My Space Grey S2 Sports have its aluminum "paint" flaking at the back and at the button. First touch with Apple via chat made it sound like they want to treat is as a "cosmetic damage" instead of manufacturing defect. Planning to go to an Apple store next month to see if I can get a second opinion. I'm finding many people have this issue, but mostly on S0. Any of you guys have this issue on your S2? And what would be your resolution?
