My iPhone 4 and my son's bought 3 weeks apart both are worthless using the flash at night. All of the images are blue. This is coming from someone my wife would describe as a Apple fanboy. I have tried taking images with and without the case to ensure that there is no glare from the edges of the case.
I hope Apple is working on a software fix for this problem and wish they would state they are but understand why they would not.
Latest iPhone 4 Serial Number list based on user feedback here:
Good Camera (proper white balance)
85028 <-my working replacement
Bad Camera (yellow/orange tint)
In Dispute (some say good, some say bad)
Other camera problems:
Halos, blue spots, or other discoloration issues
(ie. like this shot: http://www.flickr.com/photos/52186195@N08/with/4801257808/ )
I finally had my iphone exchanged today, at an apple store (Rome). A very kind girl acknowledged the issue (I had red and green areas on the pictures) and gave me a new phone. I checked and the issue was still there. She gave me another phone (the one I have now, series 86024). It has the "yellow white" and the light red stains in indoor pictures, with dust inside the camera. I didn't know what to do. I felt stupid, not sure whether asking for another swap or not. After an "apple worker" agreed with me about the problem being still there, I asked another technician at the store if she could see the colors issue on the picture. She said (resuming) "No, I can't see anything, I think the problem is your eyes being too demanding" and also "We can't do anything for you. There's no dust inside the camera". She checked again and... magic, the dust (or whatever it is) was actually there! But she still couldn't do anything. So, at the end of the story, the camera has no problem, it's just me. The antenna has nothing bad, it's me holding the phone the wrong way. The camera has no dust inside, it's my eyes, they are so creative! At least I hope yellow, red, blue and white will be adjusted with an upgrade. I just want an expensive smartphone to work properly, as advertised, and for a device that costs a bit less than 800€ I'm a bit deceived.
Just want to add that I am having the same issue of very yellow/orangish tint to indoor photos. It's like the software assumes the flash will auto-fire indoors, and since the LED flash is somewhat bluish, it tries to compensate. If the flash doesn't fire, the pictures are wrongly tinted. I compared to another digital camera, taking photos of white sheets of paper, and there is definitely inappropriate coloring.
Of course I've removed film. I've even removed back panel and disconnected/reconnected camera module since I had read on some site that the problem can be in bad contact. It didn't help. Since I can replace/repair iPhone (Apple doesn't provide warranty for them here in Russia) I've ordered spare camera. Hope this will help... It's funny that there is a lot sites selling other parts of iPhone 4, but only one selling cameras, for $20. Hope they in fact have them. It's a shame for Apple exclude Russian iPhones from warranty list (they support all other devices but phones) and save money on such cheap components...
I've tested to see whether the camera chooses a preset WB when the flash is used and it doesn't. It still uses Auto WB.
This might mean that a WB reading is taken at the time the pre-flash fires which is going to be relatively blue. Therefore any area that isn't exposed to the light from the flash will be very yellow in comparison. (Probably most of the room because the flash isn't that powerful)
When using a flash indoors, to balance the flash and the ambient lighting, you would normally add a tungsten filter to the flash (which I'll try this evening).
That way, the WB will be calculated using a warmer flash colour and the entire image will be more natural.
This might explain why using a flash indoors produces even warmer images than just using the indoor lighting.
I used this tool to see what the WB was
I REALLY wish Apple would make some sort of announcement on this issue.
My iPhone 4 back camera takes VERY yellow photos in artificial light (front camera OK).
I'm 90% convinced it's a software issue, and Apple will fix it.
But when people post messages like this:
"A friend's iphone 4 camera has no orange tint at all and the white balance of the LCD overall was accurate"
it makes me think it's a hardware fault and I should go back to the store for a replacement.
Other iPhone 4 users I've spoken to report yellow pics also. What should we all be doing?
Apple, please advise!
Here's the way I see it (and I could be wrong). I too bought four iPhone 4s for my family on day one. All four have the yellow pic white balance issue (although my sister swears hers is fine, I finally got a chance to check it this past weekend next to my working replacement and she has the issue! I didn't tell her though since she's happy ). I also believed that it was a software issue until someone pointed out AND posted SIDE-BY-SIDE comparison shots of iPhone 4 shots taken with two different iPhone 4s and one had the issue and the other didn't. My logic tells me that since all iPhone 4s are running the same software that this has to be some type of hardware glitch and that's the ONLY REASON that I went through the hassle of going for a replacement. Two replacements later (three if you count the one that I didn't take from the store because it too had the issue), I have one that does NOT have the issue.
Now with that said, I still do believe that this CAN be addressed with a software fix and here's why. Let's say there is a bad batch of iPhone 4s out there and Apple can identify the range of serial numbers (as I have attempted to do in my non-scientific way), then all they have to do is issue a fix that targets and adjusts the white balance for the iPhones in that range. That of course assumes that it is something that the firmware can adjust and not some malfunctioning sensor.
So your options are:
1) wait it out and hope that Apple addresses it one way or the other. It's not unheard of for a limited recall on a range of serial numbers. They do it all the time (bad Time Capsules was the most recent example).
2) go in for a replacement and either request a replacement in the range of serial numbers known to be good posted earlier in the thread OR create a lighting condition in the store (as I did) to see for yourself if it works or not before leaving.
I'm lucky that my Apple store is only 15 minutes away AND very accommodating. What I don't have time to do is go back and forth getting replacements that have the same issue.
Here's a recent post I did about getting a working replacement:
This issue seems to be very wide spread as most phones that I've encountered have this issue. The only reason I returned mine was when my friends phone clearly was fine with no yellowing. I walked around at my work with his in hand and my old one side by side. Natural light both phone produced the same color and white but as soon as I was under low soft lighting mine produced yellow/orange pics. I was glad to see the issue was not present on my friends phone but upset that with the same software mine seemed to be broken. So off I went to exchange an otherwise perfect phone. I requested a 79031 and got a 7s030 and the camera produces correct colors under soft lighting. Like Terry I still feel like this can be sorted out with a manual white balance rather than the phone using the auto white balance under artificial lighting.
