I am the first to admit that iPhone will bend when enough force is used. Its made out of metal and it is thin.
But the way its being demonstrated in the video you can clearly see, where his fingers are etc.
If he tried bending galaxy note similarly, he would get the same result.
The metal band around galaxy would help a little but it too would show the same result.
So stop trying to bend your phones and start using them. Phone are not meant to be bent.
