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 the 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 recognised by the fingerprint sensor as
the same fingerprint.
Precautions for fingerprint recognition
Fingerprint recognition accuracy may decrease due to a number of reasons. To
maximise the recognition accuracy, check the following before using the device.
•
The device' s Power/Lock key has a fingerprint sensor. Ensure that the Power/
Lock key is not damaged by a metallic object, such as coin or key.
•
When water, dust or other foreign substance is on the Power/Lock key or your
finger, the fingerprint registration or recognition may not work. Clean and dry
your finger before having the fingerprint recognised.
•
A fingerprint may not be recognised 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
recognised. Make sure that your finger covers the entire surface of the Power/
Lock key.
