Plastic backing is not the only issue. I have a hard case (Speck) about an 1/8" thick with a fairly large cutout for the back camera and flash on my 4g. However, with the case on, I get washed out flash photos. If I remove the case, the photos are fine and clear. This really ***, because it's a very good case and I don't want to go without the protection. It is a tight fitting case that is not easily removed for a fast flash photo. So I guess I'm screwed. A focused flash would probably solve it, I'm getting the same effect with video, too.
