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   
						

							Settings

•	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.
