dj10fld Hello,
I don't know what information you read, but here is the only information I can find.
The S10 is able to record videos in 8K 30fps.
It is perhaps complicated to the S10 to make him play videos in 8K 60/90/120fps (I do not know with which video you tested, you do not give any information).
After, it doesn't matter if it's with a snap or an exynos, it seems to be able to play 8K videos : https://www.techwalls.com/exynos-9820-snapdragon-855-processor-comparison-samsung-galaxy-s10/
But it is not specified the number of frame per second compatible, so that's where your problem is.
Do a test with a 30fps video to see.
