  • Samsung has begun rolling out the first One UI 8 beta, starting with the Galaxy S25 series.
  • Surprisingly, the first beta is available in its home region of South Korea and the US, UK, and Germany.
  • Users interested in the beta program must sign up through the Samsung Members app.

Samsung released the first One UI 8 beta late last month for Galaxy S25 devices, giving users a glimpse of what’s coming with their Android 16 update. Now that Google has also released stable Android 16, Samsung has gone ahead and released One UI 8 beta 2 to users.

The second One UI 8 beta build for the Galaxy S25 series (h/t Tarun Vats) is 1.2GB in size over the first update, and has the version number S938NKSU4ZYF3/ S938NOKR4ZYF3/S938NKSU4BYF3, depending on the region. This update is rolling out to users in South Korea.
