Fingerprint doesn't work after 3 4 days of registering...

[Moni27]

1) Once I register the fingerprint on samsung galaxy M31s.. it automatically stops capturing after 4 days and says fingerprint not registered..

I have to remove them and again register.. same priblem happening from the day I had purchased the it.

2) Everyday in morning phone asks to enter the password to unlock even when there is fac unlock and fingerprint is registered.

How to solve..
