibe Z.

Volume up and Power key?

not happening..I don't understand..it should charge at-least..

How did you manage to brick it? Or is it simply not charging?

While I was on call I pressed and held volume up button..and that was it. Its bricked or not I have no clue.

Hold Volume Down and then hold Power

I would be more concerned with 'not charging' than anything else. Is the cable or the plug damaged? It may be a hard brick, i.e. damaged hardawre. Start with the plug and cable for the charger, try another socket and your PC to charge. Then try another cable / charger. Failing that, try another battery if you can get a hold of one, and so on until we can isolate where the problem is.

Done. Problem was with the charger, was using Samsung charger.
But I still have no clue why it got off by holding volume up key and I am sure that charging was above 20%, it should have resurrected to life when I pressed power button.
And while I am at it, this phone awesome except its antenna. Voice breaks with the jerks on road.

1) Go to your phone's Settings > Storage
2) Unmount SD Card (your external SD card)
3) Download/install from the app(s) from the Store again
4) Go back to Settings > Storage - then Mount your SD card again (or reboot)
Or you can try this
1)Insert the sd card in you windows pc
2)You will find a folder named android_secure in it you will find the file named smdl2tmp1.asec delete it
(Make sure in pc folder options, the show hidden files are enabled and the hide protected operating system files is unchecked)
Source: XDA

Sounds like it's trying to install direct to your SD card.

Go to settings>storage>unmount SD card
Install the app
mount SD card again

Better You Format and try again , still prob download your app from your Pc ,search playstore and download from it .If you havent set your mobile number ,set it .
Or
Download apks from http://apps.evozi.com/apk-downloader/ in your pc and copy and move it to your Mobile phone

When a thing like that happens you need to install the driver "Broadcom Usb to Serial" and you need to use SPFlash tool with the correct scatter file for your model .
Scatter file includes the addresses for all the partitions in the phone memory , like boot , bootloader , recover , data , system ,etc ..
The Scatter file have the Hex addresses of each partition and its size .
Here you can find the driver :
(Note: This driver is for windows XP 32bit , it does ot work in 7 or later , create a VM for this )
http://www.mediafire.com/file/phbd8epz92u6dw2/Broadcom_smartphone_USB_Driver.zip
The firmware you can find it here , download the stock rom Eglish:
https://github.com/peterpt/Alcatel_V860_smart_2/tree/master/Roms
SPflash tool ca n be downloaded here :
https://spflashtool.com/
Now the most important thing (Scatter file) i am unable to get it for you because i am also looking for it :) .
Let me know if you find it .
The manual in how to do all the process can be found here :
https://www.gogorapid.com/flash-stock-rom-alcatel-v860/

Mediafire links aren't useful because they expire after a short time. Do you have a link to an official, trustworthy download for this file?

Broken screen and touch on Acer CloudMobile S500, how to control?
My Acer CloudMobile S500 has a broken screen and the touch don't work anymore. After that happened, I connect it to my computer with USB, and happily USB debugging was turned on so I could get all my stuff from my phone.
But my question is, how can I control my phone from my computer? My phone wasn't rooted so I really don't know how to do that without the touchscreen.
I know there are a lot of the same questions like this, but all the answers didn't help me.

If previous answers didn't help you, you need to say why: what did you try, and what happened? That's the only way you'll get answers that are more helpful to you.

Related: Control Android with broken screen from PC

Use a USB-OTG cable, then you can connect a mouse to the phone and you'll get a cursor on-screen. You can also connect the OTG cable to a USB hub, then you can connect both a mouse and keyboard. You could also connect a wired mouse long enough to pair a Bluetooth mouse/keyboard to the phone.

There are several possible scenarios I can think of:

Send inputs through ADB
If only part of the screen's touch digitizer is damaged, you can use the native Assistant Menu accessibility funtion to get a mouse pointer on-screen, trackpad style.
Use an adapter and plug a mouse into it, assuming they are compatible.
If your screen has multiple digitizers, e.g., Samsungs Note series, when one is damaged it doesn't necessarily mean the other is too; in my case, I had a phone where half the screen no longer reads finger touches, but the stylus still worked full-screen.

There is no OTG on that device, and you would need ADB authorized. the only thing left is replacing the digitizer.
Actually quite easy on that model.
Pending you have ADB:
the command is

adb shell input tap x y

or

adb shell input text

Practice on a working phone, I think its pixel based - vertical orientation.
so look up your pixels, measure it out - mark up some packing tape or something (make a rough grid) and then type tapes to interact

Tablet touchscreen too sensitive
My tablet (Asus TF300T) has been starting to show sensitivity issues. It repeatedly shows touch moves that aren't there, such as these:  (this screenshot was taken using the debugging option for showing touch input)
It started out with an occasional movement that was already annoying, but it went worse: these dozen concurrent presses are persisting, moving and raising in amount: The tablet is uncontrollable now. Is there a way to turn down the sensitivity so that these fake fingers don't show up or to turn the touchscreen off completely?
Although the tablet itself isn't accessible anymore, USB debugging is turned on, the tablet is not rooted. Standard Rom, updated to 4.2.

No, there's no setting for the sensitivity. The touchscreen controller already filters the input it gets from the screen itself, so probably you wouldn't be able to filter out the faulty touches without also filtering out real touches.
What you describe sounds like a hardware problem. I'd recommend giving the screen a wipe with a damp, soapy cloth, then a rinse with a damp cloth, then drying it. It might or might not improve matters, but it's worth a try. If that doesn't help, you probably need to replace the screen completely.

I tried cleaning it, I ended up sending it to the manufacturer for a repair, because it was still under warranty.

I had the same issue, and I tried to replace the screen and digitizer and it didn't work at all (spend money for nothing).
After a few weeks, I was trying again. I touched the flex of the digitizer and it got crazy, like your picture. Then I tried to took off the board which is connected to this. When I put it again, the screen was fixed. It's been OK for many days now.
So check the board and screw it property. It is a little board where the MiniSD card reader and the reset button, also has 2 flex, one of the digitizer and the other is grey and connected to the main board.

App to lock phone with PIN
Device: Samsung Galaxy SGH-S730G
Android: 4.0.4
When my phone is on me, I don't want to use a PIN, password, or pattern on my lock screen. I just want to swipe to unlock quickly. However, if I leave my phone somewhere, I'd like to lock it with a PIN or password. Is there an app that will let me lock my phone with some kind of security, even though my normal settings just use swipe-to-unlock?

possible duplicate of App/shortcut to quickly change screen lock type?

Actually, yes, it's the same question, but from 3 years ago, and all the answers are for Android 2.* Looking for some more up to date information.

ah, I didn't notice that, sorry. To be honest though, Tasker is probably your best bet as it can be customised to how you want it. There may be other newer apps though.

I'd vote to keep this question open, if only for more updated answers to the one recommended duplicate.

I second the "keep open", for another reason: it's not really a duplicate, rather a "close relative". Here the question is not about a location, but about whether the device is in reach of its owner. So possible solutions could include things like "bluetooth proximity" (requiring a second device "attached" to the owner), or even an "NFC ring" on your finger to unlock the device.

How to disable calls but still receive texts
Is it possible through a setting or an app to receive only text messages and not phone calls?
Specifically I have an Samsung galaxy s3

Not tested: you could disable the Dialer, go to Settings > Applications > Phone (or possibly 'dialer') and disable. Not a great work around. You could route it to your Google Voice mail if you have that set up. You could use a blacklist app: https://play.google.com/store/apps/details?id=com.sriseshaa.android.myblocker or https://play.google.com/store/apps/details?id=com.incorporateapps.callblockerlite and see if you can block only calls... Let me know if anything suits or works and I'll expand a fuller answer.

Not sure about the Galaxy S3, but my S5 has the option to disable just the calls. Open the Dialer → Settings → Call → Call → Rejection → Auto rejection mode →All incoming calls.

Use call forwarding. Forward to a number which is not in the network.

Shell script to reboot into recovery and install zip
Okay, without getting too deep into details, I'm looking to automate the installation of a flashable zip (must be flashed from recovery).  For now, I can use the command "reboot recovery" in a shell script to bring me into TWRP, but I'm not sure how to tell TWRP to install something automatically.
I know this is possible because Cyanogenmod does this exact thing with their ROM update utility.  Once a ROM update is downloaded, you click "Reboot and Install" from within CM, the phone reboots into TWRP, the installation of the flashable zip begins, and after it completes the phone reboots again back into CM.
I don't know if I can just append the file's path onto the "reboot" command with a particular switch?  I haven't been able to find documentation on the available options.  I was also thinking maybe TWRP looks for an update.zip file upon launching?
Does anyone know how to do this?

I ended up looking at Cyanongenmod's source code and figured out how they did it.
Here is my working .sh script:
echo 'boot-recovery ' > /cache/recovery/command
echo '--update_package=/sdcard/update.zip' >> /cache/recovery/command
reboot recovery

Update:
with android JellyBean [4.1] and later versions, the sdcard data is located now at /sdcard/0, So the second command must be:
echo '--update_package=/sdcard/0/update.zip' >> /cache/recovery/command

I got this error: E:cannot mount /sdcard (No such file or directory) ---- E:Can't mount /sdcard/0/update.zip ----- Installation aborted.

Your device may not use that symlink "/sdcard/" then.  Try "/mnt/sdcard/update.zip" instead.  All storage devices should show up somewhere in "/mnt/", use a root file manager or terminal emulator to list all the available options.

I can access mnt/sdcard in terminal, but when I got this error in recovery mode: Finding update package......
E:unknown volume for path [/mnt/sdcard/update.zip] ......
Can't mount /mnt/sdcard/update.zip

One thing you can try next is browsing your root directory structure directly from recovery.  In both TWRP and ClockworkMod, the "Install from Zip" feature can act as a directory-browser.  Navigate through your root directories (obviously not installing any zips here) and see if you come across any sub-directories which lead to your desired storage location.  On my device, I was unable to find any alternate paths; "/sdcard" is my only option.
If you're unable to find your sdcard, I'd say just forget about flashing from that location. Copy the zip you're flashing to "/cache" and call it a day.

How to upgrade to 4.4 from 4.3 (Samsung Galaxy S4, already rooted)
So for a while I've been getting the update message, and not bothered and now it's getting annoying.
It is rooted to 4.3 currently, but when I click install it just takes me to TWRP (I think that's what is called) and I am not sure where to go from here, if I am even on the right track.
Thanks.

You didn't mention if you're on Stock ROM or Custom ROM. But you mention TWRP, so you're probably using a custom recovery (though not necessarily on a custom ROM). What I would try to do is to push Stock Recovery back into your phone, and try the OTA update again.
If that doesn't work, you can download the Stock 4.4 ROM from sammobile, and flash it using Odin. Take note that this will wipe your data.

I think it's a custom ROM, since on Wanam Xposed I get "Your ROM doesn't seem to be a Samsung ROM". So I guess the Stock 4.4 ROM from sammobile would be the way to go.

@Chris Yes, that would be it. Wipe phone before flashing stock ROM using Odin.

Or you could install a custom KK ROM instead if you don't want to go stock. There are some great Tochwiz Roms with Xposed installed, and I'm currently using the Google Edition ROM with Android Runtime (ART) enabled and man is it fast!! It's a big difference from Touchwiz! Just an alternative to stock.  Here is the full guide to unroot/restore stock ROMs: http://forum.xda-developers.com/showthread.php?t=2265477

Since you talk about updates that take you to TWRP, I assume you're talking about Stock ROM with a custom recovery. If you have a stock ROM, any updates are made through recovery. However, the update is programmed to be installed through the STOCK RECOVERY
Therefore, you won't be able to install the update. If you already have a rooted device with custom recovery, why don't you just install a custom ROM from XDA?
Not only will you get updated, you can say goodbye to TouchWiz (yay!)

Where to place .mp4 files in Nexus 7?
I have connected my Nexus 7 to my Macbook, and I am using the app Android File Transfer.
I want to place an .mp4 movie, but I am not sure where to place it. I have tried placing it in the Movies folder, but then when I go into my Nexus and go to Play Movies and TV, is not there.
Where am I supposed to place that file, so that I can open it from Nexus?

Are you talking about Google Play Movies & TV? I think this is only for rented / purchased movies in Google Play.
To play an MP4 file on your device, try an app like MX Player.

With an app like MX Player, or VLC, you can place your video file anywhere in the device and the app can open it. But it would be easier to keep all your video files in one folder such as Videos or Movies so that apps which does indexing can index all the videos in that folder automatically for easy browsing.

I have an HTC desire C and want to turn off Google voice typing
The keyboard is so small that I keep hitting the voice typing microphone icon but I don't want to use that feature ever. It's too slow and lags.
So, I want to turn it off completely. Under settings>language & keyboard> keyboard & input methods, there is no option to turn it off.
This thread: How to turn on/off voice typing is similar but addresses another model that does appear to have an on/off feature or box to check to enable or disable. HTC Desire C does not seem to.
So how can I turn it off or disable it?

Disable both Google Voice Typing (in the keyboard menu) as well as Voice Input key (under Languages).

CamScanner - how to get image instead of PDF
I run CamScanner 3.2. In earlier versions, it used to save the image as a JPG (or PNG, don't remember), but with the latest version, it always seems to save as a PDF. I couldn't find any setting to make CamScanner save the scanned thing as a image file. Is there one?

If you view a document, it will be exported as a PDF. Individual pages however are exported as a JPG.
So you must select the document, then select the page, then select "Share". If you don't see the "OCR Recognize" button to the left of "Share", you aren't looking at the individual page.

Removing mobogenie
I saw the Mobogenie in my installed apps list. Uninstalled and it is coming back from somewhere when I connect to internet. I think this is a genuine app, but a bit concerned about the intrusive nature. Also it is posting notifications once it comes back. Does anyone had similar experience?  Is there a way to remove Mobogenie permanently?

Mobogenie has been updated so users can decide either if they want to install our software or not. This solves the issue of consider Mobogenie as a spam software and focus in our content. Glad to have a further discussion to solve any remaining doubt.

Thanks for the details, Santiago! But could you please [edit] your post and include why the app re-installs itself when the user explicitly uninstalled it (as the OP reports) – and better yet, how to avoid that?

So you work for/at/with developers of mobogenie? Force installations, great.

even if that is an "option" it still is underhanded and sneaky. Mobogenie isnt the only one that practices "strange and weird" marketing practices. Forced downloads aren't done by choice, but the installation is? No good.

Make sure you have uninstalled mobo genine market.
Go to App, and swipe until you see "All" you will see 2 Downloads icon there.
The Downloads with no size is the legit one. Keep it, if you long press and select App info you will see that it's something related to your firmware.
The 2nd Downloads icon is the culprit, with a version of 2.02xx. Long press it, select App info then uninstall.

When I go to apps list, I can see 2 Icons. One with name Mobogenie, other with name Mobomarket. I tried removing both. But unfortunately this comes back when I connect to internet again.

Switch to safe mode. Safe mode can be activated by pressing and holding volume down button during boot up process. And then you can easily uninstall the app

That will put certain devices in download mode. You should specify what other ways there are to accomplish this. As the answer stands it should be a comment.

How can I delete a group in Viber?
I made a group in Viber. I wanna get out all of members from this group. How can I do that?

Open Viber.
Go to the group conversation screen.
Swipe the group you want to leave.
Select 'delete' then select 'delete and Leave group'.

there isn't "leave/ delete group" what can I do?

With the new version as of March 2017, Swipe the screen to the left OR Tap on the 3 dots in the chat header & select Chat Info . Then you will find the Leave and Delete command  (go to the bottom of the page if you have many users). You will delete the group conversation from your chats list only, you won't delete the group. If you are the admin of the group you will be able to delete the group.

@Dush it's been a while, consider posting your comment as an answer because comments are not really for answering the question. (The question has been unprotected)

Directly from Viber :

Groups cannot be deleted by any one user. When a user leaves a group,
the group continues to exist with all remaining participants. When all
participants leave a group, it will automatically be deleted.

How do I use group conversations on my Android device?

Does this mean that if one user (the group admin in this case) has changed his phone number we will never be able to edit/delete the group anymore?

How to change Android default-natural orientation?
I have my device running android Jellybean 4.2.2 with Landscape as the default/natural orientation.
How can I change the default/natural orientation of the same to portrait?
Here is what I have tried till now,
1) Added setprop ro.sf.hwrotation 90  to build.prop and it did nothing.
2) changed user_rotation value in /data/data/com.android.providers.settings/databases/settings.db and it changed the orientation of apps only. the orientation of Home screen and launcher are still landscape.
3) Modified PhoneWindowManager.java similar to the one given in link : changing phonewindowmanager to change natural orientation
The third option works. But it still shows the bootanimation in landscape and after the animation is finished, the display rotates(with rotate animation) to portrait. How can I avoid this rotation and change the default/natural orientation before boot animation?
Is it something related to SurfaceFlinger? I would also like to point to this article in android website. pre rotation in hardware composer

The boot animation wont change since the boot animation where a series of images. In  /system/media you will find the bootanimation.zip if you open the zip you will find the images replace the zip with your own boot animation of portrait images. There are plenty of tutorial on how to make your own boot animation.

Thanks. I have already did that work around. As bootanimation a series of images, I have used my own portrait images and overridden the bootanimation to look like, it is portrait screen. But the real problem is after the bootanimation it rotates from landscape to portrait. I dont want it to show landscape at all. I need it portrait from the moment or before the boot animation exits.

http://android.stackexchange.com/questions/10808/how-is-the-default-screen-orientation-in-android-specified did u try this?

Yes i did. The second option i have given in the question explains the same.

I hope there is a generic solution for this. May be some changes in surfaceFlinger , inputReader or something like framebuffer rotation.

Working Android 4.2.1 method.
Tab or phone must be ROOT.

1/
Dowloand in playstore : Root Browser
Dowloand in playstore : ES File Explorer

2/
Open Root Browser and go to : system folder.
Then show file : build.prop and touch it long time.

in menu choose : Copy and past file in your internal or external sd card.

3/
In Root Browser open build.prop copied file with ES File Explorer
Then modify entry : ro.sf.hwrotation=0
Must be 90 to setup default landscape mode :
ro.sf.hwrotation=90

In ES File Explorer save build.prop file.

4/
Open Root Browser, go to system folder.
Delete (by menu) build.prop file.
FOR SECURITY BACKUP THIS FILE or SYSTEM BEFORE.

Go to your sd card and copy build.prop modified file.
Past it in system folder.

Touch build.prop long time and set Permissions to rw-r--r-- (0644) :
READ -> Owner -> checked
READ -> Group -> checked
READ -> Others -> checked
WRITE -> Owner -> checked
And lets all others entry unchecked and click OK.

5/
Reboot. That's all.

Thanks. Even though its being long after the answer has come up, The question itself tells that this has been tried in a code level and it explains the result and issues. Please check back.

There's an App called "App Settings" for Xposed Framework.
repo.xposed/appsettings
With it you can change orientation, dpi, notifications, etc. of each individual app. But not the boot animation like samnaction explained.
Alternatively, i found this on stackoverflow:
changing-android-device-orientation-with-adb
So you could make a script like this
#!/system/bin/sh
content insert --uri content://settings/system --bind name:s:accelerometer_rotation --bind value:i:0
content insert --uri content://settings/system --bind name:s:user_rotation --bind value:i:0

and put it in /etc/init.d for executing at boot (if you're on stock, you have to mod your rom to have init.d.)
edit:works just on Android 4.3+

Cannot connect my Moto X to Windows 7 PC
I cannot connect my Moto X to Windows 7, 32-bit PC via USB. After doing some research normal solutions people found were

Enabling MTP in connection settings.
Disabling USB debugging in Dev. settings.
Updating drivers.
Updating windows media player.

I've tried all of this still my PC can't detect Moto X as USB storage device. It shows the device in - Control Panel\Hardware and Sound\Devices and Printers, but says this device does not work properly as Windows cannot load its drivers. It gives option to re install drivers in troubleshooting but everytime I do it the device driver is not successfully installed.

https://motorola-global-portal.custhelp.com/app/answers/prod_answer_detail/a_id/94931/p/30,6720,8696/action/auth try installing this

@sameer I've already installed it... Even tried re installing it several times still it doesn't work.

Goto device manager and right click on the motorola device name and select Update Driver Software and click browse and point to the driver location.

It says device driver is already installed... @sameer

connect your phone with computer
go to C:\Program Files\Common Files\Motorola Shared\Mobile Drivers\
run Motorola Driver Installer.exe, choose clean and Reinstall.

That is not helping either... @sameer

It should work. Try in different port or in different pc

it works in other PC without even installing drivers it automatically installs drivers from windows 7 database in other PC... the problem is with this PC only..

Take a look at this question/answer. The device is different and the drivers are too, but the method should be the same.

If your phone is able to connect in another PC, the problem is in PC and not with the droid. The possible solutions are

Download Motorola driver
Goto Device Manager and right click on the motorola device name and select uninstall
Now right click and select Scan Hardware Change Now select Update Driver Software and click browse and point to the downloaded driver location

If this does not work Try:

connect your phone with computer
go to C:\Program Files\Common Files\Motorola Shared\Mobile Drivers\
Run Motorola Driver Installer.exe, choose clean and Reinstall.

or
The problem may be due to windows mtp driver and you can try the fix provided by Microsoft.
or

Unistall driver from device manager
Remove all USB controllers
Disable Windows Media Player (Control Panel - Uninstall a program - Turn Windows features on or off - Expand Media Feature - Uncheck Windows Media Player)
Connect your device and Reboot the pc
Reactivate Windows Media Player(Control Panel - Uninstall a program - Turn Windows features on or off - Expand Media Feature - Check Windows Media Player)

I formatted C drive and reinstalled windows.. And now it works without installing drivers too... thanks for the help though...

OK, I pulled my hair out for almost 2-days.  I'd install the Moto USB driver ware on my PC (Moto Device Mgr V2.5.4) and when I'd connect my Moto X via USB, the driver wouldn't 'install' properly.  Status via Cntl Panel, Device & Printer, showed a device named XT1095 (yep that's my Moto X) but flagged with a yellow exclamation point and the declaration 'Driver Not Installed'.
After a NUMBER of uninstall/re-install episodes and delving into the Moto X (turn developer USB options ON/OFF), I tried the setup on my older Dell laptop.  BINGO, everything worked like a hose!  Hey, what's the difference?
Well, one thing is the Dell hardware is specifically limited to USB 2.0.  My desktop PC running a quad core based motherboard has both USB 2.0 and 3.0 ports on it.  Hum...
I did a clean install of the Moto Device Mgr and then connected my unlocked/running Moto X intentionally to a USB 2.0 port.  KAZOOM, the device driver installed and all was working!  Then, I unplugged the Android phone and re-installed it on a USB 3.0 port where it had previously failed to work. VAROOM, it came up and running nicely!
Methinks there's an issue here of technical due diligence in testing the Moto USB driver with various hardware manufacturer specific USB ports...

Have you tried unlocking your screen after plugging in the USB cable?
I was having a similar issue - my Moto X would charge but not connect as media device - but none of the above advice was relevant. Finally, I realized that it would not connect as long as the screen was locked. After entering my PIN, it connected immediately. In retrospect, this is a really obvious security feature! Just thought I'd post this in case someone else has also misdiagnosed this as a USB issue.

I was facing the same problem with my moto e and windows 7 professional, XP i.e. unable to connect.
Earlier, it did connect with every system but for the last few days it did not.
Today an IT person gave me another USB cable (thicker one) and it worked.

+1 for the suggestion. After researching different USB cables at http://www.cablestogo.com/learning/connector-guides/usb , swapping the USB cable from "Micro-USB A" to "Micro-USB B" solved the problem. The "Micro-USB A" cable did not work because Windows recognized the phone as a generic usb device. On the other hand, both Windows and Motorola Device Manager see the phone correctly when using the "Micro-USB B" cable.

Okay this is extremely weird, but I've found this with more than one laptop (one HP and one Acer). For some reason the second USB port from the front of laptop never works with certain devices. My 3G dongle and now my Moto X would not be detected properly and said 'unrecognized device'. I had the same issues as the original question, but after switching ports it just works, every time. Hope this helps someone.

To make a Moto G device work with Windows 7 computers, go to Settings > Developer options on the device and select USB configuration. Change it to PTP (Picture Transfer Protocol) instead of MTP (Media Transfer Protocol).
I have been racking my brains and searching the phone and web for answers. Poking around the phone did it! Good luck :)

Had the same problem and nothing worked until I made sure I was using a USB data cable. Maybe the one I was using is for charging only

This doesn't really answer or attempts to answer the question. OP clearly mentioned that (s)he tried changing USB connection (MTP, USB debugging) which IMO cannot be done if the cable is for charging only.

Android Transmit system audio over MTP
Here is what I want to do. If I plug in my Galaxy S4 to my BMW 335i, then I can browse and play music stored on the device just fine and the sound quality is excellent. If I play over the audio auxillary input, I can play anything but the quality of the sound is not good at all. The only way to play system sound and services like Spotify, Pandora, Google Music, etc is though the aux input jack since MTP doesn't carry the Android devices audio output.
What I want to do is transmit all system audio over MTP when the device is connected. This should be doable through some app or through some custom code that would basically buffer the system audio output and push it over mtp. Ideally, you could just browse to an item in the BMW iDrive that says "System Audio" and then you could hear any output from the Android phone regardless of what app is playing it.
Does anyone know of an app that would route system audio over the MTP connection? or does anyone have a service or custom code that would route all audio over the connection?
I have the same problem with Bluetooth audio as well. The 2010 BMW I have doesn't support Bluetooth Audio, but I really don't care about that since that sound quality is pretty questionable as well anyway.

No, MTP doesn't work like that. MTP is a client-server file transfer protocol, a bit like FTP. Your best bet is to either find another protocol the car supports (there are many network audio protocols, so it's likely it'll support one), or failing that, fix whatever is making the aux input sound bad (most likely a bad cable or connector, or the car is expecting line-level instead of headphone-level audio).

Disable full screen view in Google Play Books
On my 2013 Nexus 7, the Google Play Books app makes use of the new full screen feature in Android 4.4 KitKat to hide the system bars when the app is in use. This adds nothing useful to the experience, in my opinion, and requires annoying extra taps for trivial tasks like looking at the clock or switching apps. I can find no settings in the app for this. Is it possible to disable this "feature," preferably on a per-app basis?

Immersive mode is non user configurable I'm afraid. However, with a rooted device you could install the Xposed framework and 'Gravity Box Kitkat' and then you can add a toggle for Immersive Mode.

I HATE immersive mode... Going to switch to an iPhone I don't like being a gunnie pig and having my opeating system change fundamental functionality release after release.

Why does heat problems cause purple tint / pink spots on my camera (HTC One)?
A while ago, I got a new HTC One m7, It is the best phone I've had, but it has one BIG issue, its camera sucks on low light.
I've investigated the issue, and I was told it could be alleviated with a software update, and it's been almost a year, and nothing.
The problem is in fact a hardware issue, where heat causes something on the camera, so it adds this annoying purple stripes/haze: Stripes Image, Tint image. And this hardware issue comes, apparently because there is a lot of strain on a chip (Zoe?).
Photos taken with flash look extremely good though. So my question is...
Why does this happen?
I'm not looking to know what causes the phone to heat up. I'm asking why would purple tint/stripes appear there.
What is happening to the lens? or... is affecting the image processor chip? if so, in what way?
Or... is it caused by something else?
And... How come it does not affect my flash-taken-photos?

An an update, my phone has been repaired <3

The HTC One's camera has bigger pixels than the regular phone cameras ("Ultrapixels"). When you use your camera in low light, it tries to draw more light from the sensor, so the image looks brighter.
The "purple" issue is caused by bad heat insulation of the camera sensor from the rest of the phone, so when you try to take a photo the heat can cause distortion of the data the image processor chip collects from the sensor and converts to digital image (when you open the camera app it puts the screen brightness to max, so even this can cause the phone to heat up). When you use the camera in low light the image chip relies more on the sensor to collect more light, so this might cause only low light pictures to be affected (especially the color black, where the sensor tries to deliver as much light possible and there just isn't one, as it is dark). When you take a photo in normal light (or with flash) there is enough light and the sensor doesn't try to replace the color black with purple.
The damage to the camera sensor caused by heat seems to be permanent and if it's in an early stage it can be fixed by a software update which just calibrates the image chip to ignore the "purple" image data. But, as you stated, this is a hardware issue and if the software update doesn't fix it, the phone should be sent to a repair center for the sensor and the insulator around it to be replaced. As of November - December 2013 the new sensors are made by a different manufacturer and lack the issue.

Tablet with android 4.0 update to the latest android OS? (currently 4.4)
Is it possible to update a tablet that has android 4.0 to the latest version (4.4.2)? I'm looking into buying a tablet. It has android 4.0 which is cheaper than the other tablets that have 4.0 (which doesn't make senec to me).

Could you tell me the science behind this though? Why is it that a device can not "update" even on the same version number.

It's up to the manufacturer to port new versions of Android to their device and release the update. See also the answers to this and this existing question.

Didn't see this comment until now. Thank you.

Phones and tablets (especially cheaper ones) generally don't have much storage space, and their other components are not that powerful (low memory, slow processor, etc. The Operating System that runs on them must therefore be kept to its absolute minimal size, and be heavily optimized to the very specific hardware inside.
For example, in order for Windows to support a wide range of personal computers from various manufacturers, it ships with a myriad of different drivers, some are generic to handle multiple versions of hardware (i.e. video cards or sound boards.) This way one or two (32 bit Vs. 64 bit) installation packages can be distributed by Microsoft that would be able to be installed on pretty much any compatible PC.  The flip side is that this makes Windows installation huge in comparison.
On the other hand, Android at its lowest level has something called "Kernel". This is what allows the rest of the OS to communicate with RAM, screen, CPU, camera, buttons, etc., and is equivalent to drivers in Windows.  See this diagram of Android software stack.  Due to the above mentioned restrictions, the kernel must be tailored to perfectly match the specific device Android is to be installed on.  This way its size can be kept minimal, but the downside is that it would be incompatible with another device, even from the same manufacturer, that has slightly different components.
The kernel is developed by the device's manufacturer such as Samsung, Motorola, LG, etc.  Since it's based on Linux, the kernel's code is open source, but it usually contains some closed-source, proprietary code from other component manufacturers such as CPU or GPU (e.g. Qualcomm or Nvidia) in form of binary blobs.  Then there is a layer of customization that manufacturers and carriers add to "stock" android, which is also usually closed-source and proprietary.  Sometimes it's a couple of extra apps, but usually these customizations are more invasive in a form of a different user interface, as with Samsung's TouchWiz, or HTC's SenseUI.
When Google releases an upgrade to Android, they are changing all of the Android's software stack, including the kernel, libraries, runtime, framework, and applications.  You can already see where the difficulty is in upgrading a device.  Google's changes require the manufacturers to update their code for all the drivers for each specific device in the phone/tablet.  If Samsung uses Qualcomm's CPU/GPU instead of their own, they will also need to wait for Qualcomm to update their binary blobs.  The same goes for every other piece of circuitry: Wi-Fi, Bluetooth, cellular modem, flash memory controller, etc.  Manufacturer of each of these components will need to see if Google's changes require them to modify the drivers that will be included in the kernel, so that the phone continues to work normally.
This is also the reason why an Android OS upgrade intended for a specific phone cannot be simply "flashed" onto a different one.  Different phone models even from the same manufacturer will usually contain different hardware, thus needing a customized kernel.
Now consider the costs to the manufacturer to upgrade every device model they make every time Google releases an upgrade to Android.  Their software engineers must review the changes in the upgraded OS, modify their code for every driver, thoroughly test their changes to ensure their changes don't break anything, and release the final code for roll-out.  Now multiply this by every phone model they've released since the last Android upgrade.
Cell phone giants like Samsung or Motorola can afford this process in the name of customer satisfaction and brand loyalty, but small-time manufacturers simply don't have the resources for this.  There's no incentive for them to upgrade the devices they are probably already selling at razor-thin margins in the first place.

Wow. I truly appreciate this. Thank you.
Not to take away from your post, let me see if I truly understand this. Is it that diffrent versions of android OS is linked to hardware of the device which is linked to the way the manufacture code(kernal). It will not be cost effective to "update" old android devices because of the old hardware built in them.

@PassingBy That's the gist of it, yes. If you follow the link Dan posted in his comment, you can see that what I posted is actually is an over-simplification of the actual upgrade process for a manufacturer.

Is there anyway to save my contacts and texts on a Samsung Galaxy Nexus with broken screen?
Broke my screen, and it's dead. I searched the forums, and I could not find an answer. I don't care about my media files, but my contacts are really important to me. I already ordered the new Nexus 5, but I need those contacts.
I tried Holo Backup, and it doesn't work. Any Ideas?

@DanHulme No, I turned on USB debugging.

Also see: How do I backup data (SMS/contacts) from a device with a broken screen?

I'm missing some information:

Is your phone rooted?
Do you have USB debugging enabled?
Are your contacts synced to your Google account?

Since it isn't clear from the question - have you checked that your contacts aren't already backed up to your Google account? If you had your contacts synced - then they should all be backed up to the cloud / your connected Google account.
If that's not the case, and all you need is to be able to see your screen and control your phone (via the app of your choice) - you can try this kind of solution - an an MHL-enabled USB port.
Also, maybe Airdroid, can help as well.

My brother had a Samsung galaxy S-4, and he started having minor issues with it so he brought it into the store. the end result was him walking out with an S-5, and he explained to me a galaxy-specific process that allowed him to put everything into the new phone. his contacts, wallpapers, music and everything else. i assume that he started the process on the older phone, and this might not be helpful to you, but that's all i know and hopefully this is helpful to you somehow. wish i could do more, that's awful.

i can barely beleive how useless this answer is. but i figure it's better to say something than nothing at all.

Speaker not working
My phone has been working fine but since a few days ago I noticed that the speaker doesn't work on SMS notifications and music. In order for it to work, I must insert and remove headset jack. But when I restart the phone it doesn't work again so I have to insert/remove the headset jack everytime. Any ideas how to fix this?

What Cyanogenmod version are you using?

@DanHulme  cm-7-20130301-NIGHTLY-cooper

Most likely this is a bug in the ROM you're using. Cyanogenmod nightly builds are unstable and often have missing functionality: they're not recommended for everyday use, only for testing. Try updating your ROM to a more stable build of Cyanogenmod, if one is available.

No USB storage mode for Asus MeMo Pad 7 to do Android development
I intend to develop with an Asus MeMo Pad 7, but I can't set it to detect as a normal USB storage device.
In the Storage menu I have 4 options:

MTP - to transfer images
PTP - to transfer images
USB charge mode -no USB, just charging
CD mode - a CD image

I enabled Developer mode and set USB debug. I still can't see the tablet as an USB Storage.
What mode should I use for Android development?

Why do you need mass storage mode for development? That's what USB debugging mode is for. The two are not related, and most newer devices don't support UMS anymore (see, e.g. How can I use my Galaxy Nexus as an external USB storage drive?)

I based my opinion on the phones I've used so far, but it seems, new devices don't care about USB mode, they just work. I used MTP and my Android IDE recognized the device. It made my day.

Synchronizing S-Note notes between S4 and Note 10.1 2014
Some time ago I used a pair of devices: Samsung Galaxy S4 and Samsung Galaxy Note 10.1. I noticed, that they synchronized the notes in S Note nicely: even though S4 was unable to edit complex Note's notes, at least it was able to display them. And they were synchronized with my Samsung account as well.
I've replaced the 10.1 with the Samsung Galaxy Note 10.1 2014 edition1 lately and I've noticed, that it no longer synchronizes notes with my S4. Do you know maybe, why is it so? Is there a way to synchronize notes between my devices automatically?

1 Samsung for sure sets the records in their devices name lengths...

What app are you talking about? S Note, or something else?

@DanHulme The default one, S Note.

Possibly silly question: have you signed into your Samsung account on the Note? Have you set it to synch? (I uninstalled S-Note on all my samsungs so I can't check the settings for you). There are some teious looking work arounds for this (seems to be an issue for everyone): http://forums.androidcentral.com/samsung-galaxy-note-8-0/268797-s-note-not-syncing.html  May be more effort than it is worth. You could use Evernote or such and just export all your SNotes to it, and not have this again I guess.

I have seen a similar issue trying to sync S Note's between a Galaxy Note 3 (smartphone) and a Galaxy Note 10.1 (as well as to a Galaxy Note 2).
The issue seems to be in the version of S Note running on Android 4.3.
On my Note 3, S Note saves the files as .spd files in a Snotedata folder.  On the Galaxy 10.1 the S Note documents are as .snb files in the "S Note" folder.
I think this explains why sync isn't working.

Must a USB OTG adapter be used to connect a DAC/amp to an Android or can I use a Micro USB to Micro USB cable?
I'm trying to connect a DAC/amp with a micro USB connection to my Android smartphone. Is it possible to get the DAC/amp to work without the larger "adapter" type OTG cable, and use something like this instead? (A USB micro male to USB micro male cable)

The red cable pictured is a USB-OTG cable too. It's no different to having the adaptor-style cable with a normal USB-A to micro-USB cable attached. So if your amp will work with one, it will work with the other too.
Just be extra careful when using a symmetric-looking USB-OTG cable. USB-OTG works by having the pins wired differently in the "host" and "peripheral" ends of the cable, so you need to be careful to plug the "host" end into the phone. Different cables have different ways of identifying which is which, so be careful to check the instructions that come with the cable.
Of course, your amp might not work for other reasons. If it lacks an external power supply, then it needs the host device to supply enough power for it. Most smartphones can't supply a lot of power via USB-OTG, so in that case you'd need to use it with a powered USB hub.
The other reason it might not work is if it uses the USB audio profile. Most Android devices lack driver support for USB audio; there are other questions about that on the site.

Thanks Dan, when you say "need to be careful to plug" the proper side to each of the components, host vs peripheral, do you mean it will damage the phone/dac if I accidentally mixed the two? Or do you mean just take note of the difference? And also, the "powered USB hub", does that mean any USB hub? Or one with two cables to the hub? Thanks again.

Unless the amp is badly designed, it shouldn't be damaged if you get it the wrong way around: it just won't do anything. A powered USB hub is one with a separate power cable and transformer that you plug into the mains (or possibly a car lighter socket or something like that). Whether you need one depends on how much power the amp draws and how much the phone can supply.

How do I root my Samsung Galaxy S5 (SM-G900V)
Guess I might as well grab this one since it doesn't exist. I listed my specific carrier's model in the question because that's important, however the CW post for rooting states there should only be one question per model, so answers for other versions of the GS5 are appropriate answers for this question, they just won't be marked as answer from me.
I haven't been able to find solid information for rooting the Samsung Galaxy S5, has anyone had experience with rooting this model?

The Verizon and AT&T versions have locked bootloaders and are not able to be rooted at the moment.

Verizon and AT&T phone can now be rooted using towel root. Get it here http://towelroot.com
This exploit takes advantage of a vulnerability in the Linux kernel. I have tested this and it is working on my sm-g900v
Just download the apk and run it. Press the button once the so loads and you will be rooted in less than a second. Give props to geoshot who developed the exploit so that he will be inclind to do more work like this in the future.

CF autoroot
But it will trip knox
http://autoroot.chainfire.eu/

Not seeing the 900V listed at that link you provided.

Galaxy s4 had the same hardware on all carriers.
S5 should be the same way.
It will work. worst case scenario just means a trip to odin.

Sense 5 mods on other devices
Is there any method to replicate the interfaces as in HTC Sense 5 on other android devices ?
I have nexus 4 and samsung galaxy s III and I would like to have the recent app and blink feed as on Sense 5 ROMs.
Is there any Sense 5 ROMs for those mobiles or is there anything that would make it possible to have these features on mentioned devices ?

Since HTC Sense is non-free software, using it on a non-HTC phone would be software piracy. The best you can hope for is a third-party app or ROM that aims to look similar.

Is there any sense ROMs for those devices ?

Sense is made by HTC for HTC so no you can't put it on other phones. That said, I recently read an article that Blinkfeed and some of their other cooler closed source apps are going to be made available on the play store for other devices later this year. Looks like Blinkfeed specifically is already avaialable. Hope this helps.

why smartphones become laggey and slow with time?
I found a lot of info about how to make my smartphone faster but I couldn't find the reason for smartphones lowliness.

I found that you should move apps to SD Card (if you have one)
Don't use a lot of widgets, try not to use too much home screens.
Remove apps that you don't use. Turn off animation.

And more stuff like this.
But what makes the phone become slow with time?

Same reason a PC becomes slow over time. A lot of crap ends up on the system. For instance; even when you uninstall apps many of them many times leave something behind. The internal android DB becomes full and becomes harder to search because of the large amount of data.

Is their a good app that can clean this app (with root)?

There are apps. But I never used any of them so I couldn't tell you

How to do a factory reset on Xperia Z with broken screen?
The screen on my Sony Xperia Z is cracked. I have now sold the phone so I need to delete my text messages, can anyone help?
I can only press in certain areas of the screen so I can't click on factory reset or delete messages one by one.

Are you able to press your home keys and stuff? I mean the bottom panel keys, all of them.

Is your phone rooted?

The simple way to factory reset for unrooted phone is to perform a factory reset via pc companion.

Download PC COMPANION and install
Open up PC companion and click on Software Repair
Optional: If your screen is locked and you can't unlock it, check the "I can't start my device"-checkbox in the lower left corner. Click "Next".
It will say could not find phone because you haven't connect it yet! so, do connect it and click on the repair phone like this picture. Follow onscreen instruction.

This is the only thing that worked for me after about 30 minutes. It's been much easier with all my other phones!

See whether your phone supports OTG. If so, use an OTG cable and then connect the mouse to your phone. In place of touch you can now use the mouse and then reset it via normal way.

How to do that exactly?

See your phone supports otg so use an otg cable and then connect the mouse to your phone.in place of touch you can now use the mouse.voila!

Works like a charm!

I'm assuming that you can't factory reset it via the OS, so the best thing you can do is to boot into recovery mode. This is of course as long as you can see the options on the screen. So once in recovery mode, you can select the option to factory reset the entire phone, apart from your SD card that is.
Entering Recovery mode

Restart your phone.
When your phone's notification LED is pink, or any other colour, press the Volume UP or Volume Down button a couple of times.
You should now be looking at the recovery mode screen.

Once you're in recovery mode, it should be pretty easy for you to navigate up or down, using the volume buttons. Select a preferred option by pressing the Power button.
Just look for the option to reset your phone.

This works only if op is rooted and has CWM.Sony Xperia devices don’t ship with a pre-installed recovery. So unless you’ve installed a custom recovery on your device, you won’t be able to boot into recovery mode.

Updating to CM11 - (Status 7) Installation aborted (i9300)
I'm trying to install CM11 onto my Samsung Galaxy S3 (i9300) so I can have the new Google Camera and Chrome Remote Desktop apps.
I tried to install initially via the usual update menu, but got an error and it went to ClockworkRecovery Mod. After much messing around, I downloaded this zip and put it onto an SD card and tried to install it using CWM but I get the following error:

Error in cm-11-2014005-SNAPSHOT-M5-i9300.zip (Status 7) Installation
aborted

Any ideas please? It sucks being without a phone, and I don't want to wipe everything and start again if I can help it since I'm pretty sure I have things on there that aren't backed up (that'll be my first job when I get this working again!)
Thanks :)

Are you sure your S3 is the i9300?  GT-I9300 is the international model of the S3.  If you are in the US, your model number is most likely different depending on the carrier you bought it from (unless you imported it from overseas.)  Here is a listing of all the S3 model numbers.  After determining your S3's actual model number, you can download the proper version of the ROM from here.

Thank you, I'm from the UK and it definitely is the i9300 :)

I hate to answer my phone question on here, but finally sorted it! Thanks to Adach1979 for pointing me towards a useful resource too.
In the end I had to put CM10.2 onto the SD card and install that using CWM - it wiped all of my data (urgh) but at least the phone was working again.
I then used Cyanogenmod's fantastic installer to get the latest version - http://beta.download.cyanogenmod.org/install
I then had issues where the USB kept disconnecting, apparently this is common on Samsung devices and I managed to fix it by using Zadig and these instructions - http://forum.cyanogenmod.com/topic/82393-samsung-devices-we-couldnt-talk-to-your-phone/
And now, almost 4 hours after I started, CM11 is finally installed on my phone! :)

A quick google search turned up this.

Thank you, unfortunately I cannot install the previous version since it seems I can't browse through the files on my phone using CWM :( I can only browse through the SD card, and I cannot remember the exact version I used before

Quick update - I'm trying now with cm-10.2.0-i9300! Thanks

just to collect more information with this question for future use of it, what Recovery did you use? Maybe the zip you downloaded was corrupted or for another device. Indeed, I had the same problem with my I9505 trying flashing a Niglty build of CM11.
Let me know!
Regards,
Luca

Hi,I tried to use CWM - not sure what version sorry! I did try installing two different versions of CM11 though and got the same problem both times. I also tried editing one of the files in a text editor as recommended by an online guide but no joy with that either. I think the problem was possibly due to using an old CWM version

I think the problem is with the recovery. Use the recommended version of CWM recovery. Also check the md5 checksum of the CM11 zip file u downloaded to see if its intact.

Find when an app was released on the google play store
I tried searching for a tool online but couldn't find how you can find out when an android app was first released on the google play store?
On google play it just mentions when it was last updated. Any ideas how I can find the first release date ?

Why does my keypad fails abruptly?
I use samsung galaxy y duos.And my samsung keypad fails abruptly at times.When I tap in the places where I need to give in the words,keypad appears but when I type in, the keypad works nice but there aren't any word in the input box.It happens in all kind of application and messaging.What should I do prevent this happen ever again.Somebody please edit this question with good english.

I had similar problems with my  new Samsung Galaxy Tab 3. When I wanted to write a post
for a forum I got the writing window and the keyboard but when I typed three letters
the keyboard vanished and this problem continued.
Later I discovered how to really shut down the tablet by pressing the switch-off a bit longer.
Then I got a message: Switch off the tablet? I clicked okay. When I turned on
my tablet again after some time the trouble with writing was gone.

Problem persists even after doing.Will this be an activity by a virus?

Call recording for Galaxy S2 with kitkat ROM
I'm looking for a call recording app \ mod that works on Galaxy S2 with android 4.4 ROM.
I used several apps with previous versions (mainly on stock ROM's) but none of the apps I tried worked on KitKat ROM
Currently I use Resurrection Remix ROM but I don't mind changing to a different ROM (I understand that CM based ROMs don't have call recording support)

My suggestion is to go for Call Recorder - ACR, it works fine with my CM11

Samsung S3 - 40mb free ram of 1.5 gigs?
My S3 has been lagging while I play in games or use aps. I've read that free ram is not supposed to be linked with lag but it seems that it must be. While in one of the games I play, my keyboard will not load, or will close randomly. I assume this is due to lack of ram to open it.
I have very few aps and almost no background processes. How is 1.44 gigs of my 1.5gigs of my ram being consumed?

on the Play Store there are several utilities to clean Phone and speed up processes. My favourite is this:
https://play.google.com/store/apps/details?id=com.cleanmaster.mguard
Your excessive use of system RAM is (maybe) due to some persistently active process on your phone. Follow this guide to see yours (and maybe evaulate a uninstallation of some):
http://www.wikihow.com/See-What-Apps-Are-Currently-Running-on-Android
By the way, can you please tell us more information about your Android version?

ADB backup is not working
I just tried to make a backup from my Nexus 5 (before installing CM 11) It is unlocked but not rooted. On PC side I'm working with Ubuntu 13.10.
When I type
adb backup –all -apk -nosystem –f /data/Nexus5Backup/backup_17042014.abk

then my phone asks me if I want to backup and I confirm. But the terminal in Ubuntu immediately returns to prompt (~$) and my phone says the backup is complete.
When I type
adb backup –all -apk -shared -nosystem –f /data/Nexus5Backup/backup_17042014.abk

and also confirm that I want to backup then the terminal hangs at
Now unlock your device and confirm the backup operation.

The phone is displaying "shared storage".
But the weirdest thing is that in both cases the backup file (/data/Nexus5Backup/backup_17042014.abk) is never being generated.
How can I do a full backup? I already did backups in the past and they worked. Is this a bug in my Android version (4.4.2 KitKat)? And is there a workaround?

This solution worked for me:
http://android.stackexchange.com/questions/83080/adb-backup-creates-0-byte-file-prompts-for-current-backup-password-even-though/130421#130421

This solution worked for me:
http://android.stackexchange.com/questions/83080/adb-backup-creates-0-byte-file-prompts-for-current-backup-password-even-though/130421#130421

I asked this question some time ago and as I weren't able to fix it, I simply forgot about it. However as adb backup seems to work again for me and because it may be an issue for others I'll post here, what has changed since last time.
Actually an update fixed that issue. So I guess it was a bug. I can't determine which version it was but everything works fine at least since the versions of Ubuntu and adb you can see below. If the tip of matt wilkie doesn't work out for you and if you are using an older version of Ubuntu and/or adb I strongly recommend an update.
$ adb version
Android Debug Bridge version 1.0.31
$ lsb_release -d
Description:    Ubuntu 14.04.2 LTS

Is ADB hung or just inconsiderate in reporting on what it's doing?
I came here with a similar question; on Win7 adb backup -apk -shared -all -nosystem -f path\to\backup_file.ab the Nexus 5 reported "com.stuff.foo .com.stuff.bar" ... for awhile and then stopped for a very long time, 20+ minutes, on "shared storage".  Jacking up the confusion and anxiety level, after I picked up the phone when the screen blanked, the display auto-rotated, and then from that point didn't show any status messages at all.
On the PC side, the console never reported anything other than the initial unlock device message.
What kept me hanging in was that the backup_file.ab was created, the time-stamp continued to match current time within a minute or so, and the file size was multi-GB and kept increasing slowly -- albeit in fits and starts -- one pause was about 10 minutes(!), and then jumped by 0.5GB in a single shot.
After more than an hour the phone the Backup/Encryption Password screen closed of it's own accord, and the PC console prompt became active again. Neither one exited with a message to indicate whether they'd finished successfully or in an error state.
Final .ab file is just under 8GB. Nexus > Settings > Storage reports 12.55GB total space and 500mb free.
I think perhaps you just didn't wait long enough (understandable given the lack of feedback!) and that perhaps Linux spawns adb as a background process? (thus the return to prompt).

((next Q: how to verify what is in backup and that it is good?))

Actually the machine I used doesn't exist anymore.
On my recent computer with a newer version Ubuntu everything works perfectly (The file is generated and immediately grows). Ubuntu 14.04 comes with a newer version of adb. So I guess it was a bug in adb.

Just add

adb backup –all -apk -shared -nosystem –f /data/Nexus5Backup backup_17042014.abk

double quotes!
adb backup "–all -apk -shared -nosystem –f /data/Nexus5Backup/backup_17042014.abk"

FWIW, On a Motorola G3Turbo with Android 6.0, and:
adb --version
Android Debug Bridge version 1.0.41
Version 30.0.1-6435776

I had to use quotes in a rather... weird way:
./adb -d backup "-all" "-system" "-shared" "-apk" -f <filename>

Which should have been absolutely the same as no quotes at all.  Since this really, really should have been the same as no quotes at all (I am on Linux, using bash, which should have eaten the quotes itself so adb would never get the chance to see them), the likely answer is: retry the command a few times.

I had to use the quotes even more strangely:
adb backup "-all -system -shared" -f
Centos7 - Android 10
Android Debug Bridge version 1.0.31

How to fix a black screen (bricked) after rooting an encrypted device
Phone: Samsung Galaxy S3 (GT-I9300)
Per work policy to add an exchange account I had to encrypt my phone. After doing so, I needed to root it to create a swap partition as it was constantly running out of RAM. I did what I had done in the past which was to flash CF-Auto-Root with Odin3. After the process finished, the phone restarted and I was shown the usual screen for entering the PIN/Password, so I did and it accepted it showing the unlocked Android icon, but instead of booting to the OS, it froze on a black screen. I have tried flashing the stock firmware, which has had no effect. I have managed to flash the ClockworkMod Recovery, but since everything's encrypted I could not get access to any data.
Does anyone have any ideas?
Thanks in advance,

I ended up flashing the Stock ROM (using sammobile.com) back again and using the Stock Recovery to do a factory reset as the Team Win Recovery format didn't do anything.
That did the trick, but of course all data is gone too. Oh well.

have you tried to wipe your data/cache + dalvik?
For my experience, sometimes the black-screen is due to a bad-flashing procedure (not your fault) when something goes wrong.
If you did not tried yet, try and let me know!
Regards,
Luca

I've tried wiping the cache + dalvik, no change. I'd rather avoid wiping the data and lose it till I see that I have no other choice.
I've also wiped the /system and then reflashed it with the Stock ROM, no change.
Also, checking the ClockWorkMod Recovery log I see that when attempting to wipe the dalvik-cache, it couldn't find the folders: '/data/dalvik-cache', '/cache/dalvik-cache' and '/sd-ext/dalvik-cache'.
Is there a way I could backup everything (perhaps via ADB), wipe the /data and then later attempt to restore?

OK, I now wiped /data, /cache and /dalvik-cache using Team Win Recovery, and there's been no change at all. I still get the screen to type in my password and when I do, I get the black screen again.

I ended up flashing the Stock ROM back again and using the Stock Recovery to do a factory reset as the Team Win Recovery format didn't do anything.
That did the trick, but of course all data is gone too. Oh well.

Is there any way to check the phone before buying a new device
My friend is buying xperia Z1. The actual price of the phone is around 40000 INR but he is getting it around 25000 INR. It has 1 year seller warranty with all accessories.He said the phone is imported. I dont understand why the price is so low.
The software bug can be fixed. But I am concerned about the hardware issues. Any idea on how to check whether the chipsets were original.
I planned to run a benchmark tool after he gets the phone. Also to check the service menu. Any other ideas to check?
Also I have the doubt on benchmark tool. Will it read the hardware correctly or it just read the phone name and based on it, it will produce the specs from the database?
What i fear is the clone models. I heard about them but I didnt get any chance to see them. Is it difficult to separate clone from the original.
Thanks in advance.

To start with, I don't think it's possible to somehow change chip on a phone. It would stop working because of incompatible drivers.
Price of the imported phone can be lower, for example Nexus devices are 1/2 more expensive in my country than in the US and it could be used too. Anyways you should check, if it'll work on your carrier if it's imported.
Finally, there are many benchmarks to choose from. I suggest using AnTuTu. It's been here a long time and is still one of the best. It really tests your device, cause I've used it on different ROMs on one device and I had different results.

Is there any way that these phones were failed during factory test and it been packed and sold for low price?

I think maybe some employee of the company could carry out some faulty devices but I never heard about something like that. Company itself wouldn't do that.

How to insert "blank character" in WhatsApp?
There is a blank character (kind of box) that can be used in WhatsApp to set blank status or send blank messages.
How to create/type or find that character?

The methods shared here unfortunately do not work; the Arabic Character used to work but it stopped working since long.
The only character which seemed to work was the Reverse Character Unicode [which I discovered in 2005]  Pasting or Opening it on a PC messes it up.
Afterwards I stumbled on another unicode character which would work (on most devices) even when shared through PC etc.
Copy the Space visible between the bold brackets [  ] .
If for some reason you fail to copy it from above you may copy it from my blog > here.
The box type thing you mentioned appears on Apple devices and the proper technique wouldn't result in a box type thing even on Apple devices.
Fun Fact : I was the one who worked out the "blank character" thing on the internet more thn 2 yrs back and finding others using(stealing) even "my images" spoils the mood, thus I came here to post the same.

Just copy the character between the quotes: " ", and paste it wherever you want.

Just go to your computer, go to character map (or a word document) and hit ALT + 255 or ALT + 0160 and copy that file into your phone. Then open that document on your phone, copy the text and paste it wherever you want.
However, if you don't want to waste time doing all this; just go to your WhatsApp settings and hide your status.

Method 1 – Using Arabic Words

Copy this content >> ” ﱞ  “
Make sure you have copied the message with (double quotes).
Paste this content on WhatsApp.
First, try to remove or delete the left quote.
Later try to remove or delete the right quote.
When you will try to remove the right quote, everything will be gone.
Done… Tap on send button to send a blank message.

Method 2 – Using Alt + Key Combinations

Open Notepad on PC or Laptop
Press ALT + 255 (Hold Alt Button and Type 255).
The above key combinations will generate a blank space.
Now save this file on the smartphone (PC > PHONE).
Before sending the message, open the file on the phone.
Copy the content.
Open the WhatsApp and paste the content to send.
Done… You have successfully sent a blank message to your friend on WhatsApp.

Move to SD card not enabled in Sony Xperia M
HI i have a sony xperia M Mobile. I'm trying to move downloaded apps to SD card. For that first i installed android sdk in my pc and connected my Device in USB debugging mode. Later i started adb and changed the installed location to external card by using pm set-intall-location 2 No errors are shown here. But after disconnecting the usb i still can't find move to SD tab in my device for any of the downloaded apps.
After setting adb i viewed adb devices i saw the devices list there is only one device connected with some name. I assumed it as my device as there are no other devices connected but how can i know that it is my device only.
My device is not rooted

You can't move apps to sdcard on the Sony Xperia M. Unless your device is rooted.

Don't know why it was downvoted. Though he doesn't explain why, this answer is right.

Are you sure that after rooting you can? I think in Android 4.3 this functionality is missing :-(

Sony Xperia phones don't support moving applications to SD Memory card anymore. That's an official confirmation from Sony. I queried about this topic directly with them. The only thing you can do is to Rooting the device which obviously voids the warranty. Rooting is an easy process but finding a good Custom ROM is the issue.

Update heavly customized but stock rom Nexus 5 keeping data?
I have a Google Nexus 5 with Stock Rom 4.4.2 and:

Unlocked boot-loader
Custom recovery (TWRP)
Custom kernel (franco)
Root
X-posed framework

What is the best method to upgrade to the upcoming version 4.4.3*, keeping data?
Please answer with a step-by-step guide, possibly referring to this configuration (like: disable #5, revert #3 and #2 to stock, don't use OTA but this package from here, etc...)
Would be great to have technical explanation for each step, to make this Q&A useful for any 4.4.x-to-4.4.y Android upgrade.
Thank you.
*look at first comment

I know 4.4.3 is not yet released, but I want to be prepared :-) the link to the package can be added later

You don't need to disable anything :-)
Step-by-step guide:

Update your recovery to the latest version
Download this 4.4.3 update and SuperSu
Place these files in sdcard
Boot in recovery
Wipe Cache and Dalvik Cache
Flash 4.4.3 update and SuperSu (~15/25 mins)
Reboot
Re-install X-posed framework from its installer
Re-install custom kernel

Now you have 4.4.3 and all of your customization without losing data ;-)

According to Tested.com, reverting changes made by Xposed, making the OTA update and enabling Xposed tweaks again should be enough.
EDIT: Sorry, you need to go back to full Stock. Here's step by step guide: xda-developers.

The presence of custom recovery and custom kernel doesn't matter?

See the edit above. Sorry it took so long.

I found the right way - no need to go back to full stock. Check the current accepted answer.

How to extract GPS data from my phone
I am a database programmer, and I want to learn about geospatial pattern matching by using the gps data from my phone.
I would like to install an app that uploads a record about the location of my phone every few seconds - to somewhere - pardon my ignorance as I am not a mobile platform developer. Presumably I can point the uploading process to some sort of a listening process on an Amazon AWS machine, where I can install a database and then analyze the data.
Is there any android application that I can install that would allow me to do this? By using an app, I can ask some friends to do the same so that I can then analyze data from multiple devices.
Whats the best approach for this type of task?

You could try GPS Logger for Android.

A lightweight, battery efficient GPS Logger. The purpose of this app
  is to log your GPS coordinates at specified intervals to a file on
  your SD card. This app runs in the background so that you can on a
  long walk, hike, flight ride or photo session or even go buy some milk
  and have this running as long as possible. Once you're back at your
  computer, you can then use the files to geotag photos, upload to
  travel sites, view in Google Earth and so on.

The app lets you send the data via email, FTP, DropBox, Google Docs, OpenStreetMap, or OpenGTS. What you do with it, programming-wise, is entirely up to you; this part is off-topic here.

The easiest way to do this is use Google Location Sharing/History, a.k.a. Latitude. Your phone already has all the functionality to do this: you just need to turn it on. Then, you can use the API of Google Location Sharing to retrieve the location history of the phone and process it any way you like. You don't need any server-side programming to do this.
All that said, probably the best way to get into GIS programming is through OpenStreetMap. It's a huge, complex dataset and offers lots of opportunities for analysis and for learning about different ways of storing, representing, and processing geographic data.

I'd do it by using the free version of Endomondo. On your site profile, you can than export the data in .gpx or .tcx format.

Here is the solution that I had found after doing some research. This I guess this is the only service that can index, store and pull up data quickly without impacting system performance.
Your applications can benefit from not having to deal with this time-consuming task similar to how you would access and use a mapping service provider.
It analyzes the GPS data for you in real-time so you can use the analyzed information to drive your applications and services and provide solutions to your clients.

3x4 keypad only types numbers even when in the letter mode is shown
I hope anybody can help me out. Any tips would be very much appreciated!
I changed the keyboard input mode from qwerty to 3x4, as I can't manage the small buttons of qwerty. I realize the 3x4 has a letter mode, a number mode and a symbols mode. I can see the alphabet characters on-screen, but pressing them produces numbers.
This is me typing 'hello' on the keypad, once with XT9 on and again with it off.

To get 'h' I would tap the ghi button twice, but it yields '44' instead.
I checked there is a language selected for predictive text. I really want to get this working without installing a third-party keyboard, as I did that before and the nature of my device's low internal memory really makes it difficult.
Running Android 2.3.6, Cyanogenmod Revolution Light build

What happens when you click the 123 button above the settings button. Does it change to abc?

If I press the 123 button the letters change to a numeric keypad, 0 to 9.

Where you were enter web or app, what ever use this type of keyboard exclusively just to let you write only number code or phone number. If you will enter other app (writing box) and try to write using the keyboard 3x4 you will be able to write alphabetic characters.

Battery draining much faster
I have rooted by Huawei Honor 3X using this procedure http://playfuldroid.com/how-to-root-huawei-honor-3x-tutorial/ , but it seems like my battery are draining slightly faster. Should I unroot my device, or could it be because of the live wall paper?

Rooting should not affect battery life, unless you have unlocked bootloader too and installed some mods/tweaks or whole custom ROM. You can check the apps with root access, if they're not causing the problem.

Tab 2 recovering data from hung device
Samsung Galaxy Tab 2 stuck on logo screen during reboot. I did go through several threads on this and other sites, and pretty much all of them suggested a factory reset, and not a single one said it was possible to recover data later. (I beg your indulgence and patience.)
I did make the cardinal mistake of not backing up my data. I'm new to tablets, Android, everything.
Recovering some of my contacts, notes and photos is as important to me (if not more) as being able to use my device again.
Does it make any sense to try and wipe the cache only, and do a reboot?
OR
If I do a factory reset, I gather only /data is wiped. Is there a chance I can recover some files from /cache later?
Which one do I need to try (first)?
There is also a software called Android Data Recovery, which claims to have had success in post-reset data recovery. Any thoughts on this?

Also, is there anything else I can try, before doing a factory reset? Will a cache wipe help? Or any other steps?

Firstly, data on your SD card will not be erased. Then there's a chance, that your contacts are already backed up on Google's servers, so you don't loose them either.
I don't know if the app will help. Harddrives don't delete anything, they just stop indexing the files and then rewrite the sector with new files, but (I'm not 100% sure) I don't think you can do the same with SD memory.

Will disabling LTE extend my battery life even if I'm not using it?
I was just wondering, if disabling LTE will improve my battery life even if I'm never using it (there's no LTE in my country).

It might marginally increase your battery life, since if the network selection is set to Auto, it will periodically poll the networks to see if LTE is available. Since it won't find it anyway, why not disable it and restrict it to your available networks?

Thank you, I thought it but wanted to make sure.

Facebook on Nexus 4 looks different than on Nexus 5
I have a Nexus 4 and Facebook looks like the picture on the left; while on my Nexus 5, it looks amazing, like the picture on the right (with fixed tap and native Android version):

I tried re-installing the application and changing the device language with no luck. How can I get the Nexus 5 version?

It is called A/B testing. It is a part of Facebook test and targets few users. You cannot get that version, its Facebook who controls which user gets that and its basically random.

It is the new Facebook app design. You don't choose to have it and it is not tied to a apk, but rather to your account. At a certain time, when you connect your account on a device and if your account has the new design, the app will switch itself to its design, but not instantaneously.

My facebook account is already using the latest design for weeks now. However, the facebook on my nexus looks the old one.

How can I make navigation work again in Google Maps?
Device: Samsung Galaxy S2
For quite some time, I've been using Google Maps and Navigation. It worked fine with several app updates, until this week. Google Maps updated, and now Navigation crashes as soon as it actually needs to navigate.
At one moment I really needed it, as I was having a business appointment. You can imagine how disappointed I became.
How do I fix this, aside from using a different navigation app?

If you haven't already, you should report the crash to Google by clicking "Report" when you get the "has stopped" dialog. If they don't know it happens, they can't fix it.

Can you describe the problem in more detail?

Quick fix is Settings-> apps-> all apps-> google maps-> uninstall update

As of this answer Google maps navigation is working fine. I have used it without incident. Also street view is working much better.
We'll see how future updates hold up for navigation.

Can you unlock brand new phones?
I saw a cheap Verizon HTC ONE M8 on eBay, but I am on AT&T. If I was to get that phone, could I unlock it straight away? I thought I remember hearing somewhere that you can't unlock phones for a few months after their release.
Sorry if this is the wrong site to ask.

You can unlock phones a few ways: 1) buy an unlocked phone 2) unlock via 3rd party software that will more than likely result in a voided warranty 3) wait for carrier commitment to be up and then ask them to unlock.  The thing with trying to unlock phones from different carriers though, is that Verizon is CDMA and ATT is GSM.  So with that, you can unlock the phone yes, but whether it will work on ATT (be it at all or how well) is up to you. My guess is that voice/text will work fine, but you will not get any data until you edit the APN and then it's up in the air.

Phone screen went black after getting wet and will not turn on

It's not quite a duplicate, but the answers on this question should help you out.

Dont charge the phone right now! You'll fry it!

Most of the advice I've seen for a drenched phone (of any stripe) is to immediately turn it off, remove the battery, bury it in some uncooked rice for several days, and pray. If, after three or four days, if it won't take a charge or turn on, it's time for a new phone.

How can I make my Galaxy Tab 3 authenticate with my Sky Router?
I have just tried to connect my Samsung Galaxy Tab 3 (8") to a Sky Netgear Router.
In the black bar at the top the WiFi icon has a question mark in it. On the Settings page, in Wi-Fi, it alternates between:
Wi-Fi networks Connecting...
SKY00000
Authenticating...

and
Wi-Fi networks
SKY00000
Saved, Secured

I wondered if it could be the router but didn't have time to investigate. I've just arrived at another house with the same router type and I'm seeing the same thing. Neither router had been played with. I'm using my phone to submit this via the router, so it's working fine.
The Tab 3 is new and I'm not at all familiar with Android. Is there anything on it I can tweak?

The next day, when I powered up my Tab 3, it just worked.

Sim Problem After installing custom rom
I have qmobile Noir A600 It has same specifications Of canvas a116 As We do t have any cuatom rom So i installed ro.s of canvas But now sim is not detected every thing is working fine...Is there is any solution?

It is never a good idea to flash a ROM that is not for a specific device onto a device.  With that being said, there are multiple reasons (i.e. different memory locations for the SIM circuit, different microcontroller, etc) that could be causing your issue.  My advise is to reflash the stock ROM and see if that fixes your problem.  If so then PLEASE do not flash a ROM that is not for your device.  It is to the point now (say with the HTC One M7) that you won't receive signal if you flash a ROM of a different carrier even.

Move apps and games in Sony Xperia M to SD card
How can I move apps and games in sony Xperia M? There is no Move to SD card option.

To move my apps and games to my SD card I use the app AppMgrIII. I have had no issues so far.

A description and a use-case would definitely help since the answer, as of now, is not much worth without the link.

If you have a rooted phone and a updated version of CM, I believe that in Settings -> Apps-> (on SD card) you will find a list with check-boxes.
But if you don't have CM, well, I recommend the app: AppMgr III (App 2 SD).
