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 pattern, PIN or Password. • If the device cannot detect your fingerprint, or you forget the value specified for registration, visit the nearest 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. • 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 you replace the protective film on the product with a polarized film that diffuses the light or a film that is too thick, it may decrease the fingerprint recognition rate.
