Android fingerprint sensor won't recognize your finger
The fingerprint sensor fails when your finger or the sensor itself is dirty, wet, or damaged. Clean the sensor and your finger with a dry cloth. If it still doesn't work, your fingerprint data can be corrupted — delete and re-enroll your fingerprint and it will work again.
Fingerprint sensors read the ridge patterns on your fingertips. If the sensor can't get a clear read, it won't recognize you. This happens when there's dirt or moisture on the sensor, your finger is wet, or the fingerprint data in your phone got corrupted. We'll clean the sensor, re-enroll your print, and test if the issue is just one finger or all fingers.
