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 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 recognized by the fingerprint sensor as the same fingerprint. For added security, set the screen lock using a Knock Code, pattern, PIN or Password. • If the device cannot detect your fingerprint, or you forget 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. • 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.
