Samsung has already released five One UI 8.5 beta builds for the Galaxy S25 trio, and it appears the brand is still not done with the beta testing. Just recently, a new beta build was spotted on the test server, which could be the sixth for the S25 series. Now, if you’re wondering whether a new beta will cause a delay to the stable release or when the stable update will arrive, then stick to the post as we dig deeper to find those answers.
The One UI 8.5 beta program went live in early December for the Galaxy S25 series. At regular intervals, Samsung continued to push more beta builds to fix bugs and enhance the software experience. The Beta 3, in particular, brought some hope of a quicker, stable release, as the build reportedly had a near-stable smoothness with no obvious bugs. However, Samsung wasn’t convinced.
The fourth beta landed in early February, and then the fifth one arrived this week. While these builds primarily aimed to improve software smoothness and squash previously discovered bugs, they also introduced a couple of new features. Beta 4 added Direct Voicemail, and Beta 5 debuted AI-powered Bixby.
Samsung might release another One UI 8.5 beta soon, as a new build has just been spotted on the server (via Alfaturk) with firmware version ZZB7. This could go live next month as the sixth beta update for the Galaxy S25 series. We don’t know how many more are on the way. Last year, Samsung released seven One UI 8.0 beta builds before pushing the stable update. So, there could be one or two more beta builds for One UI 8.5 in the queue before we actually start receiving the stable update.
Samsung hasn’t announced when it will start rolling out the stable One UI 8.5 update. However, if past rollouts are anything to go by, we can expect the rollout to begin in late March 2026, starting with the Galaxy S25 series.

It’s been surprising to see that Samsung didn’t expand the One UI 8.5 beta program beyond the Galaxy S25 series. The brand has not confirmed if more devices will get the beta update. This could mean a direct stable release for other Galaxy models. That shouldn’t be concerning if Samsung quickly rolls out the One UI 8.5 update to its eligible devices. That seems more likely as the brand is reportedly gearing up to release the next-gen foldable devices with One UI 9.0 (Android 16) around July or August. Samsung would be looking to wrap up the One UI 8.5 rollout before that.
