I have been noticing significant motion smearing on my S21 Ultra. I did a side by side comparison to a OP7tpro to make sure that it was not my eyes playing tricks on me. I also tried with a friend's S21 Ultra and it yielded the same result so I know it's not a random defective unit on my side. I notice the issue prevalent on videos that are rendered with the HEVC codec. I really hope Samsung has an update that fixes the issue. The whole point of getting an Ultra phone was for a no compromises phone and this hasn't been the case. Do any of you guys also face the same problem or have a solution. I tried lowering the screen resolution, the refresh rate, turning on and off video enhancer, blue light filter, and even factory reset my phone once.

Maybe you can focus on the character outlines when they are in contrast with the white background
This is a 30fps video. I watched it in 720p.
My screen resolution was set to 720p and I couldn't notice any blurring.
I'll check again, try different resolutions, and report back.
