There are various reasons why your mobile phone may not recognize fingerprints, and verifying fingerprints is one effective troubleshooting method.

Additionally, avoid removing your finger from the sensor too quickly as this may cause Samsung phone fingerprint recognition errors.

A scratched, damaged, or excessively thick screen protector can affect the device's fingerprint recognition. If you encounter this issue, clean the old screen protector or completely remove it and replace it with a new one.
In addition, if your device does not use a screen protector, you should also clean the screen with a soft, dry cloth and then try unlocking again.
