check for physical damage

Inspect the fingerprint sensor for any physical damage like cracks or scratches. Damage to the physical sensor can prevent it from reading fingerprints accurately. Replacing the sensor is the solution if it’s damaged.

Clean the Sensor

Fingerprint sensors can fail to recognize fingerprints if there is dirt, grease, or moisture on the surface. Carefully clean the fingerprint sensor using a microfiber cloth. Avoid using liquids that could seep into the phone. Cleaning the sensor may allow it to properly read fingerprints again.

Re-register Your Fingerprints

Go into the Fingerprint settings and delete any stored fingerprints. Then re-register the same fingers again. This forces the phone to rescan your fingerprints and may resolve any issues with improperly scanned fingerprints. Ensure you correctly scan the center of your fingertips when re-registering.

Check If the Sensor Works in Safe Mode
