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 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 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 Home key.

• 

Scan only one finger for each registration. Scanning more than one 
finger may affect fingerprint registration and recognition.
