    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.
    •	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.
    •	If you bend your finger or use a fingertip, the device may not recognise your fingerprints. 
    Make sure to cover the entire Home key with your finger.
    •	To improve recognition performance, register fingerprints of the hand used most often to 
    perform tasks on the device.
    •	In dry environments, static electricity can build up in the device. Avoid using this feature 
    in dry environments or before using the feature, discharge static electricity by touching a 
    metal object.
