1. Proper Finger Placement on the Sensor
One of the first reasons for Samsung phone fingerprint recognition failure is improper finger placement on the sensor. If you place your finger at an angle or with a curved finger, it can make it difficult for the sensor to accurately recognize the fingerprint.
To address this issue, make sure to place your finger correctly on the sensor every time you unlock your phone. Also, avoid pressing too hard as it may damage the sensor!
2. Check the Screen and Fingerprint Sensor for Scratches
Scratches on the fingerprint sensor caused by hard objects like keys, coins, or improper screen protectors are common reasons for Samsung phones not recognizing fingerprints.
In this case, you can address it as follows:
