Since the latest update of One UI 5.1 on Dec 1st here in Canada, my finger print sensor has stopped working. I have 3 finger prints registered and not one is recognized. I have restarted my phone several times, run device care, cleared cache, and run diagnostics. I am getting the orange warning on the finger print test as it fails. The system recommends that I use some hand moisturizer to solve the problem.
You ran the Diagnostics for the Finger Print sensor?
You can try this:
Go to Settings > Apps TOGGLE ON "Show System Apps" (middle right) Search for "Biometrics", Click on it & Scroll down to Storage & Clear BOTH Cache & Data for the app & Reboot.
Have to think about this option. If I re-register new prints, then all of my biometric enabled apps will need to run the reset process again with two factor authentication etc...
Uising passcodes is bearable, but when I changed the order of my prints about a year or so ago, I was shocked how far reaching the consequences were. It even affected my wife's access to shared apps like our banking and insurance. It was a nightmare resetting all of the user accounts.
It is inconvenient right now, but manageable. Just disappointing.
