For better fingerprint recognition
When you scan your fingerprints on the device, be aware of the following conditions that
may affect the features 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 fingerprints of the hand used most often to
perform tasks on the device.
The fingerprint recognition sensor recognizes fingerprints. 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 protective films, stickers, or other
accessories may decrease the fingerprint recognition rate. If the fingerprint recognition
sensor is initially covered with a protective film, remove it before using the fingerprint
recognition sensor.
Ensure that the fingerprint recognition sensor area at the bottom centre of the screen
and your fingers are clean and dry.
If you bend your finger or use a fingertip, the device may not recognize your fingerprints.
Make sure to cover the entire fingerprint recognition sensor with your finger.
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.
