When increasing brightness from 30 to roughly 50% (the control does not show percentage #s), the issue on mine pretty much disappeared. Will try 40% and others to see where it's minimal but, at least for my needs, I don't think it's going to be an issue as it's only visible at a certain angle and at certain brightness, though in a venue where one needs only 20% brightness it could easily be bothersome. But it seems like this might just be an OLED thing, like how old TN panels had massive hue shift problems from angles and I'll take OLED's nitpicks over TN's any day.

From a manual search, it looks like OLED technology can emit this as a normal artifact and may not be of concern, quality control notwithstanding. And yet, if the same model screen can be more pronounced at the same brightness settings for some more than others...

Another possible cause might be the anti-reflective coating on the screen OOTB being the culprit, and adding a privacy or clear screen protector with its own antireflective properties likely won't counter that either. (Side note, apparently, LG has better control over PWM, which might mean that more LGs will be in the new phones.)



I then asked an AI engine about this, so here's what it told me and I'm not making this up:

A pink or green tint on an OLED screen is often a normal characteristic of the panel, especially at low brightness, or it can be a sign of a bad panel. Solutions range from adjusting software settings like color modes and brightness to exchanging the device if it's a severe panel defect.

For a mild tint that you want to minimize:
  • Adjust screen settings:
    • Brightness: Lowering the brightness can make the tint less noticeable, as it's often more apparent at low levels.
    • Color Mode: Change the screen color mode in settings to "Vivid" or "Natural" to balance the colors.
    • Night Light/Warmth: Turning on a night mode or increasing the warmth setting can counteract the green or pink tint.
  • Update software:
    Ensure your device's operating system is up to date, as manufacturers often release software updates to address these issues.
For a significant tint that bothers you:
  • Exchange the device:
    If the tint is severe or appears on a new device, it could be a panel defect. Contact the manufacturer or seller to see if you can exchange it for a new one.
  • Contact support:
    If you are unable to exchange the device, reach out to customer support for assistance.
  • Watch from a different angle:
    If the tint appears to shift with your viewing angle, it's likely a characteristic of the panel. Try adjusting your viewing position to find an angle where the tint is less noticeable.
 
What do you mean by “grain”?
It's hard to describe but I guess I'd say it has a sort of paper like texture when viewed on a white image. On My previous air I could notice it in low light just watching videos. I have no idea the cause behind it and I assume the effect is present on all the display models to some extent.
 
My 16PM had a GH3 panel, and it was great. All panels vary to some degree. I was at best buy the other day looking at the Fold 7. It shifted green but at a much greater angle than my GH3 17PM that I returned. If my 17PM GH3 was like that I would have kept it.

So almost like when you see the effects of a Paperlike screen protector?

I don’t have any of that on my GVC. What brightness and room lighting?

I created 3 shortcuts that set my brightness to 40% 50% and 55%. I use these as the day moves on to change brightness. I don’t use auto brightness.

You could use the same for testing with specific accurate brightness percentages as the parameter you provide is a percentage.

So we have some data about models and panels brands , and we know that the 17 pros are Samsung for 85% of the cases

But what about specific serials ? Do we know how many G9N there are , compared to G9Q?

My first 17 pro was g9n and it was perfect as far as screen goes

My second unit is g9q and it's actually pretty bad

Idk if I should shoot for a g9n of its it's hopeless

Why did you return the “perfect” first G9N?

So here’s my most recent Air, GVC panel according to sysdiagnose, not that I care what it’s called – I just don’t want this green shift.

hWSAa3.jpg


Uncropped and unprocessed photo taken with my 13 mini main camera (26 mm-equivalent), obviously from fairly close (about 8 inches).

The camera’s auto white balance made the top look magenta as it tried to compensate for the green bottom, but in reality the top was still pretty neutral at this angle and the bottom was even greener.

Ignore the PWM banding from the 1/266 s shutter speed.

This really doesn’t work for me, for the way I use my phone.

I don’t care about absolute neutrality or perfect evenness at a perpendicular viewing angle.

But I can’t stand this strong green shift that comes on so abruptly at a specific viewing angle – the exact angle at which the words “Night Shift” are being viewed in this photo.
Looks like a brindle, like a greyhound.

I took a few pictures of mine, and it’s funny how they don’t really capture the slight pink tint at the top of the screen. This is already my second replacement, so I’m not sure if I should go for a third one or just live with it and stick to dark mode, haha.

From the research I did, those serialized prefixes that identify panel type are actually the manufacturing facility location and production line. They may match to the supplier, but I found no evidence indicating quality or preference rating, aside from some random repair shop’s website that wanted people to overpay for Samsung replacement screens.

Thanks.

That’s a few confirmations now that some regular 17s with 256 GB do have a Samsung panel.

I’d love to see at least a couple of confirmations for the 256 GB Air. Every Samsung-panel Air reported in this thread where the storage capacity was also stated (which is only a few) had more storage than base. Which intrigues me but might just be a coincidence.
I have a Space Black 256GB Air with a G9Q display, from the US.

would it be far fetched to believe that certain facility locations are more strict in regards to QC ?
 
I’ve got a 17 pro 256 silver with a G9Q panel. Seems like a pretty rare combo? As all the G9Q seems destined for the Airs.

Comparing to my 15 pro LG GVC which had a noticeable but not entirely unpleasant magenta hue: both are very uniform with acceptable shift off axis. I went through maybe five 15 pros so I definitely saw some bad ones. The G9Q might be the best panel I’ve had in some time. The white balance tends green but that might only be because I’m comparing it to the magenta 15 pro.

The 15 pro was maybe slightly more pleasing at low light in dark mode, as the magenta made text pop on black.

The 17 pro G9Q has what I can only call the “lushness” of high quality Samsung panels, rich whites and good light evenness at off angle. Happy with mine.

Had three airs. (all 256gb)

The first one with the G9Q is by far the best of the three. No unifomity issues at all. Perfect white balance an no colour shift.

My wife has a white air with a G9P. Its also okay but a little bit worse than the G9Q.

The last one was a GH3. Very poor uniformity and a lot of green colour shift when tilted.
