A Plot Twist on the S24 Display Saga

I have this problem too

UPDATE 1: Also read the post I marked as solution, it contains additional information based on some tests.

TLDR Version: I think it is a driver issue causing incorrect color reproduction and not a question of vibrancy or saturation, for details read below (reading time ~6 minutes...)

So I am an IT professional, AI expert, and tech enthusiast, I had the S23 Ultra since its release at the beginning of last year, it is a perfect and flawless device, everything just works, very polished, no-compromise experience.

When the S24 Ultra was announced, I saw it as a sidegrade, not much to be excited about if you already have the almighty S23 Ultra, and work daily with professional AI tools, but with the attractive pre-order promos I thought why not, a new toy for the new year, and you know life is short so enjoy, I even doubled-down and ordered TWO, one for me and one for the wife!

Because with Samsung something must always go wrong (in my experience at least), one of them got lost in the mail and went to another country, but thanks to probability theory, one of them arrived the next day and I have been playing with it for a few days now.

Of course out the box, the cold frosted grey titanium looked and felt super premium, and high quality, it was love at first sight until (as you might expect) I turned it on and a picture displayed on the screen, I was like huh... Why does this screen look so bad?? That is not the typical experience with a new Samsung phone where the screen is usually a WOW factor every year!

Fast forward a few days later, I got to learn about the "dull display" saga, and the polarized opinions between the group that thinks it is the best display ever, to the other that thinks it's outright unacceptable, and everything in between.

Below are my reflections:

1) From my experience, what is happening with this display is not a down-tuning of the color profile towards less saturated colors, nor is it a settings bug where switching between vivid and natural doesn't do anything, on the contrary in my observation there is a very noticeable change between vivid and natural and even effective temperature tuning settings from cold to hot.

2) The screen looks like a Windows or Linux PC without the correct display driver and/or color profile installed, what I think is happening is the colors reproduction and representation is just wrong, the color space coverage and greyscale gradient are not fully displayed, this results in all sorts of phenomenon described by users, so-called washed out and boring, grainy greys, lines, etc.

3) This is easily detectable in isolation by just using the phone without comparison, but more obviously in comparison not only with other Galaxy phones, but the screen colors look off in comparison to my OLED and QLED TVs from Samsung and other manufacturers, even in comparison to my laptops from DELL & HP, which don't use a "vivid" profile at all, the screen colors on the S24 Ultra are simply just OFF in general.

4) Some users say that this problem is present only in phone menus and icons, but not in media playback, videos and apps, in my experience this issue is present throughout with the exception of HDR10 (DCI-P3 content).

5) Today I played an HD video on both the S23U and S24U side by side, the video shows flowers and landscapes, the difference in picture quality was shockingly significant, the S23 Ultra had that "3D effect" where flowers and trees feel like they are popping out of the display, a similar effect to my Samsung NEO QLED TV, which is an indication of a very high picture quality when everything is just right, however, on the S24 Ultra the colors were muted and the display looked darker despite being technically brighter, and of course no 3D effect.

Under these findings I contacted Samsung's technical support, and the person I talked to was wise enough to escalate the case to specialists in the product team, and not try to give his random opinion like all the other cases we have seen in the news and other posts, so I am hoping for a responsible and conclusive response from the product specialists.

Under these circumstances, I personally have no option but to unfortunately return my S24 Ultras, if I don't get a conclusive answer that the display drivers will be updated, I don't mind natural colors, but they need to be correct colors covering the wide spectrum the display specifications support, until then, I will be rocking my trusty S23 Ultra until we see what the S25 series brings to the table next year, at the risk that life is too short and I might not be around next year!

Thank you for reading and apologies for the long post...

I've just spoken to samsung technician on the phone re another issue but also mentioned this, and got the same response as everyone else has got, that it's intentional by Samsung. What's the point in having the two different modes 🤔. Doesn't sound like they will fix it if they are giving the same script to the technicians 🤷🏼

@Bt32 Thank you for adding this excellent piece of information, exactly the kind of comments I was hoping for to move one step further towards demystifying this phenomenon, in light of the complete absence of reliable or official technical explanation from Samsung.

I conducted a small experiment based on your input, I have YouTube premium so can run HDR10 videos in a PIP (floating picture-in-picture) and observe what happens on the home screen and inside apps, in both S24U & S23U side-by-side.

1) It is obvious that both phones switch equally between sRGB and DCI-P3, depending on the content, when the video is not running both are on sRGB, and when HDR video is playing both switch to DCI-P3.

2) The very interesting case is when both are in DCI-P3 mode they are very similar, minus the S24U looks a little darker due to the matt antireflective tint, in this mode both show washed out icons on home screen and even more washed out when eye comfort is enabled, this makes sense because HDR significantly brightens the display via elevated Gamma levels so the SDR icons become washed out, I also ran the Display Tester App in this mode and the solid colors look very similar, just a little darker on the S24U due to the previously mentioned tint. Conclusion of test1: both displays have practically identical DCI-P3 profiles, and perform very similar.

3) When you close the videos and go back to sRGB on both phones, this is where the biggest change happens, both displays become instantly more vivid and Gamma is lowered, the S23U becomes extremely colorful with high saturation, while the S24U becomes also more vivid but with far less color situation. Conclusion of test2: in sRGB profiles the S23 has a significantly higher color saturation, while the profile is dialed down on the S24.

This test leads me to believe that all this fuss is as simple as Samsung changed the sRGB color profile in terms of saturation and possibly gamma levels and forced it on everyone, so many ended up very unhappy, and rightfully so.

The solution seems as simple as was mentioned multiple times, that Samsung must make the right decision by giving people several profile options, like Natural, Vivid, and High Saturation / or Legacy Vivid, or even better, do like Xiaomi and give people more display control over gamma, saturation, contrast, sharpness etc, similar to TVs, so users can dial the settings they prefer.

Now after all is said and done, at the end of the day, due to Samsung's bad UX decision, the S23 and below remain better in sRGB which is 90% of the day-to-day usage of most people, so until Samsung decides to make it right by giving people multiple profile choices, or more control over display settings, the S24 line remains interior from a user experience point of view.

This seems like another problem, I can't reproduce that grainy effect on my S24U, if not a driver bug it could be a hardware issue, did you try a factory reset or not usuing smart switch, look at the picture of my S24U, taken by S23U camera, nothing strange there

No smart switch done but I'll try a factory reset as I'm planning anyway to either send it tomorrow for a replacement, or for a reimbursement.

Thanks for the insight anyways.

Here are two more pictures in a dark room at different brightness levels for reference, it looks a bit grainy in the pictures but in real life it is perfectly uniform, even in comparison to the S23U which has a slight grain visible in the dark.

The Samsung technician I spoke to told me that "Samsung engineers are aware of the problem and working very hard to fix the problem. It should be fixed in the near future with a software update." I called them Friday morning EST.

Are you in USA? Maybe certain regions will receive a fix and others won't. I noticed the hideous display as soon as I got the phone. I have until February 9th to return my S22 Ultra for this S24 Ultra. If they don't fix this issue by then, I'm definitely keeping my S22 Ultra and sending this one back.

No I'm in the UK. I'm in the same boat, I have until 7th Feb to return my iPhone 13 pro and I've been holding off! I'll have to send it tomorrow though in order for them to receive it in time 😭. I've got a camera issue as well 🙄

Well I'll eventually ask to replace it. Maybe just a faulty batch
