This video is great. The guy has the gist to make you watch the whole thing. However I managed to watch about 20 mins so far because it's too much information. So far he convinced me to use my full screen resolution because he said it doesn't consume battery life and the moment i switched my eyes felt the difference instantly and the screen has become easier on my eyes. Big plus. I also managed to change calls background so now I will have a cool image on my screen when someone calls me. 😊
