Screen Calibration for Colors

Is it possible to change the screen color calibration other than just changing from Dynamic to movie / professional modes?
The biggest thing that bothers me about the Note 3 is that whites appear a cool blue, and not white especially on web pages and Facebook. Is this something that is possible to fix with a calibration or kernel or something?

There was a kernel for the galaxy s3, note 2 and s4 that had a very deep settings menu for color calibration (perseus kernel), but it only worked on exynos based devices, the dev said it was not possible for him to do the same thing on the ones with snapdragon because of a driver issue.. I will wait sit for this, at least you have a cool screen, mine is green and horrible. Let me suggest "filter my screen" on the play store , its just a filter, and it ruins pure blacks, but with it on the whites are decent now.

Thanks. Does anyone know anything else that may work?

Open the settings menu, tap the device tab and scroll down to accessibility. Turn on "color adjustment". Now you are suppose to tap the color box that closest represents the box shown. You can repeat this process over by pressing menu.

VIEWER DISCRETION ADVISED
Bring the Brightness level down to minimum visible brightness (Preferably when viewing Near Grayscale); even in a well-lit room, or preferably dark setting, you will notice how Samsung managed to hide the Mura Effect on their latest iteration of AMOLED Panels. Some will see notice the predisposing lines, blobs, banding, and two-tone (or even more) gradients, which expresses the true organic nature of AMOLED Panels (Discussed as far back as the original Galaxy S phone).
Now beware, the Mura Effect is normal and does not make your screen or device defective.
Thanks to Samsung's preset for low Brightness levels implemented on the Galaxy S4, S5, Note3, and Note 4, and newer devices (can only be modified via third-party apps), its really hard to make out the Mura Effect on the newer models. Black color is Black, and Samsung's software mod forces no voltage to be fed to the AMOLED Panel when black is displayed, thus the pixels are literally turned off.
I've seen some users post pictures of the smearing (deep purple and pink tint) at "Normal" lower brightness levels (within Samsung's preset levels), which should be taken into account; I suggest them to exchange their devices or replace their displays until they get something better their eyes can be content with.
Every Note 4 and AMOLED device has these anomalies, however, the degree to which the anomalies are visible will vary from device to device. Some will be unable to make out the anomalies thanks to the nature of their displays (Warmer-toned or Cooler toned displays), and should be grateful and move on. If the anomalies are too obvious, I would suggest replace the screen, or live with it and accept AMOLED at its true best.

Downloaded the app and after messing around for a bit I can say that I am unable to make out the anomalies.

The screen quickly turns to black after messing around for a bit. It's good to know that Samsung has made "some" progress in alleviating some of the concerns most previous Galaxy device owners had particularly pertaining to AMOLED displays. However, we all are still far from seeing all AMOLED displays equal and consistent with one another. Some favor warmer colors whereas others favor cooler colors, and some in-between, thus variances will be prevalent until a final solution comes into play.

What "Screen color" Setting do you use on you V40

I switched from my LG V30 to a V40 about 3 day's ago.
I like the things they improved on the phone like the camera's and the reflectiveness of the screen / min brightness.
The thing that i dont like is the color reproduction i just cant get it right. Web gives the best colors but they are washed out compared to the V30 on Cinema. Moving to Cinema colors are blown out of proportion.
Manual settings have the same issue. Saturation neutral is still to much. One step lower is slightly washed out.
When i think i got red on the right value for pictures compared to the V30 a white screen looks red. If i fix that pictures look to green.
What settings do you guy's use?

Left it on 'Auto'. Never one to over-obsess with minor issues. The display is good enough to do colors on its own.

Tried different ones Auto has been the best. It's a bit oversaturated but white point is good.

I see Auto setting still gives control over color temperature and RGB colors. You left those default? (neurtal and RGB maxed out?)
The cinema setting looks a bit more natural compared to Auto. (less overstaturation) And if i compare my picture to the real thing in real life the Cinema setting comes closer.

I believe I found better setting for myself to fix oversaturated display.
Expert mode, default color temperature, saturation and sharpness all the way down?

Found some extra information:
https://www.xda-developers.com/lg-v40-thinq-display-review/
Seems LG screwed up the Expert mode an almost all other color profiles. Googles does a better job using the same display.
Most accurate is the Web profile. Expert is not usable because color tempertature is above 7100K in all settings.
After web comes the Photo profile and after that Cinema. But that feels to overstaturated to me. While web lacks a bit of punsh. I guess that the UI was not made for the web mode and it looks understaturated because of that when using the web mode.
But for now i guess i will keep using web mode. I want to be able to see if the pictures that i take have the correct white balance and thats not possible in cinema mode. Faces look way to red. Same goes for photo but its less extreme.
Lets hope LG does a better job with the new android version later this year....
Out of the box the LG V40 ThinQ targets a cool and punchy color profile that is about 25% more saturated than our standard RGB color space. In the Auto and Expert profiles, it is possible to modify the display’s overall color temperature (albeit in a flawed manner) and to modify the relative reds, greens, and/or blues. The handset offers 6 other color profiles, and do provide profiles that accommodate the P3, Adobe RGB, and the sRGB color spaces. However, all three of the reference color profiles have a greenish-white point, and only the Web profile (which targets the sRGB color space) competently matches its target (though as seen in our Pixel 3 display analysis, LGD’s panels are completely capable of having near-perfect color accuracy with more adept calibration). Furthermore, none of the color profiles support Android’s color management, introduced in Android 8.0 Oreo, and even if it did, it wouldn’t mean much since almost no Android apps support it.
-------------------------------------------------------------------------------------------------------------
Starting at the profile with the most important color space to target, the Web profile does an alright job at reproducing the sRGB color space. However, as shown on the color accuracy plots above, the white point has a noticeable color error shifting towards green, which is also observable on the plot chart in the yellow, cyan, and cyan-blue color mixtures. Pure reds are also slightly oversaturated, but not too-noticeably so. Overall, the profile has an average color error ΔE of 1.7 and a maximum color error ΔE of 3.1 at 100% cyan-blue and 25% yellow, which is mostly accurate and acceptable for hobbyist-level sRGB color work in photos and video.
The Cinema profile, however, is not as accurate and contains a lot more colors with higher color differences. Almost all colors, besides the gamut primaries (100% red/blue/green), are oversaturated, and there’s noticeable error all throughout the reds, red-yellows, yellows, and greens. The white point shared with the Web profile is also too green. The profile has an average color difference that is considered just-noticeable (ΔE = 2.3), with a maximum error ΔE of 4.2 all around the red-yellow-green region. I would like to reiterate that this profile is meant for content that targets the P3 color space, and everyday use of it will result in content colors that will appear oversaturated.
The Photo profile is also not too good, beginning with the display’s green emitter not capable of reaching the full chromaticity of the Adobe RGB green primary; however, the 100% green color difference is not noticeable. Below 100% green saturation, however, there is noticeable color error with a high color error ΔE of 5.0 at 25% green. Yellows also show a lot of noticeable errors, a few other just-noticeable color differences are scattered throughout the gamut. The profile has an overall average color error ΔE of 2.1 (which is technically mostly accurate), but the high color errors the profile contains makes it unsuitable for color-critical work in the Adobe RGB color space.

Odd look and lack of brightness -- Vivid vs Natural display

My 10+ arrived yesterday and so far I've been impressed with two exceptions. As mentioned in other threads my finger sensor leaves a lot to be desired but my point of this thread was about an odd look my screen had. It was not bright and sharp like my 8+. There was a yellowish tint. I went into the 8+ to see if there were any differences in my display settings and I fixed the problem my by changing the screen mode on the 10+ from natural to vivid (Settings > Display > Screen Mode). The options were different on the 8+ but on the newer version it's one of the two, vivid or natural.
Just wanted to share that in case anyone else is having the same issue.
One question. My 10+ came with the screen protector and I've never had one. I assume they take away at least a small percentage of your brightness and clarity? I'm tempted to remove mine to see.

Keep in mind that Natural should follow the sRGB color space. Most displays have default colors that are too cold/blue (high color temperature, and I know, it's counter intuitive but that's what they call it ). Relative to "colder screens", sRGB will seem warmer / more yellow. But it's also much more accurate as far as color representation goes, and should be closer to what you see with your eyes unfiltered by sunglasses. This assumes whatever image you're looking at is also taken with neutral colors and not over saturated.
I usually calibrate all my screens to have more accurate colors, at the expense of that "pop" you can get with AMOLED screens.

That "pop" is exactly what I'm looking for so would you suggest I stick with vivid? I understand what you're saying about the colors but it's not an area I'm real familiar with. I'm just not seeing a brightness on the level I prefer and yes I have it set as high as possible.

Yeah, you'll want to leave it on vivid if you want that "pop". I also know that when my current Google Pixel got the Pie update, the auto-brightness was a bit finicky at first, as it's an "intelligent" brightness and it takes a few days to learn your preferences for the right brightness based on the lighting conditions. So that might be the case with the S10 as well, and I should be picking up mine tomorrow so then I'll know more about how it works exactly.
Also I think I read somewhere that the S10 will only get very bright in direct sunlight if it's set to auto-brightness. You apparently can't set it to that level manually. So perhaps play around with that a bit.

Any news on this? I just picked up my s10 plus and the screen has a yellow tint and seems less bright compared to my note 8...not sure if I just ask for a replacement. Thanks!

I always run mine on Vivid and WQHD and as expected the S10 is spectacular

im surprised there isnt adaptive display mode like on the previous models this really made different colours pop. mine seems to have a bit of an orange tint

I also found it too yellow.. Go at the advanced settings and reduce the green close to the minimum and the red just a little bit. It will look white again..
Because of the sun light some people find yellowish colours more natural..

Yeah the whites don't look good on the s10 compared to my note 8

Just compared mine with different demo models and they all seem a bit more 'natural'. No need to swap it for a different one, allthough they all are a bit different...one more leaning towards blue white and the other to yellowish white.

Well coming from pixel 3, to me, Colors looks natural. S10 screen is crisp and clear. Nobody can best sammy when it comes to screens. I am using natural mode. Vivid mode is having too much pop.

So even I had the same thoughts when I got hands on my S10+. Was worried the screen had some issues and hence went to the Samsung store and compared with the display phones - there was no difference between what I had and the display ones. However, when I compared with my S8+ I found that S8+ display was more blue-ish than S10+. The response from Samsung was that by default Samsung had toned down the blue light in the S10 screens for improved readability.
However, I feel the colors had lesser contrast in my S10+ screen compared to my S8+ and that is a bummer - at least for me!

I have found that applying "blue light filter" and setting it's effect to minimum fixes the color saturation and reverses the washed out look on images. Another way is to go into visibility enhancements -> color adjustment -> then either apply a filter there like "Tritan" or "personalize color" and follow the steps. To me I cannot see any difference between the above steps or just simply applying "blue light filter" set to minimum. To me both look to correct the color saturation about the same.
I hope this helps you!
Hopefully they fix this soon!
Cheers ?

Hi guys. I think you might be encountering the display saturation bug.
The Galaxy S10 (USA Unlocked version in my case) has a peculiar bug in the display. When a photo is fully opened in an app such as Gallery, the photo's saturation becomes muted and cold (even with the display set to vivid and warm). It's very apparent with skin tones. I first noticed this when comparing identical photos between my S10 and S9.
If you hit the app switcher, the minimized card displays the photo with the correct saturation. Maximizing the app, causes the image to immediately turn washed out and Muted. This is appears to be a system wide bug, as it shows up in Gallery, Instagram and other places. I could not get this to show up with a screen recorder, since it's the display changing the image. I recorded it with my camera, but it appears very subtle. In person it is very obvious. I don't know how many are affected by this bug, but I'm seeing others talk about it on forums. Appears to affect all galaxy S10 models.
For a temporary fix, you can enable the blue light filter and set it to the MINIMUM setting. This will display photos in the Gallery and other apps with the correct color saturation. Hopefully Samsung will address this with a software update!

White balance settings S20 FE Exynos

Hello everyone,so yesterday i recieved my new S20FE from my service provider. At first glance it seems to be a decent device. Anyway,while setting up the phone,i found that the "white balance" controls under the display settings,dont appear to be changing any colour aspects of my screen at all. No matter how i adjust the Red,Green and Blue control sliders,the the screen remains exactly the same.
Am i doing something wrong,or have i missed something? When compared to my Sony Xperia XZ2 which also has white balance controls that actually work,i may add. The Samsungs screen appears very dull and the whites are more of a cream tone than actual white,which frustrates me. Has anyone else had issues with the colour adjustment on their S20FE and is there a way to get my whites from cream to actual white?
Any help or advice would be greatly appreciated.

@Trace.Oneil I have the 5G snapdragon version and tested Vivid screen mode today. it was so garish that had to try adjusting the RGB values underneath. that too made ZERO DIFFERENCE on my phone.
I quickly went back to natural.
PS, I can't remember much about it but I've heard there's a 3rd screen mode that's hidden and can be activated with ADB. maybe look that up.

How to Enable Hidden Screen Modes in Samsung Galaxy S20 (Natural, Vivid, Cinema, Photo and Basic) - Techtrickz
The Dynamic AMOLED display on Samsung Galaxy smartphones provides the best visual experience in any lighting condition. And on the latest Galaxy phones, there are two screen modes – Vivid and Natural – under the display settings menu to choose for the best visual experience. But, did you know...

Thanks,i actually found that online and gave it a try. Although there are some differences between the modes,the RGB sliders still dont work with any of them so you cant fine-tune your screen to your preferred colour settings which is a total waste. Why even include it in the software build if it does'nt work.

I was wondering if the other modes take too much power and that's why they were hidden.
maybe that could apply to the slider ?

I doubt it would be a power issue. The mode to me that is the most intense with colour,is Vivid and that is not hidden. I think Samsung forgot about the RGB settings to be honest,and that is probably why they dont work.
