Keep Screen On & Dimmer Screen

Keep Screen On & Dimmer Screen brightness will help you do two those things in zero tap! Just open the app, your phone screen will be on forever and your phone screen brightness will down to zero too! Lower your phone screen brightness is an impressive feature of this app because most of us want to keep screen on and lower phone screen brightness together. Timeout to turn off is also a good feature! This app is useful when you want to keep screen on while uploading video to YouTube, downloading big file or for developer who want to keep screen on! Thank you!
