I'm not sure if I'm the only one in this boat, but I suffer from Vertigo. With the latest Samsung devices offering 120hz refresh rates, fast scrolling messes with my head. Which is why I chose the smaller a Note 20. (Also because it was a more comfortable size and I felt the 64mp photos looked better than the 108mp)
The dynamic refresh rate was a great idea. But an even better idea would be to allow for adjusting what the refresh rate cap could be. I feel like 90hz could be comfortable for me. As well as others that may have mild visual issues.
