I played with both s20 and s20+ for a while just now in pavilion SES. The 120hz screen is smooth but don't think it is a deal breaker for people to jump into it, especially those who own note 10+ or s10+.

Camera wise it's good but i find the 30x zoom somewhat useless. It's just the digital zoom that magnify the photos and end up being pixelated. The 2-3x zoom is still OK for me.

S20 is quite pocketable and I start appreciate smaller device after using big devices for quite some time.
