Samsung Galaxy S23 Ultra How to Test Fingerprint Recognition for Faults
12Sonetimes your phone’s screen can create some trouble that might stop your fingerprint recognition from working so u could Simply try wipe your phone down with a microfibre cloth and try again. If your S23 Ultra display is fine, it may not be registering your fingerprint because your finger is too dry or chapped. Try using the fingerprint scanner with moisturized hands and see if it works.If that doesnt solve the issue then u could try remove the screen protector if u have 1 applied & If that still doesnt resolve the issue u can run the fingerprint sensor test to see if its a hardware issue like shown in the video That will help narrow down the problem to determine if its a hardware or software problem..
