Your phone sees your face like a detective. When you're close to the screen, it uses tiny cameras and sensors that work together like a team of detectives solving a mystery, they figure out where your face is and turn up the brightness just for you! It's kind of like how your mom turns on the lights when she walks into a dark room, automatically, without asking.
Examples
- It feels like your phone knows exactly when to adjust, just like a friend who always gets ready before coming to meet you.
- When you take a selfie, your phone notices you're near and makes sure the light is perfect.
