Touchscreens are nice. You slide, you point. Then there's motion sensors. You shake, you tilt. These are the things that are in smartphones these days. Some of them also have this little thing that I like so much.

See, having a touchscreen can be a nag. Let's skip about all the oil on the screen that leaves you wiping it more than using it. I'm talking about accidentally touching something with your face when you're making a phone. Well, not for phones with this feature. It will detect your oily face approaching and immediately shut off the screen. Feel free to smudge your cheek all over your nice and smart phone, it will not mistaken it for a command.

Nice little phone, good little phone.
