I just tried it out with a 3GS and my iPhone 4. Looks like the 3GS does not have this problem. Or at least mine doesn't...
Got a tip for us?

Might just be me but I can see a slight green spot but it isn't noticeable because of the brightness. Hang on...
There we go:
See it?

I never noticed it on my 3GS either but the post after yours makes me think that perhaps the exposure level hid the spot.
I'll have to look for pics taken under cfl.
Another factor may be the greater dynamic range of the 4 camera revealing something that has always been there.
The exposure level definitely masked the issue. I cranked up the contrast on the image that he took above and there's the green spot.
Now I'm going to look through my point and shoot's images and crank up the contrast.
Did some testing and it seems to show up under every condition but CFL is the worse. Daylight and others it is very very faint (not enough to really notice)
My 3GS seems to suffer the same problem. I think all of these phones are going to show the green light under CFL. Some might be worse than others but I have yet to see a CFL shot that totally eliminates the problem.

Got my replacement today. Came out of the mystery black box. I don't care if it's refurbished or whatever. It is in perfect condition and still had the plastic on it. Happy to report no dead pixels on this phone. The white balance issues I was having? Well see for yourself. This pic (thanks to my dog Doug) was taken in almost complete darkness. I'm VERY happy with my new phone.
Those people who posted pics of 3Gs pictures showing the blue/green spot -- I am just curious, are you using iOS 4?
I wonder if the new iOS is part of the problem.

That's not a test or the green blob or uneven white balance. You are using the built in flash! The camera knows the white balance of the flash and the duration of the flash is long enough to to eliminate any blob issues. Any camera will have a problem with florescent lighting if you don't take control. My professional Canon camera will have similar problems if I don't control the variables like shutter speed, lighting, and white balance.
This problem can occur on all cameras!! Fluorescent lighting pulses 120 times per second changing intensity and color temperature. Taking a picture under those conditions is a challenge for the best photographer especially with a fully automatic camera like a cellphone.

Could you please explain how the flickering causes the blob to always be in the middle. No one can seem to explain it other than just saying "its the 120 Hz cycling". So if it is just a matter of control, could a photogrpher change the settings of their camera to replicate a circular green blob in the middle of their photo with a DSLR.
Mine doesn't have a green coating (just clear) but have a strange green tint on the right side - not center. Even on a natural lighting.
The green coating is actually an anti reflection coating, which reduces reflection from light incident from the front and often reflects light from an angle different for different colors. You may be thinking of a green filter which only allows green light through, but since the green is reflected light, it would reduce the amount of light in the photo if anything.
I've been following the green blob thing, and you're the first to say it's in natural light and off to the side, all the others I've seen are fluorescent and center. Could be your green tint is some other cause.

When JOBS uttered the camera comparison of that being a Leica, he was absolutely correct! Because this green tint is like Leica's M8 camera with infrared problems! The solution was to use IR filters.. guess what this cannot be done with iphone 4. So the Leica M9 came out... and I expect to see iPhone 4GS! soon enough.
Very disappointed.

Posted this on another thread, but I'm gonna post this here to hopefully get some more feedback:
Just thought I'd add my experience. I bought my iPhone 4 16gb a week ago. I noticed this week the green spot on pictures under fluorescent lighting. I've been able to compare photos of the same subject taken in CFL/flourescent lighting and then in natural lighting/incandescent. The issue is only there with the CFL/fluorescent lighting.
I've been reading tons of threads here and other forums about this issue and am considering exchanging my unit, but I am really nervous about getting one with other issues.
My biggest complaint about this, is my house is 90% CFL lighting and the pictures taken in this lighting are useless. In addition, I've been able to confirm that the same green spot shows up on the VIDEO CAMERA as well, so all my videos taken in my house or this lighting will have the same coloring issues.
I just can't accept this as "normal" for any type of camera. I've compared pictures taken with my 3GS in my house with the 4 and the 3GS has WAY better coloring and NO green spot.
Count me as frustrated.
I'd like to see pictures taken with an iPhone 4 under CFL or fluorescent lighting that DO NOT have any green spots to it. To date though, I haven't seen any, on any of the forums. I've read people who've said they exchanged their phone and the problem was resolved, but I've yet to see proof. I don't want to exchange my phone if the new one's going to be the same.
So...have any of you exchanged your iPhone 4 for the green spot issue and received one that doesn't have any green spots? Can you please link photo proof???

I still have the issue in CFL - but it's a LOT less than my first two phones where it was really completely unacceptable. Not that it's acceptable now - but on the first two phones both the front and rear had other color calibration issues.
The one I have now has the issue - as do all of them I believe - but not in excess. What is excess? I'm not sure what the threshold is But my pictures were very yellow regardless of CFL - and when in CFL - had very very green spots. And the light meter was wacky.
Now - as I said - it's all "tolerable"

How did you guys get apple to replace the phone because the apple store I went to denied my request but then again probably because I'm in Canada? Anyhow they did replace mine due to another hardware issue they found.
Dang nabbit,...I have the green tints too!
Just happened out of no where. Didn't have any imperfections before last night at work.

mine had this as well. i went to the genius bar a few weeks ago and while i was there they tried a few other phones belonging to some of the employees - all had the same issue. the genius told me i could have a new one anyway if i wanted, so i got a new one but it still has the same issue. i think this issue is inherent even with other cameras/camera phones when the photo is taken under cfl lighting.
Also,
I have a feeling that this phenomenon is caused by direct exposure to CFL lights, or LCD monitors. Why do I feel that this is the issue?
- Ive had my iPhone 4 in ALL lighting conditions without error. Lastnight at work, I took a photo with my iPhone 4 of an image that was on my computer screen. (LCD). After that, this is when I noticed the discoloration.
Furthermore, I asked my fellow employee if his iPhone had this discoloration, and at the time, it was VERY slight, only someone with wick'd eyes would notice. Then, he pointed his rear camera towards the CFL lights for a mere 2 (possibly 3 or 4) seconds, then placed the view point on the same spot where my camera would show the green, and his then showed the green with much more intensity then previously done, hence why I feel that the CFL lights, LCD monitor Lights are causing this.
Maybe this is a far fetched theory, but it's a theory nonetheless.
Hey guys,
So are Apple giving replacements for this green spot problem or is it classed as a normal problem? I recently had my iPhone 4 replaced due to dead pixels on the screen, and this phone didn't have the green spot problem, however my replacement has the problem. Cheers guys
