Face Recognition
Face recognition overview
You can unlock the screen by using face recognition.
• For stronger security, it is advisable to use Pattern, PIN, or Password.
• Unless Advanced face recognition option is applied, a similar face or
photo of your face may unlock your device. See Enhancing the face
recognition for details.
• 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.
