Hey guys -
So I was messing around with my camera in my room the other day and noticed a very, very obvious green blob in the middle. I did some research and found out its common among phones, and only occurs in rooms with florescent lighting.
Well i do have florescent lighting.
I went outside and couldn't see the blob anymore.

Should I exchange it, or is this with every single phone?


Thanks


Josh

True, but is this common among all iPhone 4's in rooms with florescent lightings? if so, me exchanging my phone would be a waste of time.

Any advise anybody??

In an earlier thread other people posted that exchanging iPhones resolved the problem. But this was months ago so I don't know if they're still exchanging for this reason. If you try could you post back with the result? Cause I (and the other guy in this thread) have the problem, too, and it's really annoying but the nearest Apple store is pretty far from me.

Well, in my opinion, there's no need to exchange it. It will cost a lot of money. If you don't need to take photo often, just take phone outside. If you really need to take photo indoor, you can buy a camera. The camera can put indoor, it is reallyconvenient to use. I think, the cost of camera and a new phone will be nearly equal. And it has deceased a risk that if the new also has the problem.

I just bought my phone so I still can swap it using AppleCare.
So it Wont cost me a lot of money.

I do intend on using the camera often but like I said the green blob only happens on floresent lighting. I've taken pictures outside and not had the issue. The only place that I'll take pictures in with florescent lighting is my house, otherwise I don't see it being an issue.

That said if this problem is not among all iPhone I'll exchange it.

Thoughts??
 
What you are seeing is the anti-reflective coating that the lens is coated with. AR coatings work very well in natural light but, generally artificial light is terrible with AR coatings. It is because of the Thin-Film Interference Phenomenon. http://en.wikipedia.org/wiki/Thin-film_interference

Also the fact that the lens itself is not recessed like the 3G, exaggerates the problem. Most phones that have AR coatings on the lenses have similar/same problems. For example the HTC HD2 had a "pink spot" http://forum.xda-developers.com/archive/index.php/t-660356.html

A phone should work to best of it's ability. If OPs camera is not performing up to spec, it should be replaced. The only question is whether or not this is a problem with his phone or the tech Apple chose.
From what I have read, the issue is the type of camera, so while it's fair to ask Apple about it, a new handset may not address the problem.

Well all phones that have an AR coating on their lenses (which yes, is most smartphones). You can normally see it if you tilt your phone a little in flouescent light while looking at the back lens. Youll see a distinct "green/bluish" shade to the glass on the lens.

oh sorry, typo. I meant this is the same with all iPhones* so it wouldn't be worth swapping?
 
Yes, get it replaced.

I had an odd issue with mine that seems to be very rare. It was the only issue I had with my iPhone. And while getting mine replaced we went through two new iPhones at my local BB where I got mine. All of them had the green blob in the middle. I finally got a good one at the Apple store.

It's a bit of a hassle to take the time out of your day to go do all this but lets face it. You paid money for a perfect product and you shouldn't settle for a screwed up feature in your phone. Not to mention how wonderful it is to have a working one with no issues at all.


On a side note. Who made this custom camera for Apple? Because the camera is almost a bigger issue than the antenna.

I have that same problem, and I kept mind. I don't feel like it's a big enough issue for me to exchange it. And also, if you do exchange it, chances are, the new iPhone you're gonna get is gonna have the same problem.
 
the green spot isnt even an issue of a defective phone. stop being so OCD about it.
 
Does anybody have an iPhone 4 that doesn't have any blob issues in middle under fluorescent lighting?

Total waste of time if you exchange your iP4. All iP4s will get that artifact.

Try using the flash when shooting under florescent lights.
 
Change the lighting and not the phone. Fluorescent lighting will cause problems with any camera. It's even worse with a simple automatic camera like an iPhone that you have almost no control over. The basic problem is that fluorescent lighting isn't steady. It's flickering during the shot! Add daylight, flash, incandescent or any steady light to improve the picture. :D
 
Final word

So, does this affect all iPhone 4s?

I would prefer not to replace, as mine is 2 days old. The green blob is very bad in flourescent light though.
