Restrictions of the face recognition function

Restrictions on lighting conditions

Identification will not take place if there is not enough light. Do you have to work in the dark? Leave an alternative path: fingerprint, pin code.

Restrictions when using accessories

Extra accessories that hide your face can interfere with scanning. Before identification, remove hats, zero glasses, colored lenses. Leave only what you wear all the time.

Restrictions by face makeup

Girls, be vigilant! Overly bright makeup that radically changes the appearance will definitely prevent the first scan. Your smartphone may not be available if there is no other way to unlock it.
