Fingerprint not working after screen replacement
have replaced the screen (whole unit with frame) on this Xiaomi Mi 9
afterwards the fingerprint Sensor did not work properly. It hardly Scans the initial fingerprint but won’t unlock the phone with it or allow any other fingerprint functions.
I have already removed it and replaced it again. as it is embedded into the Display Unit I Wonder if this is a problem concerning the display unit or the fingerprint scanner itself.
if it is the fingerprint scanner, would it even be possible to replace it or is it like on iPhones „married“ to the motherboard?
would appreciate your support guys
