To download the One UI 8 Watch beta, you’ll need to have your Galaxy Watch connected to a Samsung device. From there, you’ll need to complete the process in the Samsung Members app.

Samsung's One UI 8 beta is now available for the Galaxy S25 series. The install process looks a little different now.

One UI 4, then, is Samsung’s Android 12 skin. Before the company can release it to the public, it needs to test the software through a beta program to iron out any bugs or issues.

Samsung is expanding its One UI 8 beta program, based on Android 16, beyond the Galaxy S25 series to include older models and select foldables.
