iPhone 4's camera with blue tint issue

it seems to be a widely noted issue. mine has it too, but i only noticed it when someone told me about it. it affects the rear lens and not the front lens for my case. even when i am just in the camera viewing mode, the blue tint is obvious. i understand it happens only under flourescent lighting.

I had this problem and it went away when I got a different iPhone case. I turned out my old (blue) case was slightly covering an edge of the camera lens.

I am having the same problem and it's occurring under many different lightings, not just fluorescent. Today I took picture outside under normal overcast daylight and the whole thing has crazy blue shades. It's incredibly aggravating and I have no idea how to fix it. (My case doesn't interfere with my lens, and I had never had this problem until recently - I am pretty sure it coincided with a software patch).

Anybody have any ideas what is going on?

I have the same issue too. Only realized it today when taking a photo with white bkgrd.

I'm still on iOS4.1 thou...

I'm going to the Genius Bar today. I have a replacement iPhone 4. The camera on my first one was flawless. I took a series of photos with my new iPhone and noticed that blue haze in the center. At first I thought it was just me.

I went to the Genius Bar today. Results were mixed. They definitely noticed the bluish blob when I pointed it out. They were about to swap out my iPhone with a refurb. The Genius tested the new iPhone before he gave it to me -- and it was worse. The blue blob was much more pronounced. So he tried another iPhone. It had a greenish blob. He took the back off of it to see if there was a film on the lens cover, but it was clear. He brought in another Genius who had a 1st generation iPhone 4. Interestingly, the image from that camera was perfect. Yet another Genius was brought in. They ended up checking 10 iPhones. All but that first gen iPhone 4 had the problem to differing degrees. (Mine ironically was one of the better ones.) The third Genius said, "Oh well, I guess that's the way the camera is. Remember it's just a phone." I emphasized that it's a really expensive phone and that my first gen model didn't have this problem. His response: "You can probably correct the problem with image editing software." I replied that there shouldn't be a problem in the first place.

The upshot of all this is that they're ordering a replacement camera for my iPhone, which should be in next week. We'll see if that fixes the issue.

The Apple Store replaced the camera in my iPhone 4 today -- and nothing changed. I just saw the "discoloration" thread, and I think JKMarshall hit the nail on the head -- the discoloration might happen only under florescent lighting. I took a series of photos at a wedding under incandescent lights, and they came out perfect. But under bright florescent lights, that blue blob appears.

I agree with JKMarshall that a software update could potentially fix the issue.
