r/GalaxyS21 on Reddit: For those who own the S21+, how's the screen quality?
January 30, 2022 -
I'm coming from an S10+ and looking to upgrade to the S22+ (ultra is too big for me). Apparently the S22+ is going to have similiar screen quality as the S21+ in both 1080p and 393 pixel density. Only concern is going from a 1440p to 1080p. Apparently some people can't tell a difference and some people can. I did a quick search on here and it seems like a lot of had issues with the 21+ panel, color in accurancy, and some had upgraded to about 21 Ultra for better contrast and screen capability. But for those who have owned it for a while now, how is it holding up? Do you think it's worth the downgrade to the panel to upgrade the phone for 120hz?

I upgraded to a S21 Ultra from the S10+ but I played with a S21 (not the +, though) of a friend for a few days before getting the Ultra... I didn't feel a significant difference in image quality, nor was "seeing pixels”. I think the 120Hz upgrade is worth the resolution downgrade.

Why is the Samsung Galaxy S21 ultra screen size only 6.8 inches? Why not 7 inches or 7.2 inches? - Quora
Answer (1 of 2): Because anything over 7 inches is considered a small tablet. So they are trying to keep the screen size under the 7 number, in order to avoid the phone being classified as a tablet. A small tablet is 7 inches, a medium tablet is like 8–9 inches, a large tablet is 10, and ...
