I accidentally dropped my 7 on the floor this morning, only about 10 inches off a small table , and it landed on its screen, after picking it up I realised it had stopped working, screen blank no signs of life no matter what I did, I cursed a bit then went to find the box etc so maybe I could return it and get it fixed, when I thought I'd try one more time, I gently tapped 3 times on the screen as if to say "yoohoo you awake?" and when I pressed the power button bugger me it switched on!! It must have just been knocked out lol. Not sure why I'm posting this other than it made me chuckle. Dead...tap tap tap.....ITS ALIIIIIVVVE!!!
