Samsung’s Galaxy S21 is a few years old now, but it still holds up quite well against all the modern flagships, including the Galaxy S23 series. It arguably looks better than even the Galaxy S23 with its contour-cut design, and it’s easily one of the best-looking phones in 2023. It’s still qualified to receive Android OS and security updates directly from Samsung, so there’s no reason to upgrade unless you really want to upgrade to a new phone.
