Like the Galaxy S8, the Galaxy Note 8 features iris scanning as a more secure way to unlock your phone. It’s just as fast a method as the device’s facial recognition, but less vulnerable to spoofing. It’s also easy to set up.
Note: As on the Galaxy S8, you can’t use both facial recognition and iris scanning. Instead, you’ll have to pick your preferred method.
