Imagine your phone has a little eye that can see when you're looking at it. This eye is made of tiny cameras and special lights inside the phone. When you look at the screen, these sensors work together to tell if your face is close enough, like magic! It’s how your phone knows to wake up or turn on the light when you’re nearby.
Examples
- Your phone lights up when you look at it, like a little robot watching you.
- You're holding your phone close to your face, and suddenly the screen turns on, just because it saw you.
- Your hand covers the screen, and your phone knows not to turn on.
