Face Recognition
Face recognition overview
You can unlock the screen by using the saved facial data.
NOTES • 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 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%.

camera lens, or your device cannot detect your face due to an
exceedingly bright or dark condition.
