Samsung’s latest Galaxy S24 series has been the subject of user complaints concerning the quality of its display. Reports have been surfacing from various sources such as Reddit and Samsung Community forums about a persistent grainy texture issue affecting all models in the series: the Galaxy S24, S24+, and S24 Ultra.
Customers have observed this defect predominantly on darker backgrounds, where it appears as though there is a static-like layer over the darker colors. One user, who experienced this on their Galaxy S24 Ultra, described it as akin to “a layer of unmoving static on top of the darker colors.” Further reports suggest that this isn’t limited to the S24 Ultra; similar patterns of grain have been reported across other models, including observations made on demo units in stores.
A deeper dive into users’ feedback indicates a possibility that this issue is beyond a simple software glitch and may well be rooted in the hardware. One user, after personally checking various S24 devices, claimed to witness the grainy texture and heard from Samsung that it is a hardware problem, which led to a return of their handset.
The complaint was further validated by a self-described “display scientist” on Reddit. This user, under the username “erodeloeht”, presented a technical explanation, attributing the problem to what is known in the display industry as a “mura”. This term refers to an inconsistent pixel pattern that becomes noticeable due to variations in subpixel intensity. The scientist pointed out that normally a “de-mura” technique is used to mitigate such discrepancies, but it seems Samsung may have overlooked this step.
To demonstrate the severity of the issue, the user reported comparing their Galaxy S24 Ultra at different brightness levels under a microscope and discovered irregular pixel distributions. In their analysis, competitors’ phones, like the Galaxy S23 Ultra and the iPhone 13, did not exhibit these mura effects, indicating this might be a unique problem to the S24 series.
Although this display issue may not affect every single unit, it raises concerns regarding quality control within Samsung’s latest flagship series. Users suspecting their Galaxy S24 series smartphone is affected by the grainy texture are encouraged to run tests by comparing their screens against solid color backgrounds and performing gradient tests available on websites like Test My Screen.
With the potential of a significant hardware flaw, customers experiencing this issue might have no recourse but to return their devices. As this story develops, those interested in the integrity of their smartphone’s display should stay alert for any official responses or solutions from Samsung to address this concern.
