Is your minimum screen brightness still too bright? Dim your screen below what your device normally permits for
comfortable use in darker environments, reading in bed, amateur astronomy, etc. Save battery life. No root required.
Save your five favorite brightness and contrast settings as a preset, and get it back by touching a single button or by a Launcher shortcut. ScreenDim also creates a notification item in your status bar so you can easily go back to it to adjust settings.
ScreenDim is the first dimmer that can both adjust backlight brightness below what the system normally permits on many LCD devices and dim the contrast. Some dimmers only lower the contrast, which keeps the black areas unchanged and glowing gray on LCD devices when in the dark, or only change the backlight within the range normally allowed by the OS.
ScreenDim was written and tested especially with the Kindle Fire in mind.
This is the full, paid version of this app. A trial version is also available for testing on your device.
To activate ScreenDim, just tap on the "Active" checkbox and adjust the sliders.
