Hi guys,
I have a strange issue with my phone. After the upgrade to 7.0 my fingerprint sensor has stopped working. When i try try to access it it says that an error has occured and prompts me to restart my device. The weird thing about it is that it is very warm to the touch every time my screen is on. After a reset to factory settings i see that the sensor is getting warm after the security initialisation on the first setup. I have two guesses:
- it is a hardware issue
- the sensor is constantly being used by some background service and gets into error.
I tried to downgrade to 6.0.1 but odin keeps crashing at cache.img .
Any ideeas on what to do ?
Thanks !
Probably a hardware issue mate, I'd get it checked out

Hi guys! So I am facing a situation with my S5,it started only a few weeks ago. The problem is my S5 sometimes goes on a reboot rampage, first it would get stuck on some app, then it would vibrate once and then restart again with two vibrations. After that it would get stuck on home screen and keeps rebooting it self in the same manner. And after some time of repeating this process, it would start working properly.
Now I believe it to be related to either a motherboard or a battery problem.
So can you guys tell some way to check my motherboard without opening my device?

Try to flash stock rom via odin.
Hey guys i bought a s7 edge 930F and i get random reboots. Tried installing supermanrom, same result, factory reset didnt worked ether and yes auto-restart is off.
everytime that happens, the screen freezes for some seconds and after that it reboots. Is that a hardware error? and how could i create a log in that moment (perhaps that would help to figuere out the problem)?
Moreover: if i decide to replace the motherboard, will the fingerprint sensor work with the new board?
After successfully installing the official Oreo Update for my Samsung Galaxy s7 edge it suddenly started freezing up randomly and restarting itself, at first I thought it was not a problem, but it got so big I can´t even start my phone anymore, and yes I have tried everything except Odin, reset it manually, wiped the cache, and now I do have a blackscreen with my LED sensor blinking in blue and my touch keys lightning, I have no clue what to do, since my phone doesn´t react on anything anymore, neither the on/off button, won´t let me get into the donwload mode either, anything I can do to fix this? about to despair
hi guys...own samsung s8 sm-g950fd on android pie may security udate installed...2 days ago it started to reboot itself when the screen is off. If in use no rebooting noted. It did it randomly..very annoying..sometimes the phone goes off and refuse to boot despite pressing the power button until you scream...then later it boots
what I have done so far
1. factory reset no change
2. safe mode...becomes unstable and usable
3. reinstalled firmware(android 8.0 and 9) via odin..no change reboots randomly
4. rooted and installed custom rom renovate ice 15.0..no change reboots randomly

Most probably motherboard issue and should be replaced if possible ,had same issue on s7edge with random reboots ,shutdown not turning on ect
Hi guys, regarding the restarting issue...have some “improvements” after deleting data in apps...phone and device maintenance....15 hours without restarting..fingers crossed
Hi guys....the restarts have become too much to the point the phone is unusable...its worse when the phone is on 4G/LTE...Sometimes the screen goes dark and the phone becomes unresponsive.
My effort to take to the Samsung centre for repair has been in vain...as I bought the phone overseas and the warranty is not honored here.
Any help will be appreciated...
I've just replaced my screen and was stuck on infinite loop. It turned out to be the fingerprint sensor, in order to bypass the infinite loop, I disconnected the sensor and reconnected it.
So now that I managed to get in, I headed to the security settings, deleted all previous fingerprints. However, I keep receiving "Enrollment was not completed. Fingerprint registration error, please try again."
Update:
so I've found 2 threads on xda, that deals with that error:
https://forum.xda-developers.com/t/guide-fix-persist-img-loss-of-finger-print-sensor.4125909/
https://forum.xda-developers.com/t/...y-to-calibrate-the-fp-sensor-via-808.4217197/
However, now fingerprint is not showing at all! wondering if someone has any clue how to solve this
Update 2:
Update:
I wanted to see what would happen if I updated Oxygen to the latest update, turned out it brings back the fingerprint, however it seems that I've lost access to the vendor folder (unable to browse the directory under "/mnt/vendor"
