I'm guessing you do. Using the gray background at 20% test, no one's been able to post a pic that doesn't show a discoloration on the left side. When I first read this thread I would have sworn I didn't have it. I really couldn't (still can't) see it with the naked eye. But when I took a picture of the phone I saw it.
In the pics I just posted using apps someone said they saw the issue with I can't see it (can anyone else?). So I guess the real question is what does it mean in everyday usage under normal conditions?
Are you saying that in your case you can't see it with the naked eye but only with a camera?
