Samsung is expanding its One UI 9 internal beta testing to include the Galaxy S23 FE, Galaxy M34, and the Galaxy Z Fold 6 and Z Flip 6. Firmware tracker Tarun Vats confirmed these additions, noting that a Galaxy A37 build has also appeared on Samsung’s servers. This development signals a broad testing phase across multiple hardware generations ahead of the official launch at the Samsung Unpacked event in late July.
Which Samsung devices are currently testing One UI 9?
The confirmed testing lineup for One UI 9 now spans a wide range of hardware. According to data from Tarun Vats, the devices include the Galaxy S23, S24, S24 FE, S25, and S26. The testing also covers the A-series with the A35, A56, A57, and A37, as well as the M34 and the 2024 foldables, the Z Fold 6 and Z Flip 6.
Samsung is currently managing development for four different generations of flagship phones simultaneously. This massive rollout includes four A-series devices, one M-series budget model, and two recent foldables. The scale of this testing suggests a synchronized software push across the entire Galaxy ecosystem.
What are the main differences between One UI 8.5 and One UI 9?
While One UI 8.5 focused heavily on visual overhauls and AI integration, One UI 9 targets system refinement and accessibility. One UI 8.5 introduced a major visual change by splitting the Quick Panel’s brightness, volume, and media controls into separate, resizable sliders. It also brought AI-driven features like AI Call Screening, real-time voicemail transcripts, and a Bixby experience powered by Perplexity.

In contrast, One UI 9 introduces several specific accessibility tools. These include a combined TalkBack update that merges Samsung and Google screen-reader tools into a single system. Users will also see a new “Text Spotlight” floating zoom tool for easier reading and a high-risk app detection feature. This new security measure warns users and blocks the execution of unsigned or suspicious applications.
Comparing One UI Features
| Feature Category | One UI 8.5 Focus | One UI 9 Focus |
|---|---|---|
| Primary Goal | Visual overhaul & AI | Refinement & Accessibility |
| Key Tools | AI Call Screening, Creative Studio | TalkBack merge, Text Spotlight |
| Security/UI | Quick Share (AirDrop compatible) | High-risk app detection |
How is the Galaxy S26 beta program progressing?
Samsung has maintained a consistent two-week release schedule for the Galaxy S26 beta program. The rollout began with Beta 1 on May 13, followed by Beta 2 on May 26. The third beta, released on June 16, shifted focus toward system stability rather than introducing new features.

The June 16 Beta 3 update addressed nine specific technical issues. These fixes included resolving camera preview cropping and inaccurate 30x zoom focus. Samsung also corrected bugs regarding lock screen weather and battery widgets, S Pen swipe gestures, and a scrolling bug within the My Files app. Additionally, the update addressed random reboots during video streaming and screen glitches during incoming calls.
When will the stable One UI 9 update be released?
The official launch of One UI 9 is expected at the Samsung Unpacked event in London at the end of July. The stable version of the software is slated to debut on the Galaxy Z Fold 8 series. After the foldables receive the update, Samsung will roll it out to other flagship and recent foldable devices.
Older devices will follow a different timeline. The Fan Edition (FE) and A-series devices are scheduled to receive the One UI 9 update later in the rollout cycle. This tiered approach ensures that the newest hardware receives the most stable version of the software first.
