NOTE Your fingerprint can be used by the device for user identification. Very similar fingerprints
from different users may be recognized by the fingerprint sensor as the same fingerprint.
Precautions for fingerprint recognition
Fingerprint recognition accuracy may decrease due to a number of reasons.
To maximize the recognition accuracy, check the following before using the
device.
At the bottom center of the product’s screen, there is a built-in sensor
that recognizes fingerprints. Be careful not to scratch or damage the
fingerprint sensor with metal objects such as coins or keys.
If you replace the protective film on the product with a polarized film that
diffuses the light or a film that is too thick, it may decrease the fingerprint
recognition rate.
If there are foreign substances (sweat, lotion, water, dirt, grease, etc.) on
the fingerprint sensor or on the finger to be put on the sensor, fingerprint
recognition may not work properly. Wipe the sensor and the finger clean
and remove all moisture before putting the finger on the sensor.
If the finger’s surface is rough due to it being scarred or pruney from
water, the sensor may not be able to recognize the fingerprint. In such a
case, register another finger’s fingerprint.
If you bend your finger or use the fingertip only, your fingerprint may not
be recognized. Make sure that your finger covers the entire surface of
the fingerprint sensor.
Scan only one finger for each registration. Scanning more than one finger
may affect fingerprint registration and recognition.
The device may generate static electricity if the surrounding air is dry.
If the surrounding air is dry, avoid scanning fingerprints, or touch a
metallic object such as a coin or a key before scanning fingerprints to
remove static electricity.
