I discovered a couple of scratches on the screen of my iPhone 5 today which I found highly upsetting as I treat my phone like a baby going so far as to not even lay it down on a hard surface. This happened at about the same time I got my first real scuff so the double dose of QC shoddiness was too much for me to handle. I always thought the screen was supposed to be highly resistant to scratches even when scratched purposefully with a key or something? Is this a common problem? I'm pretty stumped as to where they came from as the only thing the screen has touched is a microfiber cloth and the insides of my pocket with nothing else in it. I did not inspect the screen out of the box. Any help would be appreciated.
