    Hi All,

    I'm on my third iPhone 4 with the green blob issue - When you point the camera against a white wall or bit of paper, there is a green blob on the screen.

    Is this an issue with all iPhone 4's?

    It's getting boring and ruining my photos

    My camera on the iPhone works wonderfully. I never even heard of this green blob issue.

    Open your camera app and point it to something white.

    Hmm, never noticed before. I just tried it out and sure enough, there is a green blob on mine too. Its most notable if I am taking a closeup shot. I'll post a pic here in a little bit.

    I wonder if this is a new bug with 4.3 or been here for a long time? I know I've never noticed it before.


    [edit] - Here's a pic I just took and uploaded to share. It's a white shop rag I had at work. Green blob is very noticable. Took pic from about 8-10 inches away from the rag.

    It's an issue with CFL (compact fluorescent lighting). Doesn't happen with incandescent or natural light. It's been there since the original iPhone 4 release.

    Is that with or without the flash?

    I took a picture of my white wall without the flash and I didn't notice any green hues.

    Maflyn, No flash.

    Is this CFL issue only affecting the iPhone? My Canon point and shoot doesn't have green blobbing.

    Its maflynn ;)

    since I didn't notice any green blob or hue when I tried it. What's the lighting Was it CFL (as noted in the other post), incandescent or sunlight.

    Sorry, I got fat fingers, lol.

    CFL here at work. I went outside and the problem went away, so definitely an issue with the lights in here. But at the same time, my canon doesn't get affected by the lighting so no green blobs. Pictures come out awesome on that camera.

    CFL, fluorescent lighting. My phone camera does this, too.

    No worries :)

    So its more likely because of lighting in conjunction with the phone. So back to the OP's question. It does seem to affect every phone and he shouldn't return the phone for another as it will also have the same issue.

    I went to the apple store to test their phones. The Verizon phones do not do this at all, but all of the at&t ones did.

    It can. You may not see it as green. Florescent lights flicker but are generally too fast for us to notice, but cameras pick them up when the shutter speed is higher then the frequency of the light. I run into this all the time when I have to shoot at my friends dance studio. They have florescent lighting and I need fast shutter speeds to catch the dancers in action so I have to bring my own lighting setup since if I use the overhead lights the image comes out with almost stripes down it.
