Problem with fingerprint scanner - Huawei P9 Questions & Answers

Lately the fingerprint scanner won't unlock the phone. There's no vibration indicating wrong fingerprint, it just does nothing. When I unlock the phone using PIN it works fine opening top notification panel or scrolling through photos. When I go to settings and fingerprints manager it recognizes my fingerprints without a problem. Even when I lock the phone it works well for couple of times but after a while it stops working again.
Have anyone had an issue like that?
I already switched the phone off and on again but it changed nothong.
Any advice besides resetting to factory settings?
Thanks for any help

Are u using something like double tap to lock.
If so, disable it.
Otherwise, go to backup and reset, and reset only settings.

Lock Screen Fingerprint Unlock

I have my lock screen set for fingerprint. If the device is shutdown or restarted, the lockscreen asks for a fingerprint. After that if the power button is pressed to shut off and lock the screen, the next time it is turned on the lockscreen asks for just a swipe. It wont ask for a fingerpring again until the system is restarted again. Anyone else have this problem? Solutions?
You have to go into settings and set the power button to lock device. Or you can change the settings to lock device after a certain period of time.
It's under Lockscreen/Secure Lock Settings

You can also set it to not lock if it's connected to a certain device, like a Bluetooth.
This is a god sent because it's always been a pain to unlock the phone in a car after it's gone to sleep and you are streaming music from it.
Thanks! That was driving me crazy. I knew it was there, but couldn't find it.
I know what you mean! It was confusing the heck out of me in the beginning but then caught on.
How do one wish to switch back to just a simple swipe after choosing fingerprint unlock
The SWIPE option is now greyed out ??

Face recognition glitch

Originally I had set up face recognition along with fingerprint reading to unlock my S10. I've been troubleshooting my problematic FPS so I went to disable face recognition however I noticed the lock screen is still expecting it and an error pops up at the top stating "There was a problem with your face data. Register your face again."
I've double checked that face recognition is not enabled anywhere, is there something I'm missing? It seems like the phone still thinks it is enabled even though I have no registered faces anymore
Can anyone duplicate this?
Try switching to security "none". This will delete all your fingerprints and face data. Then enable fingerprint unlock again.

Where can that be done? I tried setting the lock screen to pattern only and deleted my face and fingerprint data.
I reregistered a face a noticed that even with the face unlock off under Lock Screen -> Screen Lock Type, the phone is still trying to use it
I think a reboot after turning everything off did the trick!

Note 9 sudden shutdown after rebooting

I have never encountered this problem before, until today.
My note 9 has been shutting down on its own moments after I turn it on, even when I'm not doing anything with it.
I need help. Thank you.
Does it reach the lock screen at all? If yes, do you happen to have fingerprint lock enabled? Try disabling it and see what happens.
I could get through the lock screen, but then the phone would turn off afterwards.
P/s: I disabled the fingerprint lock and remove all of the added fingerprints, and everything seems to work again. However, when I try to setup a different method for lock screen, the phone would turn off after I draw my pattern.

So I actually just factory reset the phone, and the problem would occur again if I use anything related to fingerprint sensor. I tried rubbing alcohol, but that didn't work. Maybe I'll try putting the phone into rice.
P/s: The crashing issus upon trying to changing security method happens again after factory reset.

Fingerprint problem after changing screen

Hey everyone,
I just changed the screen (with the full assembly) on my P10 and I have a weird problem with the fingerprint sensor.
I can add new fingerprints just fine, and if I try to set the same finger 2 times I get a message saying I've already saved this fingerprint. But, I can't seem to unlock my screen with the scanner. The screen wakes up when I scan my finger but the phone doesn't unlock even if the option is activated in the options.
I really don't know what to do.
Same problem here, is software related problem. Try to do a factory RESET. In my p10 was solved on the pie update.

Serious practical problem lock screen

Strange thing is happening recent to me...
Namely, while using headphones while talking on the phone, the unit gets unlocked while in pocket and problems arise with spontaneous keys getting activated.
If even cannot be explicitly locked by pressing the power button.
Have not found a solution to this problem, and it's strange why the proximity sensor does not work in pocket.
Cannot remember whether this was previously, or is it since last ROM upgrade.
Anyone having same problem?

Yep I have the same thing... Today my pocket took 9599295 pictures and movies.. also when I'm a bit sweat my pocket dial random numbers. I've noticed that when screen is touched and disnt recognize fingerprint then whole lockscreen shows up and its easy way to random open dial or camera... Its rly anoying, because I dont want to hide phone screen outside of the skin. (Its easier to break screen if I hit something with my leg.)
Dunno why it doesnt use proximity sensor to recognize that phone is in the pocket like every other brand... :/
Do you have the double tap to wake up activated?
I had this problem a while ago and it was the double tap that played all kinds of tricks calling emergency and taking pictures in my pocket! Disable double tap to wake up screen and the problem goes away.
Disable the fingerprint icon on when the screen if off.

Tried everything but the problem is eventually still there. Actually I've found a bug, namely the display will wake up once touched several times near the center of the fingerprint reader. Try it yourself.
Not nice - cannot avoid to happen it sometimes even if all options are disabled.

I didn't have this problem. If I try now and touch the part with the scanner, doesn’t have to be just the centre of the scanner, rapidly around ten times the lock screen will turn on, but nothing happens when I touch the shortcuts. Perhaps they are disabled, so the only thing that happens if the scanner is touched again is that the numpad to unlock with pin appears.
This is not good as it may severely affect battery life if it happens a lot. This clearly must be a bug!

Even worse, since it is happening all the time while on a call via BT and my phone is in the pocket. I am now thinking about to switch over to my old MI8...
Cannot understand why the keyboard is not disabled in the pocket. Seems so easy to do it but it's as it seems on.

My only solution was to buy a flip case. At first, I disabled the fingerprint reader by removing all fingerprints and setting up face recognition, but this didn’t fix the problem you are talking about. I don’t really like flip cases, but the Nillkin QIN Smartcase is rather good.
So now I ‘m eagerly awaiting a fix from Xiaomi so I can strip the Mi9 again!

Disabling the fingerprint icon has no effect on the problem we are talking about here. The only way to make the problem go away is to remove all the stored fingerprints thus disabling the use of fingerprints all together. This will shut off the fingerprint sensor doing away with this problem in a crude way.
If you really are looking for a setting, please use the search function at the top of the settings.
