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 Gallery or QuickMemo +.
• Confirm a purchase by signing into an app or identifying yourself with
your fingerprint.
• You can use fingerprint data for user authentication. There is a
possibility that the fingerprint sensor might recognise a different but
very similar fingerprint as the same registered fingerprint. To strengthen
security, it is recommended that you use the pattern, PIN, or password
method for unlocking the screen.
• 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 maximise the recognition accuracy, check the following before
using the device.
• The device has a fingerprint sensor. Be careful not to scratch or
damage the fingerprint sensor with metal objects such as coins or
keys.
• If there are foreign substances (sweat, lotion, water, dirt, grease, etc.)
on the fingerprint sensor or on the finger to be put on the sensor,
fingerprint recognition may not work properly. Wipe the sensor and the
finger clean and remove all moisture before putting the finger on the
sensor.
