Fingerprint sensor not working anymore for unlocking display

[patrickopreuss]

Hi,

yesterday the fingerprint sensor quitted its work for unlocking the screen.

I can add fingerprints, but when I touch it with any one of them while the screen is locked there is no reaction.

Please help!

Hi Patrick,

Fingerprint reading quality has lowered over time

Howdy all. When I first got my FF3, the fingerprint reader seemed to work most of the time, though the longer I’ve used it the more I’ve gotten feedback from Android saying “fingerprint reader dirty”, requiring me to wipe me finger off, the reader off, and try again. Sometimes it takes multiple attempts to clean them off enough to satisfy the sensor. I’ve re-added my fingerprint before but that hasn’t seemed to improve the success rate much. Has this been a trend other people have had? I found t…

Fingerprint reader not working after sudden reboot and failed boot process

This problem is solved at least for the time being, but I thought I’d document it here so maybe others with the same problem can try this very simple solution. Yesterday, after two weeks of working just fine, my wife’s FP3+ suddenly rebooted while she was using it. The boot process failed with strange blue patterns on the screen and the phone ended up in recovery mode with the options “Try again” and “Factory reset”. After selecting “Try again” the phone booted successfully, but the fingerprint…

My FP3 Fingerprint sensor is working so badly it's basically completely useless

I used a Huawei P10 for a while, which is a few years old, but has a great fingerprint sensor. It’s on the home button, you just touch it with your thump for a split second and it unlocks your phone / verifies your apps. I now switched to the FP3, mainly ideological reasons, but also because the dual sim meant that I would be able to use this as my private and work phone in one device. Sadly I have to say that the fingerprint sensor is so bad, it is basically useless! The position sucks. I h…

Android 10: no fingerprint for unlock

Did you install the Android 10 update with the manual installation method or via OTA? Answering that question will not help you immediately, but from what I read so far, the manual upgrade has led to some problems that don’t seem to happen OTA. Which would be an indicator to tell people not to use the manual upgrade method for now.

Hi Ingo,

thank you very much for the hints, but unfortunately none of them fits to my problem.

My sensor works perfectly, it recognizes each of my fingers in the settings, where you can add them for unlocking, and it worked also on the screen unlock until just some days ago,.

Now, when I try to unlock the screen, it is just doing nothing.

As a next step I will remove all prints, and add them again.

Well, removing and recreating my fingerprints did not change anything.

My banking app is working just fine with it, but not the display unlock

Probably it won’t change anything, but did you try to reboot the phone? Or to switch it off and then on again (not just reboot but really off and on)?

[patrickopreuss]

I rebooted several times, to no avail, but then I switched it off, and … magic happened!

Now it works

Thank you very much!

Never underestimate what seems like a stupid solution
