This is the 100th app on the market, and it's simple and low-power. It uses the screen as the light source.

It has a very simple interface, just a single button to start or stop the torch, with a very intuitive design.

This is the perfect app for people who don't have a flash LED (like Samsung Galaxy S), as it uses the display as the light source.

The screen dims when the torch is on, and increases back to 100% when the torch is off.

It is a system permission, so I chose not to introduce it in the app.

In some particular cases, the auto dimmer can slightly lower the screen brightness.
