Hi,

I've a Redmi 7 phone and want to use my fingerprint to unlock it but I get every time a "Couldn't add fingerprint, try again". I've tried all possible solutions offered in this site as in other sites but without success. In CIT the fingerprint sensor test reports no errors.

The pecs of the phone are:

MIUI 12.0.1.QFGMIXM
Model M1901F7G
Android version 10 QkQ1.190910.002
Android security patch level 2020-10-01
Kernel 4.4.192-perf+

I hope someone has a solution.

regards,

Ivan
