Some friends who have iPhone 4 found that the camera has a defect leaving a green mark (blurred) in the center of the image, I tried hitting a picture of a white wall and really have this problem too.
Anyone else have this? Do a test, hit a shot with the light background.
Adding an important analysis:
1) The problem also occurs in the filming;
2) The spot appears only when it is under fluorescent light, yellow light in the sunlight and the problem does not occur;
3) The spot enlarges as one zooms in photo / film therefore is not hardware problem but software as the zoom is digital;
4) For some stains can be "yellow"or "orange", in my case "greenish. "
The big debate is on Apple's forum:

Therefore, I expect the iOS4.3 to see if the problem continues.
