RootDim was formerly known as SuperDim. RootDim requires root privileges on your device. For unrooted devices, as well as for some devices incompatible with RootDim, try our ScreenDim.

RootDim lets you dim LCD screens (and a few OLED ones) to very low levels--lower than the OS normally allows (that's why you need root privileges)--to save night vision. This will be particularly useful for serious amateur astronomers.

On some devices you can also turn off LEDs (e.g., power LED).

If you have ChainFire3D, RootDim will let you conveniently control the nightmode settings together with the brightness settings.

You can save up to five profiles that can be restored with a single touch in the RootDim screen. The profiles include LCD backlight brightness and nightmode settings (if applicable). Long touch on profile button to save, short touch to load.

You can also create launcher shortcuts for particular saved profiles and for cycling through all the profiles.

If RootDim doesn't work on your device, email me at before leaving a low rating. Maybe I can fix it.

Note 1: Some devices don't allow going below the minimum value allowed by the OS. There is really nothing I can do about that.

Note 2: There is a special feature for some Archos 70/101 devices that have a firmware problem that prevents them from waking up properly when they've been put to sleep with a low brightness (this problem occurs even if you don't have SuperDim). Go to Menu|Options and choose that option if you have one of these devices, and it should fix the problem.

Note 3: For all the users who would like a widget, please remember the launcher shortcut feature.

    I've used other dimmers like Screen Filter, etc, but none of those apps would dim the softkey buttons at the bottom of my screen. It drove me insane! This app, however, dims those button lights (in addition to the rest of the screen). Why on earth one would need root privileges to dim those d*#mn softkey buttons is anyone's guess!! Thanks devz!!

    i was looking for an app that would allow me to keep the screen brightness all the way up to 100% when i reach a level of 5% on my battery, (i have a zero lemmon 7500 mah for my gs4 from cricket that's why) well this app did the trick all i had to do was give it root permissions and then whenever i'm on 5% battery or below i have to open this app move the slider all the way up to the max and it
