Will deleted apps be restored when I reset factory data?
I need to reset my phone to get it back to what it was like when I first bought it. If I reset it to factory settings, will the apps I've deleted be restored as well?
If not how do I find and restore those apps?

These deleted apps: did you delete them from the system partition or the userdata partition?

Inbuilt apps that you deleted/disabled will be restored. Any apps that you installed from Google Play and weren't pre-installed on your phone wont't be restored.
You will have to redownload those apps again which you want to use again. Also give this a read and the linked question inside.

Deleted system apps will not return on factory reset, only when the ROM is reflashed.

how to remove google + auto back up pictures
Is there a way I can remove the auto back up folder from my S4. Its taking up a lot of space for the backup folder of just pictures and I dont want it there.

go to your google+ app, choose settings and the very first thing you get is General Settings - Auto Backup
you can turn that completely off, or you can specify and change the settings of the back up

What does the "Aggressive Wi-Fi to Cellular handover" option in Developer Settings do?
In Android Lollipop 5.0, I noticed that "Developer Options" features a checkbox for "Aggressive Wi-Fi to Cellular handover" that is unchecked by default. Does anybody know what this setting does and why it's disabled by default and hidden under developer options?

Judging by the name of the option it seems that checking this option makes the phone be more happy to use cellular data when WiFi signal is bad

The code for shouldSwitchNetwork() best explains what it does.  It just artificially reduces the WiFi RSSI (received signal strength indication) to encourage the WiFi state machine to decide to switch the connection from WiFi to cellular network.  Around line 3559 of WifiStateMachine.java (line 4262 for Android 6.0.1_r10):
int rssi = mWifiInfo.getRssi() - 6 * mAggressiveHandover
        + (homeNetworkBoost ? WifiConfiguration.HOME_NETWORK_RSSI_BOOST : 0);

The variable mAggressiveHandover is an int that is set to 0 or 1 by the Developer Settings:
private void writeWifiAggressiveHandoverOptions() {
    mWifiManager.enableAggressiveHandover(mWifiAggressiveHandover.isChecked() ? 1 : 0);
}

The rssi variable goes on to influence how the connection is classified: isBadRSSI, isLowRSSI, or isHighRSSI.
As to why it's hidden under the developer options, I'd say that is because it seems a little hackish, with a seemingly arbitrary scalar (6) that some dev came up with to nudge the behavior in the desired direction.  Google is probably uncertain about the consequences of this setting and the optimal way to adjust rssi.  If I'm wrong and this is somehow meaningful, I'm happy to admit it and explain here why.
Turning this setting off does NOT turn off cellular handover altogether.  The WiFi connection still gets a score and is disabled if the score is too low.  But hey, the initial score is set arbitrarily too.

Wifi to Cellular Handover is a feature in phones that automatically switches to cellular data when you do not have a strong WiFi connection.  You would want to enable this for a few reasons:

It will save battery - If your phone doesn't switch to cellular data when it can't connect to a Wifi connection, your phone will continue to search for WiFi, thus using battery.
You won't have to turn off WiFi when you leave your house or when you don't have a connection in order to use data.

So does having "Aggressive Wi-Fi to Cellular handover" turned off turn off the feature completely? or does it simply alter the behavior to have a higher cutoff for when to switch from wifi to cellular?

No it does NOT turn off the feature completely, nor will it turn it ON by enabling it, it can ONLY be turned ON/OFF in settings → Wi-Fi → Wi-Fi Advanced menu (The three dot icon in the upper right hand corner) and then checking the box next to "Smart switch" (Verizon Samsung Galaxy Note 4 Android 5.1.1), otherwise the only thing that you're honestly doing via the developers menu is simply forcing this same exact option to work if/when your phone is experiencing any type of network "hiccup", and it in a way forgets to change the network type. I suppose you could think of it as a blunt or abrupt reminder to the system to change its internet connection from Wi-Fi to cellular data, and/or vice-versa.

Thanks for trying to help the OP, but this was asked 1 year ago, and your answer is hard to follow along for readers. Can you edit your post to properly use bullet points and/or code markings?

Phone app: what does the blue forbidden sign (with optional blue "A" in front) mean in the call log?
I have the following question concerning the Samsung Galaxy SIII:
When one taps Phone -> Logs it is possible to see the following icons:

Incoming calls which were answered and received text messages
(icon displays a green arrow pointing to the left)
(clicking entry displays date and time call was received
or text message was received and call duration for calls)
Incoming calls which were not answered
(icon displays a white arrow bouncing to the left off a red phone receiver)
(clicking entry displays date and time call was received
and displays the text "Missed")
Outgoing calls
(icon displays an orange arrow pointing to the right)
(android phone app does not differentiate outgoing calls which were answered
from outgoing calls which were not answered, but clicking on the entry displays
call duration for calls which were answered or the text "Canceled" for calls
which were not answered)

However, I am not sure what the following mean in the Phone application:

icon displays blue circle with diagonal line through it
(clicking on this entry displays a date and time and the text "Canceled")
icon displays blue circle with diagonal line through it
with blue uppercase "A" in front of it
(clicking on this entry displays a date and time and the text "Canceled")

What is the difference between these two icons?
Thanks.
The five different possible icons I mentioned appear in the following screenshot (contact names and phone numbers scribbled-out, click to enlarge):

The icon that displays a blue circle with diagonal line through it in the Phone app's Log tab appears when the user receives a call and manually rejects it with a swipe when the phone rings. As soon as the user swipes to reject the call, the caller will hear the tone of the phone call change from a ringing signal to a busy signal.
The icon that displays a blue circle with diagonal line through it and a blue "A" in front of it in the Phone app's Log tab appears when the user receives a call but the caller has been added to the reject list from the Contacts app. In this case the caller will never hear a ringing signal and will hear a busy signal as soon as the call is made, and the receiving party will not hear the phone ringing since the contact was added to the reject list of course. The blue A in front of the blue circle with a diagonal line through it is most likely understood to be the first letter of the word autorejected.

Regards.

Just now 'The blue A in front of the blue circle with a diagonal line through it' happened to me.  I read your answers and assumed the person I was in contact with added me to autoreject list.  Please do not come to conclusions that technology always works as we predict it to work.  The person was in a government building which blocked all his calls.  He had to contact his boss and realized his phone was not working. I assumed he put me on autoreject list, when in fact, the building he was in must have some controlled signalling system setup.

How do I get to the "Home" in Play Store?
I feel really dumb for needing to ask this.  When I'm using the Play Store app, how do I get back to the main screen?  Currently I hit "Back" multiple times to get there, but if I have done a lot of browsing, the navigation history is very long, so I have to hit "Back" many times.
Is there a quick way to get back to the main Play Store screen without using the Back button?

Whenever you navigate the Play Store using the app, each app page has a left-arrow just below the status/notification bar. I have just tested this to 20 levels deep, and the arrow brings you to one of 2 places:

Play Store home directly, or,
that account's navigation menu, including Store Home as the first option.

To get to the front page of Play Store, with a lot of history, it may be cumbersome and time-consuming to press the back key or the up key (the left arrow in the top-left). Below is an easier method. Note that this is only possible on devices after Gingerbread (Android 3.0+)

Add Play Store to your home screen from your app drawer. Note: This is optional, but it will save you time in the future.
After browsing for a while, open your recents by holding the Home button, or Recents button if you have one.
Close Play Store by swiping the thumbnail either to the left or to the right, or by clearing all recents, if you don't mind closing all the other apps that are open. Note: Functionality to clear all recents may vary from device to device.
Go to your home screen by pressing the Home button.
When you open Play Store again from your home screen, it will be back at the front page.

How to remove Polaris Office on HTC phones?
I have Polaris Office installed on my HTC Sense 6, but I cannot delete or find it on my installed apps, Play Store, and even Device Administrators. Though, I can run the app and use it.
How am I going to delete it?

what app is it? Sometimes they're named strangely in the app list.

OP: Please clarify: What application? From where are you able to open it?

It's Polaris office. Not listed on playstore, cannot discover it VIA file managers, not a device admin and uninstall option is grayed out.

let me suggest something. let someone transfer the latest updated version of the app as apk file(via any app sharer) then install it on your phone that will upgrade your app and possibly fix the problem

Could you clarify your phone model? AFAIK, Sense 6 is not the phone model, but the version of HTC UI framework.

@Andrew yes its the framework.

@Devrim if your rooted it would be simple, you can use a system app remover such as this.

From HTC Rezound (Verizon Wireless)'s FAQ (I know it's a different device, but it's same for most HTC phones),

What is Polaris Office?
Polaris Office comes pre-loaded on the phone and can be used to open and view office documents (Word, Excel, PowerPoint) received in email as attachments or stored on the SD Card. [...]

(Emphasis mine)
In other words, it's a bloatware. You need to have root access to uninstall bloatware.
If not, you can still disable it. Since it's not installed as a normal application, it won't be listed as your installed apps. Instead, you have to select "All" tab to list all apps, including bloatware. Then you can find and disable the app from there.
Alternatively, long-press the app from the app drawer (not home screen). There should be "App Info" on the top of the screen. Drag to there and release, and it should open the app info where you can disable it.

Thanks @andew I realised it is actually a bloatware after checking another device yesterday.

If you can run the app and use it this means there is a widget where you can use to enter.
Long press that widget(app icon) from home screen, since long pressing from app drawer just adds it to home screen, choose app info, this will redirect you to the app in the application manager where you will have options to uninstall or clear data...

Long pressing on sense ads a shortcut on the homepage.

long pressing from almost every android adds on homepage... i ment from the homepage

Not every app has a widget associated with it. Polaris doesn't have a widget. A shortcut isn't the same thing.

How can I force a media rescan on Lollipop?
I would like to force a rescan so that the MTP file listing is correct when I use Android File Transfer on my Mac.
I've tried a half dozen apps but none of them seem to work on Android 5.0.
I have rooted my device.

Unmount and mount your SD card

There is no SD card on a Nexus 5.

You can try heading over to the Settings>Apps>All, Look out for Gallery app, tap over it and Clear Data and the Cache Stored.

Once I've done this how do I refresh the cache? If I follow these instructions and then connect to a computer I can't access any files.

Hey @Venko did you followed the method I have guided you ?? I am not getting the cache refresh thing because once you clear the cache and the data it automatically refresh the cache ! So, there's not need to do that manually and about your PC can't access any files you need to make sure that all the device drivers are installed and if that still doesn't shows thing then you can also try changing the connecting like to MTP or Portable camera.

Lock screen while playing YouTube video
I have Samsung Galaxy S5. Is there a way to lock the screen but keep YouTube videos playing?
For example, a particular browser app or add-on that would allow for the audio to continue playing while the screen is off.

Related: How to play a YouTube clip in background/minimised?

You can with an All Access Music pass for YouTube/Google Play music.

tried youtube vanced already? see if it helps

Download MX Player
Play YouTube video using MX Player.
Press Menu button (or the 3 dot icon), and then select Play
Make sure "Background Play" is checked
Now, you can press Home Button and listen in lock screen.
There is also a shortcut for enabling Background Play, which is tapping and holding the Play button, instead of just tapping it to play a video

Update #1
Only For Rooted: You can install Xposed Modules Installer and use Repository called Youtube Background Play
Update #2
As suggested by @Tanishq Banyal in comment YouTube Vanced is pretty good alternative if you are open to installing 3rd party application/mod.
It works for both rooted and non-rooted Android.
Using Youtube Vanced Manager is pretty straightforward, in case your mobile is not rooted you are required to install Micro G along with main application.
Along with background play you can also block ads in Vanced.

Just try YouTube Vanced, basically YouTube Premium for free, it was made by ex-google employees I think.

The newest workaround doesn't require any new apps to be installed.
Follow these directions:

Open Chrome browser.
Navigate to the YouTube video you want to watch.
Click the Chrome menu and select "Request Desktop Site".
Play the video.
Click the home button. The video will pause.
Pull down the notification menu and play the video from there.
You can now lock the screen.

This works without any fault as long as you keep the video playing. I played single videos for up to two hours without an issue. I noticed the following issues, which affect when I'll use this workaround:

If you pause the video from the notification, you will be able to play it again, but not if you leave it paused for too long. I didn't time it, but the notification control disappears in less than 30 minutes. You'd have to then open Chrome again and replay the video. The same is true if you pause the video with a blue tooth control.
If the video buffers because of a loss of connection, it will start again automatically, but only if it doesn't buffer for too long. Again, I did not time it, but I had issues after only a few minutes of lost connection, but that could have been related to item 3 below.
Switching from wifi to data or data to wifi connection often created a buffer issue. It always seems to auto play after a few seconds when going from wifi to data, but not when going from data to wifi. Data to wifi would take longer and sometimes not autoplay at all. I think this is because when the phone establishes the wifi connection, there's a delay in the ping back that lets apps know that connection has been reestablished. I noticed multiple times that autoplay would work within seconds of unlocking the screen.
After a video's end, autoplay doesn't always work. I found no pattern for when it would work.
On long videos that you might listen to parts of over several days, in addition to having to start the video from Chrome again between every break longer than an hour, you may also have to scrub to the time where you left off. Multiple times, it seemed Chrome would decide to reload the tab, making the video reload to the beginning. It seems to be more reliable if I leave Chrome open (but in the background), but it still occasionally reloads the tab. If you're fast enough, you can read your time as you open the tab before it reloads, making this only a simple nuisance.

I've been listening to a lecture series in a playlist this last week and these are the issues I've noticed. In light of the trouble I've had, I think I'll just download the MP3 from now on, but I'll use this hack method if there's just a single video that piques my interest in the moment. In other words, I recommend that if you have the time and desire to listen to a playlist, it's just easier to go through the steps to download the MP3.

^^ this. The "chosen" answer says to download a 3rd party app which seems to no longer stream you tube videos.

Clock off by 4 min even if "use network value" is on (probably due to an app)
Few days ago i noticed that the clock on my phone was 4 min earlier than "real" time. I thus moved to "parameters > date & time" to check that automatic was "on" and indeed it was "on". I then unchecked/rechecked the box and every get back to "real" time ... but only for a few seconds ...  indeed just a few seconds later the clock suddenly shifted 4 min earlier!
I tried many things before finally discovering that if I turn off "data" connection, the clock remains at correct "real" time. So it is probably an application that for unknown reason is synchronizing to some server and then modifies the clock.
I have a HTC desire - Android 2.2.2 and I have installed no particular application that can make me suspicious to create such time shift (nor i tried to root my phone to any custom ROM).
Any idea for which application could do this or anyone else having same issue ?

Try disabling network time and set the clock manually. Network time relies on your mobile operator setting their clocks correctly, while it is usually a good bet, some misconfiguration on their side could mean that their clock is returning incorrect time. Another possibility is an issue in the database of time offsets in the device (this controls corrections for leap second, etc).
Try checking your time with http://time.is/.

Thanks for your reply. The network time provided by my operator on gsm/cdma signal is in line with many other clocks (including the link you provided). It is only when I activate "data connection" that for some reason it shifts 4min earlier. I will try to spy wifi to find which connections are made. Maybe some app/service is connecting to a NTP server having incorrect timestamp.

NB: The application installed on my phone are so few and so basic (gmail/play/street/youtube) that it's anyhow hard to suspect them  ... maybe a service ... :/

Some say they have an NTP server host-name entry in their GPS config, the file seems generally to be /etc/gps.conf. You may need to be rooted to access this file, while it seems they are few chances that GPS settings offer to set-up that parameter on Froyo.
TIP : You could verify that theory if that problem occurs only when both GPS and DATA (or WIFI capable of routing NTP) are activated.

Unable to Download Kindle Books/Dropbox files
I have a Samsung Note II running Android 4.4.2. I recently rooted it, and after rooting I am unable to download content for certain apps, for example Kindle books or dropbox files.
Some other apps seem to work fine.
Thinking this is a file permissions issue, I downloaded an app called "Fix Me Storage" which seems to run successfully, but I'm still running into this issue. I also tried the NextApp SDFix tool and it said no action was required.
I have enough storage on the device but am still unable to do this.
Sample Scenarios:

Kindle: When I try to download a book on a kindle, I get this error:

"Unable to Download": A network connection is required to download
  your Kindle title. Please connect to a network and try again.

This happens on Wifi and 4G, and even after uninstalling, rebooting and reinstalling the app.

Dropbox: When I try to open a pdf file with a viewer on the device (Drive PDF Viewer, or ezPDF), I get this error:

Storage full or unavailable.

However, I have ample room, both on the phone and the plugged in SD Card.

It might help if you could include some more details: Where are you trying to download to? With Kitkat, first thing coming to my mind are the SD card restrictions it introduced (and which can be fixed using e.g. SDFix).

Thanks. I'll try SDFix. I'm just trying to download books (on the Kindle), or open PDF Files.

Both Sims are not detected after update Lenovo A390 with the latest ROW firmware
I have format my Lenovo A390 and update to latest ROW firmware version A390_ROW_S316_130730.
Everything work fine but sim cards not detected. At down of the lock screen shows Invalid IMEI. In the status bar sim also not showing.

Model number     :- Lenovo A390_Row
Android version  :- 4.0.4
Baseband version :- A390_MB_PCB_V1.0
Build number     :- A390_ROW_S316_130730

IMEI are Unknown
Wifi also work fine. What should I do now. Please help

Head over to the dialer and type *#06# over it and see if it shows the IMEI number, if it shows the IMEI number then things are okay but if there's nothing showing over their means the problem is with the IMEI and the device needs to feed IMEI onto !

IMEI doesn't show with  *#06#. Both are Invalid. :/

Well, I have Google thinks out, and have spotted a post over GSM Hosting you can have a look over the post ! And see if that helps you out with the problem you are experiencing !

I have solved the problem myself. Reason of the problem was Invalid IMEI number. What I did is set the valied IMEI for Sim.
Steps to Change IMEI Number of Your Android

Write the following in your dialler – *#7465625# or *#*#3646633#*#*.
(*#*#3646633#*#* this work for me)
Click to Call pad or connectivity options. Find out CDS information
and tap on it. Check out for Radio information. If
you have dual SIM, there will be two options for you, select the one which you want to go with.
Now to change IMEI number follow
AT +EGMR=1,7,”IMEI_1”

Replace IMEI_1 with your IMIE. For example : AT+EGMR=1,7,”8600XXXXXXXXXXXX"

And click to send.

Changing IMEI number is illegal but it may help you to get your phone back. Make sure to use  "YOUR" phone IMIE number (15 digit code ) written in the backside of the phone (mostly Under the battery)
EDIT
For Sim 2 need this insert “AT +EGMR=1,10,"IMEI_2”

Only one sim working. Other sim shows Invalid IMEI

For Phone 2 need this insert “AT +EGMR=1,10,"IMEI_2”

How do I install a custom ROM on a Prestigio PMT3677
I want to install a custom ROM like Cyanogenmod or similar on my 7" Prestigio tablet.
There doesn't seem to be any content on the net to explain what ROMS are compatible with this specific model and the steps to be followed to install a custom ROM on the device.
It's currently running Jellybean 4.2.2 but the tablet has extremely slow response times for most apps (and I have very few apps installed). Installing a custom ROM might make it a little faster and give it a nicer look.
I've already rooted the device using the same method as you would use to root the Prestigio PMP3670.
I don't want to just take a chance by installing just any ROM without following the right procedures for fear of bricking the tablet.

Custom roms must be ported separately for all device models. Installing a wrong ROM on a device even marginally different from the one it's intended for has the potential to brick the device permanently. If you cannot find a ROM made specifically for your device model, you are out of luck.

I figured as much, guess I may have to wait for one to be made or perhaps try and build one with JDK...

Pointer: Where can I find stock or custom ROMs for my Android device?

OTG Is it possible to connect two devices
I would like to be able to copy files from SD card (through card reader) to USB flash drive. All is connected through OTG USB Hub, but all the apps I found mount only one OTG device at a time. Is there any way to connect two at once?

YES - it is possible. It seems thought your phone/tablet has to be rooted. I've tried all the apps I found without root and could only connect one device at a time. Today I rooted my tablet and got Stick Mount app. Now everything works great - I can  copy files between SD Card and USB Drive, which is what I wanted.
Here is the link to the app: https://play.google.com/store/apps/details?id=eu.chainfire.stickmount

No it's not possible ! I have tried doing that myself and a error pops up ! So, without doing any extra terrestrial tricks its not possible !

According to comments you can with that app (root): https://play.google.com/store/apps/details?id=eu.chainfire.stickmount&hl=pl

Agreed. I've seen this noted on different apps in my list: Mount Manager. Seems there are some extra-terrestrial developers around :)

Whoo... that sure do looks extra-terrestrial to me ! Any I would say Android had space for this nuisance too but it can be done by removing the barriers! Staying inside the boundaries isn't going to work things out ! :D

I managed to do it with root - see my answer.

@MichalDymel well, that's great! I think I need to start digging up the things a little more ! ;)

Dual Sim: Surfing while receiving an incoming call
I am planning to buy a dual sim mobile phone. One sim for cheap surfing and one sim for for calling. But i am unsure about some techniques of the technology.
If am surfing with sim2. Can the sim1 card receive incoming calls? Or is the sim1 blocked, as long as i am surfing?
best regards
zesman

Using a dual sim smartphone is the same as a normal one except for:
-You can't use a sim while the other one is calling (it goes to airplane mode)
-You can use one mobile data sim at time, but they'll both receive incoming calls
So if I understood correctly your question, yes, you can

No status shown below display name
When I look at the list of my Viber contacts, I see three different statuses which are online, offline and last seen at. However, there's one particular contact which doesn't have any of it, I mean nothing is written under the name on his contact profile on my phone. What does it mean?
He can't have uninstalled Viber cause his account looks recently refreshed. He has updated his photo along with his Line App. So what does this really mean?

possible duplicate of What do Online and Offline mean in Viber?

@bmdixon I don't think it's a dupe of that question. From the original title, this question seems to ask the meaning of those status, but the question body clarified the OP's intent. I've suggested an edit to clarify it.

Viber has a privacy settings where you can hide that status
you can find that by clicking the "more" button... that is the three stacked horizontal lines, then choose settings then privacy. you get something called "Share 'Online' Status" you can untick that if you want to hide it. Note that you can change it once every 24 hours

I know it's not asked by OP, but it would be better if you could add the step to do that for the sake of completeness

no problem, i added it

How untangle two Whatsapp accounts created with the same numer?
First, I installed Whatsapp on my Alcatel phone, with my whatsapp account ("son").
For my old mother, I bought her a big screen, cheap second hand Samsung Galaxy, (poor eyesight). That Samsung is blocked by the phone company (long history, don't ask); it can't make/receive calls.
I installed Whatsapp (via Wi-Fi) on her phone using my own phone number (stupid mistake) to get the audio check code. She got her own account ("mother"). It works almost fine, but I ("son") can't add new contacts because invite responses goes to "mother" account.
I changed phone number in "mother" whatsapp to her real working Nokia basic phone, but still doesn't work.
Short of deleting "son" and "mother" Whatsapp accounts, or buying a new SIM card for me, can you think another solution? I live 4 hours away from "mother". I don't want to lose 2 years of messages and contacts.

Further questions: What happens to the other people involved (contacts)? Do they need to do anything? If I delete, then recreate my account, Am I still the same person? Can I reuse my handle/Id/name?

You can save a backup of all messages you have, then going through settings - account you can either: delete the account then activate it again another time using the correct number for each phone. or use "change my number" and reactivate the account with the wrong number to the correct one

Causes and solutions "UIDs on system are inconsistent... I'm feeling lucky"?
HTC One Mini 2/Android 4.4.2/HTC Sense 6.0/Not rooted/4 weeks old
A couple of days ago i encountered this message on my phone:
UIDs on system are inconsistent
You need to wipe your data partition or your device will be unstable
[I'm feeling lucky]  (button)
...and then ensued a long day of tech support & research which i wanted to share here.  Web searching did not solve my problem directly, and while i can add a couple of insights that i didn't find elsewhere, i don't really have an answer.  Many of the information i found was from people who had rooted their phones, and therefore not directly relevant to me - i am approaching this from an un-rooted phone
.
Symptoms/history
Phone crashed while browsing HTC's blinkfeed, and restarted
It limped along for a few minutes and restarted again
Phone then gets stuck at white HTC/android screen and remains there (left for several hours) - ie cannot power off, screen remains on
Later, i discovered that you can proceed beyond this screen by ejecting the sim card - this then shows the lock screen (active background, time, date etc) but on top of this is the message UIDs on system are inconsistent... and one button which says "I'm feeling lucky".  Whether you can press the button seemed to be allowed if you changed the position of the sim card - (ie if out, push it in, if in, eject it).
After dismissing the strange message, i am left with a black screen with notification bar at the top, and navigation bar at the bottom.  No apps; no widgets.  The notification bar was working, in that i could swipe down, enter settings etc.  Further, if i received a text, i could then access my messages via the notification bar, but could not reply to a text because the keyboard did not load.  Having used an app like messages or settings, i could switch between them with the bottom right navigation button as usual.  I found that i could receive phone calls, and once done so, i could dial others by switching back to the phone app.  This about sums up the functionality of the phone.
The other comment was that the phone could not be switched off.  Holding down the power button and selecting power off simply resulted in a restart of the phone.
After further investigation with HTC technical support i found i could restart the phone in safe mode, but exactly the same process happens (ie restart, ejecting and re-inserting the sim card and agreeing to the "I'm feeling lucky" button to get back to the main lock screen).
HTC technical support wanted me to do a hard reset: this can be done in one of two ways, by software (an option under settings>backup & reset>Reset phone) or by hardware (holding down volume-down and power during start up.  The software method had no effect on the described behavior.  We tried this several times.  The hardware method was unsuccessful, the phone simply restarted in safe mode.
HTC technical support finally admitted defeat, unable to think of something else suggested sending it in for repair.  Vodafone tech support also offered to send a pack for returning the phone for repair.
All comments/further info from the community will certainly be interesting, but please also see below, as i did manage to avoid sending back the phone for repair as I did eventually succeed in the hard reset.

A Solution
On reflection, my thoughts were 1) this seems like a software problem, possibly malware of unknown origin and 2) it seems to be interrupting the power-cycling of the phone.
Therefore, before committing to sending the phone out to either HTC or Vodafone to look at, i tried my own hard-reset of the phone.  Without access to remove the battery, i simply discharged the battery completely (wifi,GPS,Bluetooth,NFC,active call).
Now, plugging in the phone to charge, i found that i could enable a hard reset (holding down power and volume down) i get a basic text interface with option to do a hard reset.  This was sucessful.  Clearly this is a much stronger version of the factory reset than via the menus.
My phone is now set up again and working happily, and i dont need to send if off for "repair".
Possible causes
My feeling is this was a piece of malware, although i have no direct proof.  As a resource to assist others, below i list the most recent apps i downloaded.
/Trigger: SMS Plugin/NFC ReTag FREE/No One Dies/Rightmove Property Search/Contacts Optimizer/Google Keyboard/AnyTag NFC Launcher/Proxy Settings/Aix Weather Widget/Bright Weather/
In hindsight, i accept that some of these are from lesser-known sources, albeit all acquired via the play store, i didn't pay close attention to the permissions.
Summary
My primary motivation for posting here is because i failed to find useful advice yesterday when i needed it.  Many others have posted about this message, some also suspecting malware, but most say a factory reset solved the problem.  I hope to add to the situation the following new pieces of information
1) Eject and reinsert of the SIM card to proceed when frozen
2) Running the battery down as a method of doing a hard reset, if the other method fails
3) A list of apps i recently downloaded, might help point towards a possible source of malware, albeit useless until compared with other users who encounter the same problem.

someone is able to remote access my sony phone touchscreen even when in in airplane mode. how could that be possible?
My phone has been hacked. Through a hidden network the hacker seems to be accessing my touch screen remotely.
But this happens even in airplane mode. How to truly disable all network activity ?

Could you provide more information about "accessing my touch screen remotely"? What happened and what did you observe?

Yes please do provide some additional detail. Does this happen when at home, work or where?

I don't think that your phone has been hacked.
If the actions your phone is doing are random, you might be experiencing issues with the touchscreen or with its firmware. Consider factory resetting your phone and look if the problem does still exist.

How to change the Google Play email
I recently have gone from IPhone to Android. And my Google Play store is under an old email that has deleted its self. I have a purchased app that I need for school on this account, is there a way that I can change the email on my GooglePlay account without having to make a new account?

Settings > account > google > *menu button > Add account.
Then go back to google accounts and delete the one you don't want.
This will change your play store email!.
*also, it may be slightly different on different roms. I gave you the most common method.

If it is stuck in bootloop, I suspect corruption in /system. You should either reinstall the stock ROM or install a custom one. The first thing you will need is a custom recovery. According to this post by flowish at XDA-Developers, you can do this by follwing these steps:

Download the recovery (recommended latest build)
extract and put to your /sdcard
open terminal applications (like better terminal
  emulator) ,or you can use from adb shell and type :
$ su
# cd /mnt/sdcard
# sh install-recovery.sh
# sh reboot-recovery.sh

Here is the button configuration of the recovery:

Power button : Select
Volume (+) : Up
Volume (-) : Down

After doing that, install a new ROM from the recovery. Here is a custom ROM (from a post by nizar07 at androidtablets.net) that you can install from recovery.

Thank you for your reply. It is not stuck in boot loop. When I start the tablet, it shows a small android icon at the center of the tab and freezes there. It does not boot, it just stays there until I press and hold the power button to switch it off..........
When I connect the tablet to my computer with the usb cable, the computer does not recoginze it, neither does it ask for any drivers............
Power button + VolUp + VolDown button does not boot it to the recovery.........
Now I am thinking why did I do a factory reset :(
Can you advice what do I do next?

Where did you perform the factory reset from? The settings app?

Yes.. from Settings -> Reset -> factory and ever since it is not booting and halts on the small android icon. If I connect it to the computer, it does not even detect the tablet and does not ask for drivers.

When you connect it to the computer, does it charge? If not, does it charge from AC? Is there any way for you to know that it is charging?

when i connect it to computer or AC power socket, the screen comes up with the small android icon. i dont know whether it is getting charged or not. Earlier a small blue LED light use to appear indicating charging but now it is not. If it is not connected to computer or AC, I can power it ON by pressing the power button but it halts at the small android icon that means it is charged. Right?........... I cannot even find a key combination to put it into recovery. i tried lot of combinations. The physical buttons on the tab are: Power, VolUp, VolDown and Back button at the bottom center.

When is "earlier" when the blue LED lights up? Before or after the reset? What we are trying to accomplish right now if either connect to adb or boot anything other than that little android icon (eg. recovery, test mode).

This is turning out to be a very weired problem. Few positive things happened that I described in the second answer. Now there is a new problem and I have started a new question. Here is the link http://android.stackexchange.com/questions/91664/unable-to-start-chinese-tablet-even-after-installing-recovery

I dont know what happened but surprisingly the tablet booted on its own. I did not do anything new. It is showing in Device manager as Alcatel ADB Android Device and I was able to see the memory card contents in My Computer too. Battery level was 74%, battery charging blue LED came back on,  phew!
The only negative thing I saw was that it gave a message on Root Checked app that device is performing very slow. RootChecker said that the device does not have root permission.
Now first thing what I wanted to do was... rooting the device. Here are the steps what I followed:
1. I saw your answer but I dont know terminal applications or adb shell so I configured Play Store and downloaded ClockworkMod ROM Manager - When I tried to install the recovery, it said, recovery for L26 device is not available
2. I then downloaded an utility from srsroot.com because my tablet was listed in the supported page ( http://www.srsroot.com/supported as unknown - L26 - Ubuntu-L26-B-20121016 - 4.0.4 ). There were few buttons Root Device (all methods), Root Device (Smartroot), Reset User Lock, Reset Gesture Lock, Read Gesture Lock, Reset Gmail, Wipe All Data, Reboot Device, Reboot Recovery - To be on the safer side, before rooting, I thought let me check if srsroot utility restarts the device, so I clicked Reboot Device and it restarted.
Refreshing moment came to an end. Now I am back to the same issue.... SRSroot utility rebooted my tablet but again it is getting stuck at the small android icon :(
Now do I need to wait for the magical moment to happen again or is there anything I can do?
Thank you for looking into my issue...

Do you have an external SD card? I am not sure if you would be able to reproduce a boot, but put the ROM that I posted in my original answer onto the root directory on your external SD card. You should be able to boot into recovery and flash it from recovery. At least we know that your tablet is not bricked.

reproducing a boot is a problem... I can flash the rom once it goes to recovery. It does not go to recovery mode :(

Honestly, all we can do is hope that you can "magically" get it to boot again.

formatted tab 3 10.1 and cant install android from twrp
got a problem with my samsung tab3 10.1 (5200), installed twrp and rooted the device and after that i formatted it in twrp to install a fresh android on an empty tablet. But install couldn't work , the installer couldn't make directories data and others so the install did not work ( took about 2 minutes) but at the end it says succesfull.
It cant boot past samsung logo because i think nothing really installed.
Anyone has an idea to try and install in another way ?
I'm trying to instal cwm now but says md5 hash invalid and same with the twrp file which is on the device.

already found the problem guys, after the format  it sayd you best reboot the bootloader  so i did that and then it could read and write, it's up and running without the latest offcial update that crashed a lot.
rooted and deodexed whatever that means.

force headphone mode
When I plug in the 3.5mm jack and play back media, headphone mode keeps toggling, resulting in audio cutting in/ out every second or so.
Is there a way to force headphone mode or disable the 3.5mm jack detection?
I tried a couple of apps and searched the web but people seem to want to force speakers rather than headphones, so no luck.
(Android 4.2.2 Samsung Galaxy Tab 3 Lite)

First off, you require root. Then Install Xposed Framework and Install an app ( forgot the name but do a quick google search for it and you will find it ) which lets you override your deafult actions when certain things happen like  plugging in the headphone. Then you can set that action to anything you want.

How is my friend bypassing Applock application
I'm using moto x 2nd gen, I recently installed applock to keep some apps private but one of my friend knows a way to bypass the password and even change it, he did the same even with pattern lock. He doesn't even reboot the phone, he does it in seconds. How is he doing it and in what other ways can I lock my apps?

Have you thought about asking him?

Could you link the app? There are some apps that have similar name like "AppLock", is it the one by DoMobile?

One possible answer can be that he is killing the application process that is protecting your device. One possible way is that he goes to Settings->Apps->[applock_application] and then Force Stop it.
Go to this link for more detail.

I've locked settings and play store too.

There are many ways to bypass applock, you can reboot into safe mode, uninstall/force stop/clear data the applock (if Settings is not locked), widgets (some apps have a Task Manager widget or Enable/Disable app widget), using third party application to uninstall/force stop/clear data the applock, uninstall the applock from Google Play Store (if Play Store is not locked), if Play Store is locked, open Google Play Store website from any browser, then uninstall the applock, etc. These only works on non-system applock, to bypass system applock, you have to disable/force stop the applock, or factory data reset.

He either knows your pin and your pattern or He killed the apps process ( applock ) to bypass the pin or he set "destroy process after user leaves it" in the developer options.

He can't stop the app process, I locked the settings too.

What's mnt in misc in internal storage?
On an Android device, checking storage in the normal system settings, it reports that only 7.9 MB out of 1.29 GB of internal storage is free. It lists 1.20 GB of Misc files.
Checking the misc files, there's a an entry mnt that makes up 1.20 GB. At first I thought that this was equivalent to /mnt, but looking more closely there's a mounted SD Card with 20.27 out of 29.71 GB free. So it shouldn't be the SD card.

What is the mnt entry?
Can it be safely be deleted to free up internal storage space?

Further complicating issue: I'm helping a friend on travel on another continent, so I don't have direct access to the tablet.

What is the location of the "misc" mnt file?

AFAIK I can't see the location from the storage menu.

How can you tell that there is 2 different "mnt" files/folders? Have you tried using any disk usage apps?

I can't tell, except that this one is listed under misc files in internal storage. No, haven't tried any disk usage apps. Anyone you recommend?

Disk Usage & Storage Analyzer It's free and no ads

Did you tap on misc in internal storage in device settings? It should show the files in there. But try the link

What is the difference between these two persistent notifications?
I use two apps which require a persistent notification: (1) the Pebble Smartwatch app, and (2) Tasker. When I pull down the notification bar (see screenshot), I see both notifications.  However, only the Tasker one shows an icon when the notification bar is hidden, and likewise only Tasker shows a slot on my lock screen.
What is the difference between how these apps are showing their persistent notification?  From my understanding, if an app wants to run continuously, it MUST put a persistent notification on the notification bar. But somehow the Pebble app is not requiring an icon or displaying on my lock screen.

These behaviors can be controlled when an app builds a notification.

From my understanding, if an app wants to run continuously, it MUST put a persistent notification on the notification bar

You're pretty much correct until the "notification bar" part. Both of notifications are indeed persistent (i.e. on-going, cannot be removed manually by user). Take note that there isn't a button on notification drawer for clearing all non-persistent notifications.
The difference, however, is the notification's priority. This setting is independent of whether the notification is persistent or not. Usually, persistent notifications are set at least to default priority to "keep users informed about an ongoing process in the background". However, if a notification is set to minimum priority, it won't appear on notification bar.

Priority: MIN
Use for contextual or background information such as weather information or contextual location information. Minimum-priority notifications do not appear in the status bar. The user discovers them on expanding the notification shade.

Another example is Google Now's notification for weather & traffic, but it isn't persistent.

Can't do factory reset on Galaxy Tab 2
I can't reset my Galaxy Tab 2 to factory settings. I know that you can when turning it on but the problem is that I installed a sort of ios onto the device and have forgotten the password and it won't let me turn it off without being logged in, but I can't unlock it.
Please help

According to Verizon, if you cannot perform a factory reset from the Settings app, you can perform one by following these steps:

Power the device off.

Press and hold the Power key.
Select Power off.
Select OK.   Note: If the screen doesn't respond to input, press and hold the Power button for 10-15 seconds.

Press and hold the Volume up key then press and hold the Power key.   Note: USB cable must be disconnected.
When the Samsung logo appears, release the Volume up key and Power key.
From the Android system recovery screen, press the Volume keys to select wipe data / factory reset then press the Power key.
Press the Volume keys to select Yes -- delete all user data then press the Power key.
Press the Volume keys to select reboot system now then press the Power key.
Perform Initial Activation and Setup.

You can read more at the Verizon website (Tab 2 Troubleshooting: Hard Reset).

You can wipe your phone straight from your computer using Android Device Manager, by going to the Play Store website on your computer, clicking the settings button, and selecting Android Device Manager.  Then, select your phone if it isn't automatically selected, and click wipe.

What if my device isnt connected to device manager

If you haven't set it up on your phone, then this won't work, but if you mean that it just isn't connected to WiFi, then once it is connected to a network it will factory reset it.

How can i run At-commadns with the ADB?
I'm trying to communicate with the modem of my Samsung Galaxy S3 GT-I9300 over the ADB tool. My galaxy is rooted and is accessible through adb.
I'm attempting to execute AT-commands over the adb-tool.
I already tried a few AT-commands but the modem doesn't respond.

First of all I was running cat /proc/tty/drivers to get the right driver. my output:

root@m0:/ # cat /proc/tty/drivers
/dev/tty             /dev/tty        5       0 system:/dev/tty
/dev/console         /dev/console    5       1 system:console
/dev/ptmx            /dev/ptmx       5       2 system
/dev/vc/0            /dev/vc/0       4       0 system:vtmaster
rfcomm               /dev/rfcomm   216 0-255 serial
g_serial             /dev/ttyGS    250 0-3 serial
usbserial            /dev/ttyUSB   188 0-253 serial
s3c2410_serial       /dev/ttySAC   204 64-67 serial
serial               /dev/ttyS       4 64-67 serial
pty_slave            /dev/pts      136 0-1048575 pty:slave
pty_master           /dev/ptm      128 0-1048575 pty:master
unknown              /dev/tty        4 1-63 console

Consequently my driver address is /dev/ttyGS0, so I run the next command echo -e "AT\r" > /dev/ttyGS0 but the modem doesn't respond and nothing happens:

root@m0:/ # echo -e "AT\r" > /dev/ttyGS0
root@m0:/ #

So I quit the tool and tried another command service check phone:

130|root@m0:/ # service check phone
Service phone: found
root@m0:/ #

It looks like it at least found a kind of a modem.

So, I Google a bit and I find a nice tool called microcom, which is included in busybox. I installed busybox and tried busybox microcom -t 5000 /dev/ttyGS0, but the output was

root@m0:/ # busybox microcom -t 5000 /dev/ttyGS0
microcom: applet not found
1|root@m0:/ #

I really hope you can help me to find my problem with my code or suggest some better commands.

Use this version of busybox, it will have microcom.

How to shrink a notification in notification bar in Android Lollipop?
I was used to shrinking and enlarging notifications for more buttons in former android version - Kitkat. Now with Lollipop I am unsure how to execute this. I want to shrink notificaitons with buttons if I do not want to use them (i used to be able to do it).
Formerly I did it by holding notification for a sec and then pulling it down to enlarge or up to shrink. It seems like it works down to enlarge but I cannot shrink. Is there a different way to do it? Or does Android decide when to make it large or small (if yes that is a sad thing)

You can shrink a notification by pinching in horizontally on the notification. Likewise, you can expand one by pinching out horizontally. You can see this in my beautifully-drawn diagram:

EDIT: You can also swipe up/down using two fingers instead of one. Thanks to eldarerathis for this addition.

Wow this actually works, thanks! And wow that it just the most stupid non intuitive way to do it. What a bad design decision. Thanks again though

It is definitely not the smartest way to design it, especially since the old gesture was so much more convenient.

Or swipe up/down using two fingers instead of one.

I can swipe up and down with one finger, and 2 always worked on KK and works for me on Lollipop now too!

resetting my Nexus 7
recently, I downloaded Android 5.0 on my nexus 7. I hate it, and want to reset my tablet. If I do, will that take me back to the original factory setting (4.1), and if so, can I upgrade to 4.4 kit kat?

No resetting will not put you back on any previous versions of Android. In order to do that you will need to flash whatever version that you want.
I suggest using Wugfresh Nexus Root Toolkit for downgrading. If you decide that you want to go back to stock, unrooted, and locked bootloader you have that option as well. This toolkit will be able to unbrick your device, if needed. It has all the necessary tools to do all the steps to flash another Android version. Plus it'll do the recovery, kernel, and bootloader as well.

"Resetting" your tablet would only perform a factory reset, which only wipes /data. In order to downgrade, the /system directory. In order for you to downgrade Android versions, you will need to install a custom recovery and flash the stock image.
To install a custom recovery on the Nexus 7, please see the Cyanogenmod Wiki page for the Nexus 7 and follow the instructions there.
Once you have a custom recovery, you can download the 4.4.2 OTA for the Nexus 7 from your recovery.
Note: The links provided are only for the Nexus 7, WiFi edition, codename grouper. Attempting to use this method on the Nexus 7 2013, codename flo, may result in adverse effects.

Low call volume on Nexus 5 Lollipop
After upgrading my Nexus 5 to Android Lollipop, the volume in call is extremely low. I've compared it to my girlfriend's exact same Nexus and she hasn't got any problems. Is there a solution to this? I searched everywhere and couldn't find a solution.
The volume was perfectly fine before the update.

Backup your data and reset the phone.
I had the exact same problem, the way I fixed it is by doing a factory reset. To nail down the problem, I booted up the phone into safe mode (Long press the 'Power Off' on your power menu). There, it was better, so I decided to wipe my phone and recover my data afterwards using TWRP. Also, you should note that 5.0.1 sort of improved the speakers - both of them, the earpiece and the actual speaker.

Without any explanation about possible cause of the issue, I'd say this is the last thing OP should do though.

I agree with Andrew, though I can see a possible explanation (many users reported issues following the LP upgrade, which were fixed by a factory-reset). When throwing in such an action, you should always explain the background – as backup and restore are a time-consuming task most times.

Add apps to default Guest account on Lollipop
I like the guest account feature on lollipop, but I would like to add apps to the account, so that a guest can use more than just native google apps, that I have available on my device. I know this was working in KitKat with a "new user". Is this not possible with just the "guest" user? Do I have to create a new user for that? Are there any drawbacks for having such a "hard guest" account for this purposes on a device? Like a considerable CPU/battery/memory impact?
(Nexus 7 2013) Android 5.0.1

No issues if you sign up with a new guest Google account.
Make a guest user ID for Google services in the guest session, and use the guest session as a normal session.
Though it shares the device storage ( for apps installed ) but not RAM.
Hence, both sessions' RAM usages are separately managed for each other!
I tried that.
while my account showed 1GB free, guest on the contrary showed 1.8GB free!
Impacts:
Google is smart, and this feature has been made way better now in Lollipop than in Kitkat. So dont worry, everything is managed effectively by the system.

Just to clarify, what do you mean by making a guest user ID for Google services? Will I be able to share the apps? Or will I have to install new instances within this modified guest? Or instead of downloading will it use the downloaded data of the app in the other account?

@Ev0oD Yeah by "Guest ID" I just meant, make a new google account; like 'abcdefguest@gmail.com' or anything that you can remember. So that way, you are able to enable your guest users to download apps from PlayStore. And also, your Main account and Guest account will no way interfare with each other.
So, actually you end up making a completely different set of Users similar to Microsoft Windows!

Adding a restricted user seems to be, what you are looking for.
This should work in Lollipop tablets.
After creating such an account you can select which of your installed apps are usable by that account.
Sadly that feature does not seem to exist on Lollipop smartphones though.
There is a workaround though that may also suit your needs.

This is what I mentioned in the question by saying "new user" in KitKat. I know about this, but it does not behave as guest, because it keeps state (as if it was a shared owner of the device). I also stated more subquestions which you left unadressed.

@Ev0oD I added a link to my answer to a workaround. There I also did describe the memory impact. And IMO you have to create another account for this.

By memory impact I did not mean storage capacity requirements, but RAM overhead. But I appreciate the efforts

Will upgrading a Nexus 4 to Android 5.0 require a "reset"
My Nexus 4 has been bugging me that a new Android is available, since a few weeks.
However, I read somewhere that upgrading would make me lose my data and have to re-install everything. Is that really the case ? (I find it strange that it would be so insistent, if it were true that this causes loss of data/setup).

If it's about OTA, and your device is not rooted, then it won't reset anything.

It might not be required by the update itself. But according to the bunch of related error descriptions popping up here since the start of the rollout, you might be required to perform such afterwards, in case you experience trouble.

There are two ways you can upgrade your device to a latest version of OS:

OTA (Over The Air): This type of upgrade will automatically take care of all the steps required to update your system. The once which you are bugged with is OTA update. One needn't erase data while upgrading using an OTA.
Flashing your device: Usually Google releases device specific factory images on its developer website along with the OTAs. But for this, you will need to erase all the data on your phone and install the factory image.

In your case, you have received the OTA and it's ready to install, and hence shouldn't be worried of losing your data, neither you will be asked to re-install. However, it's always better to have your data, app data, etc. backed up for the worst case scenario.

Thanks, this makes sense too. The warning I read must have been from early adopters.

I am using nexus5  with android 5.0. But in fact i cannot use the Google now service that says that network error. I had already search about this problem,  but no one can really solve it? Does any one know how to fix it?

Does it work on WiFi?

@KaranRajBaruah no，in any connections

Is Google by any chance blocked by your internet provider?

@AndrewT. it is right。 but ihad already a Vpn service before use google and it is gobal vpn and ican visit any google sites

Could you connect to Google using their apps? (e.g. Play Store, Google+, GMail, Maps). You should update your question by mentioning the VPN. Last time I had a problem accessing Google Play Store with VPN.

all was well,it was working fine and suddenly it stopped working.sign-in error.nothing could fx.no booting, force stopping, nothing..nada

Try this go into settings/apps/under the "ALL" tab scroll and tap on google app/ force stop, and clear cache. power you device off and back on. Test and you should be good to go.

On the Samsung Galaxy S5, how do I change the default USB connection type?
Right now when I plug my S5 into a computer, the USB connection defaults to 'installer'. I then have to pull down the notifications menu and switch it to 'MTP'.
I'd like it to default to MTP, so I don't have to fool with the phone after plugging it in.
Phone is from Verizon, and Android version is 4.4.4.

You have to enable the developer options, which allow setting a default USB mode.

you can try this code on the dialer, it will then go to a page called USBSettings, there, you can change the connection type
*#0808#
try dialling this again if the first time it just erases text

How to start a hotspot automatically on device boot
I have an Andriod based TV box connected to the internet via ethernet. I have enabled a portable wifi hotspot (so basically it acts as a wifi router). But every time there is a power cut to this device I have to re-enable the hotspot.
Basically want to save the tethering configuration so that on a reboot the device boots in tethering mode, i.e., the last configured state.

Welcome to the Android Enthusiasts! I'm not 100% sure if all required settings could be made this way (especially as you didn't list them), but it could be accomplished using an automation tool like Tasker, which feature to run tasks on events like BOOT_COMPLETED. Worth a look at least.

@JohnDoea I had a written a tasker method, don't know if wanna check it out?, I will temporarily enable it for you to see if that's what you are looking for..

Android Samsung TAB e auto turn on Hotspot?

Use MacroDroid instead of Tasker, as it is more user friendly and the  UI is good.
Here are the steps:-

Open MacroDroid, click on the button "Add Macro", then select the trigger "Boot completed".
In the next screen, select the action "Turn hotspot on", then save the macro.
Reboot your phone.

You will see hotspot will be activated automatically after a reboot.
I used this method for an old 3g phone to create my own WiFi hotspot.

You can use Tasker (7 day trial available) to accomplish this:
Objective: Auto switch-on  mobile hotspot after boot
Profile (or Trigger)
Create a Profile which allows triggering of the Task after boot:

Go to Profiles Tab and click  "+"
Event  → System  → Device Boot
Tap back to exit from this window

Task
You will notice as soon as you exit, you will be prompted to link this Profile to a Task;

Scroll all the way up the Task list select "New Task + "
You can name this Task AutoTethering or anything.
Click "+" to add new Action
Net  → WiFi Tether (Set On)
Press back the way all back until you exit Tasker (your profile is now saved and is ready for execution)

Extras: Give Tasker more priority (allow auto-start for Tasker, exclude from battery optimisations, task killers etc)
Explanation: Soon after boot, the first action  turns on Wi-Fi tethering (note:  Tasker already has a built in WiFi Tether variable which is capable of handling tethering state)
This should work. (tested)

Xavier, I cannot reply to you in comments, I am sorry. I gave you the bounty.

@JohnDoea That's okay BTW thanks for bounty!

The previous 2 answers use Macrodroid and Tasker. To accomplish the same process with Automate, do the following:

Add the "Broadcast receive" block. Click on it, in the section, select "Boot complete". Click "Done".
Add the "Wi-Fi hotspot set state" block. Click on it and select "On". Click "Done".
Link the blocks. Clcik on the check mark at the top. Give your flow a name and the necessary permissions.
In the settings, enable "Run on system startup".

Your flow will look like the following image:

When the device restart, the hotspot will also automatically starts.

Why are my call settings disabled (and which settings require operator support and which settings are normally included in service plans)?
As shown in the screenshot below, on my Samsung Galaxy SIII, when I go to Phone -> Call Settings, almost everything is disabled/grayed out. I have a SIM card inside my phone but have not topped up my mobile phone subscription this month. I wonder whether that is the reason why these features are disabled, or whether the reason is that my network provider doesn't support them (after all I am still able to receive incoming calls and SMSs). Is this the case?
I would like to use features such as:

placing a call on hold, retrieving a held call, and dialling second (or other) calls
make multipary/conference calls by merging calls
set call diverting (including diverting calls to the voicemail server)
set call barring
set call waiting
set call forwarding
set fixed dialling numbers (FDNs)

I wonder which of these features require support for these features from the network operator. I also would like to know whether, and if not then which of these, features are nowadays provided free of charge with a subscription plan from the network operator, and which features normally would not be included and cost extra. Receiving phone calls and SMS messages does not require the account associated with the SIM card to be topped-up (hence is totally free of charge). I know this could vary from network operator to network operator, but due to network operator competitiveness, I would expect most network operator to provide more or less the same features for free as others, and charge for features in case the other operators also do.
Thanks.

EDIT:
I've topped up my phone with my pay-as-you-go plan and as a result all of the entries in the above screenshot have become enabled.

EDIT:
Just for the record, I've contacted my network operator. The monthly 10€ pay-as-you-go plan I'm subscribed to happens to include 400 phone hours within the same country, 400 SMS to phone numbers within the same country, 1GB fast Internet followed by unlimited slow Internet. However calls abroad as well as calls to the provider's answering machine service are charged separately/extra. Also, while Caller ID and Call Forwarding/Diverting services are free of charge, Call Waiting will soon incur charges with my provider. I guess other service providers would offer similar service and features at roughly the same price. Regards.

I'd first ask the network operator. Most of what you've listed are "service features" the operator needs to explicitly support – so it might well be that's why they're disabled in call settings (they might be detected as "being absent").

Thank you for your answer. Besides my particular network operator, I was also interested in knowing which of these services are included on average by most network operators with the most common basic pay-as-you go plans and which ones among the services I listed tend to cost extra nowadays. Thanks.

That's no question fitting this site (off-topic for being "Android independent"). We don't cover "all about cell phones" here ;)

Sorry, I thought those features would have had to have support from the Android OS to function properly, plus the screenshot I posted is Android specific. Plus, I couldn't find a more suitable site for this post. Sorry for the post.

You've got me wrong: Your question is fine. But what you've asked in your last comment ("which of these services are included on average by most network operators") would be off-topic here.

The reason for this is because airplane mode is on.
Turn off airplane mode, and all those settings will be available.

How to avoid Clash of Clans update and go right into the application?
Whenever I open Clash of Clans, it gives a popup saying,

Update is available!

Good news! A new version of the game is available

There is no cancel option. No matter if I click the back button or tap outside the popup, it always leads me to Play Store page.
How do I avoid update and continue playing?

It seems there is a version check inside the app. The only thing that I could think of is to use hacked APK, but that can be considered as cheating and thus, illegal and off-topic here. I couldn't provide any answer, you may wait for other answerers if there is a legit way to do that.

If they have locked it to version checking (entirely possible as it has an online component IIRC) then you will probably have to update it! As Andrew said anything else would be illegal, and again would possibly run into issues like this anyway. Is there any reason you can't update it? Also it might be worth contacting the developer and asking them about this. Use the contact link in the Play Store, not a review.

@RossC sure. I will.

Bad news: For some apps, especially games, you are not allowed to play without updating it -- especially if it is connected to the net.
You will not be able to legally bypass this restriction.

Samsung Galaxy S2 recites any actions that I do. How to turn it off?
My phone won't stop talking. It won't let me scroll or see other settings, I've tried to go back the way I did and turn it off, but I can't scroll down or up. I have to double click on applications to open them everything I touch. It speaks to me what I touched. How can I reset that?

Did you try AndrewT's answer after his edit?

There is a big chance you turned on TalkBack accessibility option by accident. You may want to turn off to fix this "issue".

Enable or disable accessibility services.

From the Home screen, touch Applications  > Settings > Accessibility .
Touch Accessibility to toggle a checkmark.
Touch TalkBack to toggle a checkmark. When enabled, recites menu options, application titles, contacts, and other items when scrolling and making selections.

If an Attention prompt appears, touch OK to continue or Cancel to exit.

(copied with slight modification)
To scroll when TalkBack is active, use 2 fingers when scrolling. From Google Support

Tip: To scroll across screens, use two fingers along the screen.

Where are the drivers for Windows computers located on an Android phone?
Im talking about the drivers that install when you plug your phone into a Windows computer.

Windows comes either pre loaded with fitting (generic) drivers or you'd need to download them from the manufacturer. But all this heavily depends on your device' make/model.

Which specific phone are you asking about here?

They're not stored anywhere on your phone. Windows finds and downloads them from Windows Update when you plug your device in. If an appropriate driver has already been downloaded and installed previously (or shipped with the Windows installation), it will use that and skip the download step.
Without Internet, and in the absence of an appropriate driver already being present on disk somewhere, the driver installation will end up failing.

What about when there isn't any internet? ( just asking)

@HasH_BrowN: If Windows already has a driver downloaded that it thinks is "appropriate" then it will use that. For example, multiple Nexus devices could use the same Google ADB driver. Otherwise the driver installation just fails, as far as I recall. You'd have to either connect to the Internet or manually install a driver you had on hand (on a disk, etc).

10-4.  Just some more info to help others out. Thanx. :)

Drivers are actually frequently stored on device mass storage, and can even be picked up and installed by Windows automatically.

email adress on facebook app
How do I make the facebook app "forget" my e-mail address? It's driving me insane... Since I'm a little paranoid, it seems that if I lose my phone, all anyone has to do is to enter my password into my "undeleteable" facebook app e-mail login address.
So, am I clear enough? I've tried clearing the data, clearing the cache, but EVERYTIME I open the facebook APP, THERE'S MY FREAKIN' E-MAIL ADDRESS!!!

Your email address is stored as part of a "user account" on the device.
Settings => Accounts => Facebook : Menu => Remove Account
After clearing your cache and data for the app, and removing the account, your email should be removed. But, every time you log in it will add the account back into the settings.

My android tablet is not working
My android tablet is displaying an error message 'Unfortunately, the process com.android.phone has stopped'. The message occurs so quickly that I am unable to touch any application.

tabloid, huh? :p Have you tried booting into Recovery Mode (hold down Power + Volume buttons)?

Try this:

Quickly press OK on the error dialog so you can follow the rest of the steps.
Navigate to Settings > Apps > All.
Scroll down to Phone and click it.
Clear cache for it. If the problem persists, clear data as well.

If this does not help, try clearing cache and data for the Sim Toolkit app as well.

The only way I know to fix this problem is to restore to factory settings in Settings-Backup&Reset.

If you suggest that, you should a) provide a reason why it should help, and b) name the implications (here: all user-installed apps and all data will be gone after that).

Oh, apart from that, your proposed solution cannot work for the OP. Question says: The message occurs so quickly that I am unable to touch any application. So no chance to reach that menu.

Recovery mode > factory reset and
Clear cache

If you suggest that, you should a) provide a reason why it should help, and b) name the implications (here: all user-installed apps and all data will be gone after that).

Unlocking Sony Xperia Z3 Compact with gloves
I've read that, if I turn on Glove mode, it will increase sensitivity of touch if I unlock my phone with gloves on. But it is not working like that. Since I'll turn Glove mode on it has increased sensitivity no matter if I have gloves on or not.
Is it possible to do it so it would increase sensitivity only if I'll UNLOCK screen with gloves on?
Thanks in advance!

Are you sure there's not a misunderstanding here?

I found it on several pages: http://forum.xda-developers.com/showthread.php?t=2313539 "unlock the screen wearing gloves

Android 5 update randomly aborted on my Nexus 4
I have a Nexus 4 phone. It's not rooted nor customized with any mod.
Today I (finally) received the update to Android 5.0.1, which I downloaded. After the download, I clicked on the Restart and install button (my phone's in French so translation might not be exact). The countdown before restarting the phone then began but after a few seconds I have been redirected to a screen telling me my system was up to date.
I tried to search for updates but nothing showed up and now I have no idea where the heck the update went. My phone still displays Android version 4.4.4 and is visibly still running Android 4.4.4.
What am I supposed to do now?
Thanks for your help.

You could use the Nexus Root Toolkit to sideload the OTA updates.  Links:

Nexus Root Toolkit
Nexus 4 OTA (LRX21T from KTU84P)
Nexus 4 OTA (LRX22C from LRX21T)

Hit Launch in the Advanced Utilities pane, then hit the Sideload Update button, and point to the OTA zip from above.  Follow the instructions.  No typing involved.
I don't know of a single LRX22C from KTU84P OTA.

Nope. No other setting is required. You should be able to login fine with the credentials.
I'd recommend double checking the password you typed for any mistake or just reset password incase you may have forgotten.

Boot on charge for Huawei g70
Can somebody help me on how to make Huawei G730 to boot when connected to the charger? I've founs a tool to do this on Samsung that doesn't work on this phone.

Try this:

Install ADB and fastboot. If you already have the Android SDK, you can find these tools in dir_to_sdk/sdk/platform-tools/. If you don't have the SDK, here is a direct link to Minimal ADB and Fastboot (for Windows).
Install your device drivers if applicable.
Run the following code from your ADB/fastboot directory:
fastboot oem unlock
fastboot oem off-mode-charge 0
fastboot oem lock
fastboot reboot

Where is the message center on Moto G?
I have a Moto G and I am not able to send messages, not able to find message centre. Where is the message centre?

Summarized from Motorola forum, Moto G and Moto X are designed in such a way that it will take the message center number automatically from the Saved configuration of the SIM. Try changing the SIM from Slot 1 to Slot 2. Save and set as default for newly received configuration settings.
You can try the following method by SmaRkieS on Android Geeks:

Dial *#*#4636#*#*.
You will get a menu. From that, select Phone Information. You will find
  a setting "SMSC". Refresh it. It is most likely to retrieve the
  message center number from your operator (or call your operator, and
  get the message center number, and then update in this field), then the
  problem should be resolved!

Globally disable vibration?
Is there a way to disable vibration on HTC One M8 regardless of individual application settings?
I can't conceive of a situation in which I would ever want my phone to vibrate so I'd just assume kill it at the source, if possible. If no soft solution exists I may need to resort to ripping the motor out.
To any hardware engineers out there - build a phone without vibration and I'd buy it in an instant.

Sure!
Though a rooted device is needed, and in the case of HTC phones, probably also s-off. Just download VibraFix, which will allow you to completely turn off vibration. It will also allow you to pass through calls and texts, if that is needed.

I've made an app that can disable/enable vibrations system-wide because Android lacks such option for inexplicable reasons - Global Vibration Toggle.
It requires a rooted phone as well and has a widget toggle and an automatic mode.

help on rooting Note 3
I'm trying to find a way to root my phone so I can delete these factory installed apps, make my phone faster etc.
Can someone tell step by step on how to achieve this? Do I need to download something? Etc

By rooting your device you will lose your warranty and during this process you may brick the device. You are doing it at your risk.
According to XDA Developers you can use the CF-Auto-Root tool to root Galaxy Note 3. The following instructions come from Chainfire's post.

Do I need to download something?

Yes:

Kies - this will install USB drivers
CF-Auto-Root - make sure you download the right file for your device model and Android version!
Odin

Rooting:

Your phone must not be connected to computer now.
Download CF-Auto-Root from the above forum link.
Extract the archive. You must end up with a file ending in .tar.md5.
Start Odin (look in the forum thread for download) and click the PDA button. Browse and select the previously extracted file.
Turn on phone in Download mode:

turn off
press and hold Volume Down, Home and Power
if you are asked to press a button do it

Connect the USB cable to phone and computer.
Do NOT check Repartition and make sure it is not checked!
Click Start in Odin.
Wait for it to reboot.

Another tutorial can be found here and includes pictures of the process too.

Adaptive brightness is not present in notification bar and altogether does not work
My Nexus 7 2013 has updated with OTA update to Android 5.0.1.
The notification bar has changed. Now when I change brightness, there is no button for auto-adjustment. It currently looks like this:

In settings, I can find Adaptive brightness settings - optimize brightness level for available light. However this does not work as expected. It just seems I have two different brightness settings. If I turn it on and set manually via notification bar to maximum, it is maximum, although the settings is ON. Then I turn it off and set it to maximum and it lets me do it too. When it is turned on, the brightness is just slightly darker than the turned OFF mode. However, it is always exactly as I set it with this small offset. It does not correspond to the external light.
It seems like it is a bug, but I can't tell. Do you experience the same with your Nexus 7 2013? Is the "auto" button missing in all lollipops? Does it mean that when you want to go to auto-brightness mode you have to enter settings and brightness via more like 5 clicks? (two swipe downs, settings, brightness, turn on)

It's the same with my Nexus 7 2012 on 5.0

Android has removed "Auto-brightness" in place of "Adaptive brightness" on Android 5.0 Lollipop.
From Android Police,

If you're looking for the auto-brightness switch on the Android L preview build, you won't find it. That's because it's been replaced with the adaptive brightness toggle. [...]
In short, adaptive brightness is like quasi-autobrightness. You're essentially setting a "range" of available brightness levels when this feature is turned on, so that if you have display brightness set to 50%, the phone may only actually adjust itself between 40 and 70% brightness in a given situation. This is as opposed to completely automatic brightness, which typically gives you the full spectrum of brightness adjustments depending on the ambient light. The problem with fully automatic brightness is that's it's often slow and a poor judge of what level of brightness your eyes really need. So, this adaptive mode allows you to set a baseline brightness that the phone will then adjust from based on your surroundings.

If adaptive brightness is active, it will be always active even if the brightness is changed from the quick setting panel, because it will only change the baseline brightness.
On the other hand, it's correct that there is no quick setting to toggle "Adaptive brightness" on stock ROM. It seems the only way to do that is with 3rd-party apps, but I didn't found any as of current writing.

It is adaptive brightness. Slider determines the sensitivity of the brightness in case adaptive brightness is turned on. If you keep the slider on 50%, it will work the same as auto brightness. If it is 30%, then the brightness will be equal to the brightness of the external illumination which is 20% less than current illumination. So, essentially it helps people save power or improve readability by adjusting the sensitivity of brightness according to individual preference

Rooting lenovo s920 after upgrading to kitkat 4.4.2
how can i root my lenovo s920 upgraded to android 4.4.2 . i have tried the Framaroot method , but it is not working.

While not being able to answer your question, I've added it to our rooting index – which you might wish to check for alternative methods.

Lenovo S920 and other Mediatek CPU based phones are an easy task, most of the time, to get rooted. There are several tools on the market that can do this with one click. Some of the are iRoot (previous name Vroot), KingoRoot etc. Beware because some of these tools have been uncovered that install malware as well. I have used iRoot in the past without any problems.

Try using towelroot to root the device. I've never had trouble with any of geohot's apps. Looking further into this it seems your device on 4.4.2 has a lot of issues getting rooted. I take no responsibility for what you do to your device (be very wary of installing malware onto your phone trying out all these sketchy root programs which may or may not work). Anyways, this was the only actual link I found describing someone who successfully rooted it (but it may be malware, the kingoroot is in my opinion - unsafe) http://kumaranmurugan.blogspot.com/2014/11/root-lenovo-s920-kitkat-442-8gb-row.html
Otherwise I've heard FramaRoot 1.6.1 works to root your device. Good luck.

Is there any solution for that ?  I looking for solution like this approach  - https://www.youtube.com/watch?v=jtKDpawgeLs (just button using) .

@Cornelius what does rooting have to do with this? To do a factory-reset via recovery-menu, no root is required. // URL87: You've used the rooting tag, but your question is about factory-reset. Accident or incident? Also, could you please [edit] your question and include an abstract of what's behind that link? Not everybody here can access Youtube (and furthermore, the video might be removed, or unavailable in some areas). One more thing to include: what have you already tried? What was the outcome, where did you get stuck?

Askmefast.com provides a hardware reset solution for that tablet:

Power off
Press and hold Power and Volume Up together
When it turns on (nothing may appear on screen or only the logo) release Volume Up (keep holding Power)
Keep holding Power and press and hold Volume Down

This should launch the reset mode and after a restart it should erase all apps and settings.

Is it possible to change the settings in android so that data is saved to the external SD card instead of the the phone's internal memory?
This problem has been annoying me for a while. When I download and install an app to my phone it defaults to the phone's internal memory. Not too big of a deal since I can move it afterwards. The problem comes after when the app has additional data it needs to install on to the device. That additional data always installs to the phone memory and I can't move it to the SD card.
For example: I install an app that is in total 1mb in size that I can move to the SD card. But the app downloads 300mb of data that stays on the internal memory that the app uses.
Is there a way to change it so that the data is downloaded to the SD?
I know that it's possible to re-partition the SD card and internal memory to make the internal memory bigger but I want to do that as a last resort.

there is a stack exchange site for andriod, probably that would be the right place for this question

The answer is NO.
You'll need to re-partition your SD to make your internal memory bigger.

No. The way android is set up, you have to install directly to internal. It's a part of the very core of the OS.

How to get old whatsapp account back without using the current cellphone number?
My Samsung Galaxy S4 recently broke. I've had a different whatsapp number and a different cellphone number. How do I get all my contacts back without using the current cellphone number but the whatsapp account number?

@AndrewT. The suggested duplicate has an answer only for when the phone number stays the same.

You will have to use the SIM for verification. Just pop the SIM into any phone and enter the old WhatsApp number during setup.
After a 5 min wait of trying to verify from the other phone(which won't work as the number is different) you will receive an SMS on the other WhatsApp SIM. Just enter the code received on this phone on the phone with the current SIM and you should be able to use the old WhatsApp account.

LG Optimus 4X HD - unlock bootloader?
I have just rooted the LG Optimus 4X HD using instructions I found at How to root the LG Optimus 4X (LG-P880)?
I now need to unlock the bootloader, but for some reason the command adb reboot oem-unlock does't seem to do what it should. All it does is reboot the device, and it boots normally again. Apparently it should boot to a screen asking if I want to unlock the bootloader.
Any ideas why this is not working for me?

That was my post (actually, with the JB update, rooting got even easier) – so maybe I can help you a second time:
Initial note:
IMPORTANT: Unlocking the bootloader on the O4X only works with Firmware V20 (approved for V20A and V20B; as OP hjust upgraded using the official tools, most likely V20C works as well). To check what firmware you're on, go to Settings › About Phone › Software Information – last entry there should read "Software version", starting with "P880XXY". If XX is a 20, you're fine; if it's a 10, you'll need to upgrade your device first.
Official approach
XDA Developers has a post describing the procedure. Requirements are similar to the ones in my "rooting answer", so you should already meet them. According to that "official LG procedure", the steps are as follows:

fully charge your device to 100%
connect your phone in LG software mode (or simply enable usb-debugging)
run: adb reboot oem-unlock

Alternative approach #1
As that failed for you (and not only you, others report that as well), let's look for an alternative approach. In another thread, XDA features an unlock tool for our O4X. I just found this now when looking for a different post – and wondered about the "relock" part: AFAIK, the O4X uses FUSEs for the lock status. Once blown, there's no way back. Obviously, that XDA member found a way around that (using a boot-loader hack): "by using this program you have 16 chances to unlock relock bootloader before all fuses blown".
Alternative approach #2
That's rather a "last resort" if everything else fails: Blow all the related FUSEs directly. Again described in an XDA thread (note the original/initial post has some errors, so here's a corrected version):

open a terminal (or use adb shell)
make yourself root (run su)
get the actual FUSE state by executing cat /sys/firmware/fuse/odm_reserved > /data/local/tmp/odm_reserved
in the created file, change the line 0x000000000000000000000000000000000000000000000000 00000040000000c8
write it back: cat /data/local/tmp/odm_reserved > /sys/firmware/fuse/odm_reserved

While this directly blows the FUSEs, it has one advantage over the "official method": No data lost, as no factory-reset is performed – a fact it most likely shares with "alternative approach #1" ;)
Check results
Whatever approach you took: You can check the results in "Hidden Menu" (dial 3845#*880#).

i should have also mentioned, in the hidden menu there is no bootloader status option

I've just checked: It is there ("Bootloader Unlock Check"). May I ask which firmware version you're on? I'm afraid all the above is only valid for v20 – not having the entry in HiddenMenu points to a v10 firmware.

I'll need to check in Monday as I don't have the device with me now. Where do I check?

Settings › About Phone › Software information should reveal it. Last entry there should be "Software version", starting with "P880XXY". If the XX is a 20, you're fine – if it's a 10, you'd first need to upgrade. Another indicator: Which Android version is it running? v10 = 4.0.3, v20 = 4.1.2. In hindsight: If my rooting answer worked for you, your device is most likely still running v10...

android 4.0.3
LG-P880-V10h-NOV-19-2012

Thought so (that was what mine was running until a few weeks ago). No chance to unlock your bootloader without upgrading to v20 before AFAIK. Mine is on V20C now. Battery consumption is horrible compared to V10H :( I'm considering to try a custom ROM, reports seem to indicate better battery time then...

OK, i've updraded it to 4.1.2 using the LG upgrade tool.
i've rooted it again (using your initial instructions).
now when i go to unlock the bootloader, the "adb reboot oem-unlock" command still doesn't work.
this time it appeared to just turn the device off.

OK, i had to use alternate approach #1 to unlock the bootloader.. the device is now reporting it as unlocked

Glad to read it finally worked out! You might consider accepting the answer then (click the check-mark next to it), as it solved your issue. This way others can easily recognize the problem has a solution :)

CyanogenMod 11 is a big laggy!!!

When creating a SMS with Google Search using my voice, Hangouts is not an option for sending
While driving, I may tell Google Search with my voice to "Text ".  Google will ask me what the message is, and eventually after completing the required back-and-forth, my phone prompts me to select an SMS application for sending.
I'm presented with Messages (i.e. the default Android SMS app) and Google Voice, but Hangouts is not one of the options.
In other applications where I may "Share" something, Hangouts is an option there.
This is on a Motorola Droid Turbo with 4.4.4 Android. My old phone, a Galaxy S3, didn't have a problem using Hangouts, if I'm remembering correctly (I could be wrong though).
I should also note that in my System Settings, Hangouts is the "Default SMS Application".
Any ideas on how to get Google Search to use Hangouts?
