Fingerprint ID lost from setting - Huawei P9 Plus Questions & Answers

How could I get back my fingerprint ID features after it disappeared from the setting menu?

what have you done?
Is the whole fingerprint setting gone, or just your fingerprint id?

The whole setting has lost. What I still remembered, the problem was happened when I have installed an apps that might help me to kill or clean up wasted processes.

Same problem on my p9 plus. Fingerprint ID on settings suddenly disappeared. I did a factory reset but didnt solve the issue. After factory reset the sensor will work but after a deep sleep or when the phone was restart, Fingerprint ID is gone again.

Problem with fingerprint scanner

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.

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!

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.

How to turn off fingerprint scanner activating on lift after new update?

Anyone know if there's a way to disable the fingerprint scanner activating any time I pick up the phone now? Never did that before the update, it's pretty annoying. Already have lift to wake turned off, but that doesn't fix it. Went through every setting and didn't see a way to fix it. And it's not the lift to wake option, the whole screen doesn't turn on, just the fingerprint scanner and icon. Seems to be making my battery life way worse.

Because Blu cust support has not duplicated it, others with update didn't duplicate it.
Makes it seem like just your phone.
Did you try to factory reset it.
Fully. Remove saved fingerprint remove accounts,
Reboot to recovery and do factory reset. Setup phone again

Late reply I know but I found out how to disable this option.
In the settings go to:
Display->Ambient Display
Turn off the option for New Notifications.
I have no idea why it is called this as new notifications (SMS at least from my quick test) still wake the screen,but the fingerprint sensor no longer shows when you lift or move your phone. Completely mislabeled but hey at least you can turn it off.

Proximity sensor problem

hi guys, i noticed that my phone's "lift to check" and "double tap to wake" aren't working sometimes, and the screen went black when i make a call. therefor i downloaded sensor test app and figure out those are caused by proximity sensor stopped working occasionally, especially when i take it out from my pocket, i had to restart my phone to make it works again.
i searched over the internet and tried all the ways but still no luck. Action taken included boot to safe mode, clear the cache of phone app/ google framework/ google services, android ambient and etc... and i also reset the app preference, download sensor calibration app, factory reset, yet, the problem still appear. i have used my phone for more than a year, and this issue was just suddenly poped out recently.
appreciated if anyone here could provide a solution. Thanks
