Check for common issues with fingerprint recognition on phones.

When you scan your fingerprints on the device, be aware of the following conditions that may affect the feature’s performance: 

Inspect the screen for scratches and dirt.

• The fingerprint recognition sensor recognizes fingerprints. Ensure that the fingerprint recognition sensor is not scratched or  damaged by metal objects, such as coins, keys, and  necklaces.
• Ensure that the fingerprint recognition area and your fingers are clean and dry.
• The device may not recognize fingerprints that are affected by wrinkles or scars.
• The device may not recognize fingerprints from small or thin fingers.
• If you bend your finger or use a fingertip, the device may not recognize your fingerprints. Make sure to cover the entire fingerprint recognition sensor with your finger.
• To improve recognition performance, register fingerprints of the hand used most often to perform tasks on the device.
• The touchscreen may malfunction in humid conditions or when exposed to water. 

• To remove fingerprints or dusts, wipe the window glass smoothly with a clean and soft cloth.

• Fingerprint recognition is blocked when the device is under water.

Remove protective cases

• If a phone case covers or touches the fingerprint sensor, or prevents your finger from touching it, it can interfere with the sensor's operation.

Moisturize your hands

• The sensor may not work if your fingers are too dry or chapped. It may be helpful to moisturize your hands with hand lotion.

Remove protective cases

• If a phone case covers or touches the fingerprint sensor, or prevents your finger from touching it, it can interfere with the sensor's operation. 

Samsung recommends to use the device with Samsung-Approved cover accessories for protection of product appearance and user convenience. 

Remove your fingerprint.

If your fingerprint still isn't being recognized, you can try removing and then registering your fingerprint again. 

Navigate to Settings, tap Biometrics and security, and then tap Fingerprints. Select one of the stored fingerprints you’d like to delete. Tap Remove, and then tap Remove again to confirm. Repeat these steps to delete any other saved fingerprints. 

While you are still in the Fingerprints settings, tap Add fingerprint. Follow the on-screen instructions to register a new fingerprint.

Step 2. Tap OK on agreement popup to send system log data.
