Fingerprint recognition
Fingerprint recognition overview
You must register your fingerprint on your device first before using
the fingerprint recognition function.
You can use the fingerprint recognition function in the following
cases:
• To unlock the screen.
• To view the locked content in Gallery or QuickMemo+.
• Confirm a purchase by signing in to an app or identifying yourself
with your fingerprint.
• 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.
• The device’s Home key has a fingerprint sensor. Ensure that the
Home key is not damaged by a metallic object, such as coin or key.
• When water, dust or other foreign substance is on the Home key
or your finger, the fingerprint registration or recognition may not
work. Clean and dry your finger before using the fingerprint sensor.
• A fingerprint may not be recognized properly if the surface of your
finger has a scar or is not smooth due to being soaked in water.
• 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 Home key.
