Description
RootDim was formerly known as SuperDim. RootDim requires root privileges on your device.

RootDim has been largely superceded by our ScreenDim, which does not require root (though it also has an enhanced root mode, which on some newer devices may work more reliably than RootDim) and has useful features like presets in the notification area.

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 arpruss@gmail.com 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.

Comments on RootDim [root] for Android

★★★★★ Perfect. Dims the backlight to hardware minimums, beyond software minimums, and doesnt just use a black overlay. Cant find any other app tjat does this. Thank you so much devs!
★★★★★ This app definitely works!! It even brings down the brightness to almost complete darkness! I thank the developers for making this. It's a good thing that I have a rooted device, because this definitely would not work if it was a non-rooted ine. Thanks for making this app, devs!!!
★★★★★ Works perfectly i realize the benefits of root . It is extremely lightweight and simple ui. At least it is not just dark filter on screen really dim the screen. I recommend you to make similar app for phone's backlight dim. But some times app is fail to dim the screen. You should add a emergency button like long press volume button for 25% brightness because its lock feature make some difficulties on lighter environment.
★★☆☆☆ Granting root, should give an access to each RGB light scheme modification, but this apps asking for root permission just like normal swiitch to reduce the brightness same as the in the settings... So why ask root permission??? Its should goes to control the power delivery to lcd light to shine more less or Dim the light... This apps is no doffrent then other trash app
★★☆☆☆ Garbage
★★☆☆☆ Didn't work on my moto g5s
★★☆☆☆ Unable to adjust to lower brightness although be given root??? bug???
★★☆☆☆ Not working on ASUS ZenFone 2
