Ok, so let's put a phone in a vise and apply pressure to the middle until it breaks? Almost anything will break if it's put in a vise and continuously increasing pressure is applied to the middle. If they wanted to do a realistic test that displays what happens when the phone is placed in a back pocket and sat on, have a girl with a big round butt put the phone in her back pocket and then sit on it multiple times. Of course the phone will bend, but that would at least be a realistic test that shows what happens when an idiot puts the phone in their back pocket and sits on it. Anyone who puts the phone in their back pocket then sits on it deserves for their phone to bend.
