Precautions for using iris recognition
Before using the iris recognition feature, camera, and LED, keep the following precautions in
mind.
• To protect your eyes, keep the screen at least 20 cm away from your face when using iris
recognition.
• If you attach screen protectors (privacy protection films, tempered glass protectors, etc.),
the recognition may fail.
• Do not use iris recognition with infants. Doing so may damage their eyesight.
• Anyone who has experienced dizziness, seizures, loss of awareness, blackouts, or other
symptoms linked to an epileptic condition, or has a family history of such symptoms or
conditions, should consult a doctor before using iris recognition.
• The iris scanner is not intended for use as a medical device; biometric data collected
and stored locally by the iris scanner is not intended for any diagnostic, therapeutic, or
preventative medical purposes.
Alternative security options are available on your device. Please follow all the instructions for
the use of this feature.
For better iris recognition
The phone may not recognize your eyes when:
• Something prevents the camera from getting a good view of your irises (e.g., glasses,
glare, low eyelids, recent eye surgery, or a medical condition).
• The lighting is very different from when you recorded your irises (e.g., direct sunlight, or
much darker surroundings).
