Was that if your phone is ringing at a bad time, like say you're in a meeting and forgot to put it on vibrate, if you place it face down, it will go silent. It works, yay!!! Now the question is, does anyone know how to turn that off? I searched and didn't see it. My phone is ALWAYS on vibrate. I just hate to hear mine, or anybody elses cell phone ring, don't know why. But I miss way too many calls as it is. My phone stays in my pocket and I don't want to take a chance of missing an important call cuz the phone some kinda way got flipped face down and it stopped vibrating.
