This makes it easy just to push
the invisible home button on the front of the Galaxy S8 (it's always on, even when there's nothing on the screen) to get to the home screen, or press the home button after quick - launching the camera without having to wait for the phone to unlock.
Because you can turn
on the Galaxy S8 by tapping
on the
invisible home button (Samsung's term, not mine) and have the phone automatically begin scanning for a face, the sequence, while not quite as fast as a
front - facing fingerprint sensor, is just as seamless, and when it works, it's a remarkable achievement.
