Display Yellow Tinting..

I've noticed on my 8.9 Tab as with lots of recent other Samsung Tabs (the 7.7 included even though its an AMOLED) that the display basically has a yellow tinting.. no, actually, its all yellow. there are no whites in this tab, just yellow. Ive seen others on display at stores and to a more or lesser degree they are all like this. You can tweak somehow the display characteristics under the MODE in Display options but that really only makes it worse (choosing the MOVIE mode makes it even worse).
I had THE VERY SAME PROBLEM with my Galaxy Note (along with countless other people) but fortunately there is a app written for it that fully adjusts the RGB values​​, change the sharpness and color temperature for Dynamic, Standard and Movie modes. Its like magic and is not not a service or background process, its written permanently into the system's settings and done!
http://forum.xda-developers.com/showthread.php?t=1366280
Unfortunately this app doesn't not work with any other device Ive tried.
Now, there are a few (lame) apps on Google Play that allow for some degree of color correction but none of the really cut it.. by the time I add more Blue and Red and reduce contrast to tweak the yellow cast, lower gamma tinting appear and the yellow is still present. Is there a proper way to color calibrate the display on the 8.9 via software, editing props or changing code that gives instruction to the display hardware's characteristics?
The people at Samsung MUST be all blind to this on just about all their Tabs. I must say, as much as I detest the iPad, color-wise they are ALL always spot on! I am yet to see one that is yellow..
Thanks for the input!

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.

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!

General Samsung should add more screen modes

As you know, the S21U only have 2 screen modes, Natural and Vivid.
I prefer Vivid but it makes my edited photos too satured, and Natural is at the total other extreme with desaturated colors!
Samsung should give more options for screen modes adding an in between mode or why not letting us set the saturation manually because none of the actual modes is correctly saturated.
Also it would be great to give DCIP3, Adobe RGB and srgb choice

With the advanced settings and white balance offered with Vivid-mode is sufficient for my needs.

That doesn't work on the s21 for me

From what I've heard, "natural" is actually pretty darn accurate now. I don't know what else one could want.

It works on s21 ultra, you just need to put natural, not vivid first, trough phone settings, then do the adb code as shown above.
after setting the mode from adb, go to the display-screen settings, and just exit(without choosing anything)
