I brought a samsung galaxy s 4g, but the issue seems to exist in other galaxy phone too. Today when I use my camera, I notice there's yellow shadow in the center (same for both photo and video taking) I searched online and found some galaxy phone user has the same problem. Some has yellow shadow in the center, some has pink shadow. I also notice the problem exist more than a year. (and samsung has didn't fix it ?? ) What can I do ? I brought my phone more than two weeks, so I don't know if my service provider (or samsung? ) will still fix or exchange for me. I dunno why I don't have the problem before but until now.
