Using only a Belkin Vue case. If I take it off, the circle is not as bad but still there.
I didn't think I fell into this but I guess I do. Took a picture of a white wall without flash.
To me it seems like a white balancing thing. On my first iphone 4 I remembered seeing the green hue right before the flash fired, like to counteract the flash throwing off the tint of the picture?
Might be a software problem if that's the case?
