Fingerprint scanner stopped working - Galaxy S6 Q&A, Help & Troubleshooting

Yesterday all of a sudden I kept getting this error with fingerprint scanner having to close. I disabled this method in order to unlock my phone faster, since fingerprint scanner didn't work even after several reboots. Now when I got to the fingerprint section in order I get "an error has occurred with the fingerprint sensor. If this message appears repeatedly, restart your device. " Obviously, restarting doesn't do the trick.
I tried the fingerprint test (via *#0*0 and I get "fingerprint initializing fail" (sic)
I've been looking all over to no avail. Thing I tried
- Clearing data/cache for the fingerprint apk
- Clearing davilk cache
I want to know if anyone found a solution prior trying a hard reset
I'm on: stock MM 6.0.1, rooted (have been rooted for more than 3 months, so this doesn't have to do with rooting). Phone didn't suffer damage of any kind

reflashing stock firmware could solve your problem...if you dont mind...!
if that didnt fix it up... it could the sensor (home button) problem.

you mean just reflashing, without factory resetting it?

get into factory settings and wipe as you said, yes
and then flash fresh stock firmware...
once again wipe, restart done!

[Q]Phone rebooting (PAC ROM)

I'm on the PAC ROM. Always worked great, with some minor issues. Today, I received a message on Whatsapp and, suddenly, trying to open it, both from the notification drawer and from the app drawer, caused phone to reboot. I tried killing the process from settings, it rebooted before loading all the running apps. After that, I've not been able to run anything without causing a reboot. Why is that and how can it be solved?
EDIT: I understood it is Smart App Protector's fault: every app works fine except that and all the locked apps. Trying to uninstall or stop it causes the phone to reboot, as well. Any idea on how to solve this?
Try wipe data/factory reset.
if the problem remains unsolved:
re-flash your rom (clean flash).
you can backup your data through recovery.

Thank you very much, it works now. But Google Play is stuck on the loading screen... Any solution to avoid reflashing?
EDIT: Nevermind, it is magically running again.

Yup, this is because Google play have to update itself and change interface directly after each data wipe

[URGENT] Every reboot results in a factory reset

So today my droid started messing up, home and recents button didnt work. Google play store and whatnot couldnt access data, the signal status bar at the top was just grey.
So i factory reset it. During the reset it just sat there on the little screen with the spinning hexball thing for like an hour so i shut the phone off. Now every time the phone boots it just tries to wipe it again unless i go into the boot menu and hit normal boot.
Running stock rom and whatnot, but im rooted.
I know that theres a flag somewhere that it reads on boot saying to wipe it, but dang if i know what to change.
Thanks in advance
Well i unrooted my phone and tried to let it redo the factory reset again, and it still just wont do anything.

When this happens to me, it's because of a bad flash and a factory reset won't fix it. I would suggest reflashing stock...

I dont have a custom recovery or an unlocked bootloader.
I managed to get the problem sorted out through some unrooting and some non stock system file deletion. Installed safestrap and got blurry hd running on it now.
Thanks.

[Q] Restart loop(not bootloop) - really weird

Hey lads,
I got a really weird problem and I've tried nearly everything I can think of. I had EMUI 2.3(b121sp06) and I tried the online OTA update to b307 if I remember right(was automatically suggesting the update) and at the update screen it loaded to about 99% and then stopped. Said not to press power while on this screen but obviously it wasn't going to finish. So I reset the phone and it started the "recovery loop", so basically keep trying to apply the update. I had to flash CWM to break out and flashed the whole system by hand(recovery,system,boot,cache,cust and userdata img files) and it starts up but it keeps resetting and seemingly it's random. Android boots up, I don't touch the phone--> boom reset. Weird thing is it even does it in recovery.
If I really want to explain the problem it's like as if my finger got stuck on the power button(that naturally made me think that the button might be f*cked), but booting into fastboot and not having resets cleared my suspicion. What I also noticed is that every time it boots up it doesn't recognize the sim card and I have no signal or whatsoever.
Tried multi tool unbricking method -> doesn't work
Tried factory reset from stock recovery(had to be fast so it doesn't reset before) ->doesn't work
Tried wiping dalvik cache and factory reset from CWM ->doesn't work
Tried killing battery by letting it keep resetting -> battery drained, reset loop stopped ->put the phone on charger->reset loop started again
I have no f*cking clue how can I get out of this, will keep trying though. Any help is appreciated, thank you!
Hi
Did you try to remove the Sd Card ? Honor 6 reboot is often due to faulty SD Card.
Which model do you have ? L04 ?
B307 upgrade sure ?
Seb
Yes, that was my first idea, still does it though. I have the L02 and I'm not positive it was b307, but it started with 3, could be b303 if there is one.
I don't know for L02 but for L04 there is a Full ROM that you can flash with the three buttons method. (Vol+,Vol-, power and put the ROM in /dload folder on the SD card).
Maybe there is such thing for L02 ?
There is, but as I said the phone restarts even in recovery. It's like the phone restarts every 30 secs except for fastboot.
if it's not SD card or internal flash problem so, it seems to be hardware related to me (
Would make sense but it occurred only after I tried OTA. Would be really surprised if that killed that hardware :-/

Unfortunately not, I'm out of ideas, trying to negotiate with the seller to sort something out, I think the phone is beyond saving
Same thing happened with me. Don't have any solution. Have you fixed it?

Its might be a battery problem Or power flex cable. Try to turn on the phone during charge
guys im facing the same problem now... waiting for any solutions
I have tried stop & uninstall some app
I've tried as quickly as I can when the phone (nokia x) is on, then I stop> uninstall I consider potentially cause this problem (facebook, whatsapp, uc browser) and then it managed to prevent the continuous restarts. but problems arise even though the application had me uninstall and then I restart the phone. and it is back again, I uninstalled the app that has remained with the error settings and restart repeatedly. who knows what else : '(

Did you follow the guide here?
Sent from my Honor 8 using XDA Labs
In the past my battery lost it's endurance pretty much. Furthermore I've read that a defective battery causes lots of weird behaviours on our Honor 6, which was the same to mine.
In my case a replacement of the battery worked well, to get my Honor 6 back to life:

It's not that difficult and lasts approx. 30-45 mins. Spare Batteries are available for 6 - 10 bucks on ebay or directly from the chinese internet stores.

It's really important that we use original chargers for the health of our device.

decryption problem / camera problem

Hello,
Im trying to remove the encryption on my Xperia XZ but it doesn't seem to go away.
Even when i factory reset the phone and skip all steps of the setup process, it's still encrypted.
Anybody knows what I can do? a little help is well appreciated.
Also my camera doesn't work anymore, it's just giving me the error "camera is being used by another application" ,
I tried resetting the app, wiping cache and wiping data. No results there.
Thanks!

Search threads, this has already been reported & fixed.

An error has occurred with the fingerprint sensor.

So, my fingerprint decided to stop working suddenly. It doesn't even work at all. i just get this message:
"An error has occurred with the fingerprint sensor. If this message appears repeatedly, restart your device."
What i have tried:
- Factory reset
- Reflash rom
- Flash different kernel
But none of this have solved it. I hope that someone knows how to fix this.
Thanks in advance

Hmm this is more and more looking like a hardware issue with the sensor
