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 by the device for user identification. Very

similar fingerprints from different users may be recognized by the

fingerprint sensor as the same fingerprint. For added security, set the

screen lock using a pattern, PIN or Password.

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

specified for registration, contact the LG Authorized 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.

• 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.

Custom-designed Features 7

• 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 coin or key, to remove static electricity before

scanning fingerprints.
