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 the locked content in the 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.
• If the device cannot detect your fingerprint, or you forgot the value
specified for registration, visit the nearest LG Customer Service Centre
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.
• The device has a fingerprint sensor. Ensure that the fingerprint sensor
is not damaged by a metallic object, such as a coin or key.
• When water, dust or other foreign substances are on the fingerprint
sensor or your finger, the fingerprint registration or recognition may
not work. Clean and dry your finger before having the fingerprint
recognized.
• 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.
