It's amazing that people think nothing can happen to a phone. Years ago I sold phones. People wanted money back because they drowned a Nokia in the toilet. Or complained the device stopped working after they dropped it from a great hight. Nowadays people complain something will bend when you apply a lot of force to it.
It's not an unreasonable expectation seeing as a different phone of a similar form factor does not bend: https://www.youtube.com/watch?feature=player_embedded&v=FwM4...
Large and flat will bend, break or crack. It's just the nature of things.
