I've experienced losing my fingerprint recognition. My fingerprint was working really well but after applying the latest red tint update, it seemed to become not as responsive. When this happens I find that booting into recovery mode and clearing system cache partition, then rebooting usually fixed it. If that doesn't fix it, i remove the old fingerprint and register my fingerprint again. Then it works excellent again. One quirk that i have is that it only seems to recognize only the 1st fingerprint easily but doesn't recognize a 2nd fingerprint as easily. Took me forever to tap my 2nd finger many times to get it registered and even after it did, that 2nd fingerprint wasn't recognized reliably by the sensor.
Has happened on 3 separate occasions for me where it just stops recognizing any finger at all and requires pattern input to unlock. A reboot always fixed it for me.

Stock or custom rom?

Fingerprint sensor stopped working.

Hi everyone. My fingerprint sensor randomly stopped working. I can't use fingerprint to unlock the phone, nor can I add new fingerprints in the settings menu. In fact, fingerprint is completely gone from the settings menu, it's like the phone doesn't have it anymore. I am on Pixel Experience 10, was working fine before.
Fixed it by reflashing dtbo.img
