Grainy/Sandy screen problem on the Galaxy S24 Ultra

[blackcemre]

Apart from faded colors on the screen, there is a sandy/grainy screen problem. There are many people affected by this issue on various forums. This problem is not caused by vivid mode. I don't know if this problem is hardware or software.

My problem was obvious at any brightness. The problem was evident in the dark gray parts. I took these photos in full light. The problem is evident in the dark gray parts in dark mode, creating a grainy appearance. It appears more, but at 50 percent brightness and below. The resolutions of the photos I uploaded are not bad, the screen looks exactly like this.

It is a hardware issue that cannot be fixed. If you have this defect return your phone.

Check out this post by a display scientist going in-depth on what's wrong and why you should return it.

Did changing the unit fix the issue?

I sent the new phone back without opening its box. I requested a refund. I can't take this risk anymore.

I received a replacement, but the screen was the same. They are all grainy

Is that dust under a screen protector? Or do you have a bright pixel already? 😬

I think this is a software problem/intention(?) that I noticed when comparing colours on Instagram with the iPhone. I like the way photos look on the S24 ultra (even better after today's update).

But what I noticed. I think Samsung's software is trying to make photos look even better by adjusting colours on the go. (I also see this on Google Gallery when I switch applications, the screen flickers a bit and the colours change).

On Instagram, the application has a black background that becomes a little grey after a few moments. Maybe the software doesn't always decide right whether  that thing we alctually have on display is  a photo or not. Sometimes it tries to update the colour of the UI.

After years of more saturated displays on the S21 and S23, I have to say that I like how photos look much better here, even if the colours on the icons are more washed out.

So if it is the case, we must return all unit and go to Honor maybe...
