(latest release 7.7.20 xiaomi.eu ) my finger scanner suddenly stopped to work... i tried with some attempts but nothing.
what would i have to do? before the sensor was working perfectly. Thanks for support.

wiping only solutin when you upgrade don't forget to turn off passwrord first it's better keep safe from bug on finger print issue
