Simplest Screen Light + Dimmer

一个简单的基于屏幕的光带调光，你可以每天使用。

Simplest possible screen flashlight with brightness control for your Android device.

Right to the point: Just slide up your finger to make the screen light brighter, and slide down to make it darker.

It can be used outside during hiking and camping, during power outage, when you need some light when reading a book or when opening doors in the dark, etc. Even though it is a very simple application, there are many use for it.

App doesn't require any permissions, it doesn't have any annoying advertisements, and it is completely free.

Hope you will enjoy this app from http://simplyusefulapps.com

PS: Please note that, this is not using the device's back light but the screen's brightness to provide the light.
