Samsung’s next-generation major OS, Android 16-based One UI 8, has been released, starting with the Galaxy S25family, and will expand to more devices over the coming months. Since rumors have already shed light on the ongoing internal development of One UI 8.5, now the first internal build is out on test servers.
Well, for years, Samsung had usually followed up with a tradition of releasing additional incremental updates, One UI x.1 and One UI x.1.1.
But this time, things have been changing certainly, as the company decided to bring up a significant leap and planned to introduce One UI x.5 in the form of One UI 8.5 right after a major gap since the One UI 2.5 version.
Despite hearing certain leaks and rumors regarding One UI 8.5’s development process that is perhaps going on behind closed doors, suggesting that One UI 8.5 will be the next stop. Meanwhile, a reliable tipster, Tarun Vats, on X, shared a post that claimed that the first-ever One UI 8.5 test build for the Galaxy S25 series has been spotted on Samsung’s internal test servers.
Specifically, the newest One UI 8.5 internal test build for the Galaxy S25 series carries the S93*BXXU5CYIA version number.
Well, surprisingly, in any case, if this report is to be believed, then it appears like Samsung has begun the development process of the upcoming One UI 8.5 build for the current flagships, the Galaxy S25 family, and also, the newest version is supposed to be powered by Android 16, though.
Nevertheless, the next-generation Galaxy S26 series is already set to arrive during January’s Galaxy Unpacked event next year; thus, it’s quite possible that the upcoming flagships might debut with the Android 16-powered One UI 8.5 version.
