All three Galaxy S26 models are eligible. Those who are interested can sign up through the Samsung Members app. The official One UI 9 changelog has now been made available. It mentions some of the new features and improvements that the next major firmware update brings. This includes a more customizable Quick Panel, Samsung DeX improvements, a new Tape feature in Samsung Notes, and more.Samsung should eventually make the One UI 9.0 beta program available for devices other than the Galaxy S26 series. That may take a few weeks, though. The company will likely release the stable One UI 9.0 update in the second half of this year, once the new foldable phones are out.
