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 locked contents in QuickMemo+.

•Confirm a purchase by signing in to an app or identifying yourself with your fingerprint.

• Your fingerprint can be used for user identification. Very similar fingerprints from different users may be recognized by the fingerprint sensor as the same fingerprint. To ensure security, set the screen lock using a pattern, PIN or Password.

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.

•Ensure that the fingerprint sensor is not damaged by a metallic object, such as coin or key.

•When water, dust or other foreign substance is on the fingerprint sensor 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 fingerprint sensor.

Custom-designed Features

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

•The device may generate static electricity if the surrounding air is dry. If the surrounding air is dry, avoid scanning fingerprints, or touch a metallic object, such as coin or key, to remove static electricity before scanning fingerprints.

Registering fingerprints

You can register and save your fingerprint on the device to use fingerprint identification.

1 Tap

Settings Lock screen & security Fingerprints.

Custom-designed Features

3Follow the on-screen instructions.

•Repeat scanning the fingerprint by moving your finger little by little until the fingerprint registers.

4When the fingerprint registration is done, tap OK.
