Fingerprint Recognition - Samsung SM-A145M User Manual

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 recognize them as
identical.
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 recognized, 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.
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 device may not recognize fingerprints that are affected by wrinkles or scars.
•
The device may not recognize fingerprints from small or thin fingers.
•
To improve recognition performance, register the fingerprints of the fingers used
•
most often to perform tasks on the device.
The Side key has a built-in fingerprint recognition sensor. Ensure that the fingerprint
•
recognition sensor is not scratched or damaged by metal objects, such as coins, keys,
and necklaces.
Covering the fingerprint recognition sensor with accessories, such as stickers, may
•
decrease the fingerprint recognition rate.
