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 your fingerprint is not recognised and you have forgotten your backup password,
you must take the device to a Samsung Service Centre to have it reset. Then, you
must re-register your fingerprints and create a new backup password.
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.
