Please perform the following steps: > If any screen guard/tampered glass/protection film is available then first disable the fingerprint settings and then remove the screen guard. > Once screen guard is removed now register the fingerprint again and check the issue > If problem does not get resolved, run the device in Safe mode and reconfigure the fingerprint. > If issue still persists, create data backup and reset the device. > Make sure to use the central fingerprint parts evenly when you register or scan fingerprint, so that all portions of fingerprint, including the center and corners have been fully scanned.
