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

•

Samsung Pay

•

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.

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.
