Hi,
My S7 crashed randomly and was stuck in a loop of the recovery menu. The short version is, I was fairly convinced it was a battery issue, and after changing the battery I was able to boot up successfully and (eventually) backup / copy off all my files. It wasn't esasy as it was constantly crashing and very unstable.
So, I did a full factory reset. This was via the settings menu after booting up and logging in because I couldn't access the recovery menu method. Factory reset has not solved my issue is still crashes usually after a few minutes at best.
Things that work
- Screen not broken, works perfectly, no dead pixels.
- No water damage / not dropped
- Volume Up and Down keys work (for volume and force power off when its crashed)
- Speakers / Microphone
- Both Cameras
- Wireless charging
- Cable Charging
- Full factory reset to latest stock android 8. Never rooted. Totally stock.
Things that don't work
- Vol Up + Home +Power to get to recovery menu / safe mode. Never managed to successfully do this
- I think it could be running a bit hotter than before, this may be subjective.
- Sometimes it crashes, screen powers off, but red charging light remains even when unplugged and it runs hot. Basically until the battery dies.
- Often crashes on first boot, e.g. during "samsung" boot screen. - Will restart and often gets to login on second attempt.
I've been testing via the diagnostics menu *#0*# (What a cool feature!) - Generally this is working ok, and nothing jumps out as failing, but its not easy as it crashes so randomly anyway. Can anyone recommend anything specific I should test?
So - Have I got a new Brick? Is there anything else I should do to try to save my phone? If it was smashed I could begrudingly write it off, but its in otherwise perfect condition! (3 months out of warranty!)
First time poster, any help appreciated.
Thanks

Can you flash latest unbranded stock? If still happens then it's battery failing. S7 is old phone now

Thanks, I've replaced the battery with a new one. Tried full factory reset a second time but it crashed and hasn't restarted since.
I think it must be a hardware issue. It thinks its charging when unplugged, gets hot when "off" won't switch off when crashes so need to wait for battery to die before recharging and trying again.
Yes, its old ish, but really only just over 2 years. My S3 lasted 4.5 years so getting half the lifespan from the S7 is really dissappointing. It was in perfect condition until this happened .

OK - since the recent ota upgrade to ICS we've been having a few problems with the table touchscreen freezing - unfortunately now it seems to have got stuck almost all the time. Just at the moment, it is not responding at all to touch - just displays the lock screen when powered on, and then times out a little while later to black. I have to push power to get it back on - but the touch screen simply won't respond to unlock it. So far I have tried:
Holding down power until restarts - no effect - reboots still locked.
Using Vol-Down power on and doing factory reset - no effect - reboots into android setup screen touchscreen not working.
Draining power until it won't turn on. Then recharged. This worked! However...
After going through the setup process, resintalling apps etc., I hit the power button to go into standby. I then thought I'd go straight back in, but as soon as I hit the power button again, it wouldn't respond! Left it charging for a couple of hours, and turned on, this time got in - but same again - hitting the power button and coming straight back in, it's not responding again.
So I'm now back with a fully charged tablet that won't respond to touch at all. - perhaps if I leave it a few hours it might respond again - until it goes into standby!? The device is fully stock with WW_epad-9.2.1.11-20120221 (according to the screen at boot up when you hold down vol-d).
Is this likely to be software or hardware related? Do I need to send it for repair/replacement, or is there something else I can try first? Any help much appreciated. (Oh - I don't have external keyboard btw - so without screen it's pretty limited what i can do!)
Cheers,
Colin.
I have already encountered the same problem but with a cutom rom. to find my touch, I had to do a full wipe and new intallation.
I did full wipe using the Power/Vol-D but the touch screen didn't start working again until I let the battery completely drain.
Then I reinstalled everything (screen was working to begin with), however after I'd set everything up and reinstalled all my apps it stopped again.
Yesterday I managed to get an ota update to 9.2.1.17 (it started working for a short time). But then aftger rebooting again, it stopped again.
This morning it is working again, and I have uninstalled all my apps - just the core stuff on there now. For the moment it appears to be working (which is the longest for a while!) - going to see if it stops again while there aren't any extra apps installed...
Hello all,
Today my Verizon S6 (on CleanRom 1.5) started to keep rebooting. After it boots, I can use the phone for less than a minute until it reboots again.
Here's how it began to happen today, if it helps.
- I didn't plug my phone to a charger last night, and when I woke up the phone had like 0%~1% battery. The phone died soon after I picked up the phone.
- At the same time I turned on the phone, I connected it to the stock charger.
- I used it for like 1-2 minutes, and the phone seemed to get confused whether it should die again or not (at 0% battery level)
- Then the phone decided to die again, and keeps rebooting itself.
My guess is something related to booting, initializing, or battery might have gone wrong. Also the soft button lights get never turn on.
Now I cannot use the phone really, as it dies like 30 seconds after I swipe the lockscreen.
- I tried to boot into safe mode, it didn't help.
- I wiped cache partition, it didn't help either.
The last thing I would like to try is to odin CleanRom again (or factory reset) but I would like to try other things first because I cannot even backup the data as it keeps rebooting. Odin will wipe all the data in my phone.
Any help or suggestions guys?

The OE2 tar file shouldn't wipe your phone as it is not a full wipe tar. I don't know if your phone would do it with it's reboot problem but a dirty flash of clean rom shouldn't wipe your phone either. However, a reboot during the middle of either of those would not be good. Flashfire does seem to be able to keep a phone from rebooting once it gets going or at least it has for me when I have been caught in a bad way before.
Problem Solved!!!
Thank you Tulsadiver for your suggestions. But is it okay to do odin without wiping anything?
I almost gave up after struggling several hours and thought about doing a factory reset, but the problem is solved now.
I found it weird that the soft key lights never turn on, so I thought that there might have been something wrong with the power management. So I turned the ultra power saving mode on (fortunately the phone didn't reboot before I did that), and it didn't reboot itself. I turned it back off then now the problem is gone!
I am happy with it now, and this might be one of the things to try if you experience a random reboot.
Hi!
Very weird situation. Before that everything was stock and OK (no custom ROM or anything).
- If the phone is unplugged, nothing works at all (key combinations,...)
- The battery is charged, at some point, when totally off, it showed the battery charging, 60% at least. But have not been able to go back into this mode.
- When connected, it starts booting, but keeps rebooting very fast (1-2 s after Samsung splash screen).
- Unable to boot into Recovery mode (UP+HOME+PWR, for wiping cache,...). Just does nothing, howerver long I wait
- Unable to boot "directly" into Maintenance Mode (all buttons), more on that later
- Can boot into Download (ODIN) mode (DOWN+HOME+PWR) very easily. I was able to flash stock ROM, but nothing changed.
- From ODIN mode I can boot into Maintenance mode (all buttons). I can navigate the menu, but any choice, even Factory Reset, gets me directly back to the reboot loop...
As I can not even turn it off, I cannot drain the battery (at least not quick). As soon as I disconnect the cable it goes dark (whatever mode I am in).
Anything I missed that I could try before throwing the phone?
Thanks!
SOLVED
Just to leave a trace on what happened:
- Left the phone alone, un plugged, for 8-10 hours.
- Just to see, tried to reboot it normally,
- It booted on a blue/cyan display, with "installing updates".
- At one point before I had that screen, but after 10 seconds it rebooted into the loop cycle. And after playing with the recovery reboots, I had never managed to get this special boot again.
- This time it stayed on "installing updates" for 1-2 mn, then rebooted, and Voilà!!!
So apart from my magic touch of doing nothing, don't really know what happened... So much for the recovery recipe!
A fairly similar thing happened to my girlfriend's g920v yesterday. We haven't been that lucky that it got fixed.
The situation is slightly different though, it boots for about 3 seconds, makes the low battery sound, battery indicator says 0%, then shuts back down.
Tried flashing stock in odin a few times, a few factory resets, nothing.
It seems like an OTA update failed and now the stupid locked bootloader won't let me or the or OS fix it.
Sorry you were not as lucky... But as you said the problem seems a little bit different, as I never had an empty battery warning. I agree though that it looks as a bad update stuck somewhere.

There's got to be some connection of some sort, yours is the 4th post I've seen here or on Reddit this month about bootloops probably related to updates
Yesterday I put my phone to charge over night and when I woke up today's morning I was met with a Black Screen with a status bar and Software Back button, that doesn't do anything. Rebooting in recovery doesn't work (TWRP just stuck on loading screen). I can receive notifications, but can't interact with them. I can Turn on and off Wi-Fi, Bluetooth, GPS etc. through status bar. I can't open Settings or any App. I can't reboot with out removing battery, can't hard reset and if I power off phone from Power menu it won't start again, when I hold down Power button, unless I remove battery.
Some Details about phone:
LG Max x155
Android 5.0.2
Custom AOSP (installed long time ago, never faced this problem)
TWRP 3.0.3.
I searched internet and tried some things:
Rebooting (didn't work at all)
Hard Reseting (didn't work at all)
Removing Battery putting it back and then powering on (didn't help)
Entering Safe mode (didn't help, it shows same issue, though it briefly shows my Home screen before going black)
Doing anything with Recovery, like wiping, reinstalling ROM etc. doesn't work, because TWRP won't load
Some other details:
I am using different charger (but I have used it for several days already). Phone was overcharged over night.
Now I am trying to drain the battery to zero and then charging it again, using my old charger. If it won't help I don't know what can be done.

Do a google search for:
"Return to stock (your model number)"
Then reinstall TWRP, then flash your 5.0ROM and Gapps. Don't forget to factory reset, wipe cache and wipe dalvik cache when you flash the ROM.

I figured it out. My SD Card burnt and caused this issue. I removed it and the phone's fine.
I tend to use my pad for traveling mostly, so it has been unused for about 6 weeks.
I turned it on a couple of days ago and all was fine until overnight it went into a reboot loop (or so I thought).
The following day it was dead, so I recharged it (during which it was rebooting constantly).
It would reboot every 10-15 seconds, even it it was in Recovery or FFBM mode.
The fact that it would reboot whatever mode it was in meant (IMO) that it was a hardware issue and not a software one, and the likely culprit was the power button. (It was acting like the power button was constantly depressed).
Using a pin I was able to lift the power button slightly and sure enough the pad booted and showed that it had pretty much fully charged even whilst rebooting.
As soon as I removed the pin it went straight back into a reboot loop.
Does anyone have any ideas how i may proceed to fix this issue? (It may even just be a humidity issue on the fingerprint sensor as I live in a highly humid country.)
I can't even work out the best way to open the case as there don't seem to be any tear-downs..
Thanks
Mine happen same issue with this, solve it by using
Step 1 : Spray 3M™ Quick Drying Contact Cleaner 16-102, around the Power Button Area.
Step 2 : Apply 3M™ AR-100 Anti-Rust lubricant.
So far after 1week, not more repeated
