Works Sometimes, get YAAB instead . Works, then brightness turns back on and I'll have to go to program again and stop and start it. Then after a few minutes the same thing happens. Annoying and useless when you cannot trust it to do its 'single' task it was designed to do. Uninstalled and installed Yet Another Auto Brightness which works 100% of the time.
Incorrect description This only works for amoled screens where each pixel emits light and is a standalone diode. LCD works by "passing" the light from the diodes behind the screen through layers of liquid crystal, which only paint the light from behind, and do not emit any. The only way of preserving battery on LCDs is decreasing the intensity of the backlight, and every phone has a built-in option for that.
Misleading description Only OLED devices will benefit from this app, as the older LED, LCD, IPS, etc. displays have uniform backlighting, the pixels only color the backlight, but the power output is the same either when bright or dark. Simpler power saving if you set the display brightness darker in setup menu which actually lowers the lighting power.
Ignorant dev This app, unless it sets parts of the screen to completely black, will not do anything. OLED still uses power unless the pixel is turned OFF ie. BLACK. Not darker. Also, will do a absolutely nothing for normal LCDs.
Turns the screen completely black Unusable. It's impossible to set it for a low intensity. The screen is completely blacked out no matter what the settings are. And it slows my system down to the point where it seems unresponsive
Useless As far as I can tell all the app does is reduce brightness, also last time it was updated was August 2014. So I'm pretty certain it doesn't hibernate apps or kill app processes. Waste of my time
