Honestly, given that it's getting it's extra display size over the Note 9, (6.9" vs 6.4"), from a taller, with less bezel format... I have to wonder if viewing movies/videos will be much, if really at all, different between the two.
When I'm watching videos I tend to be more focused in the middle'ish area of the screen, not the left or right areas.
Makes me think that the viewing experience between the two devices will be the same.
The Note 10+ is wider than the Note 9, the same height, so I'm thinking that phone will provide a better experience over the Note 9 than the S20 would.
Thoughts from folks who have watched a lot of video on both the Note 9 and 10+?
