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 access locked contents in Gallery or QuickMemo+.

• Confirm a purchase by signing in to an app or identifying yourself with

your fingerprint.

• You can use fingerprint data for user authentication. There is a

possibility that the fingerprint sensor might recognize a different but very similar fingerprint as the same registered fingerprint. To strengthen security, it is recommended that you use the pattern, PIN, or password method for unlocking the screen.

• If the device cannot detect your fingerprint, or you forgot the value

specified for registration, visit the nearest LG Customer Service Center with your device and ID card.

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.

• At the bottom center of the product’s screen, there is a built-in sensor

that recognizes fingerprints. Be careful not to scratch or damage the fingerprint sensor with metal objects such as coins or keys.

• If there are foreign substances (sweat, lotion, water, dirt, grease, etc.)

on the fingerprint sensor or on the finger to be put on the sensor, fingerprint recognition may not work properly. Wipe the sensor and the finger clean and remove all moisture before putting the finger on the sensor.

Custom-designed Features 23

• If the finger’s surface is rough due to it being scarred or pruney from

water, the sensor may not be able to recognize the fingerprint. In such a case, register another finger’s fingerprint.

• 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.

• 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 a coin or a key before scanning fingerprints to remove static electricity.

Registering fingerprints

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

Tap Settings Lock screen & security Fingerprints.
