iPhone 12 Pro Yellow Screen/Tint? Display seem "Warm"? Check here first!

The problem I personally have is that I’d like to check the possible bias of my subjective impression by using objective measurements, and I’m limited in that by the possible inaccuracy of my i1 Display Pro. Actually I have two units, an older one and a new one, which give somewhat different results. I suspect the new one is more accurate, but that is mere speculation. I have no way of knowing if the colorimeter just happens to have a bias in the same direction as my own color perception. Simply assuming that it doesn’t might just be confirmation bias and wishful thinking. If I simply assume that my perception is right, I wouldn’t need to measure in the first place, except maybe to convince others that I’m right — and that in turn would be questionable if I don’t know whether my measurements are actually accurate. So, it remains a bit unsatisfactory.

I definitely agree with that, but in my case I compared my 12 mini to a large variety of other displays (both OLED and LCD). All of them are very similar to each other, except the mini. It has a very visible green tint to it.

So either the mini is correct and every single other display I own is wrong (one of which was factory callibrated and came with a callibration report). Or it’s the mini that’s wrong. Which would seem more likely.

I mentioned metameric failure before, which is a real thing with RGB OLEDS (and I assume by extension Pentile). Even if they measure to be correct, they’ll still be perceived as slightly green tinted compared to an identically callibrated and measured LCD. Their whitepoint needs to be slightly offset towards magenta to get them to visually match with an LCD.

From what I’ve seen only the iPhone X was callibrated to account for this and every iPhone since has had the green tint.

Yes, few people commented that their latest production week(51 and 52) has this issue.
you can read about it here https://discussions.apple.com/thread/251997533?r_s_legacy=true&page=71

Issue I am talking about is:-Raised blacks, flickering and green tint.

Mine is week 51 (12PM received yesterday) and has constant raised blacks up to 25% and flickering between 25 and 50%. It is hardly noticeable, but annoying considering the price of the phone. I have a service appointment in 1 1/2 hours. I’d also guess the flickering could affect the battery to some degree?

what do you think apple will do about it? Will there be a big recall and will it replace all iPhones? I dont think they can be fixed via software

I have been following this YouTube "Zollotech" and even he has noticed this issue on his iPhone 12 pro, and he's optimistic that it will be fixed via software update.
"at 4:49" he mentioned about this issue.

And, what I believe is that company like Apple cannot get it wrong, given the fact they have been in Oled phones since 2017.
Also, had it been hardware or batch related or anything with supply chain, it would have been sorted out in the new batches, and looking at the comments on various forums that is not the case.

I guess the problem is somewhat widespread, and since it can be replicated only in certain circumstances, lots of people ain't aware of it. The best example I can give you is, this YouTuber "zollotech" he posted a video about a month ago about green tint and raised blacks, he didn't notice this issue on any of his phones. And as per his latest video, which I have linked above, he did able to see it on his 12 pro.

I am not sure about the battery maybe or maybe not, depending upon the dark background you have been using.
Do share your experience with the service executive and what they know about this issue.

Spent sometime and here are the links about the green tint display on iPhone 12 mini.
Apple Support Forum, it might get locked down eventually
Linus Tech Tips Forum, we might get a big help if Linus decides to do a video on it
Below are reddit cross posts just refer to the LTT forum post I made
r/apple; r/iPhone; r/hardware
negative points at r/iPhone 3am at night already, whatever

Here's the IMGUR post I intended to use for reddit, but failed so..

The technician didn’t know about this issue at all, but he told me I should just get it replaced. Apparently I can demand a new one if it’s within 14 days of ordering, and it’s been 4 days. The people I talked with on the phone didn’t know anything either. Anyways, I’m sending in my phone and will receive a new one early next week.

Welcome to the screen lottery :)

I am totally confused from this thread about what appears to the problem with the display. Is it yellow, is it green, is it not black, or what...?
 
I have managed to capture on video how the screen becomes yellow with TT on in a dark room. however, as I move close to a window, you can spot how it changes back to very white!

problem is - not captured - that when close to window/light, with TT off it becomes a bit yellower

to summarise:
With TT off:
- indoors low light: acceptable - don’t mind it ✅
- indoors close to a window / with enough light or outdoors: a bit yellow ⚠️

with TT on:
- indoors low light: unacceptable - proper yellow ‼️
- indoors close to a window / with enough light or outdoors: very white ✅✅

Given the screen is capable of displaying that white colour, it should be something solvable via software update... although the issue remains with cases of screens that are different to begin with - some might be “over adjusted”.

The only thing I have observed with my iPhone 12 mini is that with TT on inside, it is very yellow compared to my iPad Pro. However, with TT off, it is nearly identical to my iPad Pro. That indicates a software issue.

What about outside during the day without TT vs with TT?
In my case the best result is TT off inside and TT on outside

I'd say it would be nearly impossible if all screens aren't already identical but as seen it this thread - they are all a bit different. It would require each display measured and then corrected. Possible but I find it unlikely and cannot be done remotely.
Only thing that could work is that if displays are identical in certain oled batches, to detect which is which and then make individual correction tables for each batch.

Anyway, I don't find my display colors too bad but I hate that upper and lower half of the display are not identical. Bottom is dimmer and a bit greenish while upper part brighter and pinkish. But I guess many peoples are not sensitive to this issue?

This is what happens when I turn on True Tone outside
Note it’s almost dark here in the UK, but still the light is enough for TT “on” to lead to a whiter screen

To most people, nothing. To a vocal few, everything you mentioned.

Most people just don’t care about proper display calibration. That it’s not a problem to the vast majority of people doesn’t mean it doesn’t exist.

If you’re happy with your display then that’s great for you.

Comments anyone? Similar behaviour? Different behaviour on your devices?
 
It's not just the display that's yellow tinted, it seems there's something wrong with the sensor which makes photos and videos also tinted. Here's two photos taken side by side at the same time. Left one on my iPhone X and the right on a brand new iPhone 12 Pro Max I got yesterday.

To be clear, IRL my ceiling and walls are a very slightly off white grey color, and those fan blades are grey. The iPhone X looks true to life. The 12 Pro Max looks murky yellow/green, like I've put some 2011 retro IG filter on it.

At first I thought it was just the display and could compensate for it, but when I sent the 12 Pro Max pic to the Iphone X, it still looked strange. On the 12PM, the yellow/green picture that it took looks even more yellow/green.

My wife got the same phone, same day, almost identical except her's is slightly more green tinted.

I've heard a lot of talk about the display but has anyone else noticed this tinting issue with the camera itself?

FYI. ‘Never heard of that’ is the first thing they are trained to say.
Also, you can do anything within the 14 day return window.

I don’t like how this thread has devolved into a general complain thread about the new phones ... what’s next, battery issues?

Inside TT is too warm, outside in bright light, I don’t see a difference between TT on or off.

Tested that but the picture on my 12 and XR had very similar whites...
 
Hi everyone. I’ve reviewed the previous 10-15 pages of this thread and haven’t been able to find an answer to this. Has anyone reported a 12 Pro Max without the raised black issue?

Asking because I’m due to receive a replacement for my launch day 12PM (raised blacks, green tint, flickering) tomorrow. Hoping the replacement will at the very least minimize the raised black issue, but at this point I’m not terribly optimistic.
