Mar 31, 2018 My phone screen keeps dimming. I'm not on auto brightness, nor on Low Power Mode. This seems to happen when I'm in the middle of a heavy use app, such as PUBG, the brightness would drop randomly. Then when I'd exit the app, and use the brightness scroller, it would have no effect on the brightness on the right half, it would stay constantly dim.
Meanwhile, MS Paint doesn't have enough features. 
My drawings are extremely simple and I do not need a lot of special effects, such as layers, lightning effects etc.Can anyone suggest a free software?
