My fingerprint sensor is not responding. I dont know what happens to it sometimes. It doesn't recognize my fingerprint. Very bad response from the fingerprint sensor in on series by Samsung.
Register fingerprints again. Make sure to cover every area and possible angles of a finger. If you use less than 4 fingers to unlock, you can even add fingerprints for same finger more than once with more possible angles and areas.
I don't have the device but did have my hands on. I realised that people use this sensor as the same way as the other optical sensors but that's where the problem might be. People generally hard press the screen which flattens the ridges of your fingerprints. So to avoid this just slightly touch the screen and I guess it shall work in the best way as it was designed to work.
I am not sure about your case but all assuming. Hope the solution works for you.
