Samsung has opened the beta program for One UI 9, its Android 17-based software, exclusively for the Galaxy S26, S26+, and S26 Ultra as of May 12. The public test rollout comes just weeks before the company’s summer Galaxy Unpacked event in London on July 22, where it is expected to announce the stable release alongside a new foldable form factor.
What’s Inside the One UI 9 Beta for Galaxy S26
The early build, available now through the Samsung Members app in Germany, India, Korea, Poland, the U.K., and the U.S., is not a radical redesign. Instead, it layers practical refinements onto the core Android 17 experience. The most immediate change is in the Quick Panel, where users can now independently adjust the layout and size of brightness, sound, and media controls. This means you can, for example, keep the brightness slider large while shrinking the volume control, tailoring the interface to what you actually reach for most often.
Samsung Notes picks up decorative tape elements and additional pen styles, while the Contacts app gains a direct link to Creative Studio for crafting profile cards. The latter requires the separate Creative Studio app, a Samsung account, and an active internet connection, and its availability varies by region.
On the accessibility front, three updates stand out. Mouse Key, the feature that lets you control the cursor with a numeric keypad, now has adjustable speed settings. Samsung has merged its own screen reader functions with Google’s into a unified TalkBack package, removing duplication. A new Text Spotlight option magnifies selected text in a floating window, a small tweak that could make a big difference for anyone with low vision.
The security headline is an expanded suspicious-app protection system. Samsung says policy updates can now identify potentially dangerous apps, warn the user, block installation or execution, and even recommend removal. It’s a policy-driven layer that sits on top of Android’s built-in protections and Samsung’s monthly security patches—important for personal data but not a replacement for enterprise mobile-device management controls.
Who Stands to Benefit—and Who Should Wait
For Galaxy S26 owners, the beta is a chance to kick the tires on Android 17 months before the stable release. Enthusiasts with a spare device or a high tolerance for instability can enroll now. But make no mistake: beta software can break banking apps, cause Bluetooth dropouts, and degrade battery life. Back up your data first, and accept that some carrier-specific features may not work. This is not the build to install on a phone you rely on for two-factor authentication or business travel.
Owners of older Galaxy phones—including the S25, Z Fold 6, and A-series models—must exercise patience. Samsung has not published a device eligibility list for the final One UI 9 update. Reports from Gizmochina hint at a wide rollout spanning S, Z, A, M, and F series phones, but Samsung’s update policy math isn’t binding. Regional carrier approvals, hardware limitations, and product-specific support terms will gate the final list. Until Samsung issues model-by-model notices, any claimed eligibility is provisional.
IT administrators managing fleets of Samsung devices should view the beta as a preview, not a pilot. The suspicious-app mechanism could eventually feed into enterprise security policies, but in its current state, it’s untested outside Samsung’s lab. Wait for the stable release and test it against your MDM solution before pushing it to end users.
For everyone else, the July 22 Unpacked event is the real milestone. Samsung has teased “A New Shape Unfolds,” and the animated invitation suggests a wider, shorter device silhouette than current Z Fold phones. Trade-in offers and a no-cost pre-reservation for the next Galaxy device are already live, with a $30 Samsung Credit and up to $1,230 off with an eligible trade-in. That’s a tangible incentive if you’re already considering an upgrade.
The Road to One UI 9: From Android 17 to Galaxy Unpacked
Samsung’s One UI beta programs typically begin with the latest flagship before trickling down to older devices. The Galaxy S26 series, launched earlier this year, is the natural starting point for Android 17. Public betas allow Samsung to gather telemetry on battery optimization, app compatibility, and carrier integration—critical for a software release that will eventually ship on millions of phones.
The London Unpacked event on July 22 (9 a.m. EDT) is the probable launchpad for the stable One UI 9, though Samsung has not explicitly confirmed this. Historically, new foldables debut at summer Unpacked events, and this year’s tagline points to a design departure. Leaks suggest a wider folding phone reminiscent of the discontinued Microsoft Surface Duo, potentially beating Apple’s long-rumored foldable to market. If the hardware unveils with One UI 9 out of the box, the software’s public rollout to older devices could follow within weeks, similar to last year’s pattern.
The security controls in this beta reflect a broader industry push. Google has been hardening Android against sideloaded threats, and Samsung’s policy-based approach mirrors Microsoft’s SmartScreen in Windows—a recognition that end users often click past warnings. For Windows users who juggle both platforms, this is a familiar concept: an automated guard that steps in when an app looks risky, without forcing you to become a security analyst.
How to Get the Beta or Prepare for the Stable Release
If you own a Galaxy S26, S26+, or S26 Ultra in a supported country, head to the Samsung Members app on your phone. The beta enrollment banner should appear at the top of the home screen. Tap it, follow the prompts, and the update will arrive over the air. Again, back up your device before installing, and plan for the possibility of rolling back to the stable channel if something critical breaks.
If you don’t own an S26 but want the latest Samsung hardware, the pre-reservation window is open now on Samsung.com. It costs nothing to sign up with your email, and it locks in a $30 credit toward the next device. Combined with trade-in values up to $1,230, this is currently the most affordable path to the S26 family or whatever foldable Samsung announces on July 22. The pre-reservation does not commit you to a purchase, so there’s little downside.
For those holding onto a Galaxy S25, Z Fold, or A-series phone, monitor Samsung’s newsroom and the Members app for rollout notices. Bookmark the official Unpacked page on Samsung’s site for a livestream of the July 22 event—TechRadar will also be on the ground with hands-on coverage, which can give you a clearer picture of whether the new foldable form factor is worth waiting for.
Looking Ahead: Foldables, AI, and the One UI 9 Rollout
Samsung’s July event will likely dominate the tech news cycle. Beyond the foldable tease, Galaxy AI is expected to be front and center, with new AI-powered features integrated into One UI 9. The company has also hinted at its Android XR Glasses, which could tie into the wearable ecosystem alongside new Galaxy Watches and Buds.
For Windows users who live in the Samsung ecosystem, the One UI 9 beta is more than a phone update—it’s a signal of where cross-device integration is heading. Samsung’s partnership with Microsoft on Link to Windows already bridges Galaxy phones and PCs, and a security-focused Android 17 could make that handshake even more reliable for notification syncing, file sharing, and app mirroring. Keep an eye on the stable release and, if history holds, a fall rollout that brings these improvements to a wide range of Samsung devices.
