Fingerprint recognition

In order for fingerprint recognition to function, your fingerprint information needs to be registered and stored in your device. After registering, you can set the device to use your fingerprint for the features below:

Screen lock

Web sign-in

Verify Samsung account

This feature may not be available depending on the region or service provider.

• Fingerprint recognition uses the unique characteristics of each fingerprint to enhance the security of your device. The likelihood of the fingerprint sensor confusing two different fingerprints is very low. However, in rare cases where separate fingerprints are very similar the sensor may recognise them as identical.

If you use your fingerprint as a screen lock method, your fingerprint cannot be used to unlock the screen after restarting the device. You must unlock the device using a pattern, PIN, or password you set when registering the fingerprint.

If your fingerprint is not recognised, you must take the device to a Samsung Service Centre to have it reset. Then, you must re-register your fingerprints.

For better fingerprint recognition

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

The Home key contains a fingerprint recognition sensor. Ensure that the Home key is not scratched or damaged by metal objects, such as coins, keys, and necklaces.

The screen protector supplied with the device may cause the fingerprint recognition sensor to malfunction. Remove the screen protector to improve fingerprint sensitivity.

Ensure that the fingerprint recognition area and your fingers are clean and dry.

The device may not recognise fingerprints that are affected by wrinkles or scars.

The device may not recognise fingerprints from small or thin fingers.
