Still... the amount of force necessary to bend that thing hardly falls within "normal use".
This sort of testing is as idiotic as the screen scratch test. Will it scratch? Sure, if you use the glass cutter or a diamond.
Will it bend? Sure, if you exert abusive amount of force to bend it.
Will it blend? Sure, if you put the phone in the blender.
Most consumers with normal IQ's will not do such a thing to their phones.
So, the guy doing the bending test must be an idiotic liar.
