Here are some potential solutions to fix the problem:
Remove and Re-register Fingerprints: Try deleting your existing fingerprints and then adding them again. This can often resolve software glitches with the sensor.
Check for Physical Obstructions: Ensure that both the fingerprint sensor and your fingertip are clean and dry. Dirt, moisture, or a poorly applied screen protector can interfere with the sensor's ability to read your fingerprint.
Test in Safe Mode: Booting your phone into Safe Mode can help determine if a third-party app is causing the problem. If the sensor works in Safe Mode, you may need to identify and uninstall a recently installed application.
Factory Reset: If the problem persists, a factory reset may be necessary. This will erase all data on your phone, so it is crucial to back up your information first.
Contact Support: If none of the above steps work, the issue might be hardware-related. You should contact Samsung support or the seller for further assistance.
Disclaimer: A factory reset will erase all data on your phone. Make sure to back up all important information before proceeding with this step.
