For better iris recognition
The phone may not recognise your irises if:
• s omething prevents the camera from getting a good view of your irises (e.g. glasses,
glare, low eyelids, recent eye surgery, or a medical condition).
• s omething gets in the way of the camera or the LED (e.g. a screen protector, dirt, damage
to the camera).
• t he lighting is very different from when you recorded your irises (e.g., too bright room).
• t he phone is tilted too much or is moving.
