My finger print scanner gone grazy... After update

georgeman74

After latest update my fingerprint scanner went crazy.  Without put my finger on it scans for fingerptint and i feel small vibrations very fast.  At my umi super lock screen.  So i cannot use it because after that says that there was to many attempts and i can try again in 20 seconds.  So i disabled this feature.  But why?  You do anything to fix this?  As i can see too many people have the same problem.

Hi
Definitely if your finger (or a bit condensation/moisture on sensor)  is a bit wet this could happen.
I would advice you to perform finger print calibration straight away when this fault occur.
Don't wipe sensor keep same condition as is making false reading!!!
To do this you need go to  settings - security - fingerprint - add fingerprint - CALIBRATION and follow instruction on screen

I have the same problem with the fingerprint. I updated my version to Android 7 and no more calibration for the fingerprint. So now it is useless.
