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.
