Samsung has officially expanded its Android 17-based One UI 9 beta to the Galaxy S25 series and 2025 foldables, while separate reporting confirms that testing is now live for the Galaxy S24 family in several markets.
Samsung is widening One UI 9 testing beyond the Galaxy S26 series, giving more Galaxy owners early access to its next major Android software update.
The company confirmed on 1 September that the Galaxy S25, S25+, S25 Ultra, S25 FE, Galaxy Z Fold7 and Galaxy Z Flip7 are joining the beta programme in India, South Korea, the UK and US. Samsung launched One UI 9 testing with the Galaxy S26 series in May.
The Galaxy S24 series was not included in Samsung’s September announcement. Android Authority reported on 2 September that the first One UI 9 beta is live for the Galaxy S24, S24+ and S24 Ultra in the US, India and South Korea.
Which Galaxy Phones Are Getting the One UI 9 Beta?
Samsung has formally added six devices to the September expansion: the Galaxy S25, S25+, S25 Ultra, S25 FE, Galaxy Z Fold7 and Galaxy Z Flip7.
Eligible users can register through the Samsung Members app in supported markets. Samsung notes that availability can vary by country, device model and network provider.
One UI 9 is based on Android 17 and brings changes across customisation, accessibility, security and Samsung’s AI-powered software experience. Expanding the beta to 2025 hardware also gives Samsung a larger test pool before stable software reaches more existing phones.
What Is Happening With the Galaxy S24 Beta?
Galaxy S24 owners are also beginning to receive One UI 9, although Samsung has not formally added the 2024 flagships to its published September beta list.
Android Authority reported that the first beta is available for the Galaxy S24, S24+ and S24 Ultra in the US, India and South Korea. The download is roughly 3.6GB and includes the August 2026 Android security patch.
That makes the S24 situation different from the S25 rollout. Samsung has officially confirmed S25-series eligibility, while S24 availability is currently established through live beta reports rather than a matching Samsung newsroom announcement.
For S24 owners in supported regions, users who see the One UI 9 banner in Samsung Members can enrol and download the beta. Availability may still differ by market and carrier.
What Does One UI 9 Add to Galaxy Phones?
One UI 9 introduces interface and security changes alongside new personalisation, accessibility and AI features.
Samsung’s original beta announcement highlighted expanded tools in Samsung Notes, more customisation options and changes designed to make privacy and security controls easier to understand.
Samsung has since added more features to Galaxy S26 beta builds. My FanCam uses AI to keep a selected person in focus and can automatically reframe footage for different aspect ratios. Now Brief has gained customisable cards and security information, while Now Nudge offers more contextual suggestions across supported apps.
Samsung’s Galaxy Z Fold8, Z Fold8 Ultra and Z Flip8 also launched with One UI 9 in July, showing that the software has already moved beyond beta on new hardware.
When Will Stable One UI 9 Arrive?
Samsung has not announced a confirmed stable One UI 9 release date for the Galaxy S26, Galaxy S25 or Galaxy S24 series.
Forbes reported that firmware tracker Tarun Vats had spotted builds believed to be stable One UI 9 releases for the Galaxy S26 series on Samsung’s servers. Those builds indicate development is advancing, but they do not establish an official rollout date.
Galaxy owners who prefer stable software may want to wait because beta releases can contain bugs or app compatibility problems. Those who want early access can check Samsung Members for eligibility.
The next key milestone will be Samsung’s confirmation of when stable Android 17-based updates begin reaching existing Galaxy devices.
