What is the point of having a phone if you aren't going to use it to its all potential. For example, seeing the distance and and elevation gain when I ride a bike. Using it for that doesn't seem too outrageous to me.
It would have done that fine but you were sitting on it or somehow applied enough pressure to bend it.
Nothing wrong with the 7+ as these forums would light up with bend phone and that is not happening.
If you are very lucky, Apple will replace it, if not you could just bend it back.
