Doesn't go below factory settings I'm on Android 5.1 and it doesn't go darker than what my phone can already go to. The contrast is helpful though.
Just right My Nexus 4 won't dim far enough at night. This does the trick. Got my monies worth :)
It really works I have used Screendim Full more than three years, on many devices. The app is very simple and powerful. Many presets and easy customisation make it handy. One time I had some questions and got a well explained answer from the developer.
Just got the right app for my flare.thanks
Absolutely fantastic Why this ability is not a core feature of android I do not know. One suggestion, perhaps there should be an option to turn off screendim by shaking the phone. So many times I've gone outside into the sun forgetting to brighten the screen and can't even unlock my phone let alone see enough to turn off screendim, forcing me on numerous occasions to turn my phone off and on again.
Update Download SELinix Modifier before it gets banned! It fixes the new root issue

1.56: Hi-res icon
1.55: Update interface

Listen to audio through your phone's earpiece when you earphones aren't handy.
Completely change screen colors (red on black night vision mode, set gamma, etc)
