Just stopped by my local AT&T store. They had a pink S20 and a blue S20 Plus on display. Unfortunately, the phones were turned off and charging. The store reps said they could not turn them on. I really wanted to check some of the settings, particularly if there was a way to turn 120hz display on full-time, given today's news that it's 'dynamic' like the awful default OnePlus 7 Pro and Pixel 4 implementation -_-
Phones look very sleek and slim. Just as the dimensions would suggest, they are ever so slightly smaller in the hand than their S10 predecessors, though they feel almost exactly the same. Like several YouTubers, I thought the look and feel of the extra slim metal chassis on the side is less comfortable than the more rounded ones of the S10e, and even the S10.
The display is indeed a bit less curved than before. However, those like Max Weinbach claiming it's the same "2.5D" glass as on the Pixel 4 are a bit off the mark. It is ever so slightly more curved than that. However it is noticeably less curved than on the S10.
