AMOLED Screens tend to differ from display to display, some users get displays presenting a warmer yellow color in presence of white while others get displays presenting a cooler bluish tint in presence of white.
Which presentation would you prefer in terms color appearances on AMOLED Displays (when using the Default Mode: Adaptive Display)? Warmer Displays or Cooler Displays?
I'll be honest when I say that 9300K "blue/cool" whites look more like true white to me, but the industry standards like sRGB, Rec. 709, etc. call for a 6500K "yellow/warm" white point and that leaves my hands tied when calibrating my displays for accuracy.
On that note, Android could use something like system-wide ICC profiles...
In Basic Mode, the display appears more yellow. However, in Adaptive Display, the display look "more cool."
Apart from these Modes, the displays are predisposed to a cool or warm tint, that makes the display appear either cool or warm (sometimes attributes to the pink or yellow tint in presence of whites).

I'll be honest. I've never taken the time to understand AMOLED Technology. It was more the active matrix part but I'll be the first to vote that I didn't.

I'm quite aware of the screen modes, but the white point color temperature and overall gamut (wider gamuts -> more saturation, deeper primaries) are only part of the whole color accuracy equation. The gamma is still far, far off from the 2.2 reference no matter what mode is used. Just open this up in your browser, then you'll wish you had some gamma adjustments somewhere on the Note 4. Maybe Lollipop will save us?

Overall, though, I'd say the most important thing is consistency, which is why standards exist. However, a lot of white LED-lit LCDs and such are much closer to those 9300K blue-ish whites. Mixing those up with some warmer 6500K yellow-ish whites is really jarring, and I can speak from experience there. I'd say for personal use, it doesn't really matter which you use so long as all your displays look consistent next to each other.
I prefer a bluer tint, but only slightly. None of this Xperia Z3 blow your face off blue.
I haven't seen a yellowish screen for a while though. The Note 4 I have leans towards Red or Blue and most other phones i've used lean from red to blue. Mainly red though.
I dislike 6500K, I always have.. For me 6500k white isn't white, it's yellow.

been follwing this for quite time and yes I agree with your post. Being on the note 3 camp , it's the same **** on our end. Recently encho
has been implementing KCAL to aid with changing our color temperatures. More developers should make it a standard to include KCAL in snapdragons.
Dear members,
I own a SM-N950F for a little over a month now.
Since the weather is mostly grey nowadays, I just recognized something strange.
My phones brightness is set to automatic
If I use it in broad daylight and it sets itself to max brightness the colours turn pale and fonts get blurry
Is this intended to be?
Is this to increase readibility?
Are you guys able to recreate this behaviour?
Kind regards
I think its outdoor mode, if you dont want it, dont choose adaptive display on color.
It has been reported - XDA, ZenTalk - by multiple Rog2 owners, that their displays show red discoloration under certain circumstances.
The two contributing factors seem to be screen refresh rate (higher freq -> more red tint) and brightness (lower brightness -> more red tint).
Steps to reproduce the issue:
1) Go to a dark room.
2) Add "Screen Frequency" toggle in the status bar, and lower the status bar to show the toggles;
3) Lower the brightness to 40%;
4) use the toggle to swap frequency from 60Hz, 90Hz and 120Hz.
If your unit is affected, the color of the dark grey areas on screen will increasingly shift toward red as you increase the refresh rate.
Is your phone showing these symptoms? Please share your experience by participating in the poll above.
Same here, hope its just SW issue and will be fix on future updates ?
Yep, I find it most annoying when i'm in a dark room and viewing images or talking over video whatsapp, the pics/vid colours are really dark and reddened, especially skin tones...
to all who answer the poll, pls take photos from the display with another phone and tell us their varriant
specially those who said no!
it seems like my phone doesnt have 40% brightness rofl.
it goes from 39 to 41.
but i dont have that issue with under 40% anyway..
Just a quick question, has anyone tried with an actual grey background? I get the same effect on the screen when the top bar is pulled down but if i look at a grey color palette i do not have this issue. I think its just a issue with the color overlay that asus has set on the top and bottom bar.
Yeah, the red tint is there under 30% brightness at 90 and 120hz, but not as intense as in the picture ?
Only noticeable with nightlight on for me. At lower than lowest brightness controlled by app.
I've only noticed it with the pull down quick menu. but TBH im 50% or above brightness anyways. You can tell the oled panel is red biased - something thats common in industry with oled manufacturers. Samsung went through a yellow and blue bias, Sony had a red tint issue.. Doesnt really phase me as the phone is otherwise sublime
Look, I am telling you, all the units have the same effect.
Those who voted no they are liers that are practising fanboyism or they don't have the phone at first place.
Anyway, if you cannot get along with that then I advise you to return it/sell it and get a device from another brand.
change Theme will help maybe other dark theme.
because white theme not that effect
if anybody vote No, I think they don't use dark theme with orange color.
Yeah there is no lottery here as all displays are affected. Just people in denial or people with the wrong settings who say they have no red tint
not sure if it's just me, but mine seems to have more red tint when the refresh rate is set to 90hz compared to 120, and no red tint at all in 60hz

Would you mind if you can take a screenshot with low and high brithness just to show how it looks as you saying you are not affected by the red tint would be greatly appreciated

You have to take photos of your screen with another phone or camera.
Screenshots are grabbed directly from the frame buffer of the phone, i.e. they show what the phone intends to display, not what it actually looks like on screen.
So in my device its like this,
at 0-30% brightness with dark mode on
60hz - 40% red tint, 90hz - 10% red tint, 120hz - 30% red tint on grey backgrounds .
at 40% brightness and after the red tint goes away.
so weirdly there is less red tint in 90hz mode.
People who have affected devices, can you highlight which variant of ROG2 you have?
For me:
Tint : No
Variant : Tencent
P.s: i believe that the indian variant is mostly being reported to have this issue.

Mine is indian variant and yes its being reported in mostly indian variants.
Hi, I wanted to ask if you guys, have the same effect on your screen. It happens to me only when I'm in low light situations, and it's like, the dark colors, like, mix together with the color that was before in the place that is now the dark color. Only happens when I move any dark/black content on my phone, fast, or not to very fast, but no slow. The best way to see this effect is on dark mode, and on the status bar. Take a reference the white part of your brightness slider. Then, you moove up and down your statusbar, and if you can see it, you'll see like, the dark part of the brightnes slider, shrinks when it's moving (taking as a mark the thickness of the white part of the brightness slider). At first, I thought that this was like a system effect (animation), but then, I saw it on a photo, the same effect, so I think that my screen is defective. I upload a video in slow motion for a better look, and to understand me. Also, I forget to say, but in the video you won't notice it, but, the part that shrinks on the brightness slider, it color, slightly changes to a blueish color.

haven't watched the video, but i think what you're describing is black smearing, it's an amoled thing becuase when black is onscreen pixels turn off

I don't quite understand what do you mean. But for my mi 9 lite, when the screen is all black and only has a few places of lighted up areas, those pixels seems to last a bit longer after it had brightened up.
Idk if that's just what AMOLED does.
This is normal for OLED screens, i have seen same effect on Samsung Galaxy S3 - S9, Nexus and OnePlus phones. Black = off pixels. When they turn from black to something else, they need to turn on. This causes a delay, which leads to the blurry purple affect. It can be slightly annoying but the colors, saturation and contrast outweight the con's IMO, i dont see myself coming back to IPS.
It also happens to me in the Mi 9 Lite. It seems to be some technology used on the screen.
There are a lot of posts and review mentioning this problem about the camera, photos, and videos, but it's not just the output coming from the lens: it's the entire display.
It's not just that it's pinker than other devices: when you look at photos of humans or things you know were supposed to be yellower, it's noticeable and looks wrong, even without another screen to reference. Humans look especially piggy-pink. Sand looks pink. Wood looks pink.
Yes, it's possible to adjust color balance from the Settings menu, but if I adjust for reds, the whites become off-balanced: too yellow-green.
The color temperature wheel also does nothing for a separate issue: contrast and saturation. In Normal mode, it's too muted. Meanwhile, "Vivid" mode comically oversaturates. Compared to a Pixel 2 XL and Pixel 4 XL (and other screens, mobile and desktop), colors (in Normal) are more muted than expected. Parts of images that should be charteuse or neon are instead just nearly-pastel yellow-green. Darks and blacks are nearly greyish.
Can anything be done to calibrate the screen, via root, apps, or otherwise?
