Samsung has released One UI 9 Beta 5 for the Galaxy S26, S26+, and S26 Ultra, and this one is almost entirely about cleanup rather than new features. The update rolled out to India, South Korea, and the UK first, carrying the August 5, 2026 Android security patch, which reports say brings 56 individual security fixes on top of the usual beta bug fixes.
The changelog reads like a late-stage stabilization pass. Samsung fixed a Settings bug that could freeze the app or throw up a white screen, a lock-screen camera widget that sometimes launched slowly or showed a black screen, and a Phone app issue where the floating bottom bar wasn’t displaying correctly. My Files, Home screen shortcuts, the Video and Photo Editor preview windows, general screen flickering, and Wi-Fi connection stability all got fixes too. None of that is glamorous, but it’s exactly the kind of list that shows up when a beta is nearing the end of its cycle rather than the middle.
One detail makes this release more notable than a typical point update: Beta 5 arrived nearly a month after Beta 4, a longer gap than Samsung’s earlier betas, suggesting the company hit an unexpected delay before shipping it. That timing, combined with how narrow and specific these fixes are, points toward One UI 9 entering its final stabilization phase for the S26 series. Samsung hasn’t confirmed Beta 5 as the last one, and reports suggest one more beta build is still possible before stable software arrives.
There’s also an interesting wrinkle here. Samsung has already shipped stable One UI 9 on the newer Galaxy Z Fold and Flip 8, meaning the S26 series, despite launching earlier, is currently running behind Samsung’s own newest foldables on software maturity. No stable release date has been confirmed for the S26 yet.
If you’re enrolled in the beta, Beta 5 is worth installing mainly for the Wi-Fi and Settings fixes, plus the current security patch. If you’re waiting for stable software instead, the pace of these late-cycle fixes suggests the wait shouldn’t stretch much longer, though Samsung hasn’t put a date on it.
