Your phone has a tiny light sensor that works like a detective. When you go outside and it gets bright, the light sensor sees the change and tells your phone to make the screen brighter so you can still see what's on it, just like how you squint in the sun!
Examples
- If your phone is too dark inside, it knows to make it brighter in sunlight.
- The screen brightness changes automatically like magic when you walk from a room into the bright sun.
