The iPhone 4 has never been lauded for the durability of its glass panels. The iPhone 4S is no different. While the chemically-strengthened front screen could survive a tumble from waist and shoulder level, the back panel shattered instantly. And when dropped face down from waist level, the front screen exploded into pieces.
As for the Galaxy S II, it held up remarkably well. The plastic case took plenty of abuse, cracking and popping open. But the Gorilla Glass screen? Never shattered. Not even when dropped face down. So you know, if you have clumsy hands, maybe this vid will influence which phone you buy next. [SquareTrade]
