How to stream music from one android device to another?
I have an android tablet in my car which is connected to my car's Audio System. My Phone has my most recent music collection on it. How can I directly stream music from my phone to my tablet, without having to copy the files or the devices being on the same wifi network? Can this be done with bluetooth? Both devices are running Jelly Bean.

This app could do the trick:
Bluetooth Music Player Free
You need to install it on both Android devices and pair them. Then put the tablet in ListenMUSIC over Blueetooth mode and the the phone in shareMUSIC over Bluetooth mode.

From Illuminati's store... er... I said from Ilumnis one?

@kokbira Yes, from Ilumnis as a developer/publisher on the Google Play store. The free version is enough.

extremely buggy program :(

This does not answer the original question. Bluetooth Music Player Free apparently only receives song names, and tries to locate and play the file on the "receiving" devices. So it requires to copy files beforehand, which the original question ruled out.

Apart from "Bluetooth music player" (mentioned in above answer), you may also try SoundSeeder speaker or SoundSeeder Music player. As i remember, at first you should pair the devices. From the description of SoundSeeder Music player:

Soundseeder turns all your devices into into wireless speakers. Play your music louder and share it with your friends.
  All connected devices (Android, Windows, Linux, Raspberry Pi, ...) play the music in sync as one large sound system.

SoundSeeder speaker is

a speaker-only version of the SoundSeeder Music Player and was designed for devices running Android 2.2 - 4.0 only.

It's really hard to do that. But I did a lot of research and got a way. Has several delay, connection and root problems, but apparently works. For this you will need to have the "AirAudio" application installed on the server and the "AllConnect" receiver. Then you open AirAudio on the home screen and then open AllConnect, press on your device, then on sources and choose the server, then choose the streaming mp3. The problem is that the delay is very large and another defect is that to transmit only the sound of the system of the android server you should have root on the phone ... I also tried the receiver of the streaming being the VLC, was less delayed but still So it's uncomfortable.

establishing USB connection takes > 3 minutes and times out, charging works
Some time ago I've been able to connect my "Smart"phone to my Ubuntu 14.04 PC as mass storage device with an micro USB cable hitting the ~"Activate USB storage" (translated) button in the notifiaction pull-down panel which appeared after the cable has been plugged in. Now, establishing an USB connection is tried for > 3 minutes and then times out; the animated waiting icon (spinning circle in which the button to activate the USB storage is transformed to) changes back to the button to activate the storage. Some infos:

occurs 100 % of the tries
restart doesn't help
cable seems fine because charging works
Android 4.0.4 on SansuiCosmic SP 1001 trying to connect to Ubuntu 14.04 with Linux 3.15.9 without problems with USB experienced so far.

I've never seen an "establish connection" button, could you get a screenshot of this? What mode are you trying to connect in? ADB/MTP/PTP/Mass device?

"cable seems fine because charging works": disagreed on the reasoning. USB plugs have at least 4 (some have 5) pins in use. 2 are for power, the other two for data. So if one of the data connections got broken, it would still charge fine. // Have you tried a different cable?

Can I Install Only The Google Account rather than the entire stack?
I am currently running an Aosp-based custom rom on Android 4.4.2 with zero bloatware, yeah, I detest bloatware. After going through struggles with the amount of resources Google's play services do to my phone and my phone's data usage.
I had to get rid of the entire gapps package for good by re-flashing the rom without flashing the gapps package. I've also had to do offline install of Android packages, and all apps requiring I've got an Active google account have had to suffer an unpremeditated uninstall.
Now, I have so far survived without a google account on this phone, I miss Chrome's Sync with my PC though, but I was just thinking if the gapps package could be extracted from the Android OS, is there an alternative/mod for those of us who only want explicitly a google account in Settings > Account without Play Store, Gmail....etc

Custom ROM... So your phone is rooted. Have you tried to just remove the apps with titanium Backup? That way you can log in and only have the account

Erm, I've never had any luck using titanium backup, the app just seems too complicated to use.

You should try it. You should be able remove the g apps that way.

But will I need a paid version of Titanium Backup to get this done?

Probably not. I've removed apps with the free version

You might wish to check with Are there any solutions other than flashing Gapps, to have Google accounts on CyanogenMod? – where I named an alternative:
On XDA, you can find the NOGAPPS project, which basically is an OpenSource replacement of most Google apps (including Playstore), often mapping to free alternatives (e.g. OpenStreetMap for maps). The "elements" come as separate packages to install, so you can pick the ones you want – and simply skip the others. Status is different for each of the services: some are actively developed, some are "not yet usable", some seem even to be "abandoned" (like the Playstore replacement BlankStore, which is discontinued since 2012 – but luckily seems to have a successor named Blank Store).
I've not (yet) used it, so I cannot tell which parts are essential or how well those replacements work. But head over and check out for yourself. Marvin seems to still actively be on it (last update of the "lead post" was just a few days ago).
As for "zero bloatware" and "Android without Google", you might also wish to check my answer here ;)

If you have a routed phone/android, log into the system as root and use the program manager "PM" to systematically remove each app/gapp you don't want.  If that breaks a feature you need, use pm to put it back and move on to other "bloatware" you want to remove.
To use the shell install the Android SDK package.
I would suggest that you backup a package before removing it:
Is it possible to backup apk from an installed application?
So, having your clean custom built rom, you should be able to use the same feature to individual install which particular gapp you want from your backup.
Installing an app is simple from the cli:
$ adb install -s example.apk

By the way, this is a good reference for the Android Debug Bridge (adb) commands.
Look at the install section:
install [options] <PATH>

-l: Install the package with forward lock.
-r: Reinstall an exisiting app, keeping its data.
-t: Allow test APKs to be installed.
-i <INSTALLER_PACKAGE_NAME>: Specify the installer package name.
-s: Install package on the shared mass storage (such as sdcard).
-f: Install package on the internal system memory.
-d: Allow version code downgrade.

Install king root
It will root yr phone vry fast n easily

You can try kingoo root it works with or without a pc i root or find a guide not on play store try 9 apps or apk pure

As a can see it has a Rockchip CPU, you try root it with VROOT http://www.mgyun.com/en/getvroot . Rockchip sells the majority of it chips to chinese OEMs that's why its very likely that VROOT will do the job. Please try it and reply back :)

Sir it worked! Thank you very much! Can you please also help me regarding the installation of  custom recovery menu?

I think Custom Recovery Menu depends on device so I don't think I can help you with that. But keep in mind that the Custom Recovery Menu that you will install must be made specifically for your device. So DONT try to use a Custom Recovery Menu from other devices.

is there a way to identify my tablet specifically? model, brand, etc?

Maybe in the settings of the tablet, at the About Device senction?

Model Number: MID
That's all

So if you succeeded, it would be fair to add the needed steps to the answer and accept it as solution.

Analyse performance / profile Android System? Why is the system slow?
My Android 4.2.1 tablet is slow, it wasn’t when purchased. As the reason is often the software, I was looking for a tool to analyse the performance of the whole system, but couldn’t find any.
What I tried:

CPU usage monitoring: Only current or accumulated CPU usage
An app that alerts when any app uses more CPU than a specified threshold: This only alerted quite seldomly, so there doesn’t seem to be an app that uses so much CPU itself

To find out the reason of the slowness, I would like to get an overall view of the system’s performance, showing how much time was spent with which activity. This may include CPU usage, but may also include I/O performance or how long processed waited for I/O etc. For example, Firefox offers a profiler.
Or is this not really possible because of Android’s design?
Are there other utilities that might help?
Another point is that Android doesn’t support TRIM until 4.3. Could the usage of nearly two years with many installations and some system resets have caused the flash memory to get so slow that the poor I/O performance now slows down the whole device?
To the manufacturer’s support, I wrote the following problem description:

Opening of apps takes longer, sometimes everything stands still for
  some seconds. After the last firmware/Android upgrade (a year ago) I
  even reinstalled the system. However, after some time, it got slow
  again.

Only after this vague and undetailed description, the reply said that the reason would most probably be a hardware defect and that I should send the device in to be repaired.
How should I continue my analysis? Is the support’s assessment reasonable?
Update
Recently, a new app was added to the PlayStore concerning exactly one of my desired analysis:

CPU Monitor (non-free, restricted demo)

For first-aid and getting started, please consult our performance tag-wiki, which has the required pointers. Then come back here and either answer your own question (if you were already able to solve the issue), or [edit] it to include what you've tried and where you're stuck. Thanks!

If the manufacturer thinks you should send it in for repair, you should probably do that.

Confirm if apps have successfully installed from Google Play (Without looking at the phone)
My girlfriend recently had her phone stolen and I'm trying to track it down by remotely installing apps on her phone via Google Play, but I can't tell if the apps are successfully installed.  For example, if I turn off my phone completely, and install an app on it from Google Play, it will still report "installed" even though my phone's turned off.

The answer to your specific question is, unlikely.  You can install an app that has an interface that you can communicate with.  Communicating with that interface can allow you to know.  But other than that, it's unlikely.  And you'd have to have confirmation on the android to accept the manifest of the app's requirement list.
You may not be fully lost, however,  Google does have a feature by default that you might be able to track your phone even if you didn't install an app.
These are some requirement which most people normally have:
- The android is connected with your Google account.
- Your android has access to the internet.
- The the Android Device Manager (ADM) to locate your android (turned off by default)
- Allowed ADM to lock your android and erase its data (turned off by default).

Try Google's Android Device Manager.

I won't answer the question itself, but the general question on how to find the stolen phone, and for sure the way you trying is not going to get you anywhere. In order to have a chance to find the stolen phone you should have already install any anti theft app like Google's Android Manager or Cerberus or any similar app. Of course these apps will work only if the thief has not already uninstalled them or reset the phone and installed a new ROM.

So is there a way to check, what are dead ends? Because the phone will ring for a while... but then shortly they turn it off after we try to call it.

I've been trying to install android lost and then text it "androidlost register" ...but that seems to not be working... even though it says it's "installed"

Go to google play on a computer and try to install an app. After pushing the Install/Installed button a popup will appear listing the permissions it requires and below that a drop down listing the devices you can install it on. Click on the drop down. If it is currently installed it will say "Your device already has this item installed" next to the device name. Otherwise it will say the last time the device was used.
I just tested this by installing an app and canceling it in the middle of the install, then re-installing it, then uninstalling it.

Is it possible to run fastboot in a recovery mode shell (without connecting to PC)?
I have a method for unlocking the bootLoader of my HP SlateBook x2 running Android v4.3 consisting of:

Booting into recovery.
Connecting to PC via USB cable.
Sending the command fastboot -i 0x03F0 oem unlock to the Android device.

But this device has an incredible problem: it sells without USB cable (LOL), so I have no USB cable at all.
But I have installed TWRP recovery, that includes a root command-line shell. So, as long as I can not connect via ADB bridge by using USB cable nor ADB via Wireless (the recovery mode does not detect the Wi-Fi card), I was wondering if it would be possible to use this shell to send the fastboot command from recovery mode in the stand-alone device (without any connection to PC, as long as it is not possible).
Any ideas, please?

I've edited your question to not mention ADB, since fastboot is not an ADB command and doesn't use ADB.

Fastboot commands are for the bootloader, not recovery, so even if you send the commands from recovery, it would do no good since you would be in recovery, not the bootloader.
According to all the information I could find about this "tablet," including information from HP, indicates that there is no way to access fastboot since there is no USB port and HP doesn't make a dock-port to USB cable for the tablet. Edit: apparently HP does have a cable for it, but it may be difficult to find and isn't cheap.

Here ( http://forum.xda-developers.com/showpost.php?p=51682931&postcount=8 ) is the method of rooting the SlateBook by using the Micro-USB dedicated cable (HP spare part number 728141-001, sold separately). It involves the use of several fastboot commands.

@SopalajodeArrierez that is what you need then. There is no way to access fastboot except from another PC.

Well, thanks for your opinion. I suggest for you to correct your post, since there is some USB cable (expensive, but it exists) for this tablet and there is a way to access fastboot for this tablet.

@SopalajodeArrierez thanks. It is funny that HP doesn't even list this cable anywhere in their support docs. I am glad there is a way, but it is a very poor design by HP.

I know I'm late with this answer, but for the future readers, you can unlock your bootloader on-the-fly with an app. Assuming you have root access and a standard unlockable bootloader (fastboot oem unlock), you can use Trickster MOD. You can see its XDA thread for more info.
Look under the "Tool" sub-menu and toggle "Bootloader Lock State". If you're even still keeping up with this post, how do you have TWRP with a locked bootloader?

XDA Thread: http://forum.xda-developers.com/showthread.php?t=1768315
Link to app on the Play Store: https://play.google.com/store/apps/details?id=com.bigeyes0x0.trickstermod&hl=en

No, there's no way to send a fastboot command from the device itself. When the device is in fastboot mode, it's a very dumb device and can't even give you a shell or turn on the Wi-Fi. The fastboot program is the only way to send it the command to unlock the bootloader.

Samsung Galaxy S4 only boots for 5 seconds, then dies
Yesterday I was using my phone, and suddenly it shut off. I tried the power button, but it wouldn't turn on again. I then took the battery out, and put it back in. Immediately, the phone vibrated, and displayed the Samsung Galaxy splash screen (this happened without me pressing the power button). After about 5 seconds, it shuts off, and I have to start the process over again. I tried booting in safe mode, and recovery mode, and the same thing happened. Interestingly, If I take the battery out, plug the phone in, then put the battery back in, the phone doesn't automatically start, but it still doesn't boot either. I tried changing the battery, but that didn't seem to make a difference. Initially I thought it might be something wrong with the power key, however, I would expect that if that were the case, it should be constantly restarting, not shutting off and staying off.
What could possibly be causing this? Is this more likely hardware or software, and is there any way to fix it that isn't just replacing it?

I think you're right about the power key problem. Samsung phones don't restart like that unless you let go of the power key. I've had this problem myself - although the issue disappeared after sixteen hours.

I don't have a solution for you, Ephraim, I just want to confirm that I'm having the exact same problem as you described right now. There was hope at one point, though. I had the phone just lying there with the battery in it, and it randomly booted up without my intervention and worked properly. It last about 2 minutes, then turned black and off, and the same problem is happening again...

Galaxy Note II slow due to lack of memory?
I have a Galaxy Note II and it's too slow due to low memory, I bought a 16 GB memory card and it still is slow, what to do?

@eldarerathis I translated it to English (but still it isn't a very good question), can you reopen the question?

Adding an SD card is unlikely to affect the speed of a slow device; low memory messages are related to RAM, not storage.  More likely you have one or more apps running that is eating up CPU/RAM, as the Note 2 has excellent hardware specs and is unlikely to be "slow" except under exceptional circumstances.

The speed of your device relates to the RAM not ROM. RAM of NOTE2 is 2GB and RAM is not expandable.
RAM is the memory where all your foreground and background process resides. If RAM usage in your device is very high, uninstall or disable unnecessary applications. And install a Task Killer and schedule it in crazy mode at every half hour. It may increase the speed of your system.
You can manually clear your ram from task manager. Long press home button then tap on left most option which is task manager there select ram tab and tap on clear Memory.

I wouldn't recommend a task killer since most of them just screw up Android's memory management even further.

Additionally, clearing RAM and doing round-house-kicks with a task killer often slows down the device even further – as killed apps do auto-restart, and have to load all their data back to RAM. Result: More I/O, faster battery-drain – and no relief. Task-killers are for getting rid of hanging/havocing processes, not for "cleaning" RAM.

BATTERY got wet, then won't work!
What is that little sensor for on my LG cell phone that lines up with the battery?
Went the battery got wet, it quit working.  What is that little round sticker on the battery that lines up with that sensor?  Can it be replaced?

You might be able to get a replacement battery.  That's much cheaper than buying a new smartphone.

Does Android keep activity logs or save keystrokes?
I want to know whether Android phones records activity logs of what I have done in a whole day. I've already checked that there is no Carrier IQ.
Is this true that after switching off the phone all activity logs vanish? Does my Android phone keep saving what keystrokes I typed? (I'm using Samsung keyboard.) Do all activity logs and keystrokes gets upload to my Google account server or any other account like Samsung?

No, stock Android doesn't record everything you do in a day. There are a few things to bear in mind, though.
First, because Android is open-source, the manufacturer, and your carrier if you bought the phone from a carrier, can change the OS however they like. They might have changed it to add a log like you describe, so though Android itself doesn't record all your activity, I can't say for certainty whether your phone does or not.
Second, there's nothing to stop individual apps keeping records. For example, Chrome keeps a record of what websites you visit, and if you have "Web history" turned on, it syncs that information with your Google account. Other apps might use analytics to track what you do inside that app, and send that information to the app's author. Apps have access to a lot of information, even some information not directly related to the app (such as what other apps you have installed), so you have to trust the app not to do this.
Keyboard apps are another example of this. They learn what words you have typed, and maybe collocations of words (for example, if you type "Cambridge" followed by "Circus", it might save this in order to better predict it in future). Whether this information is uploaded to any server depends on the particular keyboard app.
The log you might have heard about in Android isn't an "activity log" at all: it contains debugging information for developers to see what apps are going, and to help find and fix problems. It's not intended to log what you're doing, though sometimes the information in there could be used to identify particular actions, and what apps you're using. Exactly what information this log contains depends on the phone you have, and it differs from app to app.
As you've mentioned, the log is only in memory and so it's lost when the device reboots. It's also a fixed size (the exact size is different on different devices), so over the course of a day newer log entries will continually overwrite older entries.

The  above does give your answer I am only going to explain it in brief
Following are some of the ways through which key logging is done.
Google:-Whenever you open the Google search and type your search it will be stored for the future to do things like auto-complete, display advertisements in your phone etc.
T9 dictionary:-Whenever you enter a custom word more then once it will be stored in the dictionary by default. The input could be anything passwords ,bank account no's ,name anything.
It's for the ease of the user these custom words are stored. Next time when you just enter the first letter of the custom word then the remaining word get's displayed for selection. Thereby relieving the user the need to type the whole word manually.
While installing apps from the play store or any other source from outside always make sure that the permissions required suits to the kind of application it's made for.
For ex:-There are some apps like flash light which would require permission only for the camera to display the flash but as you would un mindfully go ahead and install then your phone's data could be distributed to third party's because if you have carefully viewed the permissions required then it would also ask for some unwanted permission (view contacts/call log etc.) which is not at all related in its functionality or usage.
In this way whenever you call or whatever number you have dialled would be accessible to the flash light app and will be secretly transferred to its server whenever there's a connection to the internet.

Is it okay to delete CWM backups after copying them to my pc?
Recently, I installed CWM (Rom Manager) and a custom recovery in my Xperia SP. Then I went to Rom Manager and pressed 'Backup Current ROM' which took me to a screen that backed up everything. Then I used adb pull /mnt/shell/emulated/clockworkmod/backup to copy that backup into my PC. Now, the copied files in my PC are:
Now,

First thing, from what you see, can you tell me if the backup is complete (it is about 2 GB)? Well, this is the content of the recovery.log file.
Can I delete the backup present in my phone(because it is occupying a
large amount of space ~2 GB)? Or should I keep it there. I have
heard of mysterious evil things like bricking, bootloops etc.
(which I am REALLY scared of). And in many places I've found that
the best way to recover from those scary things is to use the backup
of the ROM. Now, please tell me that if such a disaster happens to
my phone, can I transfer the files from my PC to the phone or do
they need to be in the phone for me to be able to recover from the
disaster?

You can theoretically delete them without hesitation after moving, but do keep in mind that CWM depends on file integrity checks like MD5 to see if your images have not been modified since the day you took a Nandroid backup. There are some cases when phone-to-PC transfers  ruin the MD5 signature1 and therefore prevent CWM from restoring the Nandroid backup in the future.
If you do every step in ROM installation exactly as said in the instructions listed on your ROM webpage and you're not going to do anything daring after successful installation, chances are you're not going to need that Nandroid backup anyway. But it's always better to be safe.

Exporting GPS data from app-internal database
I am trying to create a height profile from the GPS positions I recorded last week while hiking. I used the App GPS Logger (now called GPS Offline Logger) on Android 2.3.5/Samsung  GT-S5570 and managed to have it create .kml-Files, and from the second day on, also .gpx-Files. Now, the .gpx-Files contain a lot more information (like accuracy and height) than the .kml-Files (Which are just a <linestring> with a list of coodinates).
Is there any way to have the app create the .gpx File for the missing day or can I (maybe using ADB via Ubuntu) directly access the application's internal database and get the data from there? (If I click "show logs" and then long-click, "show details" twice, all needed information is displayed.)

Ok, so the program still produces a logfile called location_log.txt with all of the important data. I wrote a script in python to export it:
#!/bin/python
#
import codecs, os
__author__ = 'lukas'
path = "/path/to/the/folder/"
ins = codecs.open(path + "location_log.txt", "r", 'iso-8859-15')
array = []
for line in ins:
    linenew = ""
    count = 0
    for char in line:
        linenew += char
        count += 1
    array.append(linenew)
ins.close()

Deleted mobile number keeps returning Galaxy S4
I've got a Samsung Galaxy S4, running ICS.
I keep my details including my own mobile number in my contacts.
Whenever I go to look at it, there's another number included (I think it's one I had a while ago) which makes it hard for me to remember which is mine!
I've checked my Google account and that only has one number for me.
I delete the number, but if I check a few days later it's back - any suggestions how I remove the number?

Are you syncing your contacts with anything else? Facebook, perhaps?

As far as I can tell I'm only syncing with my 2 Google accounts (which only have one mobile number for me) and the Samsung account stuff you can't remove. I disable everything to do with Facebook.

still a problem

Starting the android emaluator in ubuntu?
I created an avd of galaxy nexus with Intel atom x86. Now when I start the device, it gives me some cards to swipe. At last there is a card saying "To dim screen, cover it with your palm."  How do I do that? I am not being able to get the android menu and everything. And if I use arm the device wouldn't start and becomes black.

Can you provide a screenshot of what you're seeing?

Are you sure the device is not Android wear?

How can I safely lock my screen without password?
I have bought a new android phone (Samsung GT-S7710) with a new android system. It has a lot of useful features and lots of flaws caused by too hasty development.
One of these flaws is the lock screen. On my android version (4.1.2), the lock screen is unlocked by sliding anywhere to any direction. This often happens in my pocket and causes lot of problems (contacts getting deleted, random calls and so on).

I still don't understand what was the programmer responsible for that thinking about. It's just as ridiculous as having a keyboard phone that says "Press any key to unlock!".
Of course, I could set up a password. The thing is, that my previous phone has returned to me, because there was no password and the man who found it could contact my relatives.
I actually see no reason to have a password in my phone anyway. I often borrow it to other people and password is just annoying.
So is there some lock-screen patch? Can I install some application that handles screen locking right? Can Android be updated to a fixed version? I don't want to root my phone though.
For those who don't get it from the above: How can I lock my screen so that it won't unlock in my pocket easily? I'm looking for a complete solution.
Oh and also, the top bar is not locked at all. It keeps turning on Mobile data and wasting my money (for me, mobile data is an expensive thing I want always turned off)

I'm confused at what's wrong here... This method is exactly how Android lock screens work, cross-device... My LG G3 is just the same - you swipe any direction.  What are you trying to accomplish with "locking"?  And as a second comment, the "top bar" you're referencing... Do you mean the notification bar?  It's not using data...  On all phones you can pull down the notification bar if there's no password on the lock screen.

Well, I'm complaining that it unlocks in my pocket all the time. That's total bullshit. It happens very often to me. I talked to other users about it and they all just use the password as a workaround.

Is my keyboard phone analogy so hard to understand?

Chill out, bro. I understand. The best you can do is download a lock screen replacement, and see if there's a method in any of those apps have a method you'd prefer... What is ideal for you? Do you have a method in mind that doesn't require a password?

To give you a proper solution, it'd be great if you could say exactly what you want..

I have no specific idea. I'm not the one who's paid to develop a practical mobile OS. I just want something that doesn't take any actions while in my pocket - like turning on mobile data and wasting my money (I have a very bad tarif).  I really wonder what you don't understand on my question.

Being rude isn't going to help at all, bud. I completely understand. However, to properly assist you in finding a lock screen replacement, we need to know what you want. For example, you could say "I like how the iPhone unlocks; requiring a swipe in a specific row." And on that topic: requests for a specific app are off topic here. Simply searching in Google Play for "lock screen" will return a plethora of lock screen replacements. You have to understand that this is how Android works - it's not a bug, and not improper programming. Therefore, there is no "patch" or "fixed version."

Two options: search for Go Locker and install that. Or turn your screen away from your leg while in your pocket.

If you want your phone to NOT turn on in your pocket but still be able to have someone find your phone and identify it as yours, here's what I recommend.

Set your phone background message (the text that can display on your phone lock screen once enabled or edited) to your name and email address. Anyone who finds your phone can then contact you if they don't just want to steal it.
Enable a pass code, pattern lock, or password on your phone.

You will never be able to disable the emergency call option from your lock screen (unless you install a custom ROM), but this should help cut down on the butt dials and other issues.

So there is no safe lock without the password? Did Android developers at least explain, why they don't use the slide lock (which never failed me) any more?

Chat Bubble for WhatsApp Messenger
I was wondering if it is at all possible to get chat bubbles(similar to the ones used on facebook messenger) for whatsapp messenger on my nexus 5. Is there an app I can download, or a process that will allow me to get chat bubbles like this for whatsapp?
These are the chat bubbles I'm talking about (the little heads)

You can install the app Whatsapp Chat heads I am not sure if it runs on Nexus 5, or that it shows Chat-heads or just the name of the chat.

Who is the designer of the app? Dregens Teknoloji?

Try this app:
https://play.google.com/store/apps/details?id=com.stallware.dashdow.whatsapp.lite
and see this article:
http://trendblog.net/how-to-get-chat-heads-whatsapp-android/

Dunka, you can install my app, WhatsBubbles, which provides a nearly identical user experience and allows users to preview, open and respond to conversations.
Give it a try!

Please confirm what relationship (if any) you have with this app: it's OK to recommend your own app on this site, provided you're honest about it.

Yes, I am the app's developer. I did not mean to be deceptive, I am just trying to promote my app. I will update my comment.

Whatsapp For Nokia X
I wanted to know that how can I acquire Whatsapp for my Nokia X. My family and friends are both on Whatsapp and it causes a communication gap between me and them if I don't have it. I want to keep this mobile phone for a  I open to all suggestions on how to acquire it

Not sure who voted to close, but it's a legitimate concern, since Nokia's Android phones do not have access to the Google Play Store.

Since your Nokia X doesn't have access to the Google Play Store, you will need to download and install Whatsapp manually.

Enable side-loading of apps on your Nokia X by navigating to Settings -> Security and enable the Unknown Sources option.
Download the Watsapp APK directly from their site to your computer.
Transfer the apk file you downloaded onto your Nokia X by connecting it via USB cable and using a file manager, send it via Bluetooth, or copy it to an microSD card and insert it into the phone.
Run the pre-installed ASTRO file manager and locate the file using the search option.
Tap the file to run it, which will start the installation process.
Follow the on-screen instructions to complete the installation.
Important step: Modify your phone’s date to (or just prior) 2nd of August of 2014 (don’t worry you will change it back to the preset date afterwards.)
Launch Whatsapp like any other installed app on your Nokia X phone, and complete the initial set-up.
At this point you will most likely get a message saying that this application is "not supported" on your phone.
Exit WhatsApp when it says that your device is not supported back to the homescreen.
Uninstall the official Whatsapp application by long-tapping on the WhatsApp icon and tapping on the red cross.
Now download WhatsApp Plus from here and install it using the same method as the official app (steps 3 through 6 of this guide.)
Open Whatsapp Plus app and go through configuration steps. Make sure to use the same phone number as you used in the original WhatsApp, otherwise it will not work.
You can now revert the system's date back to the present date and still enjoy WhatsApp.

You can now use Whatsapp plus to connect to your Whatsapp contacts.
Sources: 1, 2.

Now, it is available for download from the default Store app in Nokia X. The Nokia  Store was replaced by Opera Store earlier, however, the store contains limited apps. A third party app store like 1Mobile Market can help finding more apps.

Bluetooth keeps turning on
I have seen this problem on a Nexus 4 and Nexus 5. Bluetooth is switched on unexpectedly. It can be turned off, but will come back a minute or so later.
Googling around, it seems that this could be due to a misbehaving app, but there doesn't seem to be a good solution for finding out which app.
Is there a way to find out what is responsible for reactivating Bluetooth all the time?

If it is of any use, I captured some of the adb output after disabling Bluetooth.

Quick question, I am presuming this is for "Stock Rom" for both Nexus devices?
If so, could you run adb shell dumpsys meminfo.. It may as well be a package you installed on yourphones which could be the culprit.
FYI - I performed the same tests on my Nexus 5 - rooted phone with stock ROM. and all is working for me.. however I find this log line interesting where the state change from 13 -> 10 when I stopped the Bluetooth service...
D/BluetoothManagerService( 1683): Bluetooth State Change Intent: 13 -> 10

@Rushnosh, yes this is stock Google Android on both devices. I'll do the memory dump later and add what I find from that to the question.

ok, also Andriod build version if at all possible?

Got the State change ID's also:
12 = STATE_ON - BT Device is on
10 = STATE_OFF - BT Device is off
13 = STATE_TURNING_OFF - BT Device is turning off
11 = STATE_TURNING_ON - BT Device is turning ON
More info here:
http://developer.android.com/reference/android/bluetooth/BluetoothAdapter.html#STATE_TURNING_OFF

Now just compairing with your logs to mine here I noticed there is a warning when trying to clear out your Blue Tooth Devices under the Logitec Keyboard message: D/CachedBluetoothDevice(14368):  Clearing all connection state for dev:Logitech MX5000 Keyboard W/ContextImpl(14368): Calling a method in the system process without a qualified user:
Dont know if this is releated but restarting your phone, perform the on/off BT test to see if normal phone works, then connect your keyboard to see if it is your logitec not handling the disconnection.

To answer a few questions, I have Android 4.4.4, build KTU84P. The Logitech keyboard is several kilometers away right now, so unless I've really underestimated the abilities of Bluetooth, that shouldn't be causing a problem. (The Nexus 5 has never seen the Logitech either). Also - thanks for your time so far... this is really appreciated!

Did you at least try restarting your phone and performing the test I requested but?

Sorry about that, ran out of time last night. I restarted and now the problem has gone away! Which means we don't get an answer as to what was causing that. If / when the problem comes back, I will perform your test on the phone. Thanks for the guidance!

It process of elimination my friend :) ... at least the problem does not stick when you restart your phone, so now we got a baseline to work with. Now try an number of things such as ... reconnecting your keyboard and do some tests... if all works well try another thing.. from examining your logs you had a number of different BT peripherals to choose from. So give it ago, and when the problem persists, please list down the steps you have done to replicate the issue, and with this you can forward your findings to the correct group of Developers :)

And dump your logcat logs as well ^_^

It was the Firechat app for me.  It'll be one of the most recent apps you installed if the Bluetooth started turning on out if nowhere.

Suggest you post this as a comment rather than as an answer, since it may not be applicable in OPs case

Thanks! Did the job for me. Been looking for weeks of what was wrong!

I had the same symptom, and disabling "Bluetooth scanning" in location services resolved it:
https://stackoverflow.com/questions/34414216/using-bluetooth-scanning-for-location-accuracy-android-m

The question was posted on Aug 2014 when there was no Marshmallow yet, so I can't think if this would help solving the issue...

I'm on Marshmallow currently and I'm still getting this issue.

You can find out what is activating bluetooth by going to Settings -> Connections -> Bluetooth -> "..." -> Bluetooth control history.
In my case it was the bike rental app for Paris "Velib" and sadly, there seems to be no way to stop it activating bluetooth via permissions settings.
My phone is a Samsung GS7 with Android 7.0.

I had the same problem.  The app named Automatic that connects to a dongle that plugs into the OBD port of your car was to blame.  I hate the app.  I just use it occasionally to read check engine codes. Uninstalled Automatic and all is well.  It's usually a misbehaving app that is the culprit.

I had the same problem. This worked for me.
Settings ~Application~All~Bluetooth. The disable button was not highlighted so I just cleared all data. I did the same for bluetooth share. Then I tried turn Bluetooth on an off several times to see if it would stay off and it did

I had the same problem and it turned out to be an app containing incorrect codes that kept searching for Bluetooth devices in background even if the app was closed (it was a BT Messaging app).

What do Online and Offline mean in Viber?
If my bf's viber shows he's online and then in the middle of the night it changes to offline, what does this mean? Does it mean that when he's at home and within reach of the internet it shows him to be online if his Viber app is active? And does it mean that he has gone out of range of the internet if his Viber states he's offline? (He has a Samsung Galaxy Fame.)

"Online" means that Viber is running in the foreground or background (the user is available for calls or messages). When the phone has no internet connection, or the user manually used the "Exit" option inside Viber, this changes their status to "Last online at..."
In some cases, depending on the mobile kernel and software, the user uses something like Power Saving Mode, so after the idle time, the Wifi is turned off or some background application is turn off ... so Viber is turned off, your bf's viber state is also offline.

What is the default chinese font in Android?
What is the default Chinese font in Android and where are they stored so that I can get the font files?

On Android 9 it's Noto CJK, e. g. "Noto Sans CJK JP" font family (located in /system/fonts/NotoSansCJK-Regular.ttc). There is no DroidSansFallback.ttf anymore.

Fonts are always stored at /system/fonts. By changing the system font to Chinese, and looking in that directory, you may be able to find the font.
Hope this helps.

I believe the font is called Droid. A few variations (sans, sans mono, serif, condensed) are available from DroidFonts.com, though it should be noted that Droid Sans may be the only to contain Chinese characters.

Each of the Droid fonts was custom designed by Ascender and optimized for on-screen legibility with the Android platform. ...
[Droid Sans] contains over 43,000 glyphs and includes support for Simplified Chinese (GB2312), Traditional Chinese (Big 5), Japanese (JIS 0208) and Korean (KSC 5601). This font uses the Simplified Chinese ideographs for shared Unicode code points.

Droid is a family of fonts and your usual droid font doesn't have Chinese. Particular Droid font that has Chinese is DroidSansFallback from the answer below.

The name of the font is DroidSansFallback.ttf it is located in /system/fonts/

Support for CJK is provided by the Droid Sans "fallback" font. This font contains over 43,000 glyphs and includes support for Simplified Chinese (GB2312), Traditional Chinese (Big 5), Japanese (JIS 0208) and Korean (KSC 5601). This font uses the Simplified Chinese ideographs for shared Unicode code points.

There are no other font with Chinese in a regular western Android phone therefore DroidSansFallback.ttf is used to display Chinese.

How to renew Google Play Music All Access from Android?
I got the 30 days free trial for Google Play Music All Access, but I cancelled it. I'd like to renew it. How can I? I can't find a way. Here's an image:

If you canceled the trial and want to renew the TRIAL, I think you'll have to wait for another offer.
If you want to renew the actual service, go to Play Music, settings, Subscribe to All Access.

Will Google play store auto update in future if I install latest store APK manually for now?
I'm desperately waiting for play store to update to 4.9.13, now it's been three weeks since update release and I'm losing control now. I want to ask that for now if I update play store manually with the latest APK from android police website, will I receive next update as an OTA or will I have to update it manually? And will there be any problem if I install play store update manually with APK?
Thanks in advance!

Yes, It will :)
I do this all the time when a update comes up and available to my phone.
I too am using Play Store 4.9.13.
Even if this doesn't work out, you can uninstall updates in app settings in your phone.

Download notification not showing after factory reset
I have an Asus Zenfone 5.
Usually when I am downloading a file, my mobile will show the download in the notification pane. After performing a factory reset on the device it is not showing the download notification. I think the built in download manager is damaged after factory reset.
How can I fix it?

A factory reset does not touch the system partition, so built in apps such as the built in Download manager will not get touched. Perhaps you used a different web browser before the factory reset you performed, and that had better download management than the one you are currently using.
If you download ES File Explorer from the play store, you can use the module in that app called ES Downloader. This is a good way to check downloads in progress in a nice dialogue box

Nothing is wrong with this app just follow these steps definitely your problem would be fixed.
Go to setting
Open uc browser
Just click on notification check box
That's it , enjoy

very easy problem. go to setting select app switch to all and find Download Manager. you will see unchecked Show Notification. Check that with your nose. :)

That does tend to work, yes.

Go to Settings->Application Manager->Click the Menu button->Sort by size/Reset App Preference->Click Reset App Preference.

Can't set date via shell
I've tried
date -u 1407697765

output:
time 1407697765 -> 1407697765.0
settimeofday failed Bad file number

and
busybox date -s @1407697765

output:
date: can't set date: Operation not permitted

I don't feel that I'm doing everything right (especially when date -u) but it looks like I have no permission... I'm trying it through adb shell
Why do I get these errors and how to set date through shell?

Only the root user can set the date. If your phone is already rooted, just type suEnter to get into a root shell, then the command you want to run.
If your phone is not already rooted, you'll need to get root access first. See How do I root my Android device?

I thought that adb shell uses root by default ><

The following worked for me (once you have root permissions):
adb shell settings put global auto_time 0 && adb shell date 010219302018.00 set && adb shell am broadcast -a android.intent.action.TIME_SET

auto_time -> This is to switch off automatic syncing of time.
To reset the time back to syncing with the network, do:
adb shell settings put global auto_time 1 && adb shell am broadcast -a android.intent.action.TIME_SET

Issue the following commands:
adb shell date -s YYYYMMDD.HHmmss

or
$ adb shell
$ adb root
# su
# date -s YYYYMMDD.HHmmss

Lock screen is not changing after updating to Android 4.4.2
I have updated my Samsung Galaxy Grand 2 to 4.4.2 and after that I'm not able to change my lock screen wallpaper. It always shows a wallpaper which is already in the device which has red background. Home screen changes every time whenever I want to change but lock screen remains the same. But if I put a live wallpaper as my home and lock screen it applies to both home and lock screen. Please suggest something how I would be able to put any pic from my gallery as lock screen. I changed the lock screen through settings also but no use.

I have a HISENSE SERO7 e2371 tablet here. I could not get the lock screen wallpaper to change at all.
Finally figured it out and thought I would post it here just in case anyone is looking for a solution.
I went into Settings → Security → Screen Lock and changed  Hisense to Slide.
It seems that it was an issue with the Hisense custom lock screen they provided, so this may be  same on other devices where the manufacturer has added a custom lock screen option.

just a quick search results show me that you may try power off and removing the battery some people face the same issue after update

Just change unlock effect..
There you go.. You can change lock screen wallpaper on Grand 2.
Setting-device-lock screen - unlock effect. Change it.
Thank you

OP already stated: I changed the lock screen through settings also but no use – so how is your answer different?

I think it is software glitch on the Grand 2. To solve the problem, try to transfer the SIM 2 to 1. You may be able to change the lockscreen wallpaper.

Try to transfer the SIM to what? Why would that affect the lock screen?

Microsoft Outlook.com app notification
Some information:

I have 1 gmail account for my business/work related emails only I
have an outlook.com account for my personal emails
I have another gmail account for non-important things i.e. newsletters and freebie
sites and other 'spam' type mail.

I would like to use the gmail app on my phone for the business emails only and
I want to use the outlook.com app to take care of both personal and non-important emails.
Steps taken so far:
I have installed the outlook.com app on my nexus 5, running the latest android.
I have then added a secondary account to it, via the web interface on my computer. This is my second gmail account that is used for non-important things and is linked via the POP3 settings, and shows up as a separate folder next to the inbox/outbox in the outlook app.
The app is configured to notify me by both sound and vibrations (both options checked in the settings) - and it is configured to receive push notifications.
However, the app behaves quite strangely. For the main account (my @outlook.com address) the push notifications are pretty instant and the phone vibrates/makes a noise. For my secondary account (gmail linked via POP3) there is no notification, I see these updates when I open the app (it shows unread count). How can I make the phone notify me of ALL messages that appear in the outlook.com app.

Why dont you just let the gmail app notify you of your secondary emails as a push notification?

I had that setup initially (Gmail app with main account, plus secondary account), but then my work inbox gets clobbered with a few hundred non-work related emails, amazon newsletters and facebook notifications over the course of a month or so. Deleting them as they come and actioning them on the spot gets really difficult in the long run. I need to keep the accounts separate.

Also note that outlook only checks your POP3 account once every 30 minutes

I mean, have the two accounts in the gmail app. Then the inboxes are kept separate and you can easily switch between the two :)

Not true. There is an option, to set the update time to manual, 1 hour, 30 minutes, 15 minutes and push notifications. Regardless of which option I choose, the phone does not notify me of any incoming emails to my second account. I can see 3 unread emails in this folder, right now, but I had no notifications of any of them.

Ah, having 2 gmail accounts in my gmail app - good idea, the notifications would work, but then I lose the ability to manage them both from my web browser - without logging out of one and logging into another. The way I see it, I shouldnt have to find a workround, the outlook app should just notify me when there is a new email in either my outlook account or my gmail account.

The outlook app doesnt support push notifications on POP3 accounts according to the webpage i just read

You could still have the POP3 or email forwarding set up to see your emails in your outlook account on your desktop. The only problem i can see with this though is that you'll have to process all the emails twice

On gmail on your desktop you can click your profile icon in the top right corner, then click "Add Account". Then you can add your secondary account, and then to switch between the two accounts easily, just click the profile icon, and then click your other account which will be listed there

You can't have email push notifications over POP3. It's an old protocol and simply doesn't support push. It doesn't matter what client you use or what kind of mail server.
If you can set up Outlook to access Gmail through IMAP instead of POP3, and if Outlook supports IMAP IDLE for push notifications, then you'll get push notifications. Otherwise, you might have to use a mail client that does support IMAP IDLE, such as K-9 Mail.

So, if I do not use push and do an automated sync every 15 minutes, the app should notify me of new emails to my second account? As I can't seem to even get it to do that.

Well, after a day, it is still syncing emails every 15 minutes but I do not get notified of them. Nothing in the notification bar, but when I go to the app, it shows emails in the secondary inbox. Notifications only appear for incoming emails to my outlook.com account.

@Husman I don't use Outlook, but most email clients have separate notification settings per account. Could it be you just need to turn on notifications for this account?

I have checked and double checked the settings. Having read a few threads on the internet and some of the review of the app - it appears this functionality is broken.

What is the use of Automatic update of date and time when i have to manually enter it?
Step 1-I have checked the Auto update date and time and Suppose I remove my battery and then place it due to some phone lag. On starting it shows the default date and time (factory set date,time) .
Step 2-As I had previously enabled the auto update of date and time the phone continues to show the factory date, time .
Step 3-I cannot change date, time because the option is blacked out. So for that I un-check the auto update date and time. Set it to today's date and time  and save it.
Upon saving the phone restarts.
If this is the case then what's the use of Automatic update of data and time when I have to manually enter the date and time for my region.
For what reason does the phone restart again?

If it's restarting when you set the date and time, there might be a bigger problem at the root of this. What happened exactly?

When you set the Date/Time to automatic, it should set, then maintain, the correct time and date by using a server (assuming you have internet access). It does not need to restart at that time.  When you remove the battery, does it default to automatic for date/time?  Also, a simple restart should be sufficient to fix problems; removing the battery is when it won't respond to any keys.

@Marty ,Dan plz check the update.I have simplified the process in steps

If you have an internet connection, then something is wrong with your phone; it should not work the way you say it is.  I think I would do a factory reset, unless you can confirm that this problem is somehow normal for the device you have. But if it is normal, then it is a broken design.

@mar can you explain what exactly does the automatic update do

The automatic time/date does exactly what you would expect - it sets and maintains the date and time no matter what time zone you are in, instead of your needing to set it.  Even non-smart phones could do that, and I have never needed to set the date and time for a phone that was provisioned, even without internet.  I'm not sure if smart phones need the internet or not, to be honest, but I mentioned that just in case (I'm assuming it's an Android phone).

Your carrier should be able to provide the time and date even without a data connection. Most cell phone towers have a GPS receiver which uses the GPS data to sync it's clock, and forward this to the devices when they register to the network. Nowadays some towers might have a NTP sync instead of the GPS but the same principle still remains.
It seems to me that there is an error in saving the correct time and date on your device, which prevents the time from being synced from the carrier to your device. I'd suggest a factory reset (and/or reflash of you're on a custom ROM).

I am on the Stock ROM (Android 4.1.2) and I don't think doing a factory reset wouldd do any good because I am currently in SE Asia where most of the towers are a simple receiver and transmission only.

Still, the phone shouldn't restart when you set the time manually.

Airplane Mode Timer that LOCKS
I have found airplane mode apps where I can set a timer for when it comes on. However, I can't find anything that requires a password to turn it off. I need to set it up on my friend's phone for his son so that it forces the phone into airplane mode every night so his son goes to bed. I've tried various Parental control apps, and they suck. Also, it would be useful to have the option to manually turn the service off by sending an SMS from another phone.
Please, don't tell me that my friend needs to take away his son's phone at night. I agree. But it's not my kid so I can't do it myself.

You don't need a password for anything here, neither you've to worry much that the Airplane mode would get disabled by the kid.  Of course, if the kid is smart then s/he would find a way to by-pass the restrictions  imposed using the following solution.
For the solution, you need to use an automation app app like Tasker (paid but trial is available) or MacroDroid (free/Pro). I've demonstrated the solution using the latter because its free version does the job.
Note: Device needs to be rooted.

We would create a macro which would make sure that if the kid disables Airplane mode by any means the Airplane mode would get turned on automatically as long as the time period remains true.

Install and launch MacroDroid.
Tap Add Macro  → Airplane Mode Changed → Airplane Mode Disabled → OK.
Under Add Actions, tap Airplane Mode On/Off → Airplane Mode On → OK → (leave options unchecked) OK → proceed.
Under Add Constraints, tap Time of Day → choose Start Time and Stop Time i.e. for the time period where you want Airplane mode to get enabled and remain active until another time is reached, such as 22:00 to 05:00 → OK → proceed.
Name the macro as Persist Airplane Mode → OK.

Your macros would show up under Macros at the default page of app.
Create a new macro to start the Airplane Mode for the time where you want the kid to sleep or go to bed:

Tap Add Macro → Day/Time Trigger → choose Days of the week and Time of Day, such as Saturday, 22:00 → OK.
Under Add Actions, tap Airplane Mode On/Off → Airplane Mode On → OK → (leave options unchecked) OK → proceed.
Ignore Add Constraints and name the macro as Start Airplane Mode.

The Airplane mode can be turned off easily after the device is rebooted and before MacroDroid is started from startup. MacroDroid wouldn't activate the Airplane mode automatically after reboot unless told to do so.
To make sure that Airplane mode gets enabled automatically after reboot, make the following macro:

Tap Add Macro → Device Boot.
Under Add Actions, tap Airplane Mode On/Off → Airplane Mode On → OK → (leave options unchecked) OK → proceed.
Under Add Constraints,  tap Time of Day → choose Start Time and Stop Time i.e. for the time period where you want Airplane mode to get enabled and remain active until another time is reached, such as 22:00 to 05:00 → OK → proceed.
Name the macro as Activate On Boot → OK.

Now, create a final macro which would disable the Airplane mode at a particular time:

Tap Add Macro → Day/Time Trigger → choose Days of the week and Time of Day, such as Saturday, 05:00 → OK.
Under Add Actions, tap Airplane Mode On/Off → Airplane Mode Off → OK → (leave options unchecked) OK → proceed.
Ignore Add Constraints and name the macro as Stop Airplane Mode.

You also need to activate MacroDroid as Device Administrator so that it can't be force-stopped or uninstalled easily.

Go to Settings → Security → Device Administrators and choose MacroDroid in it.
Also, go to Settings → Apps → MacroDroid → uncheck Show notifications so that its icon and notification doesn't remain visible or persistent.

I've not tested the SMS feature in MacroDroid but I've no reason to believe that it wouldn't work. Give it a try.

The free version of MacroDroid limits to five macros.

Is Microsoft charging for its patent from each Android device sold?
I read here that Microsoft is cashing Android handset ODMs for some patents that are allegedly used in their Android handsets. Why is Microsoft able to do that? Is this a HW or SW-based problem?

I'm voting to close this question as off-topic because as per [help/on-topic] legal questions, such as "Will X void my warranty?" are off-topic.

The list includes 73 standard-essential patents, but there’s also 127
  patents that Microsoft claims are implemented in Android. Some on the
  list, as Ars Technica notes, include patents that Microsoft acquired
  as part of the Rockstar Consortium to bid on patents from Nortel.
  ...
  Microsoft is estimated to earn as much as $1 billion a year from
  Android-related licensing revenue.

ref : http://www.theverge.com/2014/6/16/5813710/microsoft-android-patents-list

Yes. Microsoft takes a small amount of revenue on OEM's device it has reached an agreement with. This includes Samsung, LG, Sony, etc. They are able to do it because they hold key patents to some of the methods most smartphones use to function. This includes patents related to interaction with user and network operations. Licensing fees for different OEM is different and not all device violate same patents. so it is both a software and a hardware problem.

Error: Duplicate Provider Authority
My android phone is asking me to update Google Play Store services, however when I hit update it will stop with the Duplicate Provider Authority error.  Ive noticed that others who had this error with game apps, etc... could just uninstall and reinstall the app, however I cant do that with Google Play Store.  Any suggestions?

Which phone do you have, and what version of Android is it running? Is it stock, or rooted/custom ROM?

Are you sure this is a genuine message, and not a scam from a website or a malware app on your phone? "Duplicate Provider Authority" is often a sign that a package is masquerading as a different one. Please describe in more detail how your phone is "asking you to update". Include a screenshot if that helps.

Why can't I access google.com when tethering?
I am paying my wireless carrier (MetroPCS) for the "hotspot" feature, which is required in order for me to tether. However, strange things are a happening....
I can't access google.com, although I can access it via IP address - 208.54.90.53. Which leads me to believe it has something to do with DNS resolution.
HOWEVER
I can access android.stackexchange.com directly.
BUT
I can't access facebook.com either directly or via IP.
... I've tested this on multiple laptops, and the issue is the same. What in the world is going on?

Can you access these sites from your phone?

Yep I can access them fine

Then most likely your laptop isn't receiving the DNS settings from the phone, or isn't using them. You need to check the network configuration on the laptop, and check it's using DHCP and not a static IP address.

On my laptop (Windows 7) I checked Local Area Connection > Properties > Internet Protocol Version 4 > Properties > Advanced and I see that under "IP Addresses" It says "DHCP Enabled". Do I need to check something/somewhere else?

What DNS are you using? Have you tried using Google's public DNS (8.8.8.8 and 8.8.4.4)?

I had it set to "obtain DNS server address automatically", but the issue still occurs when I try setting it to Google's public DNS.

Once I disconnected my other LAN and Wifi connection that were connected but had no internet, it worked. Before I had no FB or Google as you say. Must have been a conflict

I think that gives me a feel that your ISP provider may have blocked some sites. Why don't you try contacting your ISP vendor ask for a resolution they have firewalls installed over their backend which I guess may be the reason you can't access the Google.com or Facebook. Okay try installing some free proxy softwares and then try accessing the Google.com or Facebook.com if by that time it start working fine then I guess I was correct it's the problem with the ISP end not your end.

I'm not being blocked as I can access those sites just fine from my phone. The problem only occurs when I tether and appears to be DNS related.

Is there a way to determine whether upgrading to a newer version of Android OS will slow down my device?
Is there some way to test whether my device is ready for version xyz of Android (i.e., how much it will slow down the device?
Or some sort of table of how much slower each version of Android has become.

Installing the new version would be a way to test. Alternatively, you have to rely on hearing from other people who've done that, but to get that kind of information, you need to tell us what phone you have and what version you're thinking of upgrading to.

In my limited experience, I've not been able to uninstall OS upgrades to my android phone.

Well, no there is no any test which could help you in determining, and yes one more thing OS upgrades make your device faster rather than slower. So I am sorry but I don't think that there is any use  of asking such question. Flashing ROM other than the stock ROM can results in decreasing speed or other similar problems but I don't think that downloading and installing the OS upgrades received directly from the vendor will slow your device down, because before feeding those ROM over the air they perform a number of test to give your flawless experience.

There is no "test" to my knowledge like there was for windows. However, to ensure the best results from an upgrade I recommend factory resetting your phone after you back up your information. This will ensure no third party app incompatibilities with the updated software.

Need to enable ICMP Ping response from phone
I'm trying to enable ICMP ping response from my Android 4.2.2 Phone (Galaxy S4). I am only considering ping over LAN via Wi-Fi, not the cellular network. WLAN Network connectivity is not the problem: I can connect to an FTP server running on the phone from another machine on the LAN. Pinging the phone from the same host of the FTP client results in timeouts. The phone is not asleep because the FTP session can be active, but ping still times out.
I can also ping an Android 4.4 tablet just fine, so it is not something specific with Android.
In the phone, I examined /system/etc/sysctl.conf and found the line:
sysctl -w net.ipv4.icmp_echo_ignore_all=1;

which I commented out as (editing with ES File Explorer Root Explorer, FS set to RW)
#sysctl -w net.ipv4.icmp_echo_ignore_all=1;

After rebooting the phone, there is still no ping response. What other settings could inhibit ICMP ping response?
Edit: I also tried the form
sysctl -w net.ipv4.icmp_echo_ignore_all=0;

That did not make a difference.
I can ping any other host on the LAN, including the router, from the phone using the Net Ping app.
I also discovered that I can ping the phone at its IPv6 link-local address (fe80::xxxx)
It will respond to pings while the phone is awake, but as soon as the screen goes dark, ping responses stop. But I do not get any IPv4 ping response under any circumstances, so some setting is blocking it. I do not have any add-on firewall like DroidWall running.

Since this isn't usual Android behaviour, it might help to tell us what phone you have and what kind of network connection you're using.

Samsung Galaxy S4 Rooted, Wi-Fi network.

Can you ping the other machine from the phone? Your Wi-Fi router could be blocking the echo requests.

Yes, I have an app on the phone called Net Ping. I can ping any other host on the LAN, including the router.

I tried changing the sysctl.conf line to "sysctl -w net.ipv4.icmp_echo_ignore_all=0;", but still no ping responses

You should add that information to your question by [edit]ing it. The site doesn't show all comments, so it's easy for information to get lost there.

The simplest (and, of course, tricky) way is to use nping. For example:

nping -c <ping_count> --tcp -p <your_ftp_port_number> <ip_address_of_your_phone_hosting_ftp_service>

Achieve same goal without modification of Android.

I know this question is quite old now, but I came across this looking to for an answer and managed to work it out myself.
What I did was download a root file explorer (I used Root Browser from JRummy Apps) and navigate to /proc/sys/net/ipv4 edit icmp_echo_ignore_all so that it is a 1-line, 1-character file that simply says 0 (when I opened the file, it was set to 1)
No reboot, ICMP requests started working upon saving.
Hope that helps someone else!

something permanetly reset my email accounts from installed mail applications (Samsung Note II stock and Gmail app)
I've met with a very annoying and strange issue regarding email applications on my Samsung Galaxy Note II. My search in Google across multiple Android forums has has not given any result. I used for about a year on this device Samsung's stock email application to work with my mail accounts at some local mail servers and Gmail server. Also I used Gmail stock email app to work with my several Gmail accounts (some of them are the same as in Samsung's stock email app and some are different).
One nice day several weeks ago I've suddenly disclosed, that all my mail accounts in the both apps are totally removed, that is all accounts settings and data (incoming messages loaded in the local cache, my drafts etc). When I called any of these two app, it starts as the very first time, that is offers me to configure any account before I can start using the app.
Futhermore, the default Google account in the general stock settining ssof the account has been removed too.
I have restored all accounts in the both apps and the default Google account in the device`s general settings. But several days later I've suddenly found out, that the both apps had reset and were empty again. Well, I've configured them once more... and now they are empty again.
I suppose, that this issue is very probably conncted to the fact, that I use the same Google account as default account on two different Android devices, that is Samsung Galaxy Note II and LG G-2. Well, I have read here at the forum many different topics with the same questions, whether it is OK to use the same Google account as a default one on multiple devices, and the answer was always "Yes, without any problems". But seems, that the matter is not so simple. Anyway I can not imagine any other reason for such strange behaviour. Furthermore I suspect, that the problem occurred the first time after I've bought and configured my second device LG G2. I'm not 100% sure, but it seems to be so.
What seems to be essential, all data and setting of these email accounts on my LG device is not affected any way.
Are there any ideas how could I detect and fix this issue? It is impossible use my Note II this way.
Many thanks in advance!

Since it's not caused by using the same account on two devices, you'll have to give us some more clues. Did you install any new apps around the time it started? Have you been clearing any app's data from the settings?

Yes, I have installed some new apps in the meanwile. But I very doubt, whether some of them can be connected to to this issue. Anyway none of these new apps deals directly or indirectly with email, even less should they handle my device's general system settings.

Well, some days ago I have uninstalled antivirus software Norton Antivirus (or something lalike, I don't rememeber the exact name of the app). Could it take with it my email accounts data from the two main email applications? I'm not sure. The problem is, that I have not noticed the exact moment, when the data has gone.

Well, like the other forum I would also say there's just no problem with using two or more devices over a single gmail account. I remembered you said that "local mail servers and Gmail server"data gets deleted. I think that might happen because of something else i.e not related only with the gmail account. Do one thing try factory resetting your device and then try putting the gmail account back in place and see if that again disappears or not!
PS: Make sure you backup your data before moving forward with the factory resetting.

Thank you for your advice, but during many months I have tried so hard to configure my device and installed applications accoring to my needs... So I'd pefer not to lose all my custom settings unless we make a conclusion for sure, that there is no any sofer solution.

Well, I am sorry but I can't think of any softer solution for fixing this issue up !

what will happen if i leave my smartphone(samsung gt8150) with an already ruined battery a whole day plugged into the computer?
I use my smartphone for tethering and i have a ruined battery which will keep the device on for not more than 1 minute but can be plugged in to the computer or charger.Is it ok to leave the device for a  whole night or a whole day for tethering? Will it damage the smartphone?
I edit to specify that im using usb wifi tethering

Well, its okay to leave the device plugged over to the charger with a ruined battery. Let me tell you a little secrete I am doing the same thing thing from last month, What I need was a router so, I got the idea the same way like you are talking about I plugged my s2 with the charger with tethering switched on and viola I no need of spending few extra bucks for router. I use it to tether the internet over my notebook and s5. Still no sign of any unusual problem, I usually switch the charger off when I am at my workplace. So, I would say instead of keeping it switch on continuously switch it off when not in use you will never encounter any problem.

Definitely a yes based on the conditions of the battery.
If the battery is not more then  1 year old(frequently charging or extreme usage of the device for the most of the time)
If the battery has any dent's etc.
If the battery is showing early signs of disfiguring.(Battery starts to swell due to overcharging which leads to overheating and thereby it will not fit in your device leaving your device useless for any purpose you desire which require using the battery i.e. dead phone without battery)
If the your battery satisfies anyone condition from the above then you have to replace the battery with a new one.

thanks very much for reply, i understand but will using long time tethering with broken battery ruin ?

its surely deteriorated becouse is bigger than usual and doesnt work ok at all. i have another i wanted to use it only for downloads too big for the smartphone

yes Replace now don't wait further for any untoward incident may happen

I've got a Samsung Galaxy Grand Neo (Jelly Bean). It has a 5 mp camera but I'm not satisfied with the picture quality. Will it help if I use another app like Camera Zoom FX or anything? If yes, then which app should I use?

Some camera apps improve the photos taken, but it's usually on a case-to-case basis. Some phones have limited / low-quality hardware and won't benefit from 3rd-party apps. Others have high-quality hardware, but poor camera software.
It's difficult to recommend a specific app. I have a Samsung Galaxy S4 and have installed the following: Camera Zoom FX, ProCapture, Snap Camera, official Google Camera. However, I don't get very good photos, probably because I think the camera is defective. My phone has been dropped several times already.
But your mileage might vary. Try the different apps, and see what works for you. There are trial versions.

How to remove all icons from the Android home screen at once?
I am cleaning some old Samsung Galaxy S2 with Android 2.3.4. Some application added shortcuts on the home screen:
Uncleaned:

Cleaned:

Is there any way to remove all icons from the Android home screen at once?
I know that I can remove icons one by one by tap, hold and drag the icon to delete:

but it is a bit tedious (I have several screens to clean) and I want to remove all icons at once.
Ideally, I don't want to clean all the screens but only one.

Your situation is due to the Auto add widget due to which when ever you install an app it wall automatically add an widget on your home screen thereby increasing the home screen count also.
I will first solve your home screen problem and below I will also give a screen shot where the problem can be solved for the future also.
The below steps is easy to follow and requires some patience to clean the clutter.
There are two ways to clean a home screen in any Android device.
Option 1 will help you clean your home screen through the apps available in the play store.
Option 1
Download any launcher which suites your requirement like GO Launcher  from the play store and clean the home screen as per your requirements from the settings.
If you don't want any hassle of any more apps then go for Option 2
Option 2
Step1-Do a normal zoom out in home screen (or) From home screen page, press the Option button, then click Edit  and it will display all the home screens and their content.
Step2-Either click on remove and remove all the home screens except for 1 or you will be getting a small minus (-) symbol right side corner of the home screen. Click on the minus and remove it.
Step3-If you have followed the above 2 steps correctly then you will be getting a single home screen from which you can easily delete the widgets(it solved your problem of deleting around 84 widgets and brings the count to only 12 with just a single home screen).
Step4-Under the Play store settings uncheck the auto add widget in order to ensure you do not face the problem in the future.

This solves the underlying problem as well as the current issue.  Great answer.

thanks but hopes this is helpful for the owner who posted it as well as for the future users

Well, I seriously don't know if that works with Android 2.3.4 or not but the method I am going to stat works with Jelly bean 4.2.2. Instead of removing the application over the home screen try directly deleting the whole home screen. Instead of dragging the icon try deleting the whole home screen. See if that works out for your or not ??

Can I run apps with similar function?
Recently I have installed Juice Defender and Greenify.
Unknowingly I ran both of them. The result is pretty great (battery almost stopped discharging). Battery levels stood constant for hours when my screen is off.
Is it good to run both of these apps together?

It's fine.  If they work simultaneously without your phone bursting into flames, just let 'em run!

Typically it is advised not to run two apps that have overlapping management areas.
If you aren't seeing excessive activity/drain due to the two apps stepping on each others toes then it is not bad. From your take so far, it does in fact seem good in this case.
You wouldn't, for example, want two anti virus software running side by side in the same environment. That would usually be bad.

ADB restore isn't working
I think there are a lot of this type of questions but I have a new (for me and can't find it anywhere) problem with the adb restore command.
I created an adb backup -apk -shared -all and it looked like it worked and I think it did because the size is 6 GB. Well I made this from Android L Preview because I wanted to downgrade because of the bugs (I hope they fix them) and when I try to restore it on Android KitKat 4.4.4 it is not working, the adb shell logcat -s BackupManagerServicereturned this when I tried to make a full restore:
I/BackupManagerService(  758): Beginning full restore...
D/BackupManagerService(  758): Starting restore confirmation UI, token=1224340204
D/BackupManagerService(  758): Waiting for full restore completion...
D/BackupManagerService(  758): acknowledgeFullBackupOrRestore : token=1224340204 allow=true
D/BackupManagerService(  758): Sending conf message with verb 10
I/BackupManagerService(  758): --- Performing full-dataset restore ---
I/BackupManagerService(  758): Initiating bind of OBB service on com.android.server.BackupManagerService$FullBackupObbConnection@437913f8
I/BackupManagerService(  758): OBB service connection com.android.internal.backup.IObbBackupService$Stub$Proxy@43ad7c48 connected on com.android.server.BackupManagerService$FullBackupObbConnection@437913f8
W/BackupManagerService(  758): Wrong header version: 3
W/BackupManagerService(  758): Invalid restore data; aborting.
I/BackupManagerService(  758): Full restore processing complete.
D/BackupManagerService(  758): Full restore pass complete.
Is there a fix for this? Or another way to restore this information? The backup is encrypted but there is not an error of a wrong password and I am pretty sure it's the correct password.
Thank you for your time and I hope you can help me solve this.

You can't restore a backup made from a higher Android version onto a lower Android version. This can be seen from the line W/BackupManagerService(  758): Wrong header version: 3. ADB backups should always be restored onto the same version (or higher, not sure about this).

I thought it could be that but I am a little new on this so I needed to check that with some other people, thanks for the answer but tell me something, is there a way to make a Backup of a newer Android version and restore it on an older one? And to understand more, what's the header version? How could I understand the number next to it? Thanks!
