iPhone 3G Yellow Screen Issue

I think this may have something to do with the "auto brightness" feature, my screen looks very yellow in low light conditions but if I'm out side or put all the lights on it goes bright white.

I'm pretty sure this is not just a trick of the light, in good light the whites really come out white.

Very strange

Again, comparing your 3G iPhone to a 2G iPhone is a poor comparison unless you can guarantee that the 2G version has a screen that's properly calibrated, and not simply too blue. Maybe it was too blue, people got used to it, and are now using it as the standard for comparison. This doesn't mean the 3G iPhone's screen isn't yellow. Judging from the photos, it obviously is a little bit more yellow. It's just that the degree of yellow may not be as severe as people are making it out to be. :)

Furthermore, ACCURATE white balance depends on the source of light. On a partly cloudy day, your slightly yellow screen is going to look perfectly white. Same thing happens in photography, except your photos end up more blue on a cloudy (or partly cloudy) day. Many fluorescent lights are a bit bluish, so the iPhone will look good there too. There is no perfect WB for an LCD screen in every situation.

In other words, your screen will look different based on the type of lighting you're using your iPhone in. That is why screen calibrators (e.g.:Spyder, GretagMacbeth ones) all suggest that you calibrate your LCD in the same lighting conditions you normally work in. With any LCD, the colour will vary depending on the temperature of the light that surrounds you.
 
Has anyone had a "not" yellow screen? Like a screen comparable to the 1g?

Man that is a deal killer for me. If I am going to be paying that much, I want something easy on the eyes.
 
i have two 3g iPhones here and they both have the yellow tint compared to the regular iPhone. I noticed even before I read this so it is apparent. Bought the phone from an AT&T store in North Miami.
 
Whatever the outcome, I'm just glad I've got all these people signing up to 18 month contracts to find the iPhone 3G's faults so I don't have to :D

Seriously though, having scanned through this thread, the few sensible suggestions I've seen are the ones which point out white balance is never going to be perfect; blue tinting is less likely to be noticed than yellow tinting, even if it is stronger and to cal call *3001#12345#* to see if it is actually a different LCD in the new iPhone to the previous generation.
 
My first 2.5G iPhone had the yellow tint issue.

Now, i have it again on my new 3G iphone, but i really don't mind because you cant tell its yellow unless its side by side with another iphone.
 
Don't Panic!!!

Wow... what a load of scare mongering... anyone holding off don't worry. I have both the 2G and 3G and Yes the whites on the 2G are bluer than those on the 3G...BUT the 3G does not have a yellow tint as such... the gamut is just set up differently on the 3G - slightly warmer and higher contrast...if anyone has ever run another monitor off their powerbook they will know what I mean.
Try getting the two to match!!!

I would not delcare this to be a fault as such, just different calibration which if it bothers enough people Apple could probably adjust on an update.

In truth using the 3G in isolation you don't notice it.

After the mess that has been Mobileme today, I think we all need to calm down, call someone we know, say hi... ask em how they are and use the damn thing for what it was built for!
 
The comments about white balance of the room etc making screens look different colours - but there's still no denying that the colours of two screens side by side look different, so the screens must be different. Right?

Since I was the one who mentioned about less useless speculation and more hard evidence.. here is some hard evidence:

I imported the picture into Photoshop, and check the actual colors. Now assuming that the digital camera used to take this picture has no color cast of its own:

The iPhone on the left has a blue bias, the iPhone on the right has a yellow bias. However, the left iPhone has MORE of a blue blas than the yellow bias on the right iPhone. So the right iPhone actually has a more accurete color.

But if you tend to prefer a bluish color, as if you are conditioned to the way the vast majority of computer monitors look leaving the factory nowadays, with color temperature around 9000K (way too blue as daylight is only 6500K), then you might consider the right iPhone as too yellow and the left iPhone to look more "correct".

QFT. The "problem" here is that the iPhone 3G looks different than the 2G iPhone does. Objectively looking, the 3G iPhone has screen that has more accurate colors than the 2G iPhone has, but people have gotten used to the screen on the 2G iPhone, with incorrect colors and all.

If the screen were reversed between 2G and 3G iPhones, we sould now have threads where people complain "the screen in my 3G iPhone has blue tint!"...
 
Spanky's Picture

Have a look again at Spanky's picture at the beginning of this thread. Look at the background to the left of the yellow-screened iPhone on the left, and now look at the background to the bluish-screened iPhone on the right. Note the background on the left is more yellow than the background on the right. You can even do a comparison of each bit of background using the cmd-shift-4 trick we heard about earlier.

I'm not suggesting the photo is a fake, but the contrast between the two screens might well be amplified by a photographic aberration. Spanky, is this exactly how it looks in real life? It seems to be more extreme than other comparisons.

Oh, and by the way, the folks at 9 to 5 Mac have already picked up on your pictures and this thread...
 
@owen-b: Yes, that's right. However, the screen models on the 2G iPhones also changed during its production, and so did the white balance, and yet I don't remember hearing this much about it. ;)

You can, but I think that really hardcore people (which I'm not) will turn on the lights they normally use while working (ceiling light, desk lamp, floor lamp, etc) to make sure the LCD is calibrated under the same conditions you work in. Some people even have multiple colour profiles for the same LCD.
 
Mine also has a yellow tint, but I'm not gonna bother getting it exchange since almost everybody is reporting this issue, and besides I don't want to risk returning it back and getting one with a dead pixel.
 
That first photo I posted is definitely what the difference was like, not a photographic anomaly. I'm lucky in that CPW managed to find another iPhone to replace it for me. I can't check to see if its any better yet because in the mean time the US iPhones went on sale and the activation server's crashed. I'll report back when I have it activated and will compare it again.

Wait a sec, you managed to get *two* iPhones out of the CPW today?!!! :eek:

I've had no end of trouble, my order from O2 placed on Monday at 8.30 is still showing 'In Progress'. After yet another call to them today, they're now more non-committal than ever, couldn't even guess at when they'd fulfil the order.

Tried queuing at the stores, but forget about it. They'd already sold out of 16GB by 9.15 this morning where I live.

Right now I'd take the yellow-screen over nothing at all!!! I bet they flog your old one to a desperado who's been queuing all day...
 
The screen has issues, no doubt about it. Just take a look at your photo album, the pics are not sharp they have a dull look.
 
More than a 'bit' yellow

I have two 1G iPhones side by side with the iPhone 3g, and the 3G is more than a 'bit' yellow. It is bordering on green. Very ugly. The black is not even close to black either.

It is hard to tell in these low quality photos, but it is VERY noticible. I thought I was dellusional and showed my girlfriend and she said, "it is duller, and less sharp, but brighter." UH!

The glass is mounted on a bit of a tilt as well, and you can feel this on the edges of the screen.

is the screen really yellow?

is the 3G screen yellower than 2G even with the adjustment of white balance and brightness? is this problem epidemic in U.S ?

thanks!

Well spotted! I thought I was the only one & didn't dare mentioning it for fear of being called a winger! :eek:
