According to a recent survey on Reddit, the Samsung Galaxy S24 series screen problems are far from over. It seems that some users are finding that their screens have a grainy texture that is particularly visible on dark and gray backgrounds.
According to the Reddit post, this issue appears to be widespread and appears to be affecting customers using the Samsung Galaxy S24, Galaxy S24 Plus, and Galaxy S24 Ultra models. We checked the Galaxy S24 Ultra we tested to see if we had the same problem, but we couldn’t detect the grainy texture.
A Redditor claims to have put his phone under a powerful 400x OM tool (a type of microscope) to check his Galaxy S24 Ultra and found that the brightness uniformity between pixels was massive at 10% brightness compared to 50% decreased. Due to this lack of uniformity, it appears to the user as if some pixels are missing, causing the screen to appear grainy.
This problem is known as the Mura effect – or “haze” – and is a common fault with many LCD and OLED screens. There are comments in the Reddit post that many customers were able to get a replacement phone from Samsung, but others were denied a replacement phone and had to escalate the issue.
This isn’t the first problem Samsung has had with its S24 series screens. Recently, there were reports on Reddit complaining about the Galaxy S24 Ultra’s lackluster Vivid Color profile. Many users thought this was a software issue, but Samsung insisted it was a conscious design decision. However, it has been reported that a future update will implement a slider that will allow users to better adjust the color profiles to their preferences.
There were also posts on Reddit that certain models were showing three horizontal bars on the display when the brightness was low. These usually occur because a phone is unable to produce enough tones to easily smooth them out at lower brightness, resulting in lines with a slightly darker tone.
Luckily, this issue seems to affect fewer users than the grainy texture issue. The appearance of bars on a phone screen is not a new phenomenon and can be quite common. However, if they are excessively visible or appear constantly, it may indicate a bug in the phone’s screen.
Finally, there seems to be some complaints about excessive banding when viewing gradient images. However, there are claims on Reddit that this is more of a software issue that may be fixed soon.
The Galaxy S24 series features some great improvements and is one of the best phones we’ve tested. What’s concerning, however, is the fact that this isn’t the first reported screen issue. Hopefully a solution is being worked on and everyone affected can have their devices replaced. We will keep you informed of any updates.
