I've had my Gold i6 for about a week, and I noticed a couple days after I unboxed it that there were some weird black marks at the very edge of the screen were the white part meets the gold backing. They looked like scuffs, and I was disappointed because I bought the phone brand new, but it was in a case anyway and they were pretty small so I dismissed it. But today I got a baby wipe and wiped the scuffs with the wipe over my fingernail and they came right out! Like it was dirt or something. I'm wondering if anyone's experienced the same thing. I'm a little worried about how the marks got there; if there's a little gap between the screen and the aluminum backing big enough for things like dust to get in. This was the case with my old phone and dust was able to get into the front camera and ruin it very easily.
