I'm in bed using my tablet. I turn its brightness right down. Next day, I go to the beach. I can't use my tablet, can't see a thing. I hopelessly/blindly try swiping down twice, or with two fingers, then stabbing where I think the brightness bar might be. I tried using my jacket to cover my head and tablet, didn't work. I could not use my tablet without going inside somewhere to be able to see just enough to turn the brightness up. Android itself should have something to deal with this problem. It doesn't it seems. But is there an app to fix it? Like, four taps on the screen or something (or some other simple not requiring any screen buttons method), to turn brightness up to full. Thanks.
