You can use the fingerprint recognition function in the following cases:

•To unlock the screen.

•To view the locked content in the Gallery.

•Confirm a purchase by signing into an app or identifying yourself with your 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, contact the LG Authorized Service Centre with your device and ID card.

Custom-designed Features

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 centre 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.

•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 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.

Custom-designed Features

3Follow the on-screen instructions.

•Until the fingerprint registration is completed, move the same finger around on the sensor little by little.

•Put the finger on the sensor. When you feel a vibration, remove the finger from the sensor.

4When the fingerprint registration is done, tap OK.
