First, I have asked about this and this issue is noted regarding the grainy, dull and brightness concerns. After extensive testing across 2 years of MX models, i will first say that the Grainy display is a hardware issue. For those who are disappointed, upset or uncomfortable for this revelation, im sorry. We hope you still continue to support us. For those who had seen this conclusion coming, hopefully you are able to get your unit replaced. For me, SEA will replace my unit with a different batch a month or two down the line. Now i do not make this conclusion lightly, as i said earlier, the testing was done on MX units from 2022-2024. After noting the results, the grain can be detected on the following units. Galaxy Z Flip5, Galaxy S22 Ultra, Tab S9FE, S23FE, S23 Ultra, S24 Series, Tab S9, and Tab A9+. The Grain cannot be replicated on any of the lower end A series units and does not affect upon testing s23 or s23+ units. All Units were tested on the One UI version at launch, no modification was made to the display, QHD+ was set, with adaptive refresh on. The conclusion made here is that regardless of the OS running, the symptoms are identified. In addition screen burn, banding and other symptoms due to high brightness is not counted here.
