Face Recognition
Face Recognition overview
You can unlock the screen lock by using the saved facial data.
• This feature may be more vulnerable to security than the other screen
locks, such as Knock Code, Pattern, PIN, and Password.
• When a similar face or a photo of your face is used, the screen may be
unlocked.
• The recognised facial data is securely stored in your device.
• When the face recognition is selected for screen lock, you must enter
the Knock Code, Pattern, PIN, or Password that has been used for face
registration without directly using the face recognition after the power
is turned on. Accordingly, be careful not to forget the specified value.
• If the device cannot detect your face, or you forgot the value specified
for registration, visit the nearest LG Customer Service Centre with your
device and ID card.
• To save power, the Face Recognition feature will not work when the
battery level is below 5 %.
Precautions for Face Recognition
Face Recognition accuracy may decrease in the following cases. To
increase its accuracy, check the following before using the device.
• When your face is covered with a hat, eyeglasses, or mask, or your face
is significantly different due to heavy makeup or beard.
• When there are fingerprints or foreign substances on the front of the
camera lens, or your device cannot detect your face due to a too bright
or dark light.
