i got a lollipop note edge from at&t and since a while fingerprint sensor stopped working, i tried many times to restore now even used a 4 archives stock rom to reset the phone ans nothing happens, could it be that its a physical damage??

That's what I've recently encountered using the latest Marshmallow on my G920F. Fingerprint scanner had been working totally perfect until now. I tried various methods to get rid of the problem (but it still persists) such as: rebooting, wiping cache/dalvik, reflashing kernel, removing lock screen security and wiping Fingerprints app data/cache. Any tips or solutions? The phone neither fell on the ground nor got too hot so the hardware is perfectly fine. In the past the phone also couldn't connect to the fingerprint sensor once or twice but turning the screen off and on again solved the problem in every case. I could also try reflashig firmware (factory reset) but now I'm away from my computer (holiday) and would rather try to fix it on the phone itself as long as it's possible of course.

Carrying out a full firmware flash would be your 1st option as you've already tried a few things already, if that still doesn't work then it points to a hardware defect.
So my S6 suddenly began showing "an error has occurred with the fingerprint fingerprint sensor. If this message appears repeatedly restart your device." when I click on fingerprints in the settings menu. I haven't dropped it or poured water on it. I've tried clearing data/cache in settings >application manager >fingerprints but the issue persists. I've not done a hard reset or reflashed the ROM cause I'm hoping there's another solution first. Dialing *#0*# to check the sensor isn't working for me cause for some strange reason my phone does not work with the secret Samsung codes. Device :G920F running stock MM with arter kernel. I would appreciate any help i can get
Have you tried to trigger secret codes with the App phone Info?
Use it with stock kernel and see any difference.
Hi all.
Last week my Moto g8 plus started to show message finger mooved too fast on locked screen randomly.
Then fingerprint sensor stopped working.
I have removed all fingers from it - no comments.
Now when I try to enable fingerprint sensor - it is not working. When cancelling the setup - phone goes into boot loop.
Did anyone have similar failure? Is it to be repaired by factory reset?
As far as I've searched similar problem appeared on Moto one vision but I haven't found any software solution.

I never had problem with fingerprint but you can try by factory reset ??* if it continues then install a new firmware
Did rescue with Moto rescue and smart assistant. Still the same story. Looks like it is hardware problem. I think I'm gonna request warranty service
I've just replaced the screen on my friends S5 Pro and currently don't have a working FP sensor. I've double checked and the sensor is seated correctly and there is nothing obscuring its little window on the screen.
I want to recalibrate the sensor, but cannot find a way to do this. All of the useful dialer hidden codes are disabled. It might be that doing a factory reset or re-flashing the full firmware would trigger the sensor to calibrate itself, however my friend spent days getting everything just how he likes things and says he'd rather live without the sensor than have to set everything up again and doesn't trust non-root backup solutions to work properly. He doesn't want to unlock his bootloader, so rooting is out of the question.
Does anyone know of any way to get into some kind of engineering mode on this phone to be able to force a fingerprint sensor calibration?

The fingerprint sensor went completely over the cuckoo's nest in my Umidigi S5 Pro for no apparent reason, now I can't use it at all. Any ideas?
Same thing happened to me shortly after an OTA update if I remember correctly... any luck with a fix thus far?
Hey guys,
i just did a factory reset on my Galaxy S7 (standard Android 8.0 from Samsung).
Before the factory reset the fingerprint sensor was working perfectly.
After the factory reset i get an error message when I want to safe new fingerprints.
I have to say that the home button is kinda scratched, thats why i get the error message - but it was still working with the saved fingerprints.
The error says sth like this (translated from german): "Please keep your fingerprint sensor clean and dry". As I said this is probably because the sensor is scratched.
After long searching on google I haven't found a solution for that so i kept on searching for different opportunities.
My question is, will a custom ROM like Lineage OS help on my error? Is there a way to safe fingerprints without having the sensor testing if everything is fine and just tries to recognize my fingerprints?
If you have any further questions to my problem just ask it. I am looking forward to your answers.
