Only notifications from text messages are being shown
As the title says, I only get notifications from my texting application but not from everything else.
A couple of examples:

I use pushbullet to share a website with my phone, but I won't get the notification until I open the app.
To see if I have to  manually open the app and refresh it, same thing with emails.
If I install an app on my device remotely from the play store, the app won't start downloading/installing till I open the play store on my phone.
Texting works as expected, i get notifications normally even with my third party texting app. (textra)

Specs:

Samsung Galaxy S4
SGH-i337M
5.0.1
Nova Launcher (if that matters)

It sounds like you've gone into the developer options and turned on "limit background processes", which stops apps running in the background to do all these things. The fact that they work normally when you open the app by hand suggests that app is still getting the information it needs, just not until it's in the foreground. The fact it's the whole behaviour of the app (e.g. Play Store downloading updates), not just the appearance of the notification tells me it's not just a problem with notifications.

I just checked and i didn't have them unlocked, so i did the tap thing to get them then dissabled them

Do any Android phones support 256GB of storage?
I'd like a phone, preferably Android, with 256 GB of storage.
To the best of my knowledge, no 256 GB microSD cards exist (despite a few scammy Amazon listings).  Therefore, the phone would either need to have (1) a fullsize SD slot or (2) dual microSD slots.  I don't know of any android phones that have a fullsize SD slot, although there are of course tablets that do.  And the only Android phone I know that promised dual microSD cards is the vaporware Saygus V2.
Do any solutions exist that don't involve solder or external devices?

In theory you could connect a Micro-USB stick to your phone that may have 256GB of storage, but you could easily use a Micro-USB to USB cable to connect larger storages (like HDD's up to 6TB), if you are able to supply the auxiliary power somehow.

Thanks. Unfortunately, I'm only interested in internal solutions. I'll update the question.

Just found out: Sandisk apparently sells 200 GB Micro-SD cards in their SANDISK ULTRA lineup, but remember that your phone has to support storage devices of that size (most of the current-gen phones are rated at 64 GB or 128 GB). Although I recommend buying multiple smaller cards, because together they will cost less than one big one.

Thanks! That is very close to what I need. (Multiple cards isn't preferred since I really don't like swapping.)

BTW, the consensus seems to be that SDXC cards over 64GB do work with phones like the Galaxy S4 under newer versions of Android, even if Samsung hasn't formally guaranteed support.

That's true, I know my Samsung Galaxy W was only rated 32 GB but worked with 64 GB. It's just not guaranteed. I'm sure the 200 GB card will work on most modern phones, but again those cards are cutting edge and I don't know if they are supported by your phone.

GiantTree, could you post your comment as an answer so that it can be up-voted and accepted?

Or you could use a HDD of 500GB or 1TB and connect it with you phone using OTG cable. It works fine in most of the phones supporting OTG(usb-on-the-go).

A quick search on Amazon gave a bunch of results.

SanDisk Ultra has a 256GB model (red and pale yellow)
Samsung EVO+ has a 256GB model (red)
Samsung EVO Select has a 256GB model (green)
Other manufacturers also have 256 GB models, e.g. Patriot LX and ADATA Premier
Lexar has 256GB models but I've heard they're ceasing producing storage products

Oh, there's one more thing that I'd like to note: The "maximum supported storage capacity" actually depends on the SoC (chip) and system. So as long as your phone is running on an SoC later than 2015 and Android 5+ (Lollipop) then it should have no problem supporting a 256GB microSD card.

Yep, 18 months makes a big difference :)

Moto X Force is one phone that supports cards up to 2TB.

Expandable Memory
With the option to add up to 2 TB of additional storage space using a microSD card, the Moto X Force offers plenty of room to store your favourite pictures, videos, music and apps.

Original screenshot of the device specs
Though currently, I don't see cards with a capacity of more than 256GB.

Is it possible to get Android 6.0 if you have any Android 5.0 device?
As you may know, Google came out with the new Android 6.0 but it is not available in my country right now. I was wondering if I bought an Android 5.0 device from the store, would I be able to upgrade to Android 6.0 manually in the future?

Without knowing your exact phone's model number, carrier etc. We are unable to tell you if the manufacturer planned to roll out Android 6.0 for this specific device.

Possible duplicate of When will my device get the Android 6.0 update (Marshmallow)?

I'm not sure if you understand how Android works. You can't just throw purr Android 6.0 on any phone. You need the device drivers, then you have to include them into the OS. This is a very technical process that very few people can do. You'll have to find a custom ROM that somebody else made for your phone, or you'll have to hope that your manufacturer released a ROM for your phone.

You need to choose carefully, since many vendors and carriers will abandon devices quickly as they release new ones. So no, you cannot guarantee that ANY device running 5.0 will be able to upgrade to 6.0.  However, here are some suggestions to improve your chances:

Get a recent Google Nexus device. These are always the first to get new releases because they are Google's Android showcase devices. Check this page for devices that have 6.0 firmware available.
Get a device that is on this list. CynaogenMod (CM) is a very good alternative firmware that has breathed life into many, many old
devices that have been long-forgotten by the vendors. CM13 is the
version based on Android 6.0 and they are working hard to expand the
number of devices supported.
Take a look at XDA-Developers device
forums and look for devices that have unofficial Marshmallow
builds. Keep in mind that many of the ROMs posted there are
experimental and possible unstable, and this may be especially true of a new 6.0-based ROM.
Get a device that has an upgrade guarantee or a device that the manufacturer has stated will be getting 6.0. This article is a nice recent list that will get you started, and there is also a Community Wiki on this site tracking status.  However, keep in mind that even if you have a device from this list, the carrier may take longer to (or never) push out the update. As an example, I once had a phone where HTC had released an update but my carrier took almost a year to push their branded version to my phone.  If you can't root your device, you may be at the whim of your carrier.

Not to forget 5. What's really new in Android 6? Is it worth the hassle?

A phone with a WiFi signal icon appears on the status bar (Samsung Galaxy S6, Android 5.1.1)
What does the following icon that looks like a phone with a WiFi signal in my status bar indicate? And how do I remove it?

As far as I know, I didn't turn any setting on that triggered it. I can't find the icon online. My first guess was that it was either VoLTE or VoIP or WiFi calling, but I do not have any of these as options on my phone.
The icon does not go away unless I turn off WiFi. Below are screenshots of my full home screen and of the open notification panel.

The screenshot below is of my phone's "Call Settings". I have no 'Wi-Fi Calling' option. According to guides online, it should come after the 'Vibrate' option. The screenshot below is the results when searching 'Wi-Fi' in settings. No call options come up.

It definitely is the Wi-Fi Calling icon (even though I do not have it as an option on my phone) -- I tested it now and I can phone my contacts when in flight mode.

It looks very close to other WiFi Calling icons, so I'm pretty sure it's WiFi calling.

In short, it indicates that for mobile calls, the WiFi will be used if there's a good WiFi signal.
I have found it there:

Small phone with Wi-Fi coming from it
This strange new symbol shows your phone’s set up for Wi-Fi calling. It’s a new feature brought in by the UK’s biggest networks to help give you the best call quality. If your phone doesn’t have good reception, like when you’re indoors, it’ll make phone calls using an available Wi-Fi network instead.

Thanks :) You are correct. See EDIT 2 and 3 in OP. (I am still baffled how this setting is on though.)

What cell provider do you use? Sounds like they either enabled a feature they had turned off, or updated your phone to add support for wifi calling.

@remnant I think you could do something via the SIM menu - there should be such an app. Also try to open the phone app and check its settings.

Sony Xperia Z1 will not boot up
A month ago, i used Kingroot to root my Sony Xperia Z1 running lollipop . Today, my dad called me on the phone and i picked up. 5 minutes later, the phone will not boot up. I thought that the battery is dead and tried to charge the phone using the original wall plug.
The phone will not charge or boot up. It will show red blinking on my phone. I highly doubt that my phone has no battery at all because it is 40% when i last used it to call my dad.
Also i have tried to power on the phone by pressing the on and power down/up button but it does not work. I have tried to reset the phone by pressing the small red button at the micro sim slot but is also does not work.
I have also tried to use the Sony PC Companion but it does not detect my phone after i have download the installation for the update. I have also tried using Emma but it did not detect my phone at all.
Now what i know is that my warranty is void because i rooted my phone and they are going to charge me to fix it. And before i send it down to repair, i would like to know what else can i do to boot up my phone.
Thank You
Jun Run

Why are my replies to a group text appearing multiple times?
It used to be that when I would reply to a group text, my reply would only show up once. Now all of the sudden when I reply, my reply shows up multiple times. If 5 people are on this group text, my reply shows 5 times. I can't figure out how to stop doing that.

The category "Other" in my Storage takes 4GB out of 6GB on my Internal Storage, any way to clean it?
I have HTC One S. When I open my Storage , it says :
4.10GB/6.07GB ;
Apps: 220MB ; Other : 3.88GB ; Available: 1.97GB .
That's after I restarted my phone on Backup & Reset. I did it several times , and it doesn't change. I'm clueless. I don't have any ideas on what could take that space , nor how do I clean it (properly ofc.). I was looking on the internet for a whole week, and still have found nothing useful. I have tried Clean Master. It doesn't make any difference in the "Other" category. Still the same. It is a old phone , my dad was using it for 1/1.5 years , but I don't think it has any influence on the current memory , after resetting the phone.
Only the "Apps" is clickable in Storage. In other words - I cant click on "Other" to see what's inside. I tried an app called "Disk Usage" , and it says: 1)When I click on app storage : Applications : 220MiB ; Data : 2236MiB ; Free space : 2016MiB .
Now , 2)When I click on Storage card: Storage card: 10171MiB ; System data... Android... (and many more little stuff) ; Free space 10164MiB...
I'm not worried about my phone storage - on storage card. I'm worried about my internal storage , which is, I'm pretty sure , showed on app storage. The big thing : FREAKING 2236MiB FOR DATA? It has to be Data that's messing me up. Data is lost when resetting the phone with erasing al the data , right? I did it several times , but still , the category "Other" still doesn't change at all.
From this , kind of a bigger talk... well to read it is big, right? Never mind...
Again , from this bigger talk , I actually only want to know the answers for two questions : What is on "Other"? and , How do I clean "Other"
Thank you for responding in advance.
https://onedrive.live.com/redir?resid=ABE64B8B54D4B3FA!3407&authkey=!AEzUeDYmxJnRCo8&ithint=folder%2c  (here are the pictures)

Give us the output (screenshots) of Diskinfo

I don't see where/how to put screenshots in a comment.

You can [edit] your question and upload your screenshots there.

I have added the link for the pictures. It should work , and if more pictures are needed , tell me.

@YouLiveOnlyTwice Do you see a sdcard/DCIM/.thumbnails folder? If so, delete it.

Don't see it. Doesn't mean its probably not there , right? Nevermind. Just to mention : I can totally delete anything on my phone. If possible , I want to make it as clean as new. Not much stupid data taking over my internal storage...

It's actually the app data. For example, on my phone I see 184mb for Abbyy (that's dictionaries), and I'm 100% sure those 184 come of the downloaded dictionaries for the app.
To remove the data (I'm not responsible for the lost data in apps, because there will be such):

click on any of the checkboxes before the data chunk name
click select all in the top bar
click the recycle bin in the top bar

I do not see what you mean. I am not really into this stuff. Can you go step by step with me? 1)Open settings ; 2)Apps .... and stuff like that , please

@You What? You know how to go to "other", right? So you go there and apply my steps.

The "Other" is not clickable..

Deleting unwanted package files
I have a samsung galaxy ace, android 2.1, jailbroken. I had 48MB free space and tried to install a 46MB file but it says that the package files are incorrect or smth of the sort and doesn't install.
My problem now is that I have only 2MB free space and I have to locate where these new files are to delete them with root explorer. The play store doesn't seem likely.

Can't find my phone... Really..!
So this is the situation: three days ago I was looking for my galaxy s3 and couldn't find it. It's an extra phone, so don't use it much. So I asked device manager, and it reported it online several days ago, but gave me a location at my address. I sent a ring signal but nowhere was any sound to be heard. The app said "ringing" so it must have communicated with the phone. Since then it reported my phone unavailable and available intermittently.  I have called the phone and it rings silently before switching to the answering machine, so I conclude, that it's on and probably in a charger somewhere. It doesn't run several days without charge, I figure.
Checking all outlets in the house and outside, I can't find a charger plugged in.
I even checked my Google play to see if there might be installed some kind of gps faker. No there isn't.
Also...  six days ago my location history reported the phone to be travelling by train 120 miles away and being there for almost a day before suddenly returning back to my house.
I'm puzzled, to say the least. Are there any tools to help me? Or what might be going on?

To clarify, I can see the exact route the train went including stops, so the phone must have had Internet connection while traveling. Can it perhaps log while offline and then upload the data when online again?

It's still able to locate the device...  Is that a flaw, or might the GPS location be spoofed by someone adding an account and installing apps I can't see on Google play?  I mean..  If it's here, it would be connected to some outlet at this point...

Still gone and still responds to location requests...

Android phone is turned off at 52% battery
I have got a Samsung Galaxy Grand Neo Plus with Android 4.4.4. When the phone reaches the 52%, it turns off and I can't turn on it again because the battery is at 0%!
I think this could help: When I charge it completely, the phone turns off (as I've said, when the battery is at 52%), BUT, when I charge it by... 60%, it pass the 52%.
EDIT
The problem was the battery. The solution was buy a new one.

I would start by  holding all three physical buttons for a full 3 minutes (phone switched off) to fix battery logic problem.  this resets the battery logic on some phones and how the battery talks to the software to let it know how much power it has based on the voltage. After that start the phone (may take some restarts ) and charge the phone
Next, eliminate Battery Problem by changing battery

A) Battery lived it's life. If the battery is removable, borrow a battery if possible and see the behaviour. Check if it is bulged. Easy way for this is to keep the battery on a flat surface and try to spin it. If it "spins", it is due to battery bulging and changing battery is indicated
B) Battery has a chip that provides phone health and condition to device. Based on this information, device takes actions such as stopping the charge, LED notifications to show battery charged etc. Changing battery will also rule out possibility of this chip having gone bad

Fix OS problem. Fuel Guage drivers ( part of software in your device) corrupted. To rule this out, i suggest back up your data and with your recovery wipe clean all Cache and system and flash stock ROM (requires root). If not rooted, try a factory reset (deletes data, so back up before this). Our else if Kies supports reflashing ROM, do that. If the problem continues, it is likely that it is not a driver corruption issue.
Fix Hardware problem of device Hardware of battery charging chip gone bad. Less probability and best handled by service center

Getting to the root of the problem takes time and I would proceed in the order suggested. All the best and do post the conclusion, it may help others having similar problem with your device make

Hi beeshyams, as you have said, I proceeded in the order you have suggested. Trying the first option, I wasn't able to start the phone. Is that normal?

Phone shouldn't start...normal...

Hi beeshyams and thanks! You solved my problem =) The trouble was the battery. I went to buy a new one yesterday and the problem was gone! Thank you very much (I'm gonna edit the question to write the solution)

Glad to hear that and that I could help

If you "buy" an app in the Amazon Underground, and it is later removed from the Underground, do you get to keep it?
If you aren't familiar, the Amazon Underground offers a bunch of apps for free (including IAPs).  The downsides are user tracking, pop-over ads, and the possibility of the app not working if there is no internet connection.
Once a person "buys" an app in the Amazon Underground, it is listed in the associated Amazon account.  (I put "buys" in parenthesis because there is no charge.)
If the app is later removed from the Amazon Underground, does the "buyer" get to keep it?

I'm bit unclear here. Are you asking: If an app is removed from Amazon Underground, would its users lose the app automatically (removal triggers whenever Android sync with Amazon's server) OR is it legal for users to keep such an app after Amazon has it removed from Underground? The latter would be considered off-topic (we don't deal with legal questions. Visit [help/on-topic] for more info). However, this may help you a bit: https://developer.amazon.com/public/support/legal/da#AmazonUndergroundSchedule (see "6. Withdrawal from Amazon Underground.")

@Firelord I am just interested in the former (would users lose the app automatically).  I didn't even think of the legal side, as I would assume Amazon would immediately remove the app if there are any legal issues.  Regardless, as you mentioned, that is off-topic on this site, so we can't discuss it.

@Firelord The answer is partially in the latter link you provided: "[Amazon] may continue to provide existing end users with access to all Amazon Underground Apps they purchased through Amazon Underground, along with any In-App Products they purchased through those Amazon Underground Apps, after those Amazon Underground Apps cease to be available for purchase through Amazon Underground."  What that doesn't say is whether or not they typically perform that action.  Perhaps others know from experience.

Where is the backup location from Titanium Backup on a phone without an SD card?
I am currently using a Samsung S6. Today I backed up all of my data with the app "Titanum Backup". After backing up all of the data, I transferred the folder of Titanium Backup to my Google Drive. Afterwards, I restored my phone. Then I installed Titanium Backup. However, I don't know where I need to import the folder "Titanium Backup" for the app to restore the the data. I saw many YouTube videos, and their restore was in a SD Card. However, the S6 doesn't have an SD card. Can someone please help me? Thanks.

You can put it on the internal SD card as well (e.g. /sdcard/TitaniumBackup). At its first start, TiBu will ask you to chose a location.

s6 don't have an  sd Card. So what should i do?

It hasn't even an internal SD card? So where does it store photos etc? Hard to believe ;)

@LouisRuan, try to understand: if your device doesn't have an external SD card, then the location /sdcard will point to internal SD card (it comes with all phones and S6 is no exception). Just make sure to download the folder from Drive and put it in the heart of /sdcard/. Use a file manager such as ES File Explorer. If TiBu doesn't detect the folder, go to its settings and choose the folder manually. Then reboot optionally.

For you it may be 'internal shared storage' or 'main storage' or similar name. Check with whatever file explorer app you have. And also you can always change the location of backups from within tb setting 'storage preferences'.

Battery Stats Are Vastly Incorrect
After updating to 6.0.1 (MMB29K) from 6.0.0 (MRA58R) I have come to face a very odd and never seen before issue. My battery stats are wildly wrong. My stats show 4k% or higher and no battery stat monitor, such as the system battery monitor or GSAM for example can see anything correctly.
Here is an image of what the battery stat shows:

Here is the power manager:

Has anyone encountered this issue and if so what's causing this? I have not found anything so far that would explain it. Although I have not yet had a chance to fully comb the source code of the latest release, I don't suspect they would release it with such a glaring issue, so I am wondering how it has come to be.
Some FYI, Its a Nexus 6 device, fully rooted and not that its relevant but also fully encrypted. Anything else you wish to know, let me know. The apps and configurations have been the same on this device (+/- occasional test app that is usually removed within a day or so) since its stock 5.0 OS (which was unlocked and rooted immediately upon receipt).
UPDATE: 12/20/15
I want to begin with many thanks to @beeshyams to offering assistance and providing possibilities to consider. Although the problem was not entirely covered by our discussion, I did figure out what the issue was because of the decision we made to reflash the boot.img and that revealed the problem. Short version, reflashed the stock 6.0.1 boot.img and it resolved the issue. Long version, read below:
TL/DR/RL
The systemless method by which the boot is being done beginning with M (6.0) was to use the SuperSU zip update to root the system without actually modifying the system partition, making for a potentially cleaner or if you will less hacky way of getting root than in the past using the system exploit. Feel free to follow the process by @chainfire here: [WIP][2015.12.20] Android 6.0 Marshmallow [v2.64] but simply put it would use a modified boot.img and a special version of the SuperSU and achieve the root. However as the project gained momentum and new methodology was tested, it was decided in favor of abandoning the use of the modified boot.img and allowing the improved SuperSU binary to handle the internally required modifications. I had forgotten to change the batch file I use to automate the process to remove the patching of the modified boot on top of the stock boot and that's in simplified term what caused the issue. I reverted the boot to the stock and applied the SuperSu binary again to modify the stock properly and it fixed the issue. Thank you for everyone's attention and I hope that this will help others in some way.

I would start by holding all three physical buttons for a full 3 minutes (phone switched off) to fix battery logic problem. This resets the battery logic on some phones and how the battery talks to the software to let it know how much power it has and other parameters. Service center may be able to help you with exact procedure for your phone (please share their recommendation so that can help others)
Few possibilities if above didn't help:

Battery houses the chip that communicates state of battery to device including charge levels, temperature etc. That could be bad, though your phone is new, being a defective piece. Can be checked by replacing battery
Fuel Gauge drivers in OS corrupted. After backing up data,reflash stock to rule out this possibility. Also eliminates rogue app possibility, though app mischief not likely on your case
Problem with hardware (Fuel Gauge chip). Unlikely but possible

Edit
Further to our discussion, saw this on Nexus forum, which sends to have worked for most, though none reported your problem https://productforums.google.com/forum/m/#!topic/nexus/D7er7nMbzHI

1.Power off your phone.
  2"Press and hold the Power and Volume Down buttons. This will put the phone in fastboot.
  3.Use the Volume buttons to scroll through the menu until you see "Bootloader logs"
  4.Press and hold the power key for a long time (7+ seconds) until the phone reboots.

3 button procedure described in my answer as first option is more elaborately covered here http://forums.androidcentral.com/verizon-htc-one/394469-battery-charger-reset-procedure-htc-one-m7-m8.html
Let me know which works...

Thank you for the suggestions. #2 this is a fresh flash of the new ROM image, so that takes care of that, hence my surprise. #1, #3, not saying not possible but to have it happen immediately after the update only, that seems a bit too coincidental of a timing, no? I will try the 3 button reset, I need to figure out how to do it so the device stops turning on :)

Thank you for the extra information, I appreciate that. I am sorry for the delay reporting back, I have been engaged in trying a number of things. I rolled back to the previous version and sure enough the problem disappeared but imaged back to the new one and BAM its back. I have tried several of the solutions and so far no luck. The fastboot reset method did nothing, I used terminal to remove the batterystats.bin (a shot in the dark really) but to no avail, I have tried just about everything, this is very very puzzling.

I know, the deleting of batterstats.bin as I said was just a shot in the dark, not something I considered a real solution but when you have no solution present, you try what is harmless just to cover all the bases :)

Ok I understand. Just to be clear, you want me to only roll back the boot.image right? To test the theory we are referring to? If I understand correct and please correct me if I haven't, I will use the previous boot image along with the new system image? Is that the combination you mean? Because you are right, something is going screwy somewhere and given the roll back "fixes" the issue, it has to be something in the new image, I will reach out to the developer team too and see if they know what's up. I am waiting to hear back but maybe I need to poke a bit more.

Will do, thank you, I will keep you posted, give me through tonight and possibly part of this weekend to get it done and provide feedback, I am juggling a few things right now, so I don't want you to think I abandoned it, I stick until its done.

I resolved the issue, and many thanks for your support on this. I have updated the post to include the details of how and you are welcome to add whatever you feel is necessary. Again thank you and hope you have/had a good weekend.

Appreciate it, thank you. I also DID upvote :)

Please add more details in the question to get a detailed solution. Screenshot would help. most recent changes you performed on the device? Rooted? Custom Rom? What have you tried so far ?

I used my tablet for about 4months, before i encountered this problem. I tried reseting my tablet to factory settings but that didn't help. I did  out of the orginary to it other than download Google play apps.

Problem - when I try to turn on WiFi or blue tooth the switches stay in turned off and gray.

Considering that your question is completely vague, I'm taking a total guess:
Turn Airplane Mode off.

Is it possible to install Stock Android?
I have a Lenovo K3 Note and it comes with Android Lollipop with some custom skin and apps from Lenovo. The problem is, in spite of having a decent hardware, the phone lags too much.
I was wondering if installing Stock Android would somehow make it better. So can I get stock Android image and can I format my phone with it?

Possible duplicate of What is involved in installing Android onto a device?

For you, whatever the manufacturer, i.e., Lenovo, provides on-device is the "stock" Android. In case you mean AOSP, or "pure" Android, that is a different question altogether.

This page has a list of custom ROMS (some based on the stock ROM) for your phone.
Since each phone has a different hardware configuration, stock Android has to be modified to suit each phone's requirements. So Google's ROM will not work directly on your device; someone will have had to mod it themselves, and such ROMs may have other issues. Some custom ROMs have been tweaked to have even better performance than stock Android, so keep that in mind.
If you want to minimize the chances of having other problems (connectivity issues, battery issues et cetera) on your phone, your best choice is to research more on each ROM, and flash one made by an experienced dev.
You can Google the ROM + your phone name and find out more about each ROM and how well it works on your phone.
Please note that stock ROM, refers to the ROM your phone came with, and not Stock Android.
If you don't find any stock ROMs to your liking, consider flashing a well known ROM, like CyanogenMod on your phone.
Here is a tutorial on flashing CyanogenMod on your phone.
Read the video description first to install the ClockWorkMod ROM manager first.
Flashing any ROM on your phone voids your warranty, and may cause your phone to have more problems than you did on your phone's original ROM. Keep that in mind before you do any of this.

You just said it all!! D:

What specifically prevents OTAs from being taken on modified /systems, and why can't it be shut off?
I have had a constant nightmare with not being able to take OTAs on any of my (rooted) devices. They boot into TWRP, complain about the build fingerprint, and won't install, so I have to wait for a full .zip and flash my systems manually.
What is it that is preventing the OTAs from installing over a modified /system partition, and why can't it be defeated or disabled?
If it can't be defeated/disabled, why can't my modified /system lie about its build fingerprint to fool this validation into allowing the OTAs to be installed?

OTA files work by patching files rather than replacing them will a full copy of the new version of the file. This means that it has to verify that the existing files are exactly as it expects or the patching process won't work (or could cause the file to become corrupt). If you were to fake the fingerprint and force the OTA to apply you might end up with a device that can't boot due to some files being corrupt.
Android 5.0 (i think) switched from verifying just the files it was patching to verifying the partition as a whole so any modification (even to a file that is not being patched) will cause this to fail.

Do you have any idea why can't this be removed or defeated?

Oh, I see - you're saying the contents of the OTAs now are based off the unmodified system, hmm. In that case I'm just confused on what could be so 'different' on a /system that had been rooted, and then 'Full Unroot'ed.

Hi, so you think OTA's are performing dmverity-like checks now ?

@moonbutt74, it appears so. I think it is because of that removing alien files from /system during unrooting doesn't work to fool a system update because the arrangement of bits in a block before rooting and after un-rooting would certainly differ.

In addition to answer posted by @bmdixon

OEMs like Samsung have Knox counter which gets tripped once you root or replace stock recovery by custom. There were work around earlier to this, but Note 4 onwards tripping Knox "burns" this information into the hardware. Only way to revert Knox status is  by changing that chip on the motherboard !!(I am not aware how  this is achieved but it is on record as a mail reply from Samsung ). I expect OTA to verify this first
OEMs like Huawei (my current device is Honor 6), allow you to unlock boot loader and cover it by warranty allowing OTA updates if rooted but stock recovery intact. Replacing recovery fails OTA
I suspect carriers which "lock-in" their customers will also employ their own means to verify before allowing OTA (probably this is one reason why there is a varying delay in carriers rolling out OTA)

So it may not be a simple solution to have the recovery trick OTA...too many tricks to learn and proprietary ones, which is NOT the purpose of TWRP

How to view bargain sales on Play Store ordered by discount or category
Before this is marked as duplicate, here are related questions but NOT dealing with this question

Is there a way to sort apps in Google's app store by size?

Is there a way to sort apps by popularity (number of 'downloads') in the Google Play Store, or otherwise?

I prefer to manually update play store apps periodically. Yesterday, while doing this, I found a couple of apps which were purchased about a year ago at steep discounts, in one case a $9 app is now priced at $5 and in another $2 app priced at 20 cents.
This set me searching for more discounted apps on Play Store, which are not listed separately as discounted but included in "Top Paid". Further, there is no way of filtering discounted apps, or by discount percentage
Couldn't locate any app to do this and further search led me to this What are the alternative Android app markets? to see if any other app could do this.
Appbrain App Store seemed most promising and it delivered better results, but partly. It shows discounted apps separately when you filter by Price Reduced, (which is a huge improvement on PS) and assigns rankings (not related to discounts). But it doesn't give filtering choices to go by "categories" or "discount amounts", which means if I am looking for a key board app bargain as an example, I still have to trawl through all screens manually or if I am bargain hunting and want to buy an app based on discount compared to original price, I can't
Question
Is there a way to view discounted apps by discount percentage or category in either Google Play Store or in alternative app markets and  preferrably  purchase through existing credentials on Play Store?

How log logcat in a bootloop?
I have a Pipo X8 device, and I want to log logcat output because it gets stuck in a bootloop when I try to install Xposed framework.
The problem is that there is no USB, thus no USB-debugging, and Ethernet hasn't got time to start up before bootloop restarts. Hence, I can't trigger the logcat command. How can I log? Can I do a script that runs att startup and logs to file? How would i make such a script?
I believe making an app with BootBroadcastReceiver is far too late in the startup chain.

Do you have a custom recovery installed? What do you mean there is no USB? Does the device not have a USB port?

I don't have any USB host ports no. No I don't have custom recovery. I have root however.  Can custom recovery like Clockworkmod log through a bootloop?

Can't boot Samsung galaxy ace GT-S5830i Failed to mount /system (Invalid argument)
I can't boot my Samsung galaxy ace GT-S5830I after I tried to flash a custom rom built for the GT-S5830, if I try and boot into Recovery I get the following errors:

I have tried flashing using Odin and flashing again from the SD card using a different rom but that didn't work! Is there any way to fix this?

There is a way to fix this. You have to sideload that ROM. For that -->

Just download adb (android debug bridge) minimum requirements. Sideload  your rom . It may seem to you that you got stuck there but don’t panic, wait at least 5 minutes. After that remove your battery and press (Power+Home+volume up) upto it shows samsung screen and then release. Then just install your rom from recovery mode.
No need to get panic on those failings. They happen sometime.

Block Google app on Lollipop 5.1
My son had an old Moto G running KitKat. On that phone, I set up an app locker to block the Google app because there was no way to restrict the "safe image search" on that app. Instead of him potentially being exposed to explicit images, I just blocked the app entirely.
That phone broke last week, and I just bought him the new Moto G (2015). Evidently, in Lollipop, you cannot block the Google search app using an app blocker. Accordingly, there is no way to keep my son from searching for and finding explicit images using the Google search app.
I have searched the internet for a solution, but cannot find one. Does anyone know whether there is any way to block the Google search app on Lollipop?

Welcome to the Android Enthusiasts! Maybe using a restricted profile is an option?

There are multiple solutions which can be used here.
Disable or hide the app
If the device supports multi-user setup, you can can create a secondary user account for your son and put as much restrictions you want.
If you don't see Users under Settings app, your device officially doesn't support  multi-user setup. See a bypass here: Multi-user option not avilable in Android one after Lollipop update
Anyhow,

Setup adb in PC, enable usb-debugging in device and plug the device into PC.
Create a new user from Settings -> Users and switch to it.
Go to Settings → Apps → All apps → find your app, tap and disable it.

If you think disabling may not be enough, simply make the app inaccessible to your son. Follow these steps:

We need to know the UserID of the secondary user we created. For that follow my answer at How to find out currently running user name/ID from ADB?. The UserID most likely would be 10.
We're going to hide any app whose usage you find questionable for your son. Execute
adb shell pm hide --user UserID PACKAGE
Replace UserId with current user ID you found and PACKAGE with package name of the app. For Google search app, it is com.google.android.googlequicksearchbox.
Hiding here is akin to temporary removal of app, with the major difference that app is never removed from the system but only inaccessible to current user. You can always unhide the app by replacing hide with unhide in the said command.

You may be able to skip some steps by using Debloater app

Rely on automation
I'm not sure how your app blocker app really works. It should have no problem. Anyhow, you can use an automation app, such as Tasker to block usage of an app.

Profile: Applications → choose app(s)
Task : (Actions): you have range of options to choose.

You can send the kid back to home screen whenever app is launched.
Action: App → Go Home
You can launch another app as an alternative.
Action: App → Launch App
You can create a transparent scene with dimensions equivalent to screen and use it in overlay blocking mode. This would make screen not receive any input hence app would become useless for your son.
Action: Scene → Show Scene
Disable the scene whenever the app is closed or some app takes over, using an exit task.
Action: Scene → Destroy Scene
See my answer for more info at How to add screen filter with tasker?
If the Android is rooted:

you can force-stop your app
Action: App → Kill App
you can implement previous section for your only user in order to hide or disable the app on-the-fly without the need of PC. You just would need a suitable trigger

Note: some of the actions mentioned for Tasker can be achieved using MacroDroid, AutoMagic, Automate and AutomateIt individually.

WinSCP for android
Is it possible to transfer files to my Fire Tv Stick with the ES FILE EXPLORER.
Is it necessary to root my fire tv stick first?
This is not possible with fire tv stick because you cant enable root explorer

What do you need root for there? ES has built-in support for network access, so you can use it to download files via FTP, SCP, even SMB (Windows shares). Assuming ES is installed on that Fire stick, which you don't say.

ah so if you have ES install on your fire stick you can transfer files with the FTP, SCP with out rooting your fire stick?

Sure. You can use ES to browse remote resources and download from/upload to those.

Anytime! I've summed it up in an answer for you. If that solved your issue, please tick the check-mark next to it so it's shown as working solution. Enjoy!

As you already use ES File Explorer on your Fire Tv Stick, you can use that directly to access network resources. The app supports multiple protocols, a.o. FTP, SCP and SMB – but also cloud resources such as Dropbox and SkyDrive.

ES File Explorer: LAN access (source: CNET; click images for larger variants)
Once set up, you can use that to browse remote resources, and exchange files with them.

Creating viber account on tablet
So I get myself android tablet last nite and wanted to create viber account.  I put my cell phone number down,  and never received code on my phone. I still have flip phone, not smart phone. Could that be reason? I would be very interested in this product and I would appreciate if someone could help me.
Another question would be is it possible to create viber account without phone number?
Thanks in advance

Where is stored type lock (if users have to enter a password/SIMM or a pattern)?
I'm working on source code of Lollipop. It seems the type lock (if users have to enter a password/SIMM or a pattern) is stored in a database, /data/system/locksettings.db. This database is located in /data but /data is encrypted before the user types the password. So I think it may be stored in another place.
In CryptKeeperConfirm.java, there is this comment:
  /* WARNING - nasty hack!
               Settings for the lock screen are not available to the crypto
               screen (CryptKeeper) at boot. We duplicate the ones that
               CryptKeeper needs to the crypto key/value store when they are
               modified (see LockPatternUtils).
               However, prior to encryption, the crypto key/value store is not
               persisted across reboots, thus modified settings are lost to
               CryptKeeper.
               In order to make sure CryptKeeper had the correct settings after
               first encrypting, we thus need to rewrite them, which ensures the
               crypto key/value store is up to date. On encryption, this store
               is then persisted, and the settings will be there on future
               reboots.
             */

That leads me to believe that the settings for lock screen (including type lock) are stored in 2 places. Does anyone know what other places lock screen settings and type lock may be stored?

In the same directory or if there is multi-user setup, go to /data/system/users/USER_ID/ look for .key, such as password.key, gesture.key files. They are the keepers of secret. See source. Also, /data already is decrypted once you reaches the lock screen.

@Firelord Thanks for your comment, but i'm talking about type lock and not password or pattern. I edited my question. I know passwords can be stored in data even if its encrypted because the system will encrypt the password entered by user at lock screen then compare it with the encrypted password. But how the system know what lock screen it should propose to users if data are encrypted and user have to enter is password/pattern to decrypt them ?

Can 4G be used on a 3G phone if 4G bands are supported?
I have a 3G phone but it supports the 4G band (1800 MHz) which is available in my area. Is there any way I can enable my phone to support 4G?
I went to *#*#4636#*#*, and there is an LTE option, but I cannot select it. Each time I select it, the option changes to WCDMA Only or WCDMA Preferred.

Is your phone called the Micromax a350 Canvas Knight? If so, I'm sorry, but your phone DOESN'T support 4G, according to the specs sheet found on gsmarena.
Don't be excited to see the LTE in the *#*#4636#*#* options, because that menu lists all the possible bands there is, although your phone might not support all or some of them.
The maximum you can connect to is 3G, you therefore can't use the 4G in your area. The limitation is not software-related. It is hardware-related. The hardware component responsible for supporting 4G band isn't in your phone.

Rooting issue on my xperia m
I have got my Xperia M and somehow now it says "Type password to decrypt storage." I have tried all ways but nothing has helped. Will rooting the phone help my cause? Will it remove the encryption?

There is a lot of information about this out there, so I suggest you try searching first and then come back if you are still stuck. This search should get you started.
Unfortunately, I think you're going to have to factory reset the device, which means you will lose your data and installed apps. I really don't think rooting is going to help you since that will not give you the needed decryption key in itself.
Hopefully you have a backup. Good luck.

I have already tried factory reset opton,but its of no use.. What more can i do?

Any one found solution?

Why am I not able to select VLC player from inside the BubbleUPnP app?
I noticed after the updated of my Nexus 7 from Android 5 to 6.0.1, that my DLNA app BubbleUPnP (Version 2.5.5.1) stopped detecting video players. I am trying to view a video from my library with VLC Player Version 1.7.2., but I just cannot select it. Before with Android 5, the player could be selected, but I don't know for sure, if it changed because of updating android or the app. I also tried another player. Not selectable, either. From within other apps, e.g. Total Commander, I can select every intalled video player.
I have an other device, too, with Android 4.3. BubbleUPnP and VLC are the same versions and there it all works fine.
I already asked the bubblesoft support, but unfortunately they don't have an idea, either... They claim that they tried it on a Nexus 5 running the same Android and app versions, and everything works fine.
How can I fix it?

You've tried reinstalling all the apps involved? Or check the play store if there are updates for the apps involved.

Yes, reinstalled both apps. Always most recent versions

Marshmallow has reimplemented the Android "Share" menu, maybe your DLNA app has not yet been updated to use it properly?

@TamoghnaChowdhury The support claims it was tested on a Nexus 5 running the same Android and App versions, and it worked well. How would you explain this?

If the issue is not fixed yet, try installing "App Picker Classic" and click on Clear defaults in the app menu. It should fix the issue. At least It worked for me.
A

Perfect! Installed, clicked, removed again and then I could select VLC in BubbleUPnP. Thank you very much!

Make Hangout ring rather than the phone ring for incoming calls
I have a lousy mobile service with weak signals. When I use wifi, I want to use Google Hangout to receive incoming calls.
I have associated the phone's number with my Google Voice number.

At first, I forwarded incoming calls to my GV to my phone (by checking the box before my associated phone number in GV settings), but then my phone's Phone app always hijack the incoming calls (I don't know if that is because I set up something on my phone), and I can't answer the calls using Hangout.
Then I stopped forwarding incoming calls to my GV to my phone (by unchecking the box before my phone number in GV settings), but then Hangout doesn't ring for incoming calls.

My phone is Kyocera Hydro Icon with Android 4.4.2.

Do data-only SIM cards have a phone number assigned to them?
Some providers offer a "data only" sim card. Do these types of sim cards have a phone number assigned to them? If yes, what happens if a dial out is attempted of if there's an incoming call?

A number has to be assigned so that the (rather old) system can recognise the SIM.
Just because it has a number though doesn't mean that any calls can be made or received and will already have been disabled by the network.
The provider can add services as wanted/needed though: SMS can be useful for managing routers.

in my country data-only SIMs can send and receive SMSes. Some provider even allows a normal sim to be converted to a data SIM

Indeed it's up to the provider what they want to provide.

Usually, they have. Usually, "data-only SIM" only have a special tariff plan with cheap data service rates, and is an ordinary SIM from all other points of view.
Finally, it fully depends on cellular provider - it can allow voice services, or it can prohibit them.
So, the only way to get a correct answer is to try.

Yes, they do have number, perhaps, special number, taken from a specialized pool of numbers, allocated for certain purposes, such as assigning tailored tariff plan to them.
You might hear of "Numberless" sim cards in some parts of the world, however, these sim cards aren't entirely numberless. You'll need a number to actually use it.

App as Lock Screen? -OR- Allow app to run when device is locked?
I've got an old android device running CM11 (KitKat) that I'm using mainly as an alarm clock.
I'd like to be able to run only the clock app (Gentle Alarm) .... and then if I want to use any other apps like email or whatever, I'd have to unlock the device.
A lock screen widget doesn't quite cut it, as I'd like the full functionality of the alarm clock app (or actually, any app I select, for that matter) available, but as soon as I click the home or back button, I'd be taken to my lock screen.
I could see this feature being useful for lots of reasons... say if I had a tablet as a remote control for the TV/stereo that guests could use, yet i didn't want them running other games or apps.
Is this possible?
I'd be willing to consider other ROMs if that's what it takes.

Which device is it? Can it be upgraded to any Lollipop version, because Lollipop can screen pin an app i.e. you would only be able to use a particular app nothing else? Otherwise, see if ProtectedApps helps. Run it on all the apps except AlarmClock and whenever other apps would be activated a lockscreen would show up, be it custom or native. // You can also use any "app locker" app from Play Store. // You can also use an [tag:automation] app to lock the screen whenever any app other than clock gets active on screen.

This particular device is a Samsung Galaxy S III, which should support CM 12.1 (Lollipop) per this info. I am not familiar with the "pin an app" feature so I will look into it- may be exactly what I need. ProtectedApps is an option too, but it needs an additional framework and some config and a donation. I'm of the mind that simpler is better, so will hope the pinned app solution does the trick!

Donation is optional (it is only meant to support development of the app). Here is Play Store link for free version: https://play.google.com/store/apps/details?id=de.defim.apk.protectedapps and all it needs is a framework which can be installed just like any app. Download the APK here: http://repo.xposed.info/module/de.robv.android.xposed.installer

Ah, the pinning of the app was exactly what I was looking for. If you'll post your response I'll mark it as the answer. Thanks for the help!

Kiosk mode at your service
What you need is a solution that can put your app in kiosk-mode. There are many apps in Play Store that can do this job for you. Simply search kiosk in Play Store. I believe that some of the apps providing child protection would more or less fit your need too. In that case, Izzy's list on app-locker should help.
Anyhow, I tested four apps that should help you  without requiring flashing any ROM:
clyd Kiosk Standalone Lockdown
It is free/paid app. Free version restricts you to a maximum of two apps. Once the app is closed you'd be shown an interface with selected apps' icons and that is all. You can only launch those apps and nothing more. You cannot access Status bar either. You'd easily know how to exit this once you start using it.
MobiLock Kiosk Lockdown
It is a free/paid app. Free version does the job for us. I didn't test it beyond two apps so I do not know its restrictions, if any. Its usage and behavior is similar to aforesaid app. It's also easy to exit.
SureLock Kiosk Lockdown
It is a free app with in-app purchases. Free version should suffice your needs. It explicitly has Single-application mode and Multiple-application mode. The latter behaves in a manner similar to aforesaid apps and the app can be exit very easily. However, Single-application mode isn't very elegant. The traditional way of launching password prompt didn't work and hence, I had to force-close the app using adb.
Make sure you test this app in Single-application mode only when you've adb setup in PC and usb-debugging enabled and authorized in the device.
KioWare for Android Kiosk App
It is a free/paid app. I believe free version should be enough. Although I saw the documentation, I couldn't figure out why the app always expects that I want to visit a website and hence expect a browser. I couldn't make it work in Multi-application mode at all. Single-application mode worked but I didn't see a way to exit. Again, adb came for rescue.
Make sure you test this app only when you've adb setup in PC and usb-debugging enabled and authorized in the device.
It is very much possible that I didn't understand the usage of or couldn't satisfactorily use this app. Feel free to let me know in comments its correct usage.

Screen pin the app
If you can switch to, or are, already running a Lollipop ROM then you can use screen pinning. On Pin and unpin screens, Google has noted

You can use screen pinning to keep an app's screen in view until you unpin it. For example, you could pin a game so that you don't accidentally exit the game while you're playing. Then, when you're done with the app, you can unpin the screen to get back to the rest of your apps.

Read through the link to know how to pin or unpin an app or go to Settings → Security → Screen Pinning and read the instructions for its usage.
Know that you can easily unpin an app, more easily because Android directs you to unpin it using a toast, should you press a navigational key.
A simpler solution, only for rooted Android devices, is to block such toasts from showing up. Through jan's answer here I found EnhancedToast1 and UnToaster2 app very useful (individually) to block particular toasts. Since they are Xposed modules, you would need Xposed Framework appropriate4 for your Android version.

Lockscreen on-demand
On a rooted Android, you can try ProtectedApps3 app. Use ProtectedApps to protect your launcher app. Now whenever you would press the Home key or go back to a previous app (it must be protected too) you would see default or your custom lock screen. The app would show you its know-how at first run.

Ever-ready Tasker
You want to get your hands more dirty on a rooted Android, use Tasker, AutoInput and optionally, Xposed Additions.
Run Tasker in application context and choose your Alarm or alternative app(s) as trigger. Configure Xposed Additions to disable Home button globally or use AutoInput in a Tasker's task to do that. You can also use AutoInput to disable Back button specifically when you're at main activity of your app.
Follow my answer at Is there any way to disable/enable the back button? to know relevant usage of AutoInput and Xposed Additions, if required.

A tablet with Kitkat
If you happen to have a tablet with Android KitKat, this answer by user77535 may prove to be helpful. (I don't have a tablet so I can't verify it.)
It says, inside Settings → Users, you can create a Restricted profile which would more or less be an app locker to you. The profile however enables system apps and Settings app can't be restricted. It further adds that Xposed module Restrict Me can take care of Settings app here.

1: XDA: EnhancedToast
2: XDA: UnToaster
3: XDA: ProtectedApps
4: Xposed Framework: Android 4.x, Android 5.x and 6.x

Simply outstanding response, thanks for the excellent above-and-beyond  info, Firelord!

Safely buy a used mobile
Is there any step I need to take after buying a used Android phone from a stranger?
Is restoring the device to defaults enough?
The hardware should be fine; I'm talking more about the OS itself and software issues (viruses and so on)

Completely wipe the phone and flash a stock ROM. That's as far as you need to go. Everything should then be back to the original state, right after you would have bought it in a store.

Yeah, but before buying the device, do search on web to be certain that tools exist, can be downloaded and would work on your device to wipe the slate clean and flash a ROM , otherwise you would have a device and nothing to do other than factory reset.

How to view a plain text file created in Linux in Drive app?
I created a small plain text file (in utf-8 encoding) in Ubuntu and then uploaded to Drive.In my Android phone, I open Drive app, and want to view the text file, but it says "No preview available" and asks me to download it. How can I preview the text file without downloading it?

Have you tried uploading a file with .txt extension and preview it in Drive app? Drive may be geared to preview files based on extension and not on mime-type.

In Drive, I added ".txt" to the file name, but it is still not previewable.

Adding a new account to Gmail/Youtube shows a Password Error
I recently goy myself a Moto G3, that is running Android 5.1.1.
I have 3 e-mail addresses, all of those I wish to keep in my Gmail app (I did that in an older phone I had), so I go to "Add Account" in the Gmail app, click "New Account" and...
I'm taken to a "Confirm your Password" screen. And there, I type my password... Only to see a "try again" prompt. And no matter how many attempts I do, all I see is a "try again" prompt. My research led me to know that a "2 step verification" can be the issue, but turns out it's deactivated on ALL 3 OF MY ACCOUNTS!
I also can't add other accounts to my Youtube app, which I need since I need to publish videos while away from my PC. Here's an image of that confirm your password screen. If anyone has any suggestions, I'll be thankfull (just a warning: I'm a noob, so I'd appreciate "simpler" language if possible).
Also, if it helps, the main account is my personal e-mail. I'd like to add 2 "workplace" e-mails to the Gmail app, and one of those is linked to a Youtube Account.

Click on it for larger version

For some reason, updating to Android 6.0 has corrected the issue.

At least for me, it was actually the device password - used to unlock the phone. So basically it asks for the device password when you try to add a new Google account for some reason. I formatted my phone thinking something else was the issue - but if you enter the device password, it then asks for the account name as normal.

This answer works.

Perhaps its a typo, but you say:

...so I go to "Add Account" in the Gmail app, click "New Account" and...

Why do you go to "New Account" if you already have 3 email address?
This is how on my 5.1.1, Adding an account works:

I go to Settings > Accounts > Add Account > Google > 'Enter email' > 'Enter password' > Logs me in

The steps you're describing isn't available, as you only need to confirm your password when creating a New Account, and not when logging into an already created account.
If you see "Confirm Password", then you're not logging in, but rather, creating an account, in this case, a 4th Google account.

I followed your steps and where you said that you had to "enter e-mail" it just showed confirm your password (the image I uploaded) and the issue happens again

Although if I click on personal (IMAP) it does let me enter my email. I assume that wouldn't work with the YouTube app since I don't see an option to add a YouTube account...

How do I recover lost data on a damaged SD card that was encrypted by my tablet?
I encrypted my 64 GB SD card using my Samsung Galaxy tab 3. I don't know what happened to my SD card but when I turn on the tablet, instead of allowing me to use the card, I get the following messages...  >preparing SD card - checking for errors  >SD card encryption - encrypting SD card  >SD card safe to remove - you can safely remove SD card. Any idea what"s wrong and how to fix?

That's why you should not encrypt anything unless its extremely private. Its on every system there if anything goes wrong you loose all the valuable data.

Okay, your issue sounds weird. Your SD Card is 1) Damaged and 2) Encrypted, yet you want to recover data from it?
If 1) is true, then whether 2) or not, you can't access the card. If 1) is false, and 2) is true, then, generally, you should be prompted to enter a password to use in decrypting the card. If that prompt doesn't come up, then you likely might need to use the exact device used in encrypting the SD card to decrypt. If that device isn't available, you might need a similar one to use to try.

Realistic preparations to be made beforehand to locate the device and/or ascertain identity of its holder?
What can and should be done beforehand as a precautionary measure to locate the device or ascertain the identity of its holder, should a person unknowingly lose his/her device for any reason?
I am thinking of ways which provides features, such as:

keeping camera turned on nonstop upload data as much as possible to possibly capture holder's face and location along the way, or
perhaps prevent the phone from being turned off and create a loud sound "THIEFS" in the middle of crowded bus

If the solutions requires app, I would prefer such apps which can't be turned off.
Also, perhaps something we can put on our keychain that will cry out loud if the distance between the Android device and the keychain is above 1 meter.

I changed the question

I found one good solution. Cobra Tag. But it's not available anymore.

Hi! Your edit was still focused towards explicitly demand of apps to achieve objective. As you've witnessed based on closure reason, anything that asks us to look for apps or device is off-topic here. But note that if the problem does require an app you would get it as an answer. Just make sure you don't directly mention your demand for an app or so in question since direct demands causes quite a SPAM here. They also make the question obsolete a bit more quickly. // I've edited and tried to make it as much on-topic I can. I can't guarantee though that it won't be considered too-broad now.

It appears that we already have a question along the same lines: How to prepare myself & smartphone/tablet in the event it goes missing or is stolen?

Default USB MTP for Android 6.0
I would like to have MTP selected by default (instead of charging) when I plug an Android 6.0.x device to a PC through a USB cable. What should I add or modify in the build.prop file of my rooted device to make this happen? I know that it's not possible to do that without root access but the device is rooted.

It doesn't work. The persist.sys.usb.config is already mtp,adb when plugging a USB cable and the "Charging" option is selected by default.

Do you have Xposed Framework installed? If yes, then this module may work for you. (Source). Alternatively, see if this works: How do we toggle on MTP more easily on a Debug-Enabled Android 6.0 device?

The best I found so far is an application named MTPEnabler: http://forum.xda-developers.com/android/apps-games/app-mtp-enbaler-t3263467

Google changed the USB protocol for Marshmallow to always default to charge.
The reason for this change because they brought back the ability to make external storage (SD card) become internal storage. Creating a new storage type called "Adoptable Storage".
Originally google removed the ability to swap storages because they viewed it as a huge security vulnerability.
Adoptable storage
In order to achieve your end goal it looks like you might have to compile marshmallow from source. Find the MtpService.java and then with updateDisabledStateLocked() change mMtpDisabled to false.
MtpService.java

Though your answer clearly answers the question (that requested functionality is not possible to achieve) I still don't understand what is the relation between using external storage as internal storage and default mode for USB connection. What SD card has to do with USB port?

Through Developers Options it was possible in my phone.
Just goto
 Developer option > USB configuration

By default its set to Charging.
Change it to MTP. Try connecting USB, this should work.

Have you tried it? It doesn't work, we only wish it was that simple...

This works exactly one time. As soon as you disconnect, it reverts back. Note OP didn't want to know how to connect via MTP – but how to make that the default whenever the USB cable is connected. Your suggested approach works until Android 5 (Lollipop), but no longer with Marshmallow (Android 6) which OP explicitly asked for.

Yaa. It does reset back.

Marshmallow: Apps NOT battery optimized still seem to doze off
I have a Nexus 6P. I have disabled battery optimization for a few apps and yet those apps still seem to doze off.
Specifically those apps are 1) a sip client (csipsimple and bria) and 2) pushover.
It would be great if those apps would never sleep :-)
Is this possible?
--
Edit: I agree with CmosBattery below that this might not be the way to go. In fact, I have set battery optimization on all apps like it was before. As mentioned in my comment below, some apps, like Bria, suggest that we should do so (and maybe they shouldn't suggest this at all). After a few weeks with the suggested setting, I see no improvement in call reception and a reduction in battery life.
GCM allows developers to send high priority messages. High priority messages allow you to wake your app (haven't tested, but the Android documentation says that this is reliable). Could there be other ways?

Apps are designed how they are designed by each developer. Apps can acquire wakelocks and keep the cpu (for instance) from sleeping thereby allowing the app to stay active: http://developer.android.com/training/scheduling/wakelock.html
A great app will do this as little as possible especially as apps can set alarms to check the internet for updates or an app can wait to receive a push from an internet server.
Apps never sleeping is the wrong way to look at it and will do nothing for you but hasten the battery usage for typically no good reason.
If there's an app that stops working when it should stay working then the developer should be contacted so as to let them know you want it to continue working even after situations where it may have become disabled regardless of what happens.

Interesting. I have pondered your answer for a few days. For example, when you install Bria there is a popup that suggests you must do this. I assumed this was the way to go about the issue. It is also suggested on a few blogs. Nonetheless, I don't think the answer is a simple as contacting the app developer as they don't seem to agree.

High Priority messages sent through Google Cloud Messaging should wake up the device. However, it would be great if we could do that from an Android setting i.e.: always treat messages as high priority for app xyz

Some apps are not able to access internet when connected to Laptop's shared wifi on Ubuntu
In my office my mobile used to be connected to the office wifi. There I didn't face any internet problem, all apps work fine.
But in my home my mobile is connected to my Laptop's shared wifi and Laptop is running on Kubuntu 15.10. In this case some apps like Play Store, youtube, telegram, whatsapp and all browsers, etc. work well, but some apps do not work, sometimes partially work or otherwise show the message 'No internet connection'.
What's wrong with connection from my laptop to my mobile, and why are some apps working and some are not? How can I solve this?

Android apps can query android for the type involved: http://developer.android.com/reference/android/net/NetworkInfo.html#getType%28%29
Now as a wifi connection is a wifi connection, as long as an app is enabled for wifi, the app should work otherwise the app can detect and say there's no internet connection available if the app so chooses.
There could in theory be an issue or bug with using the laptop's shared wifi but if one app queries android and gets wifi connected then they all should.
You can try an app like 'wifi fixer' and see if it helps.
I don't think its possible for anyone to give a direct answer on how to fix it other than try this and this and this, etc.
That said, as a direct wifi connection worked in the past, get a wifi router or ap and it should be fixed. This is imo what you should do.

Locked Out of HTC One -- Unknown Password
I have an htc one me, I put a privacy protection but I forgot the password.
What can I do to unlock my phone?
I have tried the different passwords that I thought I used it failed. I really need to use my phone to contact my friends but I can't access it because of the privacy protection password.
Please help me to remove it.
My brothers tried to unlock it but failed and I am scared of taking it to the service centre, due to concerns about the quality of service.

Welcome to the Android Enthusiasts! Please take a look at our locked-out tag-wiki, which holds some first-aid and links to useful information on this topic.

If you can't remember your password , there is only one way to fix this but it will wipe all your data...
Follow this steps to fix this:
Turn off your device

Press and hold the VOLUME DOWN button, and then press and hold the POWER button.
Wait for the screen with the three Android images to appear, and then release the POWER and VOLUME DOWN buttons.
Press VOLUME DOWN to select FACTORY RESET, and then press the POWER button.

The boot may take some minutes

If you have enabled the Android Device Manager, this is a simple fix. Open up the device manager from a desktop computer and set a temporary password on the phone. You can use that temporary password to get past the lock screen. Otherwise, you will need to factory reset the phone.

Picture folder disappeared from gallery on Huawei Ascend G6
I have a Huawei Ascend G6, and my folder with more than 500 pictures just disappeared from my gallery. I regularly clean system with Clean Master. I did it a couple of times, downloaded DU Speed Booster and deleted it. I don't know what is the problem. Could someone help me?

What the problem is, is probably this:
Your clean master probably enlisted your 500 pics as worthy of cleaning, thus deleted them all in the process. Its just a thought, but its likely to happen.
I use ES Explorer to clean stuff on my phone, and I verify every single thing it plans to delete everytime I'm about to clean. You never know, it might include your wheat among the weeds!
Another possibility is what happens when the storage is almost full. Happened to me once, and witness a friend face same trouble. Storage was almost full, phone restarted, and everything personal info was gone, from pictures to videos to everything I put on. Perhaps one of those nightmares, but only happening to images.

Misc. files that I can't find but that take up about a half of available storage
I have the following problem: about half of my phone storage is filled by files that grouped as Misc in Android Storage app. The problem is that I can't find these files. If I open the Misc. category there is no files displayed that can fill up that much space (the same thing goes for ES File Explorer SD card analyst).
So the question is how I can find this files.
(I have a suspicion that it's some kind of remnants from BOINC application,  but this is not helping me in any way)

Storage screenshots (click images for larger variants)
Here should've been another image to illustrate the situation with analysis from ES File Explorer SD card analyst, but I don't have enough karma for that.

Feel free adding the URL to the 3rd screenshot as comment (after uploading it to imgur). Someone with sufficient "karma" then can integrate it for you. // One more suspicions are "tombstones", we've had that here before. Our storage tag-wiki might give you additional pointers.

You can try DiskUsage app (free), it shows detailed information about memory usage and also gives you option to:

Scan internal or external SD and graphically display space occupied by directories/ sub directories
Choose files / sub directories / directories for deletion
Re-Scan after deletion so that you can free up desired storage space

You could give more info as to what the app does rather than pointing us there?

i attached picture to describe app usage

@beeshyams thnx

Oh, I guess this helped. As I understand the ES explorer were showing this data, but it was not accounting for "Applications data" and correspondingly I was getting an impression of data that is there but not displayed.
Storage app on the other was confusing in another way.
This app is accounting for all of it and it seems that all the data is legitimate after all.

Consider these possibilities:

Do you have "Recycle Bin" enabled in ES Explorer? If so, check the Recycle Bin folder. Its easy to forget sometimes that your deleted files aren't actually deleted when using ES.
If you wiped-clean or reset your phone to factory recently, it might be keeping your previous data somewhere, normally in a .android folder somewhere.
Also you can enable to show hidden files in ES Explorer, maybe might give hints.
ES Cleaner too, run it and see what it finds and thinks you can clear. Most times, it provides the link to the directory where the files tantamount to cleaning are.

I can think of the above now. I hope it helps

A different kind of Safe-mode?
I was playing with some Xposed modules on Galaxy S4 Mini phone and then after applying some changes, it stopped booting and stuck on boot logo screen.
So, i tried to boot it up again in safe mode by holding Home menu during startup, as i did to solve earlier problems, but had no luck this time! Still stuck on logo. Then after a little bit of googling found another boot option that can be activated by pressing power button multiple times immediately after starting the phone until it vibrates by your keypress. Fortunately, it helped a lot and i could boot up the system and deactivate the problematic module and the problem got solved. :)
Before this, i knew only one way of starting Android in Safe mode, which was by holding Home button during boot until you see Safe Mode label on the edge of your screen and then all of your downloaded applications would be temporary deactivated. (Although, key combination may differ on other brands.)
But, when i booted up using this life-saving way by pressing power button multiple times,

All of my apps were loaded normally
There was no sign of Safe Mode label
And thankfully, Xposed framework seemed to be disabled
Although, i still got all other functionalities and even root access

What is this type of booting called? Is it some kind of Safe Mode? What Changes does it make to system/services/apps? Is it a feature of Xposed framework or is a part of Android itself?
I've done a lot of searching but found nothing technically well-documented about it.

Just a guess from your description: Not a specific mode, but simply telling Xposed not to load? There are different ways to achieve this, so this might well be one of them.

@Izzy Yes, it might be. Although, it seems unlikely that Xposed has such a deep integration with Android core that it can listen for keystrokes in very beginning steps of booting procedure.

@zxcmehran Xposed integrates into app_process and libart.so so as long as Android itself boots up, Xposed is also running and able to listen to lowest level events, including button presses on booting.

@GiantTree Thanks for your clearification. So it seems to be a fail-safe switch to disable Xposed...

After doing some more research specially on Xposed itself, found out this way of booting is a fail-safe option to disable Xposed Framework at boot time which seems to be a feature of the framework itself and have nothing to do with Android core. As mentioned in this thread:

Xposed for the most part is STABLE and SAFE. However, installing an
  experimental module or an old module can cause a boot-loop. If this
  occurs, there is a fail-safe switch to disable Xposed and exit the
  boot-loop. To disable Xposed, tap one of the hardware buttons (the
  Power button or a Volume button) on your device, SEVERAL TIMES, during
  startup. This means that pressing the Volume Up button, for example,
  multiple times (during startup) will eventually disable Xposed and
  cause your device to boot.

It says to press ANY of hardware buttons several times, so i was pressing power button several times! That's it!
Note that you might need to reinstall the framework after disabling it using this method. Rebooting might not reload the framework again.

I further assume that will leave a "disable flag" somewhere in Xposed's data directories. So if it doesn't load after the next boot, before re-installing check for that and remove if found :) Ah, here it is: data/app folder showing wrong folder names

Also see this XDA post :)

@Izzy, that can cause a lot of confusion. The post in the latter link says to create disable file but such file doesn't cause any effect. It is supposed to be named disabled. Absence of d causes lots of ??? in mind. :)

@Firelord that's why I've linked both – I vaguely remembered something with a "d". In this case here, simply delete both if they're present :)

What search can I perform to get a streaming app result on Google?
There are reports (see link below), that Google will now stream a small set of apps, when content in those apps match your search criteria. I have yet to be able to produce a Google search that shows one of these streaming app results.
I've tried using the example that I've seen in articles: "hotel right now in Chicago", from both the mobile web version of Google.com, as well as the Google app, but to no avail. The correct answer to this question will look something like:
"In order to see a streaming app result, you must be within the Google App, and you must use the following search: What is Sagittarius' horoscope for today?"
or
It appears from this link (www.example.com/GooglePulledStreamingApps) that Google is no longer streaming apps, or is only streaming them to a limited number of people.
I've also discovered (see 2) that this only works from the Google App on devices running Android 5 or 6. Although this feature of Google is only available on Android, I still don't believe this is an Android Community question, because it is specifically regarding how a search on Google behaves.

What are streaming app results?
Google App Streaming: A Big Move In Building “The Web Of Apps”
Google’s Going to Make Downloading Apps an Afterthought

Google almost always rolls out features like these in waves. It could simply be that you don't have it yet. As to the downvotes, I've no idea. Perhaps because people aren't familiar with the new streaming app feature in Google Search.

Where are you located? If it's outside the U.S. it probably won't work for you in any case.

@Al E. I'm in Topeka, KS, USA

For what it's worth, I installed "Hotel Tonight" and "Chimani" and did some searches, and neither app streamed for me. I'll try again tomorrow, but it's likely that this is only a test that isn't available to everyone.

Al E. The point of Google being able to stream the apps is that you don't have to install them. That's the "wow" factor at play. They are now able to index information within apps themselves, with the help of app developers.

That's not the impression that I got. The Search Engine Land article makes seems to say that the "magic" is that you can get the data from the app without having to launch it.

I think the clues are in the article from Search Engine Land:

If you have one of the apps above installed, Google will jump you from its search results on Android into them.

The apps "above" are currently:

Chimani
Daily Horoscope
Gormey
Hotel Tonight
My Horoscope
New York Subway
Useful Knots
Visual Anatomy Free
Weather Channel

Further, the article also mentions:

The requirements are Android 5 "Lollipop" or 6 "Marshmallow" or higher and to be on a strong wifi connection.

So, based on your sample search, you need to have Lollipop or Marshmallow on your Android device, a strong wifi connection, and the "Hotel Tonight" app installed. And it appears you'll need to use the Google app or search within Google Chrome (no other browser).
And if you're not in the pool of people they're testing it on, even with all of this you won't get the results.

Here's the part I'm interested in: "You will see them if you’re using the Google app, because of a new “App Streaming” feature that Google is also testing." In using the Google app though, and still haven't seen the option to stream an app. I've asked for my horoscope, I've asked how to tie a square knot ... The question remains, what question can I ask the Google app in order to get a streaming app result? I'm running Android 5.1.1 on a Note 5. I also see that my Google app is up to date.

From the Google App I was able to search for "hotel tonight Kansas City" and right underneath the ads I see the streaming result. http://imgur.com/hFRr2Jb

I tried the same from an iPhone (searched within the Google app for Hotel Tonight Kansas City), and did not receive the ability to stream the app.

How can I exit "Quick Mode" on Acer Liquid smart phone?
The Acer Liquid 630 received a Lollipop update in December.
I accidentally launched Quick Mode and now I am not able to exit. If I choose to end QM, the phone asks for confirmation but stays in Quick Mode. Before installation of the Lollipop update, leaving QM was possible.
This problem has been reported also in a recent comment on How do you take quick mode off Acer Liquid Z3?
Is there a way to disable or exit QM, or do I have to return to factory settings?

I have filed a bug report with Acer now, and resetted my phone to factory settings.
Update: three months later, Acer has not yet replied, but the phone has received two updates since December so maybe it is fixed. I will not test it as I might end up with another factory reset.

I don't have Acer smartphone, so I don't really know your attempt to exit QM, but have you followed the official manual from Acer?

@AndrewT. Yes, definitely.

Instead of a factory reset and install everything again, you can download a home launcher from appstore! Set your new home launcher as default then uninstall quick mode(sucks bigtime)... I like my phones new look, i even got rid of the left page on the homescreen. :-)

I deleted too many system apps but I made backup.. My tablet stuck on android logo
A virus similar to monkey test that I almost solved the problem with Titanium Backup app until I deleted too many system apps. Now my tablet stuck on android logo. However I backed up all apps with Titanium and copied it to my computer.
Please tell me there is hope. I almost solve three month problem by following steps with Titanium but I overdone it. I hope there is still a solution  with the backup I made. I really don't care about the data my problem always was that I never found a ROM for my device but I am no expert. It could be there and I did't not see it.
The virus was similar to the monkey test but it wasn't the same. That's why it was hard to follow steps latterly. Whatever it takes to get my device back it is so important for me. I will right the build number for the tab and upload all apps images and a video  for its settings ,model number and virus apps, only images was after deleting obvious virus apps. I really appreciate any help.
Build number: rk_30 android 4.1.1 sdk v1.00.00 bsmart bs101 v1.0 20130316.
[Video showing all info][2]
https://www.youtube.com/watch?v=hC-Km8pdOf8
i spent the past time trying to learn more about adb ,and i found this video when searching it could be the solution for my problem and i hope it is helpful video for others. i don't want to make the same mistake twice so i'm waiting for your advice before continue in these steps, also i put an image after i did the first step only to make my computer reed my tab on adb

Which Android device is it? It can't be helped now. You must find and flash the stock ROM.

it is bsmart 10.1" bs101 can you help me find any rom for it's cpu is cortex a7 dual core 1.3 ram 1g resolution 1280*800 16g nand flash ?

If you backed up the apps you removed, you should be able to just adb push them back to the device OR copy/paste to the system app directory if that's available from Windows/Linux (etc) file explorer. Assuming all you did was delete some apk's.
If you didn't and you can find a stock rom, you might be able to do the same but instead getting the apk's from the rom.
Its possible that doing so may not work (depending on how the rom is set up and what you have available) and that you need to (re-)flash a rom (even just a dirty flash of the same rom or newer should get you back in).
But what you should have done was a full backup via adb, made sure there was a rom available for flashing, or installed a recovery and made a full backup before messing around in the system section. BACKUP backup backup!
A more direct answer may be obtained from the device thread on xda website where multiple people likely know the device well enough to get you through it.

You're probably stuck on the logo because, you could've deleted a system app that was named com.android.bluetooth-20151217-190009 which is a PROPERTIES file. You might want to bring it in to the Google Store. This is why you do not mess with system apps! It brings a lot of trouble to your phone.
Now, if you deleted the apps because you wanted storage, That is not a good idea, because your phone may overflow with downloaded with apps and games, which is not healthy for your device. Bringing it to the Google Store, they may fix your problem.

thank you it was all about deleting the virus without enough exeperties, what is right command to paste it in cmd to do solve the problem

Problem with Genymotion
After I updated to Windows 10, Genymotion no longer works. I get this error message.

Probably a reinstall is in order as the update has reshuffled your drivers and devices

I found out that Oracle VirtualBox, which Genymotion is based on, doesn't install the network adapters correctly in Windows 10.
And the solution:

Delete all previous VirtualBox adapters
Try downgrading to VirtualBox 4.2.18
Go to device manager and click "Action" > "Add legacy hardware"
Install the oracle virtual box adapters manually (my path was C:\Program Files\Oracle\VirtualBox\drivers\network\netadp\VBoxNetAdp.inf)

Now that VirtualBox adapters are installed correctly, it needs to be setup correctly. (the following solution is like many other solution in here)

Start Oracle VM VirtualBox dependent Genymotion, and go to "File" > "Preferences" > "Network" > "Host-only Network"
Click "Edit"
Set IPv4 192.168.56.1 with mask 255.255.255.0
Click "DHCP Server" tab and set server address: 192.168.56.100, server Mask: 255.255.255.0, lower address bound: 192.168.56.101 and upper address bound: 192.168.56.254
Now click "OK" and start Genymotion.

Why has this answer been downvoted? Content organisation fixes are an edit away.

A clean Genymotion install will likely solve your issue. It's hard to interpret the error message as you're using the program in French.

Let me translate (Roughly).  Unable to start VM Genymotion. VM cannot obtain an IP address. Please restart VirtualBox after the problem has been fixed. (No google translate, it's horrifically inaccurate)

Try the following steps. Although this is standard troubleshooting, but it could still help.

Reboot your PC and run Genymotion.
If you still get errors uninstall Genymotion and reboot PC.
Reinstall Genymotion and try again.

TWRP: "E: Unable to mount storage" after encrypting phone
I get E: Unable to mount storage error in TWRP after encrypting my phone. CyanogenMod 12.1 ROM (based on Android 5.1.1, my phone is HTC One M7) in use, CM uses AOSP encryption that is supported by TWRP. TWRP doesn't work properly, I wasn't able to flash a script that used to work perfectly (no error, but flashing didn't do anything).
Should I do a wipe in TWRP? I already tried wiping the system and reinstalling ROM, no success. What partitions should I exactly wipe?
EDIT: I tested more and it seems that I can update my ROM and install the Xposed framework, but running scripts like freecyngn doesn't seem to work.

TWRP version 2.8.7.0

Doesn't TWRP ask you to enter a password to decrypt storage? Also, are you using the latest available TWRP version (2.8.7.0)?

Yes, I can access TWRP with my password. I'm using the latest version.

does changing MTP to disabled work ?

Will klte ROMs work on SM-G800F?
I want to install AOKP on my Vodaphone Samsung Galaxy S5 mini SM-G800F, however, the kminilte ROM is not yet developed.
klte seems the closest to kminilte, so will installing it brick my phone, or will it be successful? What features of my hardware will be voided by installing the wrong version if it successes?

Edit as I cannot add an answer as this question is a duplicate.
I actually started dabbling in things regarding porting (slightly modifying ROMs for different devices). And the differences are huge. In the script that initializes the rest of the system, it tests for different models of klte, thus not finding a result and not booting.
Regardless of that, the CPU, screen size, pixel density etc. is different.
If someone has an unsupported device, they can try to find the most similar supported devices to keep change to minimum. You can also look on the CM wiki for unofficial ports.
When comparing devices, I recommend the webpage http://pdadb.net/ as it gives very detailed info about android phones.

@Firelord I aggree, and I flagged my own question

Very bright chances of bricking your phone if you flash a ROM not specifically meant for your phone. Custom ROMs are made by developers to cater explicitly for models specified by them, and being "closest" to your phone model doesn't mean anything in this context. Please read these to get more understanding

Can I install a ROM made for a different device?:
Feasibility of flashing a ROM (meant for original device) on a re-branded device

I don't know if your phone is "tied to a carrier", or is not , but even flashing a ROM meant for a specific device and carrier on same device but different carrier can successfully brick your phone, and that is the reason developers also mention the carrier it will work on where relevant
Second part of your question, What features of my hardware will be voided by installing the wrong version if it successes?, is redundant given the explanation above.

CM 12.1 random restarts
I've got Cyanogenmod 12.1 and it randomly restarts. It seems to only do this when I'm using the phone, for example I've never had it restart when the phone was just sitting unused. Is there anyway I can prevent this or find what's causing it?

who's responsible for -1?

You seem to be having a nightly build and there is no way you could fix it manually. All you can do is report bugs or hope that a stable build comes around.

There are only nightly builds for CM 12 so I guess there's nothing that can be done. Would it be any more stable if I used an older nightly build?
