Samsung's version of Android 15, ONEUI 7 is missing in action for the Samsung Galaxy S24 Ultra, and other S24 series phones, and other models from previous years. Currently the Samsung Galaxy S25 series phones (S25, S25 Plus, and S25 Ultra) have OneUI 7, but for now that's it and it could be as late as April according to the latest leaks, before other phones get it which is not cool!
