Brightness Adjuster

★★★★★ I require the ability to very precisely (in steps of 1%) adjust my screen brightness, since I am often using my device in complete darkness. The brightness slider in Android quick settings is simply not precise enough. This app does exactly what I require. 👍

★★★★★ Excellent, almost perfect. This is close enough to what I was looking for, a widget with 1 press to adjust brightness. The only thing that would be better is if there was a toggle button, so 1 tap sets to 0, another tap on the same button sets to 100. But it's fine, I really just wanted the 0 button most of all. Update: weird problem. With darkness filter on, I can't press the installation button for other Google play apps. Filter off lets me press the button now.

★★☆☆☆ Inaccurate. I set this to 30, but system reports 41.

★★☆☆☆ I'd give a rating of zero stars if I could cuz this damned "app" doesn't make a freaking difference for the "brightness" of which it's the same adjustment as in the original settings app.

★★☆☆☆ Only change the system brightness not lower
