Samsung has released One UI 9 Beta 5 for the Galaxy S26 series, pairing a batch of bug fixes with the August 2026 security patch for testers enrolled in the beta program. One UI is Samsung's custom software layer built on Android, and public beta programs like this one are a regular part of the company's release cycle, letting enrolled Galaxy owners test major versions ahead of the stable rollout.

Owners of the Galaxy Z Fold 8, Z Fold 8 Ultra, or Z Flip 8 are already running a stable version of One UI 9. Samsung introduced that build alongside its new foldables in July at Galaxy Unpacked in London. The Galaxy S26, by contrast, remains in the beta program, and Beta 5 is the latest step in that process.

Which phones are getting Beta 5, and where

Beta 5 is rolling out to the Galaxy S26, Galaxy S26+, and Galaxy S26 Ultra. The release began in South Korea, India, and the UK, and will expand to Poland, Germany, and the US as more testers receive it. Staggered rollouts that begin in a small set of markets, including Samsung's home market of South Korea, before widening are standard for One UI beta programs, and this build follows that pattern.

Key details of the build:

• Firmware version: S94xBXXU4ZZH6
• Download size: about 1.1GB
• Security patch: August 2026, covering 56 fixes
• Devices: Galaxy S26, Galaxy S26+, Galaxy S26 Ultra

Samsung issues monthly security maintenance updates for Galaxy devices, so bundling the current month's patch into the beta keeps testers at the same security level as stable users.

The release also arrives roughly a month later than planned. Beta 4 landed on July 14, and testers had been told to expect Beta 5 the following week. A Samsung Beta Operations Manager later apologized for the wait on the Samsung Community forum, saying the extra time went into final reviews and quality checks.

What Beta 5 actually fixes

This update is about fixing bugs rather than adding features. Samsung's changelog lists the following:

• Fixed an issue where the Settings app freezes or shows a white screen in some menus
• Fixed slow loading and a black screen when launching the camera widget on the lock screen
• Fixed the bottom floating bar not showing correctly in the Phone app
• Fixed a blank screen that appeared briefly when opening the recent files list in My Files
• Fixed an issue where 1×1 size shortcuts did not appear on the home screen bottom bar
• Fixed a misaligned or flickering preview screen in Video Editor and Photo Editor
• Fixed occasional screen flickering
• Fixed Wi-Fi connection errors and improved connection stability

There are no new features in this build. Most outlets that cover Samsung software, including SamMobile and Android Authority, describe Beta 5 as a cleanup release. Late-stage betas devoted entirely to fixes rather than new features are a familiar pattern in Samsung's software programs as releases approach stability.

Is this the last beta before stable One UI 9 for your S26?

Whether Beta 5 is the final beta remains unknown, and current reports point in two different directions.

Tipster Tarun Vats spotted two new firmware builds on Samsung's servers, one on the beta track and one on the stable track. Sammy Fans and SamMobile report that the beta build could be Beta 6, which would mean more testing before the stable release.

A separate tipster, Kailash, spotted a possible stable build for the S26 series. Sammy Fans reports this could indicate that Beta 5 is the final beta before the stable rollout.

Samsung has not confirmed either path. When a One UI beta program does end, Samsung typically makes that official through its Community forums and the Samsung Members app, so the server sightings will remain speculative until that word comes. Sammy Fans estimates the stable update could arrive by mid-September, possibly around the same time as the Galaxy S26 FE launch, but that timing is also unconfirmed. Both reports should be treated as leaks until Samsung says otherwise.

A quick timeline of the One UI 9 beta program

The Galaxy S26's beta program has progressed as follows since May:

• Beta 1: May 13, 2026 — launched in six countries at once
• Beta 2: May 26, 2026
• Beta 3: June 16, 2026
• Beta 4: July 14, 2026
• Beta 5: August 12, 2026

The first three betas arrived roughly two weeks apart. The gap widened to about four weeks between Beta 4 and Beta 5.

Older Galaxy phones are still waiting

No device older than the Z Fold 8 and Z Flip 8 has stable One UI 9 yet. Reports from Sammy Fans and SamMobile indicate that Samsung has started internal testing on the Galaxy S25 Ultra and Galaxy S24 Ultra, but a public beta for those phones had not opened as of mid-August. Owners of an S25, S24, or older model can expect to wait longer for the stable update — a sequencing consistent with Samsung's usual approach of bringing its newest flagships to a major One UI version first and extending it to older models over the months that follow.

Should you install Beta 5?

Beta 5 is still beta software and carries some risk. Keep these points in mind before installing:

• Back up your phone with Smart Switch first. Samsung itself warns that beta software can cause data loss.
• Skip this beta if you rely on sideloading apps. Some testers have reported that installing APK files does not work properly on this build.
• Note that going back to stable software later usually means a full data wipe, so treat this as a one-way step.
• If you are already enrolled in the Samsung Members beta program, check for the update under Settings > Software update.

What's next for Samsung's software

While the Galaxy S26 remains on the One UI 9 beta, Samsung has already started work on One UI 9.5. Tipster Fahad Ali Javed spotted the first build in early August, and leaked screenshots point to a glass-style design with shinier borders and softer shadows. SamMobile and Android Central report that One UI 9.5 is expected to debut with the Galaxy S27 series in early 2027, with a possible beta for the S26 arriving before the end of this year. Mid-cycle refreshes of this kind are an established part of Samsung's software cadence — One UI 5.1 and One UI 6.1 were earlier examples.
