It is rare for a smartphone to start without glitches. Of course, we talk about it a little more when it comes to Apple or Samsung.

In the last few days, according to Android Central, several users have reported that the Galaxy S24, S24 Plus and S24 Ultra's screen is experiencing a strange “grainy” issue. This problem would be pretty massive, and we're already talking about a “grainygate” (like the iPhone 4's antennagate).

“I see that some areas of the screen are darker than others, almost like a gradient.”

An initial message from a Galaxy S24 user mentions the presence of “grain” on the S24 screen when applications or other content is displayed on a dark background. Several Galaxy S24 owners quickly mentioned a similar problem: “I see certain areas of the screen are darker than others, almost like a color gradient.” This problem shouldn't exist. “.

In another Reddit thread, users reported that strange horizontal stripes appeared on the Galaxy S24's screen at low brightness. The problem only occurs when the screen only displays one color. The problems reported by users could be caused by a phenomenon called “Mura” on the screen. Simply put, each pixel struggles to maintain the same brightness as the surrounding pixels. This is a fairly common problem with VR headsets like the PSVR 2.

The phenomenon is only visible when the Galaxy S24's screen brightness is below 10%. When testing on our end, we found that all subpixels were affected by this “grain”, but the red and blue pixels were more affected.

Additionally, Samsung will roll out a software update that adds the ability to change the screen's vibrancy. This feature allows users to choose between brighter, more saturated colors or more natural, neutral colors. As a reminder, vibrancy corresponds to the intensity of the colors displayed on the screen. It is unknown if this has anything to do with this “Grainygate”, but this update can be seen as a proactive response to user feedback.

Currently, Samsung has not officially responded to this “Grainygate”. It is imperative that the Korean manufacturer work to identify the issue in question, its significance, and the corrective measures to be taken.
