If you're comparing the phone at home and at work, chances are the colour temp at home (probably incandescent light) will make the screen look a lot warmer than at work (probably fluorescent light).

Ambient light temperature does seem to impact the colour temp of the screen in my experience.

I tend to agree on this as well. Most of my house lighting is incandescent (exception of kitchen, which is florescent) and I can clearly tell the difference. To be honest, warmer screen doesn't really bother me at all and I actually prefer a warmer temperature over the cooler temp.

No previous iPhone has exhibited this for me. I've either had a cool screen that becomes more bright/less bright depending on the available light, or a warm screen that becomes more bright/less bright depending on the available light. The 6S+ is the only screen where I've ever experienced a shift in colour temperature. Mine can go from being cool to neutral to warm depending on the lighting levels. They also have a much brighter screen than I've ever experienced and dimming them to the level you'd ideally want causes an unacceptable shift in colour temp, so I have to run mine with a higher brightness than I would previously have done.
 
Apple is shipping millions of phones. I doubt the QC and/or technology production quality could possible make every single phone screen great.

I have a yellow tinged, interlacing 5s that I just got. Maddening... But, everything else seems to work. Damn perfectionist tendencies :mad:

Strange isn't it. Whilst I experienced this myself on my 6 Plus as well as my 6S Plus, I didn't on any iPhone or iPad before this.

Maybe Apple is using a new backlight defuser that reflects some ambient light back. Who knows.

My 6+ never did this, it was the best screen I've ever had. Crisp, colourful and totally non-fatiguing. The 6S+ are bright, fatiguing screens in my opinion and I expect a lot of the fatigue is due to this colour temperature shifting.
 
Does your current one still do it sunking?
It didn't for a day or two but it's doing it now! It doesn't go into the horrid smokey washed out 'mode' in dim lighting that my previous one did but I have the weird shifts between cool/neutral/warm. Most annoying.

Yikes ! How's your Samsung chip holding up?
 
Anyone know if turning off auto-brightness may help? I am trying that now.

I am fine with the slightly warmer tone normally, but when it shifts to an obvious yellow - I've had many iPhones and this is the first one that's doing it.

Switching off auto-brightness does nothing when the colour temp is 'having a turn', and nor does it prevent the issue.

Hmm. So many variables at play here, not just the chip. My old phones were on 9.0.1 and ran great. This new one came with 9.0.2 preinstalled and battery life has been rubbish out of the box. I did a clean install of 9.1 and it is definitely better but still not a patch on my previous two 6S+ phones, nor my old 6+.
I'm getting 8-9 hours of usage time when my two previous phones returned 10-12.5. My old 6+ gave me 9-10 hours so I'm not happy at all. I'm not sure how much of this is to do with 9.0.2 and 9.1 though. If only I could try 9.1 on the two phones I returned...:rolleyes:

I went to my local Apple store yesterday to purchase a 6s. While waiting, I decided to check out the display 6s's and they all had uneven tinted displays. You can't avoid them, it seems.

The way I test for display uniformity is to take a screenshot of white-heavy page (like Settings). I then take a screenshot of that screenshot, rotate it upside down, and compare how the two images look when holding the phone such that the image isn't upside down (so basically, flipping only the phone).

If the images look different at all, then there is a uniformity issue. Usually, it seems to be with the top and bottom of the displays. On my 6s, for example, the top is dimmer than the bottom.

I already returned my 6s+ a while ago because of something similar to this, but I don't want to have to go through the whole return process and wait for Apple to get their QC together because they probably never will. My 6s is flawless otherwise (unless the Samsung chip is actually worse than the TSMC), so I probably won't bother.

For an ~$800 phone (6s SIM free 64GB), I expected better, especially from Apple. But, it seems they don't care to give the best quality displays to their phones.

I'm on my third phone now but none of them have been right. I haven't swapped for 'perfectionist' reasons either! The first had a very dodgy home button that failed to register the majority of presses. The second had a strange screen issue where it became dim & washed out at random times, and this one has appalling battery life. I haven't swapped for screen pressure blotches, uneven backlighting or because I have a Samsung chip. I firmly believe that a working home button, decent screen and battery life comparable to the two previous phones I exchanged are perfectly valid reasons to exchange.

This thing cost me £699 and I'm not going to settle for any glaring faults. Trouble is, they're out of stock again so I'm having to go through the terminally tedious rigmarole of checking the Apple website twice a day. Oh and at this point I'm fairly pessimistic about receiving a fault-free phone. What will I receive next time and at what point do I give up and get a refund? I've sold my old 6+ so can't return to that, not that I'd want to, so where do I go from here? The QC is disastrous for such an expensive product. I think the problem is that iPhones are just too damned popular and Apple can't keep up with demand, let alone check for faults before they're boxed up. I sooo don't want to be forced down the Android route but I'm getting pretty sick of this exchange business.:(

I will hasten to add that if you manage to stumble upon a fault-free 6S+ it's a cracking phone. That's what annoys me, I want one!

I suggest going through with express replacement. Apple will overnight you phones over and over until you find one you like. At this point they are all brand new too.
 
My 6 compared to my 6S replacement (exchanged due to fingerprint below glass!)

My original 6S had a perfect white screen :(

Should I keep exchanging?

Both are at the exact same brightness level.

Yes. Keep exchanging until you get a screen that isn't yellow. White is supposed to be white..
 
Got mine exchanged today again. Not for the yellow tint issue but for the dead pixel issue. So far no yellow tint issue on my new 6S Plus.
