Samsung is one of the leading smartphone brands in the world by now, and it's been steadily increasing support for its devices. Back in 2022, it chose to make all new smartphones supported for four years of OS updates and five years of security updates. Thus, devices as old as the Galaxy S24 — which released at the start of 2024 — will all be supported through to 2030 or longer. (Fun fact: The S24 was originally planned for four years of software upgrades, but Samsung's community moderators have confirmed that it's sticking around for the full seven.) The Galaxy S23, on the other hand, has already ended software updates, with security updates coming to a close in February of next year.
