Increase phone speed
My phone is sometimes freezed. I have installed and configured Clean Master and Battery Doctor, but it still slow. My Phone is Huawei Y300, running Android 4.1. What can I do for speed up the system?
Buying another phone is not an option

That phone has a fairly low-end spec sheet (Cortex-A5 processor, 512 MB of RAM). There's only so much power you can get out of any given set of hardware so you may simply be hitting the limits of it.

if you have root you can have a swap memory using sd card.Make sure you have at least class 8 sd card for fast performance. It's an extension memory to store  all your cache to make up your ram free and run the device somewhat fast.You can use apps like "simple root swap".And remove apps like Cleanmaster and Battery-doctor they use memory in backend and slows your device. if you have root apply kernel level tweaks for a little boost-up.

I uninstalled those programs... I will try swap apps. Which are kernel level tweaks? How do I apply those?

Is there a way to use a phone as a virtual keychain for NFC tags?
So let's say I have a bunch of things that can be unlocked via NFC. Each thing would correspond with one tag and one tag only. The problem would then be that I'd have to carry a bunch of tags around. What would make this much more easy to manage, would be to use a phone as a keychain for these tags. A keychain in the sense that all tags would be virtually stored on the phone. When I then would need to use a tag to unlock its corresponding thing, I'd need to emulate the tag through the phone.
The question is then: is there a method available to store multiple virtual NFC tags on the phone, and can the phone in turn act as a tag emulator?
P.S. My current phone doesn't support NFC, but my near-future phone will (and it will of course have the latest Android version that's available at that time).

Add a new laguage (Bengali) in my Huawei Honor 3C phone not having this language
How to add a new language "Bengali of India" in my Huawei Honor 3C phone not having this language.
I have checked SETTINGS -> Language / Input and my language is not listed here.
I saw Samsung Phones has Bengali Language in Languages List as I have Samsung Tab311.
So how to add this new language in my honor 3C Android Phone 4.2.2 JellyBeans

Related http://android.stackexchange.com/questions/83503

Bengali is only available as a system language starting with Android 5.0.0 Lollipop. So you can't add it as a  system language ( I don't know about options with root). However, you can configure Bengali input using a custom keyboard option such as Google Keyboard or Swiftkey Keyboard. These have a "Languages" option for adding languages.

Reset Galaxy tab without losing apps in SD Card
I have an old Samsung Galaxy Tab, it keeps on lagging and has delays. I want to reset it, if I do will the newly reset Tab still acknowledge the apps stored in the SD Card? Thank you.

I just flashed a new ROM to my Galaxy Tab 1 last week and the data on the external SD card was intact. Please clarify what you mean by "apps" stored in the SD card? Do you mean apps that are "moved" to SD card, or do you mean app data or app backups?

Short answer
No.
Explanation
One purpose of a reset, and why it's called factory-reset, is to set it back to the state it came from the factory. This means, all user apps and user data is "removed" (de facto, /data and /cache are wiped). Usually, only internal storage is affected this way, and SD cards are left untouched unless explicitly specified (I write "usually" as some manufacturers/ROMs deviate from this).
That said: your "apps on SD card" will be gone even without the SD card being touched, as:

app2sd doesn't move the entire app to SD card (but only parts)
Android would forget about those apps anyway, as information on packages installed resides in /data/system/packages.xml – and you remember, /data gets wiped by the factory-reset.

+1, I believe /data/system/packages.xmlshould've been a teaser for Short Answer.

@Firelord that would make the "short answer" 5 (or more) times longer :)

Making a custom upgrade ROM
Is it possible to make a custom ROM to upgrade the current version of android that is installed on your phone?
For example, making a 5.1 ROM to put on an pretty much unsupported phone that only has 4.4.2.
I've seen many posts on how to port ROMs between devices, or making your own custom ROM, but all of the ones I've seen require you to stay on the same version of android.
I'm just wondering if I can take a stock ROM, or a cm 12.1 rom or something and port it onto my device. (Which is a LGD393 in case that helps).

Firstly . It is possible to make a custom ROM to upgrade the current version of android that is installed on your phone
Secondly you can't port roms of other devices to your phone . But  you can take the stock rom of your device and make some modifications to upgrade the version of android.
For custom rom development refer here.
http://forum.xda-developers.com/showthread.php?t=2069130

your second paragraph is incorrect. That is exactly what porting a rom is from one device to another. To be successful the devices need to be similar. http://en.miui.com/thread-14502-1-1.html  http://forum.xda-developers.com/showthread.php?t=2370873

Well, it should be possible to port any version of android to any phone (with some hardware limitations, of course) since AOSP is written for Nexus phones, and OEMs take that and port it to all of their devices.
So, I guess I answered my own question there.... but I have no idea where to even start learning how to do all of that. The custom ROM guide I'm pretty sure is for porting similar versions of android (4.4 -> 4.4) and has nothing for porting to new versions. (4.4 -> 5.1)

Deleting Pictures- Will They Really Be Gone?
Lets say I were to delete a photo, is there any way possible this photo may be seen on this device ever again? Will anyone ever be able to see this deleted photo if they pull up my device on their computer or laptop? If I delete a photo am I going to have full reassurance that this photo will never be seen again?

It can be retrieved from the external SDcard using recovery tools.

There are lots of other points consider. Each of these cases provide a means to retrieve:
In ES file explorer app, there is a concept of recycle bin. If this is enabled, the deleted photo can be retrieved by visiting the recycle bin section. If the photo is not deleted by this app, this point will not apply.
The apps like Google Photos, OneDrive etc have an option to upload the photo to a cloud services. Deleting a photo might not delete in the cloud. If you do not have these apps installed or installaed, but configured to ignore the folder from which you deleted the photo, then the photo can't be found in the cloud.
And the last bit is if the photo is stored in an external storage, then it can be removed and mounted on a card reader in a computer and there are apps to recover. It is not assured recovery, but chances are there. If your device is rooted, there is an android app to undelete the photo as well.

Create new image file of 750 x 380 px on Android phone
I need to create a blank 750 x 380px image on my android phone - then paste some images and text onto the blank image. Simple as this sounds - spent over 72 hours searching the Web with no way to this. Pixlr and all other mobile image editing apps can only edit existing images - but won't allow you create new ones with fixed canvas size. Suffice it to say I haven't got access to a computer now and must do this on my Samsung android mobile. Help guys - I'm about to really really freak out.

First- don't freak out. That would be silly.
Second- we are all using Android devices, which means that Google Search is built in and pretty simple to use.
See the answer below.

Don't freak out. That would be silly.
I just tried (for your question) an app named PhotoSuite 4 Free. I was able to start a new project, specify its pixel dimensions and add a text layer. Seems to be what you're looking for.

Stock LG-D500 Bootloop. Factory Reset only temporarily fixes
I checked a few of the other links/threads. Mostly it seems like people changed something (ROM, or went in a did something to permissions) whereas my phone has no changes made by me. There are/were apps on the phone.
The phone started acting up awhile ago with lagging (if this is relevant) and I would have to restart it every couple days.
Now the apps are crashing and I wasn't able to open almost anything. Like Alarm Clock, Google Search, BaconReader, etc. I was able to open Pandora. When I tried to restart it it went into bootloop. I tried to fix it myself by searching Google and Factory Reset and Wipe dalvik-cache seemed to be the answer, however I could not for the life of me find Wipe dalvik-cache on the LG-D500. I did a factory reset and that let the phone turn back on. However soon the same apps were crashing and the non opening issue was back. Even System UI crashed on the last reset attempt.
If I hold power and down volume it only goes to factory reset. I can't figure out how to wipe the cache or anything like that.
Apps (now they are gone due to reset)

BaconReader
Candy and Soda Crush
CM Lock, Cleaner
Pandora
Moon Reader+
Chess.com

What can I do? Any help is greatly appreciated!
Thanks!

Manually Rooting with AOSP
this is my first post here. I hope there is someone to answer my question.
First, I want to understand Android OS better not just copy some files and be finished.
I am attempting to root my Nexus 6 beginning with compiling Android for it. I was able to compile and upload all necessary images. Now I would like to root the AOSP configuration for shamu.
Currently I am able to access ADB root by replacing the boot.img with root access but how do I do a proper Android Root and not ADB root.
SuperSu: How to install it properly from ADB for Nexus 6 and which version!
Thanks in advance!

Generally speaking, you want the appropriate su binary to be executable from the PATH, such as putting it in /system/xbin.  What version you use is up to you, but if you're using SuperSU then use the binary that comes in its flash package (https://download.chainfire.eu/396/supersu/).

Thank you but do you know which is the proper version of SuperSu for Android 5.1.1?

@Orri The latest should work just fine.

Mirror android screen on a spare lcd monitor using usb cable
Can I connect my smartphone running Android 4.2.2 to a spare dell lcd monitor by using a mini usb cable so I can mirror the android screen onto the monitor? Is it possible? Using some app maybe? No desktop is involved. Just a spare lcd.

Does your monitor have a usb-input which is possible to use as video input? I don't think so.

You need to be much more specific about the phone and monitor. Model numbers would be helpful. Information and photos of the connections on the monitor would also be helpful. More info, please!

if your device have MHL capabilities you try buying the cable mentioned in this video https://www.youtube.com/watch?v=XDS6cP-ViG8

check out this website for more details on mhl https://gadgetstouse.com/blog/2013/08/24/mhl/

Original answer from September 2015:
No, you cannot with a standard USB cable. Depending on the mobile device in question as well as the monitor, you could possibly connect the phone with an MHL adapter.
Update September 2020:
Five years later and, of course, there are greater options for connecting a mobile device to an external screen. Hoping that everyone is now running newer than Android 4.2.2. and with the use of USB-C for connections, I've been using this USB-C to HDMI with OTG USB-A and USB-C charging. The important part is the charging feature for two reasons:

Some devices will not transmit video without additional power.

The adapter will charge the device while it is being used to drive
an external screen.

Is blocking ads with hosts file slow?
For instance, Adaway offers a hosts file with 300K addresses to block.
It works, but will this significantly impact performance, therefor battery life? When does the system access the hosts file? Every time a connection is made, or is it just read once at system restart and stored in memory?

Normally, it is read once and remains in the memory. Do you have any statistics or any proof to even suspect that that file would impact performance or battery life at all?

Is it possible to connect a device to a pc so the pc display is on the device's screen?
Well the thing is i broke my pc monitor so is it possible to connect  it using an hdmi so the display is on the device screen?

What device do you have?

Samsung note 3 android

VNC should be the answer.
From Wikipedia:

Virtual Network Computing (VNC) is a graphical desktop-sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It transmits the keyboard and mouse events from one computer to another, relaying the graphical-screen updates back in the other direction, over a network.

With VNC, you can control another computer or a group of computers available on a local network.
The procedure is as follows:
Install Real VNC server on your computer, and Real VNC viewer on your Android tablet. Your computer and Android tablet should be connected to the same network; if you don't have a WiFi connection, you can use your mobile WiFi hotspot or USB tethering to connect your computer for which you needn't require mobile data pack.
For your HDMI solution, I believe your tablet support OTG functionality. Buy HDMI adapter and an OTG cable. I believe it should do the job.
I fear the HDMI streaming could go opposite, so VNC should be your choice as HDMI would drain the battery and you won't be able to charge your tablet in between.

Broken screen and touch
I have a HTC One M7 and long story short the screen is completely destroyed but the phone still works because i still get beeps and LED blinks when someone messeges me. I would like to get my pictures and contacts off of it but when i try i have to unlock the phone to get a access to the files and the touch screen is broken so that isnt possible. Also i cant see whats happening on the screen which makes the situation even worse. Can someone please help me get my files off without having to physically put in the pattern. Please and thank you.

Welcome to the Android Enthusiasts! Have you already checked with our broken-screen tag-wiki? Several hints and first-aid there. If you've checked already, what did you try and where are you stuck?

If you have rooted your phone you can try to use android control. It allows you to see the screen and touch the screen through ADB but it is a bit hard to get working sometimes.
If you can see the screen you can try an USB OTG cable with a USB mouse attached to it. I had this for a week when my touch broke down physically, people tend to look at you weird with this but it works quite well.

GS4 not turning on, battery full, no screen activity or rumble
(Keyboard finicky, sorry for any errors!)
Alright, so I have this GS4 that I got secondhand. It worked fine for a while, but now there is no activity AT ALL. I have tried Recovery Mode, normal boot, and Odin. I don't even get a RUMBLE. It's fully charged, so that's not the problem...
Most of my personal data is on the phone itself (1 GB MicroSD card... >_>) and most of it is important.
Any help?

I'm not allowed to comment...but I ran into this same problem on my Galaxy Note 2. It was fully charged but I couldn't do anything at all, screen never even pretended to light up. Samsung had a bad batch of hardware causing a "Sudden Death Syndrome" as people were calling it. The one thing I did notice was that if you look at the area where the proximity sensor lies, you can see the little "infrared" light stuck on. Is that the same for you? Here's an XDA article related to the problem:
http://forum.xda-developers.com/showthread.php?t=2294203
If the phone is still under some sort of warranty, you should be able to get a new device.

Sorry, but it's been rooted. And I checked for SDS, and nada. No proximity light either.

Firefox in cache slowing down phone
I am running Cyanogenmod on my rather old Motorola Droid 4, and it is pretty slow by now. I something quite strange lately. From what I read on the internet Android seems to handle memory quite differently than Windows or a regular Linux would. From what I understand it keeps apps that I closed or put into the background in the memory so they start up faster. This can be observed when going to Settings->Apps->Active->Apps in Cache. Apps in the cache should not be really running and should get cleared out as soon as active apps require the storage. But when I have Firefox in cache this doesn't seem to work. Firefox uses quite a lot of memory (top tells me it's using around 800mb, while Android still reports some 150-300mb, my phone has 1GB RAM total) and while it is in cache the whole phone slows to a crawl. Top tells me, that my CPU is hardly used, so it looks just like heavy swapping.
If I kill Firefox my phone instantly speeds up.
I checked using busybox free that I don't have swapping enabled.
Does anyone know the reason behind that or even a way to fix that issue?

Resolving Credential storage issue
On Samsung Galaxy Note 10.1 SMP600 when I try to to add a VPN I'm prompted for credential storage password. I have tried all the other solutions on SO and none of them worked. I have PIN code on the lock screen as well and I cannot clear the password as the option to do so is greyed out.
I talked to Samsung and they eventually told me I had to factory reset of the tablet! I want to know how to fix this once and for all. My device is rooted running stock ROM Kitkat 4.4.2.

This is a non-conventional solution (which might/might-not work for everyone) but can be helpful to others having the same issue.
Answer gathered from androidforum and google product forum
What we are trying to achieve is to Set-up a pin and fail to enter it deliberately to access recovery using  gmail address and entering the VPN settings directly after google sign-in.

Steps to achieve this:

Add a pattern lock and other information that goes with setting up a pattern-lock recovery.
Reboot phone and when the screen presents itself asking for lock pattern enter 5 failed attempts.
When theprompts says to wait 30 seconds, press OK and find the recovery button where you enter google account info.
After signing-in go straight to VPN settings and enter a new pattern-lock/pin.

If the above mentioned steps does not solve your issue go ahead with the alternative method.
Alternatively you can make use of 3rd party app called QuickShortcutMaker and follow the steps as mentioned here

Sharath, I'm afraid this doesn't answer the question: OP didn't ask for a list of VPN apps (which would have been off-topic) – but about solving the issue with credential storage. Could you [edit] your post and fix that (before downvotes come hailing down on you)?

@Izzy thank you for letting me know. Edited now.  My bad, I thought it was a software rec post.

Yupp. Hint: SR=blue-favicon, ASE=green-favicon :) Or in my case, I take a look at the rep in the SE „MultiCollider™“ bar #D

@Izzy Thanks for the tip, I'll keep that i mind. Also good tool, Multicolloder and also IzzyonDroid ;)

I have tried both of these methods before and even retried them now,  however neither of them work for me. Whenever I get the open VPN stage I'm  prompted for credential storage.

@preezzzy Did you try setting up a new pin in credential storage?

@Sharath The only place to set up a new pin is Device->Lock screen->Screen lock. I'm not sure what you mean by setting pin in credential storage. I followed your instructions until Step 4. When I go straight to VPN it doesn't ask me to set up a new pin it asks me "Enter password for credential storage".

Disable "Search apps..." search bar
Device: Moto G 2nd gen (Android 5.0.2).

See picture:
Does anyone know how to revert the situation?

Which launcher is it? Is it Google Now Launcher? I've heard that they recently introduced the vertical layout.

Related http://android.stackexchange.com/a/124205/119358

If you didn't do anything then atleast you must have the default auto-update setting in your Play Store app. So it has updated to the newest version available on Play Store. As it appears on the Play-store comments its the Google App that has been updated to version 5.3 and the UI of the app drawer has been updated from horizontal menu to vertical scrolling along with the search bar at the top in the latest version. You can simple try a different laucher like Apex, Nova for a quick solution. If you don't like other launchers you can try uninstalling the Google app's updates in the Settings.

Shell with su cannot remount /sytstem. adb can.
I am trying to mount the /system file partition in Android as rw. I have ro.insecure=0 in my default.prop. I have su installed and working correctly.
I can remount the file system using 'adb remount'
However, when I am in a shell prompt, I get a 'permission denied' error whenever I try to remount the partition.
Why would adb remount work but remounting as root user in a shell not work?
I am using
mount -o remount,rw /system

I have also tried
mount -o remount,rw -t ext4 /system

but to no avail.
My default.prop has the following:
ro.secure=0
ro.debuggable=1
persist.sys.usb.config=adb
ro.adb.secure=0

How did you root and how do you know it is working?  If you're using SuperSU, trying turning off the "Root namespace separation" option.

The ROM is pre-rooted and I can install root applications. The shell gives me root access and the daemonsu process is running. I am using Superuser not SuperSU so I don't have that option.

I edited the fstab in the ROM and set it to rw. This is dirty but it works nonetheless.

ifconfig eth0 [IP] netmask [masque] up

It works, but these changes are removed after a reboot. It's a big problem in my case. I tried some solutions like edit the init.sh, or third party app on the store, but neither works.
What should I do ? Am I missing something ?

I did it, editing the file /etc/init.sh did the trick for me.
just adding at the end :
ifconfig eth0 [IP] netmask [masque] up

It should be ran at boot.

but what if it says "unknows id" to ifconfig?

I would love to help you but I can't remember anything about this, it was some little internship project. Sorry !

ifconfig eth0 [IP] doesn't seem to work in Android x86 7.1

/etc/init.sh isn't a universal solution, very ROM-specific.

what does it exactly mean to move data in phone storage and internal storage
I am using a Micromax canvas turbo
it has 16 GB internal memory
so when I install an app ,
i get the option to move the app to internal memory card ,
and then ican move it back to phon storage
so what exactly does these both mean ,
how should we decide ,
what app to move ,
or any info regarding this movement

"Phone storage" is essentially your /data partition, the main space on your phone allocated to apps.
"Internal storage" sometimes means the same but, since they are being contrasted here, it likely refers to the internal "SD card" partition.  Likely both of them are on the same flash chip, just set up differently.
SD cards (and "cards") are sometimes mounted later in the boot process, so sometimes it can confuse some launchers and you end up with app shortcuts being removed from your home screen.  Services also might not start properly.  Otherwise, however, they are more or less the same.  You really only need to move apps around if you're running out of space or if you want to be able to wipe one partition without losing as much data.

Returned One M8 to stock but can't install OTAs
My UK EE One M8 was unlocked, rooted and running a custom ROM.  The CID is ORANG001.
I wanted to return it to stock so installed stock recovery and a stock ORANG001 nandroid, relocked the bootloader and returned to S-ON.

It all looks OK but when I start receivng the OTAs, I get this error.
We have determined that your phone may be running a modified version of it's system software.
What have I missed?

Are you sure there's been no modifications to the system partition? You should double check.

@keepcalm Sorry, that's a bit above my knowledge level.  How can I check?  What do I do if it is modified?  Cheers

Are you sure the nandroid you restored is completely stock (no leftover root or anything)? It's been a while since I used an HTC so I might be a bit rusty, but have you tried using a different Nandroid (maybe one of the ones here), or manually applying one of the OTAs in that thread?

How do I see if my Android Nexus received the latest security updates?
I'd like to check the patch level of my Nexus. I'm using Lollipop 5.1.1 build LMY48I. Under 'System updates' in 'About phone', it says 'Your system is up to date'. Should I assume that includes security updates?

In Marshmallow (Android 6.0) there will be an additional bit of information on the 'About' screen showing the "Android security patch level". This should show the date of the last security update that your phone has. How you will know that this is the latest available is unclear though.
Source
As for pre-Marshmallow the best suggestion I have is to look at the factory images page and see what the latest build number is for your device. Depending on which device you have there should be a newer version than LMY48I, most likely build LMY48M.

The Build number, e.g. LMY48I (found in 'About phone') can be looked up in the Android Security Updates list, or the list of Android factory images.
In this case you can see LMY48I refers to the August 2015 security update, but there has been another update since then: LMY48M for September.

If you mean the Android Device Protection (ADP), then according to Google,

applies only to devices running Android 5.1 or higher that came
  preinstalled with Android 5.0 or higher, such as Nexus 6 and Nexus 9.

References ..here and here.

No, not for the anti-theft. Google started pushing out monthly security updates this year.

My bad, according to Google, this update was made to patch the Stagefright exploit, and if you want to check if your device vulnerable or not, then you can use one of this apps, 1. Stagefright Detector ( https://play.google.com/store/apps/details?id=com.zimperium.stagefrightdetector ), 2. Stagefright Detector ( https://play.google.com/store/apps/details?id=com.lookout.stagefrightdetector&hl=de ), everything you need to know about Stagefright in this article ( https://www.androidpit.com/what-is-stagefright-on-android-am-i-affected-and-what-can-i-do ).

Cheers. I was hoping for an easier way to check for future security updates as well.

Loding file on recovery mod
I really need to know how to load .zip files on the recovery TWRP. Because I did a system wipe without previously do a flash of the new ROM. There's a way to put the ROM on the phone even without any system on it? Thanks.

Look into adb sideload.

Loading and flashing a ROM from within TWRP can be done with a few easy steps.

Select a ROM and download it to a place on your computer with a simple path such as a folder on your desktop.
Open into TWRP and plug your device into your computer.
Open the terminal with administrative rights and verify your device is visible with the command adb devices if your device is present it will show up.
Next throw the command adb push path_of_the.zip /sdcard/ that should put the ROM.zip in your sdcard.
Within TWRP click the install button and navigate to where the ROM.zip file is. In this case it's in the /sdcard and click it then slide the bar

Phone: Galaxy Note 2; I605 (Verizon- Unlocked)
Carrier: T-Mobile
Rooted: Yes

I have this problem with Android Lollipop where when I cancel a call, the hangup button disappears and the phone says "Hanging Up" but never hangs up. Navigating away from the dialer screen destroys the UI but the calling process still runs in the background to the point where it either goes to voicemail if the other party doesn't pick up or hangs up in case of interactive calls.
This only happens with Android 5.x.x. What could be the problem? Has anybody encountered this and what was your solution? Thanks.

Make sure your system applications are updated in the play store. the store will contain the latest updates which might have the bug fixes for the above issue.
Android lollipop would have the notification type alert. are you getting it properly? is it possible to hang up the call there?
If still problem persists, then wipe partition cache might solve the issue.

Actually this was a different problem. I used an At&T ROM on a VZ phone which surprisingly has the required libraries and the problem went away.

Why are some of my pictures all black?
I was out on a hike today and took a few pictures. When taking a picture I saw the usual animation where I see snapshot of the picture just taken, and then it slides away from the screen to display the camera viewfinder again. After coming home I notice this in my google photos:
What causes this to happen?

Any chance your finger was over the lens?

This happens to me when the camera accidentally gets activated in my pocket.

Are there any photos you made but there are not here?

It appears as if this is an issue where the camera got activated in a dark place, such as your pocket. Undue pressure (false touches) can cause this, or even if the camera app took 2 pictures in burst mode (it isn't supposed to happen, but it does anyway). There can also be other issues which may rarely be for to a hardware problem, but since this is not a major problem I don't think it merits a service center visit.

Google Play say "You dont have any device"
I've just bought Ewing I960 android tablet. strangely this device does not come with google play store. So I try to install directly from google play site.
But could not install any of the android apps. Got this message from google when installing the apps. So not apps can be install.
I did download latest google play apk. It got installed but fail when opening the apps.
Hope I can get some light on how to resolve this.
thank you.
ag.

See if you are logged in with the same Google account that you used on your tablet

Looks like your device is not supported by Google (list of devices that support Google Play). Anyway, you can try to find GApps - Google applications that come pre-installed with most of devices. In your case they must be installed via recovery.

Turn screen off without Android sleeping
Is there any way to quickly toggle the screen off without making Android sleep?
For example, I sometimes like to use the Calm app when I sleep.  But it keeps the screen on all the time.  When I just use that app for 10 minutes, it's great that it keeps the screen on; but if I'm sleeping for hours, I would like the app to keep on running (playing sounds) and turn the screen off.
How can this be done?

For this the app needs to explicitly create a so-called "Wakelock" that prevents Android to set the CPU into Deep Sleep and keeps the whole system (including your app) running.

@GiantTree Right. Is there a way to quickly toggle that on/off for all apps or a specific app?

AFAIK an app has to ask for such a wakelock on its own. Otherwise Android may just kill an app if it is running in the background without a lock.

I probably didn't understand the question. Can you not press the power button and let the screen turn off? If yes, does your app stops working? If true, this answer may be of some service: Is there a way to force an app to remain running in the background no matter what?

@Firelord  If you run the Calm app and don't press the power button, the screen will never turn off.  After hours of sleep, I was happy that the screen image was not burned in.

Changing /sys/class/leds/lcd-backlight/brightness  to 0 does the job in my device. It doesn't put the device to sleep, but simply turn off the LEDs. Tested on that Calm app. You can hear its music yet not burning up the battery on screen. Requires root access though.

@Firelord If it turns off the screen, how do you change the value back (since you can't see anything)?

Press the power button two times with gap of one second, the screen would come back to normal. I tried it over ADB so I could always change the value. You may bind this behavior to a button using Xposed Additions. Or perhaps a time based event in Tasker could also be an option.

@Firelord Thanks... I'll give it a try to see how it works.  Is there a way to edit the file automatically?  Going in with a root editor and changing the contents of the file each time is a bit laborious.

Automation app like Tasker can do it. Task would be + -> File -> Write file -> your content. Or, + -> Code -> Run Shell -> and write the file using command.

I had some trouble with the accepted answer as I'm not hugely familiar with shell scripting on Android/Unix/Linux so I thought I'd add my experience here for anyone in a similar boat.
To get this working with Tasker or similar the line you need is:
echo 0 > /sys/class/leds/lcd-backlight/brightness

For tasker put this in the 'command' field with 'Use Root' enabled, works like a charm. To disable simply switch the zero out for a 1, ergo:
echo 1 > /sys/class/leds/lcd-backlight/brightness

or lock and unlock the device.
So to answer your question about quickly toggling this behavior. Assign each of the above commands to a tasker task, then you can make use of the new long-press intercept in the latest tasker version to toggle the screen on and off without putting the device to sleep. Alternatively you can assign the command to a profile which triggers when your conditions are met.

adb devices gives same serial number for all Micromax devices
I have few micromax devices and I have different serial number for those in the box. But when I run the command adb devices for these devices, I get everything as 0123456789ABCDEF. Is there are way to get the proper device serial number for these micromax devices?

What do you mean by Serial number? I mean are you referring to IMEI?

The number that we see when we run "adb devices". The same number can be seen in the box in most of the other phones as "S/n". Ideally they both should be same.

You can try this: https://android.stackexchange.com/questions/209020/serial-number-got-changed-after-factory-reset

your problem may be incorrect drivers. if you installed correct drivers then restart adb and your phone too. if this does not help im sure you're not installed correct drivers. hope this help.

Nexus 7 2013 is permanently awake
Note: I do not mean screen-on state, but awake state.
My Nexus 7 is permanently awake. It is not rooted, so I could not easily check for wakelocks. I did try the method to run wakelock detector on a non-rooted device, however, and it started working for a moment, until I restarted Nexus. While it was working, it showed a 97% Awake state for a day or two of running.
However, the wakelocks were minimalistic. At first, there was Any.do showing some good amount of holding awake state, but it was far from permanent wakelock. In a moment however the top 3 wakelock holders disappeared and only minimalistic wakelocks stayed. The minutes of awake state of the wakelocks shown would not add up nearly up to an hour of awake state, whereas the device was awake for more then 24 hours already.
Android system processes were shown too.
Do you know what could be causing a permanent awake state of the device? Can I do anything about it other than rooting the device? Towelroot is not working and I know of no other rooting method that would not leave my device flashed to the factory state (do not wanna lose state of the device).

not to pry but did you check you display settings. If that is OK then try to boot into safe mode and see if the problem persists. If yes then the OS is buggy or something is related to the OS of your nexus. If the answer is no for the safe mode then the problem definitely is because of some app.

Display settings? Just to clarify once again - the screen is off. The device appears off. This is not a display issue, but a CPU awake issue.

still the safe mode thing holds. Have you tried it

Need to upgrade from Android ver. 4.4.4 to Android ver. 5.0 with unlocked bootloader
I have an Xperia Z and recently I unlocked the bootloader. However now I cannot install (upgrade) to the Lollipop Android 5.0 (10.6.A.0.454) from Android 4 (10.5.1.A.0.292) through the Sony website. I always get the message "cannot be installed because I have an unlocked bootloader".
Please advise on a step by step process to lock the bootloader again if possible or advise on how to upgrade to 5 version.
Please make it for dummies because I am not experienced or a developer whatsoever.

Actually it's possible to relock the bootloader, using Flashtool. The process can be found on this XDA Forum post.

Download Flashtool from www.flashtool.net
Start Flashtool and click on BLU button
You will be asked to connect device in flash mode
Once you connect the device you will get a prompt to "Relock"
Click on it and when prompted disconnect the device

You should download the custom version of the ROM from some trusted source and then flash it from your boot loader.
Don't forget to take backup of your current configurations. And I recommend you to install some custom recovery as well (like teamwin recovery).
NOTE: Before using this method, take backup of your device.

Note that this will require you to clear your data from the device.

Of course this will. You will have to take backup of your device.

How to check if bootloader is unlocked mediatek device
My Device: Rooted Karbonn A52+ Android 4.2.2 (Stock ROM) | MTK6572 CPU
Hi friends, I was recently able to flash Clockwork Mod Custom Recovery followed by a Custom ROM flash from the recovery (though now I've re-shifted to the stock ROM). But, what is suspicious is: I NEVER UNLOCKED MY BOOTLOADER! And it's obvious for most/all android devices that neither a custom recovery nor a custom ROM can be flashed without unlocking the bootloader. I didn't flash the recovery through the command

fastboot flash recovery recovery.img

but I flashed it through an app available on the play store called "Mobile Uncle MTK Tools". It successfully replaced my phone's stock recovery with the CWM Recovery.
Now, I could assume that this app itself unlocked my bootloader before flashing the recovery, but now the question comes "Then why didn't I face a reset of my device? I didn't lose any data!"
So I wanted to ask if there's any way to check out whether my bootloader is unlocked or not. Thanks in advance..

If I'm right, most Mediatek phones over in India come with unlocked bootloaders. I own a Karbonn Titanium S5+, and found it unlocked from the beginning. I used fastboot flash recovery  and it worked out fine, without the need of fastboot oem unlock.

That's great.. Anyhow, so there isn't any way to "verify" it?

Not sure, but flashing CWM requires the bootloader to be unlocked usually, so I guess that's proof enough.

There is a great deal of ambiguity and misinformation in the previous answer(s) above. The root cause of this is ambiguity inherent in the words "flash" and "flashing": some people use a "flash tool" to "flash" .img or .bin files, others use a "custom recovery" to "flash" a .zip file, and still others use the bootloader to "flash" a .zip file.
Mobile Uncle MTK Tools (mentioned above) is software used with .img and .bin files, but there are others such as the so-called SP-Flash-Tools (SmartPhone Flash Tool). These tools are typically Windows, mac, and/or Linux programs. (and btw the correct word in this case is "download," not "flash").
When using a recovery to flash an update, the code that does the work sits in the recovery partition itself, and the user controls the process via some sort of GUI on the phone that the recovery displays.
When using the bootloader to update the phone, there is a special-purpose client called fastboot that lives on a computer which is connected to the phone via USB. Fastboot is also the name of the protocol that this client speaks over USB  with the bootloader code on the phone.
With those three things understood, it's easy to see what's going on:

If you use a flash tool to download some .img or .bin file to the phone, then you don't use any code in the bootloader at all. So whatever it means for the bootloader to be "locked" or "unlocked" doesn't matter (since you're not using the bootloader)
If you are using fastboot and the bootloader, then unless the bootloader is UNLOCKED, you won't be able to install ANYTHING but a bona fide uncorrupted factory-approved update file. That's what it means for the bootloader to be locked -- if you tell such a bootloader "Fastboot flash mywacko-update.zip" or anything similar, you'll see an error message and failure. Because it's locked.
Now if you use a recovery to update the phone, you might think that we are back in the 1st case -- you're using the recovery and not the bootloader, so it shouldn't matter if the bootloader is locked or not. Although the logic is unassailable, the fact is that the stock recovery of any Android that ever lived contains code which will cause the update to fail unless the update is a stock factory-approved one. In other words, it's a fact that if the bootloader is locked, you won't be able to use the recovery to install something non-standard either.

But it's perfectly supported to take a flash tool and download a CUSTOM recovery which is not stock -- where one important feature of the custom recovery is that it just doesn't care about the locked/unlocked status of the bootloader.
If you do this, your custom recovery will "flash" anything you ask it to, .but you STILL won't be able to  use fastboot and he bootloader to flash anything non-stock. Because the bootloader will still be locked.
Finally, to answer the question about how to verify if the bootloader is locked or not:
Boot into the bootloader (sometimes called "fastboot mode"), connect the phone via USB to a computer that is running fastboot, and type the following command:

fastboot getvar all

If you're lucky, among the many lines of output you get will be ones such as:
(bootloader)    unlocked: no
(bootloader)    secure: yes
Strictly speaking, I believe that locked/unlocked just means that: it can not be changed. The bootloader is "secure" if it will only install factory-signed images. That being said, I have never seen any combination but two: unlocked and not secure // or locked and secure. (As a final comment, the value of the  "secure" is usually referred to as "s-on" or "s-off")

On my Karbonn A35, when I run fastboot getvar all, it gives a bunch of strings like ..partition-size.., ..partition-type.., etc. but not one line contains "lock". However, I know for a fact that the phone has issues with the fastboot flash commands and we have to flash using the SP Flash tool running on the Desktop.
The fastboot command just hangs when I try to flash the system partition. However, it does write other partitions like boot, recovery, etc. Does that mean it's bootloader is locked/unlocked?

I, personally, recommend Shareit

You could try Airdroid which allows you to transfer files from your device to your laptop(and vice versa) via Wi-Fi and then transfer them to your Nexus.

How to correctly identify your phone model and version?
I have a Samsung Galaxy Nexus and I'm trying to do a fresh reinstall of Cyanongenmod.
I see in their website that there are three different versions of this phone: https://wiki.cyanogenmod.org/w/Devices#vendor=%22Google%22;searchable=%22galaxy%22;
Now I am confused and don't know which version I have? I bought it in Portugal. But is there a way to automatically identify the phone?
Thank you

Download CPU-Z. It helps to correctly identify your phone model, among other features.

Link for the app, a brief description and optionally, a screenshot would help.

Go into settings then About Phone and it should display everything you need

From there I could only see that Cyanongenmod's version was implying that the phone was the maguro model. I'm not sure if that confirms that the phone is maguro as the first time I installed Cyanogenmod I might have done it wrong

Well, my assumtion is that the Cyanongenmod code get's the model using a GET command, so I'd say it was pretty accurate, I guess one way you can do it is type a model number into Google and see what model it comes up with

also what Gaurav said is a good path to take... tis a good, safe app!

Lollipop 5.1, completely safe from stagefright?
I am currently updating my Android phone (a Moto G) to Lollipop 5.1.  I previously had taken action to prevent Stagefright from happening to my phone (setting multimedia messages to only manual downloads).  The update said that Lollipop 5.1 included a fix for Stagefright.  I am wondering what this fix is and if my phone is now completely safe from Stagefright (i.e., I can set multimedia messages to automatic download again).

Probably yes. If it includes Google's August update, you should be free from Stagefright vulnerabilities.

You can use Zimperium's Stagefright Detector app to test your device for the known attack vectors. The bugs were not patched upstream until Android 5.1.1, but it is possible (particularly based on the change notes) that Motorola backported security fixes to their 5.1 release, so the version of Android you have is not necessarily the best indicator.
NB: One of Zimperium's researchers is Joshua Drake, who disclosed the Stagefright vulnerabilities to Google and submitted patches to fix them. It is therefore reasonable to conclude that the tests in their app are more than likely accurate.

It's not based on the version of Android you have. Because Stagefright is a core library in Android framework and was found to be known after Android 5.1 was released.
But it's based on OEM's releasing the patch for Stagefright. Motorola have been posting the updates in their forum that it will soon release a patch for its users and ways to mitigate the issue till you receive the updates. Since you have Motorola Moto G and YES, Motorola has officially released the patch for the security vulnerability known as "Stagefright"(in the libstagefright media framework) after Google reported to Motorola in the late June and as it has been mentioned in the Motorola forum that and its support website,

After Google informed us in late June, we've been working to
  integrate, test and deploy the security patches into all future
  products and software updates. We are also working with Google and our
  carrier partners to simplify the process of deploying critical
  security updates in the future.

The mentioned in the Motorola forum post,

We have started deploying software with StageFright patches across the
  globe, with more in the pipeline. Here is a list of devices with new
  software in either full or staged rollout. (Note: this list may be
  incomplete -- I'll update as new information becomes available.)

And the updates are released to the public to the following devices,

Moto G 1st Gen – EMEA/India Retail
Moto G LTE 1st Gen – Brazil Retail
Moto G 1st Gen – Brazil Retail
Moto X 1st Gen – Brazil Retail/Telcel Mexico
Moto X 2nd Gen – Brazil Retail
Moto E 4G 2nd Gen – Asia Retail
Moto G 2nd Gen – US Retail
Moto G 2nd Gen – Brazil Retail
Moto G 3rd Gen – Retail Brazil
Moto G 2nd Gen – India
Moto E 1st Gen – Brazil/India/US Retail

After appying this update you can feel secured from the Stagefright issue. But you never know there will be a new security issues everyday. So please keep your device software up-to-date.

I have a Xiaomi Mi Max, which uses MIUI 8, which is based on Android 6 dot something. It totally fails the stagefright detection test. Chinese manufacturers pay next to zero attention things like this. Aging the firmware (and worn out irreplaceable batteries) is their primary means of giving their products an intentionally shortened lifespan.
So what I do is make darn well sure that none of the messaging apps I use, ever have the setting to automatically download MMS media content. I also make sure I never browse any questionable website. Firefox supposedly has a safety guard that prevents using the libstagefright that avoids the problem, but I don't know if the Chrome browser, which I prefer, is safe (supposedly) as well.

Recover deleted SIM contacts
I have an Android phone. I accidentally deleted some of my SIM contacts which were not synchronized with my gmail account (actually, I hadn't synchronized my SIM or Phone contacts ever). Is it possible to recover those deleted SIM or phone contacts using software or any other method?
Please someone help.
Thank you.

There are couple of Contact Recovery App on Google Play Store. You can find out them here. Try them as suits you.

Unfortunately, you cannot.
You need direct access to sim memory for that to work. Any app that exchanges data (standard read and write of contacts, sms, few other id's) with sim card will pass the request to the micro controller on the sim card. And I don't think it is possible for apps to have data recovery level operations on the sim card's memory.

Better battery life by factory reset?
This is a bit odd. I thought I fairly well grokked how things worked, but this seems weird to me.
I have an original Moto X. I've had it for almost two years now. It started off with Android 4.2 (Jelly Bean) and, slowly but surely (because Verizon) got updated through to Android 5.1 (Lollipop). It has never been rooted.
I figured it's been getting a bit long in the tooth, and the battery life has reflected that. I could leave the house at 100% charge in the morning and, a two-hour train ride later, without ever touching the phone, would be down to about 60% battery. If I didn't charge at work, it would be dead by 2:00, with minimal usage. If I work at home, with reliable wifi all day, I can usually get to about 4:00 before having to charge. But, I figured, this is just what happens to a well-used phone toward the end of its life.
I finally got the Lollipop upgrade and had been using it for a couple of weeks. Things were okay, but not quite right. So I decided I had nothing to lose by doing a factory reset.
So, I did. I restored all the same apps back to the phone, with the exception of a couple that I finally realized I never use and some Verizon bloatware that I disabled.
But now, my battery life has improved tremendously. At home, with a fair amount of use, I never put it on the charger in the middle of the day and went to bed with 40% on the battery. I use an app that graphs my battery usage, and the slope is significantly shallower when I'm not using the phone than it used to be. I'm not using it any differently, but battery life is way up.
What could have happened? I used to check fairly frequently what was using my battery and there was never anything "weird" there. There also weren't any unaccounted for amounts. I am seeing the apparently irksome "Cell Standby" draining some, but even so the whole thing is lasting much longer than it used to.
I don't want to look a gift horse in the mouth, but I'm kind of wondering what I did by doing a factory reset.

I have similar observations, although I didn't use an app to track battery (good idea!). I often recommend people to factory reset once a year or so. Not just the battery life but also internal storage improves significantly.

You cleared Android's batterystats file by doing a factory reset, specifically the file /data/system/batterystats.bin was deleted and regenerated. This file holds a calibration for your battery. Before you did a factory reset, your batterystats was probably miscalibrated. It's a common practice, for rooted devices, to delete this file every now and then with a fully charged battery. This correctly recalibrates batterystats.

In an another universe, we have this: Google Engineer Debunks Myth: Wiping Battery Stats Does Not Improve Battery Life.

Change Chinese Samsung Note 5 Duo to English
I bought a brand new Samsung Note 5 Duo from Taiwan. Of course it is all in Chinese, but I was hoping to be able to change the language to English. The problem is that I wasn't able yet to get to the home screen with the icons to choose Settings. The startup screen seems to take me to wireless setup (I don't have any SIM cards installed yet but have an active wireless connection, which it immediately recognizes, but I want to work offline for now and disconnected). How can I get to the setup icon if all instructions and lists are in Chinese?
And I am wondering now whether a Chinese version will really be able to make everything in English, including the build-in applications. I may have to return it afterall. But it is such a beautiful phone. Does anybody know the impact of just changing the language to English? Will I really be able to use it properly?

A Chinese speaking person helped me and the answer was real simple:
The first screen that appears when you turn on your phone (Welcome Page) has a Chinese word highlighted and a forward arrow. Scroll the word highlighted down to the desired language :-) and click arrow. Everything turned into English immediately and you can continue configuring from there.

Gallaxy S3 recharging prob-Master reset? will I loose contacts?
I've had a Gallaxy S3 for a little over one year without problems. All of the sudden it won't charge up. Barely to anything after being turned off and plugged in for hours! I've switched chargers, even tried usb to PC, switched batteries with my husband, same problem. It's my phone, not the battery. I've done a cach partition wipe. No change. NOW...to my question. I am looking at doing a master reset. Will I loose my contacts and pictures?? Thank you for helping me. Can't afford a new phone at this time.

Yes, a master reset will wipe your downloaded apps and personal data.
You could backup your photo's on your PC. Another option would be Google Drive or any other cloud service.
Your contacts you can open contacts under settings. There should be import/export option. Then you can export them to your sim card or what every option is available. Also another option that maybe available is to save them to your Google or Samsung account.

Ok, thank you soooo much!! How do I back up my contacts, please?

Can I remove my SIM card before a master reset to keep my contacts??

I just watched this video and it instructs me to back up to SD card. Is the SD card the same as a SIM card and should it be removed prior to master reset?

https://www.youtube.com/watch?v=spAY40G49Jw

No an SD card is different than a sim card. You can move it if you wish. the sim card should not be messed with by the master reset just the device.

Unusually high data usage by Google Play Store
I've just noticed that my data usage for Google Play Store this month is >350MB. I've got it set to update over WiFi only and background data is restricted, so I don't know where this has come from. I haven't been downloading any apps either. Does anyone know what could have caused this and more importantly how do I stop it? It's a Sony Xperia Z3 running 5.0.2. Thanks!

I recently had problems with my phone eating up an extra 4GB of my data plan in one month. Not fun.
First try, Settings -> Apps -> All, and reset cache for each Google Play Services, Google Play Store, and Google Services Framework. Restart the phone, and watch.
If that doesn't do the trick, try resetting the cache AND data for each of the three. Again, restart.

can i get back up of photos. I've lost my android phone
i've lost my phone 2 days back in which my Google account was registered however i'm not able to find those pictures & videos now in my google account. I'm not sure if i had clicked on back up photos link or not. Is there any way i can get those photos. Plz help as i've so many memories captured in that phone.

Assuming you used Google to backup your photos, any backed up content would appear on Google Photos.
In addition, try using Android Device Manager to locate your phone, if possible. Or at least lock it.

New "On cbvl" notification on lock screen
I just noticed about an hour ago that on my lock screen, on the bottom left just above my phone icon, there is a new suspicious looking "on cbvl" notification.
There are 3 little notifications in the cluster. The first is the wifi icon with "sprint", which is usually there. The second is "Charging" which is normally there when I'm charging. The third is this new mystery line that has the silhouette-of-a-head icon (used for contacts) that says "On cbvl".
Does anyone know what this is? It is making me very nervous because I cant find anything on Google about it.

Figured it out.
My pocket was busy. It went to:
Apps> Settings> Lock Screen> Owner Info
And checked the checkbox, and then closed everything out.
Nothing nefarious. My owner name is just apparently "cbvl", and my lock screen was telling me that.

"com.android.phone has stopped" after reboot, cured by changing Preferred Network -- how to make permanent
Phone info:

"Google Play Edition" Galaxy S4 - GT-I9505ZWG
Android 5.1, build number LMY470.S008.150802
AT&T, Philadelphia

After rebooting the phone, I get the "com.android.phone has stopped" popup, and am unable to make calls or connect to the network.
I've been through the following steps to try to cure:

Clear cache for all apps
Clear data for "Phone" app (2 of them), as well as "CSC" and "com.phone.sec"

On a hunch, because there were issues last year with Google phones and AT&T support for LTE, I went into the "Preferred Network" settings and attempted to switch to 3G.
The first time doing this after reboot, touching the setting caused the settings app to exit. However, the signal strength meter then showed a signal, and I was able to make a call and connect to the Internet.
I then went back to this settings page, and was able to successfully change back and forth between 3G and LTE.
However, after rebooting, I was back in "com.android.phone has stopped" land.
It appears to be a settings issue, but which setting? And how to change? Is there a particular app that I should clear data for?
I don't want to do a factory reset, especially since I have a work-around.
If necessary, I can get logcat output. However I'd want a pointer to the specific output required, rather than dumping the whole mess into the question.

multiple android devices using same email address question/
I work for a company which uses many android devices (tablets). Same level of users share same email address. When an email is sent to a group,they all get the emails but only one of them is receiving the email alert from the tablet. Is there any way to configure the tablets to have all of them alert when new email is received? We use Samsung Galaxy tablets with Android. Thank You.

As I wrote in a comment on this answer: As soon as someone reads the mail (or dismisses the notification), no more notifications will be done – as the recipient has "acknowledged" the information. I doubt there's a way around that other than using separate mail addresses.

I think other tablets didnt turn on the notifications of New arriving emails.
Go to email -> settings -> 1.tick the EMAIL NOTIFICATIONS.
And also check you have tick the SYNC EMAIL.

That should work – until someone receiving an alert dismisses it (or reads the mail). From that point on, no more alerts will be "delivered".

ADB can't find Nexus 7 after bootloading
I am trying to update my (unrooted and unlocked) Nexus 7 2013 wi-fi to Marshmallow via OTA. My Nexus is in USB debug mode and I have installed adb on my system and download the update package file.
When I connect my Nexus to Windows 10, the system recognizes the device as Android ADB Composite and everything seems to be working as it should. I open a command prompt and type:
adb devices
and the device along with its id is correctly shown. At this point I reboot to bootloader, so I type
adb reboot bootloader
the Nexus reboots, enters in the bootloader and the following happens:

adb can't find the device anymore
the device manager puts the Nexus among the Other devices and so it appears no driver has been installed for it.

As suggested on numerous tutorials, I right-click on the device and choose to manually install an appropriate driver. And I expect to find Android ADB Composite in the list and instead the only possible choice is Samsung Android ADB Interface — which does not work, because, naturally, Nexus 7 is not a Samsung device.

I have tried to solve this issue by installing the google usb drivers using the 15 seconds install and it didn't help at all.
What can I do to overcome this issue?

There is no problem here. Why would adb devices detect anything when device is booted into fastboot mode? You need fastboot binary in PC which uses different protocol to interface with your device. During fastboot mode, your typical Android OS is not running (neither the bootloader has any provision for adb daemon) so using adb is futile.

@Firelord I am sorry, I am a bit confused: in order to actually transfer the ota file I will have to use adb sideload, so how can adb initiate sideloading if it can't find my device?

Please link the tutorial you're following. Note that sideloading an update is done when booted into Recovery mode which is not Fastboot mode. See [tag:recovery-mode]. Instead of the command adb reboot bootloader do adb reboot recovery when booted into Android.

@Firelord this is the tutorial: http://www.androidcentral.com/how-manually-upgrade-your-nexus#slide5

It is mentioned there "Now use the volume down button twice until you have scrolled to Recovery mode" -- which is what I wrote.  Simply boot into Recovery mode and then begin sideloading. That's all you've to do.

@Firelord I have initiated sideloading and I get error: device '(null)' not found. Maybe, I guess, that's because adb can't find the Nexus in the first place.

That is a different question and discussing it here would be off-topic wrt to this question. Please post a new question for your new issue.

Galaxy S5 after System Update is asking for SIM Network Unlock PIN
I recently purchased a Galaxy S5 on http://amazon.co.uk. This was a well deserved upgrade from a galaxy S2.
When I got the phone I powered it on with my Vodafone Spain SIM card and it worked perfectly. The day after I realized that there was a system update and I ran it. As soon as the update ended the phone asked for "SIM Network Unlock PIN"
Is there any way to revert this update? is reverting the best option?
Can I unlock the phone without buying an unlock code?
I found this site http://unlockcode4u.com recommended by a friend and they seem capable of unlocking the phone, but I just expended £250 for the phone and the code is really out of my budget.
Please help.

First contact your service provider Vodafone Spain because OS upgrade does not cause such issues.

Thanks for your reply. I purchased the phone as new and unlocked in http://amazon.co.uk. Does my provider have something to do with this update?

My suggestion would be to talk to your network provider and ask them why are you seeing the above mentioned error message only after updating the firmware. Ideally it should not happen as you have bought an unlocked phone.

Thanks for your answered. I did contact Vodafone here in Spain but they actually did not know how that happened. I was on the phone with them for over an hour and no solution was given. Eventually after all my frustration on the phone and researching online for a solution, I finally went back to this guys http://unlockcode4u.com and bought the unlocking code. My phone went back to work after 2 hour with their unlocking code. I should have done this from the very beginning and saved me all the hassle.

Samsung S4 Google Sync Settings Problems
When I am in settings, Accounts, Google, myemail@gmail.com, I see "Sync turned off. I select it and get a list of things I can sync. I can hit each and sync it, but there are no check boxes to auto sync certain features, I have limited data and don't want to sync all continuously, not that I can see how to anyway. A few minutes ago, at the bottom I could choose 'Sync All', now that option is gone, this whole screen makes no sense to me, basically, I always want to sync contacts, gmail and Chrome settings, nothing else, anyone know how? Always in awe of how bad menu designs/UIs (don't) work.
Thanks much!

I am using S4 Kitkat though, however I was in the same situation where I needed to enable Sync for selective Providers like Google mail, Calendar, Contacts (not Google Games, Google Books etc).
I ended up using the Synker App (Paid) to achieve those. However, not sure if it works equally well in Lollipop!

How to restore contacts in android 6
Today I flash android 6 on my nexus 5. It is really not ready to use the system. I have many problems. For example, all my SMS have been deleted. It is OK. But I lost my contacts too. How to restore them?
Of course, I logged into my account. Of course, I have WIFI. Usually, contacts restore from Cloud backup, but not now.

Contact means your Phone contact or gmail contact ?? Well if you are asking for gmail contact then go to your gmail account and check out your contacts are visible or not ? Go to this link - - http://www.google.com/contacts , if the contacts are there then you can easily access that on your phone via google sync.
Try this software - ->  Android Data Recovery
1) Download the software from the below link, install the software in your PC
2) Connect your Mobile with PC .
3) Turn on USB Debugging by going to - -> Settings - -> Application --> Development- -> USB Debugging.
4) When your Phone get connect with PC, you have to press Start button to start the scan, it will take 20-30 min to scan.
5) When scan get complete, you will see your contacts and other options like SMS on the  left pane. Select the relevant option that you want to restore and Press - -> Restore.
6) Disconnect your phone and check out your contacts in the phone.
Taken Reference:
http://www.androidphonesoft.com/resources/recover-deleted-contacts-from-samsung-galaxy-s4.html

Same happened to me. It helped when i opened recent calls tab in dialer and loaded full recent history. It managed to get most of the lost numbers from there or anyways it helped. Worth of trying.

My LG is indicating low storage space
My LG is indicating low storage space. I cannot install new applications. I still have more than 7G free space. Please what can i do?

Here is the salvation: http://android.stackexchange.com/tags/insufficient-memory/info. Also, give us the output (screenshots) of Diskinfo and DiskUsage. You may have to delete an app or an app's data  to get some space for the said apps' installation.

Its a good tactic to reboot the phone clear up useless apps and move your pics or whatever to another place(may be sd card?).you should check the storage options in settings and that will tell you whats causing the error.

I think it is becasue of cache files go in settings>storages>cache data and clear them....and some of google apps like gmail and google now saves alot of data on your device be sure to clear that and go in storage and apps section and it ll show you the list of apps sorted on basis of their size(large to small)....clear their data...

you mentioned 7G free space,but in sd card or in internal memory?
all apps and app data may be stored in your internal storage.
Move your data to SD card and try installing new apps.
hope this will be helpful.

What will happen if I update android apps over internet on a rooted phone on Google play store
If I update android apps over Google play store on a rooted phone will my android apps get updated or is it illegal to update or will my phone get damaged.

I'm curious. Why do you think it would be illegal to update the apps on a rooted phone? (Note that legal questions, such as "Will X void my warranty?" are off-topic here.) What is the basis behind the thought that the phone will get damaged? I failed to see an issue here. There is simply no context given to us.

I'm voting to close this question because legal questions are off-topic here.  For the other part of your question, see http://android.stackexchange.com/q/164/1465

A rooted device just means that the root user has been exposed. In other words, apps and other things have the ability to access data that could be seen as sensitive or dangerous. As long as you do not give root access to untrustworthy apps, you are fine. You will not damage your device or do anything illegal.

Can too many text messages and phone calls cancel out your alarm?
I was blamed for canceling a friend's alarm clock from half a country away and recently I wondered if it was even possible.

I just tried that with my phone. I created an alarm for 1 min and I gave a call to my phone. During call it vibrated for alarm, and when I cancelled my call it was still vibrating, notifying me of my alarm.

Port forwarding in android
I have a rooted android device in which I have installed SSH server. i need to access my device outside my LANi.e. over the internet.inorder to access it over the internet i need to enable port forwarding . so , is there any way of forwarding ports in android?

What's the network scenario here? If your Android device is under a local network, be it wired/wireless, and the device has to be accessed from a system outside this network then you would need to forward ports at the router/switch -- off-topic here. If the device is simply connected to Internet (using mobile data) and has a public IP address, then you should be able to access the server without any port-forwarding.

I meant i can access it in my LAN . But i cant access it via my public IP

What does "Service google play" application actually do?
First of all "Service google play" (in Russian "Сервисы google play") is not play market appication which is used to download and install applications from play market. So what is the problem with it? I spot that "Service google play" (in Russian "Сервисы google play") took about 100Mb (for strange searching data) and cleanuping application data does not help - after several minutes they are magically restored. I wonder - can  it be safely removed (or disabled) from phone? Or it is a system important process?
Note
It probably good to provided a link to google play, but I can not find that service (may be english name is different) in play market.

In response to your note, one does not simply find Google play services/Service Google play by searching the play store.

Added to the exaggerated "Apps may not work if you uninstall Google Play services" from the app's description (see e.g. the answer of SuperThomasLab):
Many apps found on Google Play depend on this, but by far not all. Apps e.g. from F-Droid mostly can live without it. One can think of Google Play Services as kind of "shared library" for "many things Google".
When using a custom ROM without GApps, it can e.g. be substituted by migroG GmsCore – I've just done that on one of my devices :) microG GmsCore, as the name-part "Core" suggests, offers the essential services many apps rely on – but without all the overhead Google's app ships with. So it should be much less aggressive towards the device's resources. Please see the linked XDA thread for details and up-to-date information – which also gives you ideas on what Google Play Services does:

Ads/Analytics API: will not be covered by microG
Auth API: authentication with Google's services. Covered by microG
Cast API: in the works (microG is still young :)
Drive API: Google Drive stuff (not yet in microG)
Fitness API: not (yet) in microG
Games API: not (yet) in microG
Cloud Messaging API: fully functional in microG
Location Provider API: fully functional in microG
Geofencing API: not yet supported in microG
Maps API: partly implemented in microG (work in progress)
Plus API: minimal support with microG
Wearable API: work on this has just started in microG

From this list you can get an idea what Google Play Services include. And from the "state" mentioned toward them for microG, you should see why it's more lightweight. I for one hope that, if implemented at all, Fitness + Games at least go to a separate app which one only need to install when needed; I don't need that, so for me it would be bloatware :)

Google Play Services is hidden in Google Play. You can find it here.
Google Play Services is an app that brings the newest features to older phones, like authentication to Google Services. When you uninstall/disable Google Play Services then most of the apps on your phone won't work properly anymore.
Description copied from Google Play:

Google Play services is used to update Google apps and apps from Google Play.
  This component provides core functionality like authentication to your Google services, synchronized contacts, access to all the latest user privacy settings, and higher quality, lower-powered location based services.
  Google Play services also enhances your app experience. It speeds up offline searches, provides more immersive maps, and improves gaming experiences.
Apps may not work if you uninstall Google Play services.

Using TTY on Android without requiring additional hardware
Is there any solution to use full TTY (text to text communication over regular telephone communication) from Android?
Despite the fact that Android's default Phone app has an option for full TTY support, it doesn't seem to allow communication with a TTY number. What else is needed to communicate using TTY?

I'm not sure about the tags here. The Phone app does not seem to have a tag, nor does TTY.

Since there's no TTY tag here, could you expand this question by at least explaining what's TTY in a simple way? Is it similar to teletypewriter? Also, just in case, could you also explain what are you trying to do? Perhaps we can suggest alternative solutions. (e.g. realtime messaging app)

@AndrewT. Yes, the link that you mentioned. Teletypewriters provided an early method of sending textual data over phone lines. Very rudimentary. Clearly inferior to texting. I need to communicate with a government agency that has no email or other form of communication that I'm able to use as a part-deaf person. Their TTY support seems the only option. However, it's a  very dated technology, so it's very hard to find up-to-date information on using it aside from the fact that Android's Phone app has a mode for it. I'm looking for a software solution to using TTY for communication.

It seems the built in TTY modes are only usable if you plug an external TTY terminal into the audio connector, according to this ehow article: http://www.ehow.com/facts_5230442_tty-mode-cell-phones_.html I wasn't able to find any software only solutions for Android either, I'm afraid this is because it's a feature that is used so rarely that nobody has created a software only solution for it (yet).

How do I join a hangout from my Calendar?
I recently purchased an LG Tribute phone (Virgin Mobile carrier).  If I open up my Calendar, I can see a scheduled meeting in their that uses Google Hangouts.  Under "Location" there is a link that reads "Use Hangouts".  Unfortunately when I click on that link, I am taken into Google Maps.

Silence volume control rocker click
I have an FonePad X, android 4.4.2.  When I go to bed at night I turn down all my volumes.  But the volume control rocker emits a beep when I use it to turn down the volumes.  I don't need a notification that I'm turning down the volume, and I'm trying to be quiet so as to not awaken my sleeping partner.  I find this annoying.
Is this volume control notification sound silence-able?

Is the device rooted? Gravitybox can do this easily. No root needed: Tasker combined with AutoInput can also do the job. There is more. You can create  a shortcut on home screen that will decrease all the volume so you don't even have to touch the volume rockers, let alone disturb anyone in vicinity.

No, I'm not rooted, and I can't root as I use my phone for work related stuff (calendar things) and they prohibit rooting.  My latest trick is to install a white noise app and start that app before I enter the bedroom.  And I now go to bed first, so it becomes a moot issue.

Browse file system from PC in marshmallow
I have a LG Nexus 5 with android marshmallow OS. I used to be able to connect my phone to a PC running Windows 10 with USB cable and browse the files from the PC's file explorer. Ever since I upgraded the OS to marshmallow whenever I connect the phone to PC with USB cable, the PC detects the connected phone but when I open the phone from file explorer there is nothing shown.
After a lot of exploration I found a setting in the notification area called 'USB for charging. Touch for more options'. From there I can choose charging only, MTP, PTP, or MIDI. After selecting MTP I can browse the phone content from PC. This setting used to be in Settings - Storage - USB computer connection.
The problem is the next time the phone is connected to the PC, the setting revert back to 'charging only'.
Can I set the default to MTP like it used to be in lollipop?

If phone is rooted, run the command setprop persist.sys.usb.config mtp in the terminal and reboot

The reason for your problem  is mentioned in the changelog of Android M: "Device connections through the USB port are now set to charge-only mode by default. To access the device and its content over a USB connection, users must explicitly grant permission for such interactions.".

No Google apps and no install zip option in recovery mode
I have a galaxy s3 and I put CyanogenMod on it but there are no google apps and when I boot into recovery mode there is no install zip option to install the gapp ROM how do I get the Google apps on there

Which recovery are you using?

If you're on Cyanogen recovery, Go to Apply update -> Choose from sdcard0 -> gapps.zip

Seems that your recovery got broken, Now you'll have to flash another one the same way you did the first one, via Odin, and i recommend you this version,

CWM_Touch_6.0.4.4_with_Odin

After you flash the recovery, Boot into it, Then select the "GAPPS" version that is compatible with the ROM version you've installed, If you don't have it, Just choose the compatible one from this thread

GAPPS_ALL_VER

Once you flash GAPPS, you're done.

Change when phone beeps for notifications
My phone makes a lot of noise when it's not in use. I think this is because apps running in the background have experienced an event, like Clash of the Clans. How can I change this? I'd really like to find out what apps just made my phone beep. I'm running Cyanogenmod 12.1 with android 5.1.1 (though soon to upgrade to android 6).

i didnt get your question...do you want to turn off your notification for a particlar app or something like that..???

@Anko basically yes, i want to turn off notifications for a particular app, I just don't know which app keeps making the phone beep

Maybe not the answer you want, but can you clear all notifications and check your phone every time it beeps? There should be a notification relevant to the beep. If you think that the app's notification is annoying, you can open the app and check the in-app settings for notification (generally, there's a notification setting in the app itself). Otherwise, follow Anko's answer if you don't care about their notifications.

@AndrewT. good point, I'll try it

Lets take an example that its your clash of clans app(as u mentioned it in the question)...go in settings -> app -> select that app -> there will be a checkbox which says 'show notification'. Uncheck it

Ok thanks. So unchecking this will prevent audio notifications as well as the notification being added to the lock screen?

Yup.... If you appreciate you can give a +1 to my answer

adb sideload Throws error: closed on Nexus 6
I am trying to sideload the Android Marshallow OTA on my Nexus 6 using adb sideload "<android marshmallow OTA>.zip", but the console keeps printing out error: closed with no success. I verified that I have enabled USB debugging, but this is still a problem. I have tried running adb usb as well as adb kill-server and adb start-server as well as rebooting the phone to resolve this, but so far, no luck. I have also tried unlock the bootloader, although that did not seem to help.
The phone's Android Build Number is LMY48T (Android Lollipop 5.1.1)
Does anyone have any idea how I can fix this? I am running Windows 10 Pro x64 on the machine on which I am trying to do this.

Does adb devices list your device? Proper adb drivers installed?

@Manubhargav Yes, adb devices does list the device, and I do have the proper adb drivers installed.

Before you executed adb sideload command, did you explicitly enable sideload option in your recovery? Which recovery are you using?

@Firelord I am using stock recovery.

@Firelord I feel like an idiot now. I haven't been able to do this because for some reason, my phone would lose its connection to my computer after executing adb devices. Pulling the connection and plugging it back in seems to resolve the problem. To answer the first part of your question, yes, I had selected the sideload option when trying to do this.

Galaxy S5's screen only turns on after multiple presses, and the screen has these weird lines show up when turning off
and thanks for reading this. So I've had an S5 for just over a year now. As it has an AMOLED screen, when you turn the brightness all the way down, the screen will flicker a yellow-green. This happened whenever the screen would dim on standby, and it seemed that it was normal. However, now, when I power it off, the screen does the green flicker when it's fading out. This did not happen before.
On top of this, sometimes the screen simply will not turn on. The phone is on, the lights are on, but I'll press the power button, and nothing will happen. I'll keep pressing it, and eventually it will turn on, but this could be part of an underlying issue. If anyone has any ideas, please do tell me.
Also, smaller issue: woke up one morning, and a notification came up at 3 AM saying that I was running out of storage space. Is my phone trying to kill itself?

The first part of this screams either a broken screen or much more likely, a broken screen driver (Software being corrupted). Backup your data and factory reset the device. Do not recover using the backup and just move your contacts back and pictures. You can always reinstall apps. If that doesn't fix it, you will likely need to replace the device or flash the stock software again.

Ok, I'll get on it this weekend. Are there any backup applications you recommend in particular, or should I just copy some contact/picture file over?

@GMY0da as long as you download all of your pictures and sync your contacts through Google, you shouldn't need a backup. If you want to check to make sure your contacts sync, open your Google account and check your contacts through a web browser.

Just warm up the screen.  It will come on.  Mine has been doing that for weeks now.  If it is kept in a warm location it will work perfectly. ( above room temperature)

Tasker: Turn wifi on/off scheduled
Looking for a way to turn off my wifi everyday at 9:30 pm.
And turning it back on at 7:00am the next day automatically everyday.
Tried a few profiles, none really worked.
Thanks for your help.

What kind of profiles did you try, I wonder?

I don't know what profiles you've tried, but that's one of Tasker's easiest jobs:
Condition: Time (set start and end time)
Task: Net › WiFi (set "off")
That's it. At "start time" WiFi will be switched off, and and "end time" the setting is reverted to what it was before the condition matched. If you want to be sure that's always "WiFi on", use an exit-task similar to the described task, just with Net › WiFi set to "on".

Push Android Exchange Calendar to Google Web Calendar
Let me start off by saying this question is essentially an updated version of Access synced Exchange calendar from desktop browser but not a duplication
I have a work phone with Exchange access over VPN, let's called it me@work.  This syncs to an Android phone running the VPN tool but uses my personal Google account me@home.  I don't want or need to carry the work phone around during non-business hours, but it's great to know "oh I have a meeting tomorrow morning" or when making personal plans to know what my schedule is like without having to say "Let me check my work phone later to make sure I'm available"
me@work uses the Google native calendar app on Android.  I don't currently sync my personal calendar to my work phone, but me@home is the main Google Account on that phone.  Is there anyway to publish/sync those appointments to https://calendar.google.com/calendar with an app on Android?  This would enable the events to show up on the webpage, and since they're syncing with my personal Google account they would likewise show up in my personal phone.
As bonus points, is there a way to have this be a one-way or isolated sync, so my work calendar doesn't show personal events?
My company's Exchange server is only available over VPN, so I can't just sync directly to my personal phone.

It is a little bit late but maybe there is a solution now: Someone else had the same problem and asked me for a solution. I have created an Android app for this purpose now. It can copy/sync a calendar (e.g. your Exchange calendar) into another calendar (e.g. a new Google calendar that you create in your me@home Google account). This way you can see your work events in your me@home Google account but your personal events won't appear in your me@work work account.
It is a one way sync from your Exchange account into your Google account:
Exchange (me@work) -> Android calendar -> SyncCal -> Android calendar -> Google (me@google)
You can find the app here: https://play.google.com/store/apps/details?id=com.calengoo.synccal
It can be used for free but it also contains an In-App purchase for an automatic sync.

I used an app call e.sync from the Google play store and it works great. All of my work calendar events syncs to my Google calendar which shows up on my personal phone

Can you link this app?

You should mention the full name of the app: Exchange Calendar Sync

Audio applications (spotify etc) continue playing when bluetooth calls come in
When I'm in my car and listening to the ESPN Radio app, the Spotify app, or the Soundcloud app, and I receive a call either on my bluetooth or the d/c phone itself, the audio application keeps playing the podcast or music over top the call. This only happens some of the time, sometimes it pauses as it should.
Also, this may be related. If I get in the car after using spotify on headphones, it will start playing on the bluetooth even if I had paused and closed the app long before. I'm not sure if it's related, but it's more strange bluetooth issues.
My phone is a completely up to date Samsung Galaxy S5 with no alterations like being jailbroken or anything. Just a base model S5. My carrier is ATT.

How to enable Vibrate on call connect?
I am using Android lollipop 5.1.1 on Google Nexus 5. I used to have a feature on Nokia feature phone, which would vibrate the phone when the person at other end picks up the call. I want this kind of feature on Nexus 5. I have no root. How do I do it?

Go to Settings → Sounds,  scroll to bottom and tap Also Vibrate For Calls.

I noticed that it only vibrates when I receive call, not when someone picks up my call.

Sorry, but I'm not sure this is possible without root. You may be able to use a third party app but there is no "built-in" feature like this

How do I get MyBackup Pro to back up Chrome bookmarks and not the stock browser?
On my S6 I thought my Chrome bookmarks were being backup to the cloud using MyBackup Pro only to find it just backs up stock browser bookmarks.  Other backup apps in the Play store back up so many things like SMS etc. but how do I backup just the Chrome bookmarks locally or in the cloud?  Google's own sucks.

Just one single query: Does this MyBackup Pro needs root access or not? If not, then it can't backup Chrome bookmarks since they are located inside Chrome's data directory and an another app cannot access them unless it has quite high privileges, or an alternative and explicit way is available (I've never seen one). Even ADB would fail since Chrome for Android  disallows its backup. You'll have to rely on what I said here.

But the device is rooted, so why use MyBackup Pro when the champion of backups is here?

@Firelord  Seems to have bad reviews and bad interface. I remember looking into Titanium. Can it back up.Chrome  bookmarks?

It can backup the whole Chrome data, but not the bookmarks explicitly.

I tried this pro app, and I found that it doesn't give the option to backup any system app (which includes Chrome),  so you won't be able to backup your bookmarks using it. It's too bad because the app has root access. On a side note, don't go for the review on TitaniumBackup since it seems to be first choice amongst the users here. Plus, ask a question about it if you don't understand or has problem doing something in it (though many have been asked already here). I'm certain about my info about that Pro app. So, should I write my answer or you need something more?

Wait, I have something different to add now. I deleted my stock browser long time ago, so I've only Chrome and Firefox. When I backed up my bookmarks using that MyBackup Pro app, I found that Chrome bookmarks were actually backed up, and then restored well. So, if you don't use stock Browser, then simply disable it and then try this app.

So, did the comment work for you?

I left my phone charging over a 24 hour period and now it won't turn on. I tried cleaning it out, taking out the battery, and putting it on the charger. I don't have a spare battery to try. Is there a way to fix it?

I think your battery is dead, buy a new one.

I think most of not starting up and flashing are related to the faulty power button. Here's the link you can follow on how to troubleshoot the power button if it's working properly or not using a voltmeter.

The battery is the best place to start. Overtime they tend to wear down. (I had the same issue on my Galaxy S 3 and it took a new battery)
Otherwise, it could be an issue with the motherboard or something more fragile in the phone. Could also be a power button failure.

You could see if you get anything from removing the battery and connecting it via USB cable to a computer.  You'd be powering it from the USB cable, possibly enough to turn it on.

Where is the recovery installed on Android phones?
As far as I know, every Android phone has a stock recovery. Where is this recovery usually stored? On a separate partition in internal storage(usually an eMMC memory chip)?

It's exactly as you say: A special partition only storing the recovery is used. It's about 5-10 mb large and doesn't interfere with the boot procedure.

A good starting point on that is our partition tag-wiki – which also mentions a good article on this topic: Android Partitions Explained: boot, system, recovery, data, cache & misc. Also see on our site: Android Folder Hierarchy
