Cannot Add New Fingerprint on Galaxy S21?

If you encounter some error when attempting to register your fingerprint like your phone is unable to register or recognize it, care to scrutinize the screen and fingerprint sensor for dirt and scratches. These factors may prevent the phone’s fingerprint sensor from recognizing fingerprints. Also ensure that the finger you’re trying to register is clean and doesn’t have any scars or wrinkles on it. The size of the finger is also another factor to consider. Small or slim fingers have higher chances of not being recognized.
