Samsung could start its One UI 9.5 public beta programme earlier than expected, possibly before the end of November 2026. A new beta firmware build has reportedly appeared on Samsung's servers, suggesting that the company has already started testing its next major One UI update internally.
The development is good news for Galaxy users waiting to try Samsung's upcoming software features before the stable release. The first One UI 9.5 beta could arrive in the second half of November, instead of December, when Samsung started the One UI 8.5 beta programme last year.
However, Samsung has not officially confirmed the beta launch date yet.

Samsung One UI 9.5 Beta Firmware Spotted On Servers
According to the latest report, Samsung's first One UI 9.5 beta firmware has appeared on its servers with the build number S948BXXU6ZZK3. The firmware is reportedly designed for the Galaxy S26 Ultra and was spotted on November 4.
This is an interesting development because the first One UI 8.5 beta firmware surfaced on November 25 last year. Samsung subsequently opened its public beta programme on December 8.
The early appearance of the One UI 9.5 firmware suggests that Samsung could be further ahead with its internal testing this year. If development continues at this pace, the company could invite Galaxy users to test the new software sometime in the second half of November.
Some reports point towards a possible rollout window between November 16 and November 24, with November 23 also being discussed as a potential launch date. However, these dates are speculative, and Samsung has not announced an official schedule.
Which Samsung Phones Could Get The One UI 9.5 Beta?
As with previous One UI beta programmes, Samsung is expected to begin testing the update with its latest flagship smartphones.
The Galaxy S26 series could be among the first devices to receive the One UI 9.5 public beta, including:
The beta programme is also expected to expand to selected markets, including India, South Korea, the US, the UK, Germany and Poland.
Interested users will likely need to register through the Samsung Members app once registrations open. However, the exact list of eligible devices and countries is yet to be confirmed.

One UI 9.5 Could Be Based On Android 17
Samsung's upcoming One UI 9.5 is expected to be based on Android 17. While details about its new features are still limited, the update should bring interface improvements, software refinements and potentially new features to supported Galaxy devices.
The stable version is expected to arrive alongside Samsung's Galaxy S27 series in early 2027.
For now, Galaxy S26 users may not have to wait until December to try Samsung's next software update. The early appearance of the beta firmware is an encouraging sign, although the actual public rollout will depend on Samsung's testing schedule and remaining software fixes.
We will have to wait for an official announcement from Samsung to know when the One UI 9.5 beta programme will begin.
