In some ways, the Galaxy S24 Ultra’s display is Samsung’s best ever. It finally upgraded the PWM dimming rate to match the iPhone, and Samsung’s new anti-glare filter made it easier to see in sunlight.
But the issues have been brewing under the surface and have slowly developed over the past year, which makes us wonder if Samsung will fix them in the upcoming Galaxy S25 series.
From the grainy display to dull colors, Samsung has some work to do on the display quality and configuration. We’ve also seen Galaxy S24 Ultra models with permanent smudges on the screen, a sign that the oil-resistant layer is wearing off prematurely.
Finally, Samsung is one of the only companies left that doesn’t offer PWM dimming and eye-friendly dimming options for those sensitive to flickering LEDs. Samsung needs to improve the Galaxy S25 Ultra’s display to regain the crown of the phone with the best display.
Granular display
Initially, users complained of a grainy display. While this is mostly noticeable at low brightness levels, some users have noted that they can see grain even at regular or high brightness. This problem, technically known as “Mora,” is something we haven’t seen as widespread since the days of the Google Pixel 2 XL, and it persists even today on the Galaxy S24 Ultra display. You can see the uneven pattern in the image above that I captured using a microscope on my Galaxy S24 Ultra.
The grainy problem is caused by manufacturing defects where adjacent pixels are not as bright as each other, causing them to appear mottled or grainy. All pixels on an OLED are individually lit and part of the manufacturing and calibration process ensures that each pixel meets a certain uniformity level.
It is unclear whether Samsung is skipping this step or if the M13 generation is specifically prone to this granular issue. What is clear, however, is that no other phone with an OLED screen suffers from this problem in such a big way. one Rumor of November Samsung is said to have fixed the issue by using M13+ panels in the Galaxy S25 Ultra, but we’ll have to wait and see if that’s the case.
Permanent jobs.
Everyone has to clean their smartphone display of smudges and grime from time to time, but some unlucky Galaxy S24 Ultra users have noticed that their screens are smudged. Never go away.
This is believed to be caused by premature degradation of the oleophobic coating on the outside of the display. This coating is applied to the glass to minimize fingerprints and smudges, as it is naturally resistant to water, oil and other liquids.
The result is a display that looks permanently dirty, and only a glass replacement will fix the problem. Even worse, one Android Authority Pool Shows that probably 50% or more of Galaxy S24 Ultra users are experiencing this issue. Our advice to Galaxy S24 Ultra owners without this issue is to get a good Galaxy S24 Ultra screen protector on your phone right away.
Samsung Requirements To fix this issue on Galaxy S25 Ultra. This is a non-negotiable for a $1,200+ smartphone.
Better dimming options
As more and more research continues to pile up, it’s clear that PWM dimming on displays and LED bulbs is causing health problems. Since I started writing about this issue almost two years ago, I have been able to help many people by recommending smart phones and light bulbs to relieve the headaches they are experiencing every day. .
Unfortunately, Samsung is one of the worst offenders of flickering displays. Those displays are only getting tougher and more cumbersome every year as companies obsess over making them brighter and brighter. The solution is remarkably simple, but Samsung has so far refused to talk about it or make any tangible changes to improve the long-term health of its customers.
American consumers, in particular, have almost no Flickr-free options to choose from since Samsung, Google, and Apple are now equipped with every phone they make. Samsung has a real chance to set things right with the Galaxy S25 series and take the lead on eye health as the world’s largest smartphone maker.
If companies like OnePlus, Nothing, Vivo, Xiaomi, Oppo, and many other brands can do it, so can Samsung.
Don’t forget the fans
The last issue is the least serious but the one that bothered fans the most. At launch, the Galaxy S24 Ultra’s display was smaller than previous Galaxy flagships.
I praised the display’s more realistic colors in my Galaxy S24 Ultra review, and while Samsung did a great job of improving the colors to make them more realistic, the company apparently forgot that some of its Consumers love vibrant, highly saturated colors.
Samsung released a patch about a month after the release of the S24 Ultra to address the issue and provide a dynamic slider for those who wanted bolder colors. Hopefully, the company won’t forget this option when it launches the Galaxy S25 Ultra soon.
