As per your query, we would request you to kindly perform the following steps to resolve your issue.
● Fingerprint sensor not working If your fingerprints fail to unlock the phone, and you are asked to type in the lock screen password, follow the steps to resolve the problem:
● Have you check your fingers: Ensure that your fingers are clean and dry. Note: 1: If the skin on your fingertips is peeling or cracking, or your fingerprint is difficult to capture, the fingerprint ID on your phone may not work. 2: If your fingerprints fail to unlock the phone while the phone is recharging, remove it from the charger and try again. If you are charging the phone with a charger and data cable from other brands when you use fingerprints to unlock the phone, they may interfere with the fingerprint sensor and cause the recognition to fail.
● 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 fingerprint.
● Remove the Screen Guard /Screen Protector: Samsung cannot guarantee compatibility with third-party products, as the thickness and structure of protective films or screen protectors may affect the performance of the fingerprint sensor. So if you are using third-party Screen Guard /Screen Protector remove it and try re-registering the fingerprint again.
● Remove fingerprint and set up fingerprint again: Remove the current fingerprint and set up fingerprint again. When you touch the sensor to set up 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.
