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. To enhance the device

security, set the screen lock to a pattern, PIN or password.

Fingerprint recognition accuracy may decrease due to a number of

reasons. To maximise the recognition accuracy, check the following before
