Fingerprint recognition

In order for fingerprint recognition to function, your fingerprint information needs to be
registered and stored in your device.
This feature may not be available depending on the service provider or model.
•
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.
Thick protective film can affect performance. If you use a screen protector, check
•
to make sure it's labeled as compatible with the on-screen fingerprint sensor.
(such as screen protectors sold by Samsung) (Galaxy S22 Ultra, Galaxy S22+,
Galaxy S22, Galaxy S21 Ultra 5G, Galaxy S21+ 5G, Galaxy S21 5G)
Thick or colored protective film can affect performance. If you use a
•
screen protector, check to make sure it's labeled as compatible with the
on-screen fingerprint sensor. (such as screen protectors sold by Samsung)
(Galaxy S21 FE 5G)
If you use your fingerprint as a screen lock method, your fingerprint cannot be
•
used to unlock the screen for the first time after turning on the device. To use
the device, you must unlock the screen using the pattern, PIN, or password you
set when registering the fingerprint. Be careful not to forget your pattern, PIN, or
password.
If your fingerprint is not recognised, unlock the device using the pattern, PIN,
•
or password you set when registering the fingerprint, and then re-register your
fingerprints. If your pattern, PIN, or password is forgotten, you will not be able to
use the device if you do not reset it. Samsung is not responsible for any data loss
or inconvenience caused by forgotten unlock codes.
If you change the screen lock method to Swipe or None, which are not secure, all
•
of your biometric data will be deleted.
