Got my iPhone 4S, but...

[Simon]

I'm definitely disappointed with the colour rendering on the 4S.  If it's supposedly down to glue not being set, how long are we expected to wait for it to do so?  I have to say, I'm considering whether this is a returnable fault. 

[Steve]

I think you need to talk to Apple store support Simon.Mine is not yellow and I think I mentioned one of the possible reasons  but that may not be the cause for you. Maybe Gary will have some more information.

I know in the past people have swapped/returned 'yellow' phones.

[pctech]

Yep I'd return it double quick.

[Simon]

I'll give it a day or two to see if it improves, but I may talk to Apple in the meantime. 

[Steve]

If you read the article it implies that yellowing from clue tends not to be uniform across the screen but occurs in blobs

[Simon]

I'll do some reading up this evening.  It's better on full brightness, but of course that will kill the battery.

[Steve]

I've just compared mine with a version 4, we could not detect any colour differences.

[Simon]

I'm comparing mine to my 3GS.  I'll post some screenshots later, but even the forum doesn't look quite right. 

[Steve]

I think my 4S screen is a warmer colour than my 3GS, the blues are not as cold. Strangely the colours now approximate to my MacBook screen. I've had a scan of Apple communities and there may be some inconsistencies in the screen calibration, they do apparently use 3 manufacturers.

[Simon]

I've just discovered something really weird.  I took screenshots of the forum index on the 3GS, and on the 4S.  On the 3GS it looks normal, identical to as it looks on my PC screen, but on the 4S, the blue looks washed out, and slightly 'yellowish' - this includes the OS graphics as well.  However, I emailed both screenshots to myself, from each phone, and in the two separate emails, the pictures look identical, and the colour of the screenshot from the 4S is perfect, and very different to how it actually looks on the phone.  This surely indicates that it's the actual screen itself that is producing the 'warm' effect, doesn't it?

[Simon]

Here's a very poor quality pic of both phones side by side, but it does show the colour difference.

The imessage thing is fun. If you're connected to the net when you receive a message from another user, you can see when they're typing

[Simon]

I've got a male Siri, but I've heard talk of a 'she'.  Can't find an option, though. 

[Steve]

Maybe a country thing

[Simon]

Well, I've booked a call from Apple for Sunday, so I'll see if the screen has improved by then, and if not, what they have to say.  I don't think I can just live with this, knowing that other people's seem OK.  You'd think there would be better quality control with what is supposed to be a high end product.

I was going to post this earlier on but I thought I'd misread or misunderstood your post. Comparing screenshots won't tell you anything because they will always be identical when viewed on the same device.

In the past Apple has allegedly used colour profiles contained within the iOS to make the displayed output look warmer (yellow). As far as I'm aware this is not the case with iPhone 4S so I suspect it is the display screen that's giving the yellow hue. It appears there have been a lot of complaints about it but as yet, no response from Apple.

The screenshots were taken on two different devices, the 3GS and the 4S, then mailed from each device to my main PC, as that was the only way I could see to do it.  Therefore, surely, each picture should have been representative of what was taken by each device?  Doesn't the fact that the picture produced by the 4S looks totally different when viewed on the device, to when it's viewed on the PC, and the picture from the 3GS looks identical on the screen of the 3GS, point to an issue with the display on the 4S?  If you follow...  Also, I know how the forum should look, and it doesn't look right on the 4S.

[Simon]

Thanks for the link, Zap.  It's not so much the whites that are a problem, it's the blues that don't look right.

It does point to an issue with one of the device displays and most likely the 4S but the screen shots are not representative of that.

Imagine you had an image that was pure red. The file that makes up that image would only contain hexadecimal values of #FF0000. If you display that image on a device with a defective screen it might look orange for example but if you took a screen shot it would capture red or #FF0000 even though it appears to be orange. Or to put it another way, a screen shot takes the data from the device memory, not the component that makes up the display.

[Steve]

It's not easy but if I compare your 4S and 3GS images with how I have the calibration set on my Laptop, I'm much nearer the temperature of the 4S than the 3GS, I have to change the screen calibration from a neutral white to a coolish blueish white to approach the blue of the 3GS

Your mobile phone number becomes associated with your Apple ID email address so if Simon now tries to send me a text he should see a grey iMessage in the input box(BTW Simon seems to have iMessage enabled) if iMessge is not available normal carrier rates and routes apply.

Thanks, Steve.

[Steve]

The message program gives a different background to iMessages i.e. blue ,carrier SMS is green.

Morse code is...? 

[Steve]

Black and white.
