Iris recognition on Galaxy S8
The Samsung Galaxy S8 features iris recognition technology which helps keep your phone safe and secure. This uses the iris recognition camera and LED to scan and recognise the unique pattern of your iris.
Precautions for Iris recognition
- To protect your eyes, do not stare at the iris recognition LED light when your eyes are less than 20 cm away from the device.
- Do not use a screen protector that may cover the proximity sensor. It may cause the proximity sensor to malfunction and thus the iris recognition LED may not turn on when you are close.
- Do not subject the device to excessive impacts or scratch the area around the iris recognition camera and LED with sharp or hard objects. Doing so may cause damage to the iris recognition camera or LED resulting in it to malfunction.
- Do not use iris recognition camera and LED with infants. Doing so may cause damage to their eyesight.
- Anyone who experiences dizziness, seizures, loss of awareness, blackouts, or a family history of such symptoms or conditions, should see a doctor before using iris recognition.
