I had 2 iPhone X phones with a “slight bend” ... the only way I saw it was if I held the phone (out of case) on edge and looked down either edge. It’s very slight!! I now have and XS, same thing. I looked at an XS Max, same thing. I think it might be very common if not straight from the mold at the factory. Never sat on or dropped btw, fresh out of box Can anybody else confirm? Just curious, thanks!!
