With the test build ready, the first One UI 9.5 beta version is planned to be offered to Galaxy S26 users before the end of November.
The beta program is expected to launch in limited markets, as in previous periods. The countries expected to receive the update in the first phase are:

Internal software prepared for Galaxy S25
Development steps were not limited to next-generation devices. A new test software build prepared for the Galaxy S25 Ultra also appeared on company servers. This record confirms that the flagship series released in 2025 officially began internal One UI 9.5 testing.
There is currently no public beta build for Galaxy S25 models. These devices are expected to join the beta process a few weeks after the Galaxy S26 series.
| Device Model | Testing Status | Expected Beta Period |

| Galaxy S26 Series | Public beta preparation (Build available on server) | Late November 2026 |
| Galaxy S25 Series | Internal testing stage | A few weeks after the S26 beta |
Stable release will be introduced with Galaxy S27 series
Based on the Android 17 operating system, One UI 9.5 includes interface improvements, new features, and artificial intelligence (AI) updates. The stable version will not be distributed directly to current models. Samsung will unveil the final One UI 9.5 version alongside the Galaxy S27 series, which will launch in early 2027. Following the release of the new flagships, the update will roll out to older devices, led by the Galaxy S26 and S25 series.
Whether the update will be tested in Turkey remains unclear. For now, it is planned for the regions listed above.
