Brightness Setting is a free Android application developed by gigavitts that allows users to easily adjust the brightness of their device screen with just one touch. The app features a large button that switches between eight different brightness settings, including an automatic option.

One of the best things about this app is that users can set their preferred brightness levels in advance, making it even easier to adjust the screen brightness to their liking. However, it is important to note that for users with Android 6.0 or higher, the app requires permission to access the system setting in order to change the brightness setting of the terminal. This can be done easily by enabling "write permission of system setting" for the application, which will prompt users to do so upon first startup.

Overall, Brightness Setting is a simple and effective way to adjust the brightness of your device's screen, making it a great choice for anyone looking for a quick and easy solution to this common problem.
