The 2nd vid does mamange to crack it. The first people are saying it is probably fake. But i have doubts on that. But it was on a rubber/vinyl tile floor. For laughs make sure to watch the video link another poster posted that is between the first and 2nd embedded vid
I have never seen a phone not made to be rugged take hits like that. In the youtube vid he did break it after dropping it from above his head on its face and back. Total drops 8.
