Samsung is yet to complete the Android 15-based One UI 7 stable update's rollout, which hasn't been without its issues, but we could see the Korean brand announce the One UI 8 beta program soon.
Last week, Samsung said the Android 16-based One UI 8 will arrive "this summer," and now, it has displayed a One UI 8 beta program banner in the Samsung Members app, telling users that they will be able to sign up for the One UI 8 beta program by tapping on this banner once the program is live.
Samsung Members app users received this notification in multiple countries, including South Korea, so expect to hear more about the One UI 8 beta program from Samsung soon.
