Smart Screen On for Android Turns Your Phone%u2019s Display On or Off When you Wave Your Hand Over It. Since my youth, when I first read the Arabian Nights, I have wanted to control my world with a wave of my hand. One of the annoying things about smartphones is that, to wake up the screen, you have to push the hardware on off button. Since I do it all day long, I worry about the wear and tear on the button. Why can't I turn off the screen, and then turn it on again, with a wave of my hand? The Nexus has a proximity sensor, doesn't it? Well, now I can with this little program, Smart Screen On. For a couple of bucks you can get the Pro version, which does a lot more. Android ingenuity strikes again.
