Does anyone else have this problem? Sometimes when I'm operating my 128GB iPhone 6S (Rose Gold) with one hand, i shift it down so that my thumb rests at the bottom of the phone. However, this causes a pretty significant amount of pain because the lightning port is so fricken sharp. It doesn't draw blood, but its extremely uncomfortable and seems like a really poor design choice. Anyone have any suggestions? I was thinking of buying some kind of rubber stopper to stick into the port when its not in use.
