According to a recent survey on Reddit, screen problems in the Samsung Galaxy S24 series are still increasing. It turns out that some users have noticed a grainy texture on their screens, particularly visible on dark and gray backgrounds. According to information from Reddit, this problem seems to be prevalent among users of the Samsung Galaxy S24, Galaxy S24 Plus, and Galaxy S24 Ultra models. We have checked the Galaxy S24 Ultra, which we analyzed to see if we also noticed this issue, but we did not observe any grainy texture.
One Reddit user claims to have put their phone under a powerful 400x OM microscope to examine the Galaxy S24 Ultra and found a significant drop in pixel brightness uniformity at 10% brightness compared to 50%. Due to this lack of uniformity, the user perceives the absence of some pixels, making the screen appear grainy. This problem is known as the Mura effect or “blurring” and is a common defect in LCD and OLED screens. In the Reddit comments, it can be read that many customers have received a new phone from Samsung, but others have been denied and had to escalate the issue.
This is not the first problem Samsung has faced with screens in the S24 series. Recently, reports have emerged on Reddit complaining about the faded Vivid Color profile in the Galaxy S24 Ultra. Many users believed it was a software issue, but Samsung strongly stated that it was a deliberate design choice. However, there is information that a future update will introduce a slider allowing users to adjust color profiles to their preferences.
Posts have also appeared on Reddit about certain models displaying three horizontal stripes on the screen at lower brightness. Usually, this is caused by the phone not being able to generate enough color shades to smoothly blend them at lower brightness, resulting in the appearance of slightly darker lines.
Fortunately, this problem seems to affect a smaller number of users compared to the grainy texture issue. The appearance of stripes on the phone screen is not a new phenomenon and can be quite common, but if they are distinct or appear all the time, it may indicate screen damage.
Lastly, there are also complaints about excessive edge enhancement during the viewing of gradient images. However, opinions on Reddit suggest that this is more likely a software issue that can be resolved soon.
The Galaxy S24 series has many enhancements and is one of the best phones we have tested. However, the fact that it is not the first reported screen problem is concerning. We hope that a solution is being worked on and that all affected individuals will be able to replace their devices. We will keep you informed of any updates.
