My 7 Plus Jet Black got a hideous scratch on the screen. Small, but still hideous. Oddly, there are no major scratches on the back which was supposed to be far more delicate. Like the OP, have no idea how it got there since it never went in a pocket with anything else but the lesson was tempered glass screen protector on day one of any new phone. Stuff happens so now I just try to be over protective. They're not impervious to damage.
