Face recognition
Face recognition overview
You can unlock the screen by using face recognition.
• This feature may be more vulnerable to security than the other screen
locks, such as a Pattern, PIN, and Password.
• When a similar face or a photo of your face is used, the screen may be
unlocked.
• The recognized facial data is securely stored in your device.
• If the device cannot detect your face, or you forgot the screen lock set
for your device, visit the nearest LG Customer Service Center 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 excessively
bright or dark conditions.
