What are you using it for, driving nails? I had many smartphones in over a decade and never a single scratch on a screen, without using any screen protector.
The X was just bad for tiny scratches. Mine had a bunch and it was stored in my pocket without anything else in the pocket to scratch it. It was the only phone I had that scratched like this.
This seems like the inevitable outcome of the equation of gigantic phones and key fobs while wearing skinny jeans.
yeah, if you put your phone in a pocket together with you key fob then that's not so different from using it to drive nails :) Fortunately, even skinny jeans usually have more than one pocket.
