How Does Redmi note 8 double tap Display light on off Work?

The Redmi Note 8 uses double tap on the screen to turn the display light on or off like a friendly switch you can use with your finger.

Imagine your phone's screen is like a lamp in your room. When it’s dark, you want the lamp (or phone screen) to be bright so you can see. But when it’s light outside, you don’t need it as much. That’s where double tap comes in, it works just like pressing the switch on a lamp twice.

When you tap the screen once, nothing happens. But if you tap it again quickly, it’s like telling your phone: "Hey, I want to change the light!" If the screen was off, it turns on, and if it was on, it turns off.

It's just like when you press a button twice in a row on a toy or a game. The first time doesn’t do anything, but the second time makes something happen, like making your favorite character jump or a light switch flip.

This feature is super handy because you don’t have to search for buttons or swipe through menus, just tap twice and it does what you want! Like having a secret way to turn your phone's light on or off with just your finger.
