Galaxy S25 series now receiving stable One UI 8.5 update
▼ Summary
– The One UI 8.5 update is currently rolling out in South Korea with build number CZDP, with a wider rollout expected later.
– Samsung typically releases four to five One UI beta builds over two to three months before the stable version.
– The One UI 8.5 beta program for the Galaxy S25 series was an exception to this pattern.
– Samsung opened the One UI 8.5 beta for Galaxy S25 in December 2025 and released ten beta builds.
– The beta phase for Galaxy S25 lasted five months before ending with the stable version release.
Samsung has begun distributing the stable One UI 8.5 update for the Galaxy S25 series, starting in its home market of South Korea. The firmware carries the build number CZDP, and a broader international rollout is anticipated in the near future.
Historically, Samsung’s beta programs for new One UI iterations involve four to five beta builds spread across two to three months before the stable release arrives. The One UI 8.5 beta program for the Galaxy S25 lineup broke from that pattern significantly.
The company initiated the beta phase for the Galaxy S25 series back in December 2025. Instead of the usual handful of builds, Samsung pushed out a total of ten beta updates over a span of five months. That extended testing period has now concluded, making the stable version available to users in South Korea first. Other regions should see the update roll out in the coming weeks.
