Fingerprint Scanner Issue - Huawei P20 Pro Questions & Answers

Hi,
Recently the fingerprint scanner on my Huawei P20 Pro has stopped working. I have tried to resetting the settings and deleting the current fingerprint but it does not seem to work.
Every so often the fingerprint scanner vibrates without any contact.
Problems seem to have started after the latest software update. Does anyone have suggestions of how I could fix this issue?
Thanks.

I have the same issue. Fingerprint scanner is not working. Everything else seems to be ok. Any solutions that don't involve a hard reset?

Fingerprint sensor stops working

Had my S8 plus for about a month now. Every 2-3 days or so, the fingerprint sensor stops working just randomly. Will work perfectly, then just out of nowhere, doesn't respond to anything. Disabling fingerprint security and re-enabling doesn't fix it. Trying to go into applications- system apps- fingerprints, and trying to force close it won't work as it's grayed out. The only thing that works to get it working again is a restart. Not the end of the world I know, but having to restart it at the most inopportune times is kind of annoying. And paying this much for what amounts to the top of the line phone on the market right now, and having one the most important functions just stop working all the time is crap. And no I don't want to use the iris scanner, or pin, or pattern security. I want to use the fingerprint sensor.
Searches around the web indicate this is pretty common. Anyone else on the VZW S8 or plus having this issue? Anyone know if a fix is coming down the pipeline? I'm pretty sure this would be a software issue as it works 85% of the time and a simple restart gets it working again.

Some other threads on XDA have said that disabling fingerprint scanner gestures fixes it. I haven't ever used those and I have never had a problem with the sensor. It isn't as good as the sensor on my Moto Z Force Droid was, but it is pretty good.

Yeah, I disabled that last night. Waiting to see if that works or not. Just thought I would post in the Verizon specific forum to see if any other Verizon users are having this issue. Pretty sure it's a software issue, and am just curious about differences between the Verizon software and other carrier specific software.
Always had the gestures disabled and I have noticed this, but it always goes away with time for me. I thought it was just because I was sweaty at the gym, but it doesn't even know that I am attempting to use the scanner. Then, it happened outside the gym. Goes away in just a couple minutes, thought it was just me.
It seems that the fingerprint scanner is more reliable when the screen is off than it is when the lockscreen is on looking for iris scan.

does anyone facing fingerprint issue post oreo update?

Post oreo update I'm facing fingerprint response issues. It is not responding at least once for thrice.how to fix this?
No one problem here. Try to reset your phone. I've done this and solved some bugs like smart lock not working.
Or maybe clean your fingerprint sensor and rescan your finger with different positions.

Note8 Sensors error - Any of you faced with?

I have Note8. It has a very strange sensors error, as below:
- All sensors, from proximity sensor, light sensor, to GPS, iris scanner, and all the other sensors do not work at all.
- In the app like Phone INFO Samsung, CPU-Z or AIDA64, in the Sensors section, all sensors do not work.
- The Auto Brightness function does not work (due to the light sensor), the brightness of the AOD screen is also not adjustable.
- When making a phone call and move the phone close to the ear, the screen does not turn off due to proximity sensor.
- Auto Rotation function is not working (due to rotation sensor).
- Google Maps shows inaccurate location. Other apps that rely on GPS (such as the speedometer app) are completely not working.
- The iris scanner function does not work either.
It was about two weeks ago. I've Wiped the cache, restart the phone but does not make sense.
Yesterday it suddenly returned to normal, I don't know why.
But today - while I'm typing this post - all sensors suddenly do not work again.
Any idea about the error and how to fix it?
Thank you guys
Best advice I can think of is to factory reset and see if that alleviates the problem.
If you did not do anything firmware-related, or you did not drop or submeged your device, the best you can do is to make a warranty claim, pure and simple, if you have no way to make such claim, well, next time you should consider getting a device from an official source
I've read other users have had same problem. Ones I read said it was motherboard issue had to have sammy replace it.
Thank you guys
There is also built-in sensor test. Open dialer and dial *#0*#
I noticed a problem when I was playing Asphalt (racing game on me Note 8). I am unable to use the Tilt controls to move the scar.
Testing out the Sensors using *#0*# at the dialer revealed that all the SENSORS was faulty.
I reset the whole phone just now. The issue is still there with the sensor. As expected Auto rotation doesn't work.
Running the latest version 8.0.
I recently changed my motherboard (under warranty) 3 months back cos something was faulty. Seems it may be another motherboard issue.
Anyone else in this thread solved the issue?

Fingerprint Sensor Acting on its own

Hi,
I'm having a problem with my Galaxy Note 9. I just recently updated to the latest firmware which is N960FXXS5DTE2 Security
Patch 1 May 2020 and noticed that when my phone is locked, the fingerprint sensor is acting on its own. Then I get a message saying there have been 5 or more attempts to unlock the device. I tried a factory reset, still the same and also tried the sensor test which gave a PASS to all the tests.
Is it a software glitch? Anyone has this problem also?
IDK if this will help but try turning off Battery Optimization for the Samsung Biometric app. (Forgot exact app name, its something like that). I was having an issue with mine and doing this fixed it but can't guarantee it will work for you.
already disabled most of the optimizations but the fingerprint scanner acts on its own constantly. You have another suggestion?

Fingerprint Scanner/Home Button Not Working

I was setting my P20 Pro up as a spare phone today and when I went to setup fingerprint scanning, the option to do it was no longer there (Biometrics and password section). I checked out the Security and Privacy settings just to be sure, and it does look as if fingerprint scanning is not available anymore. The home button function doesn't work either.
I've seen people complaining that this has happened with other Huawei phones, usually after a software update. Huawei recommends restarting and resetting the phone to see if this fixes it, but it doesn't on mine.
Has anyone else had this problem with the P20 Pro, or any other Huawei fingerprint scanner equipped phone? Does it seem to be a hardware or software issue? What fixes are there?
