Dear Samsung Member,

Greetings from Samsung Customer Support!

As per your concern, we would request you kindly perform the following steps to resolve your issue.

Clean the fingerprint sensor:
Clean the fingerprint sensor with a soft cloth. Make sure the fingerprint sensor is dry and free from any debris that may cause the sensor to be unable to recognize fingerprints.

Remove fingerprint and set up fingerprint again:

Remove the current fingerprint and set up the fingerprint again. When you touch the sensor to set up your fingerprint, make sure you set the entire fingerprint, including the outer area of your fingertip. Setting the entire fingerprint area enables successful fingerprint recognition with any grip.

How to remove Fingerprint: Settings > Biometrics and Security > Fingerprints > Fingerprint1 > Remove > Remove again to confirm.

How to Set up Fingerprint: Settings > Biometrics and Security > Fingerprints > Add Fingerprint > Scan your fingerprint > Place your finger on the sensor, then lift it off when you feel a vibration > Continue >
Reposition your finger each time to capture the edge of your fingerprint > Tap on Done.
