Basically true of all smartphones, now. I recently saw a giant billboard for Samsung S22. I doubt Samsung has had 21 prior versions of the S line, but who knows. These phones all look the same and have had looked the same for a handful of years now.
Thanks for clearing this up. Last year I was shopping for used phones and looking at S8/S9, and getting very confused when I saw S21 starting to pop up. "How many of these did they make, anyway?"
Tangentially related, Reminds me of this: In Los Angeles there's a few very prominently displayed billboards at a shopping center for the Galaxy S4 that has somehow remained up [1]
