Read this on another forum, has someone seen this "LCD shadowing" problem that the are referring to?
"I rolled into an Apple Store today to add apple care to my 6, and was politely refused. The reason? Turns out some of the units shipped with "lcd shadowing" around the area of the power button. Sure enough, on a solid white screen there was what looked liked a faint shadow. One the guy pointed it out it became very noticeable. I was told to take the phone back to Verizon to exchange."
