People with glass phones shouldn't throw stones
and yeah its glass so its going to break.
BTW, the iPhone 4, 4S, 5, 5S is just as easily broken with glass backs and lets not get into the 5C which was the biggest piece of crap that apple ever put out, "Unapologetically Plastic" is what they said after years of trashing Samsung for plastic phones.
My co-worker dropped his 4S (work phone) I gave him a screen protector to hold the back together and then a firm case to put it into (wasn't using it anymore) so he could get by.
