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 Qu.
• 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 recognised 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 Authorised Service Centre with
your device and ID card.
