Samsung hasn’t closed the One UI 8.5 beta program, making it the longest software testing campaign to date. This is not an achievement to take proud at, but a matter of shame for the world’s largest smartphone-selling company.

The program opened on December 7 for the Galaxy S25 series. The first beta was released on the same day of enrollment, and the company has expanded the number with 9 more betas to date. These updates introduced a couple of new features and UI upgrades, as well as bug fixes for the participating models.

Later on, a couple of other phones, such as Galaxy Z Fold 7/Flip 7, as well as previous-gen flagships such as S24 and S23 series, also joined the program.

Past leaks and rumors had it that the beta program would conclude on April 30th with a stable release for Korean users. This speculation included expansion to global users in early May.

However, none of that happened, making the One UI 8.5 the longest beta program the company has ever opened. The total length of the test has reached 4 months and 26 days, and the counter is still on.

Still, Samsung hasn’t announced a release date for the final build, but it could get it done before mid-May. However, nothing is certain from this point of view. For example, past leaks regarding the rollout have been proven false, and we will only believe it when Samsung actually releases the update and closes the program.

If you are a Samsung Galaxy user waiting for the next software update, you are not alone. Many people (thanks to the unconfirmed release date) have been checking their phones daily for the One UI 8.5 stable version.

Let me clear everything for you. Here’s a simple and clear update on where things stand with One UI 8.5 and the upcoming One UI 9 beta.

One UI 8.5 stable rollout:

Almost here. Samsung had planned to roll out the stable One UI 8.5 update on April 30 in South Korea for the Galaxy S25 series. But it got delayed by a day or two because of the Labour Day holiday on May 1.

As per latest information, the update hasn’t started yet. However, reliable sources say it should begin very soon, most likely on or around May 4, first in South Korea, followed by more markets including India, US, Europe, and others.

The Galaxy S25 series (S25, S25+, S25 Ultra, etc.) will see it first, as the S25 series has been in beta testing program for months. You can expect the rollout to spread fast in May to more devices. The Galaxy S24 series, recent foldables (Z Fold 7 / Z Flip 7), and many mid-range models like A-series should follow in the next few weeks.

To be excited, the One UI 8.5 update brings smoother animations, better AI features, easier sharing with iPhones, and some nice quality-of-life improvements.

One UI 9 Beta:

Still a few weeks away. Samsung is wrapping up the One UI 8.5 beta program, and the company has already started early internal testing for the next big version – One UI 9 (based on Android 17). A few S26 users have already installed and tested the leaked One UI 9 internal beta version.

The public beta (where regular users like you can try it) is expected to open in late May or early June 2026. It will probably start with the latest flagships first, the Galaxy S26 series. The full stable One UI 9 is likely to come around August 2026, probably launching with the new Galaxy Z Fold 8 and Z Flip 8.

While you are waiting for the notification to hit your phone, make sure your phone is backed up and has enough battery and storage.
You can continue checking the Samsung Members app, that’s where beta invites and update news usually appear first. If you are on a supported device, you might even get a notification soon.

Stay tuned, and I will keep you posted if anything changes. Which phone do you have? Drop a DM on our X handle @thesammyfans, and I can tell you when to expect your update.

Samsung Galaxy Tab S11 and Tab S11 Ultra tablets have started to receive the One UI 8.5 Beta 3 update. The fresh build introduces new AI features and DeX improvements.

One UI 8.5 Beta 3 for the Galaxy Tab S11 series can be identified via PDA build version ending with ZZD7. The release also brings April 2026 security patches.

The highlight is the continued push of AI features borrowed from the Galaxy S26 lineup.

Call Screening gets further improvements, making it more reliable in filtering unknown calls and handling them smoothly in the background.

Creative Studio, another AI-powered tool, sees several fixes. Issues like overlapping elements, incorrect sizing while creating stickers, and glitches when working on invitations or sketches have been cleaned up.

Samsung DeX also gets attention in this beta. A bug affecting the Cmd + F shortcut in Guest mode has been fixed, and settings like font size and screen zoom now save properly in DeX Guest mode.

There are also stability improvements when switching between standalone DeX and Second Screen mode, which should make multitasking more consistent.

Lastly, there’s a minor but useful fix for the Weather app, resolving an issue that prevented users from modifying notification settings.

Samsung just pushed the latest One UI 8.5 Beta update for Galaxy S23 FE and S24 FE. The former is getting the second Beta build, while the latter is picking up the third release.

The company has included crucial bug fixes, covering calling, proximity sensor, display and camera. In particular, the Galaxy S23 FE is seeing the addition of the Privacy Alerts feature, which gives users better visibility into how apps access sensitive data.

Alongside the new addition, Samsung has focused heavily on stability, addressing several long-standing issues that affected daily usability, especially around calls, camera performance, and system reliability.

The update fixes a frustrating bug where incoming calls sometimes showed a delayed or black screen, while also correcting inconsistent proximity sensor behavior during active calls.

Camera improvements include a fix for green line artifacts appearing during 4K HDR video recording in certain apps, a problem that had been reported by beta users recently.

Samsung has also resolved Bluetooth crash issues and improved multi-touch accuracy after using accessibility zoom, making the overall experience smoother and more consistent across different usage scenarios.

Samsung has rolled out the 2nd One UI 8.5 Beta for the Galaxy Z Fold 5 and Galaxy Z Flip 5, carrying build version ending in ZZDN. The latest software update focuses largely on bug fixes and usability refinements.

Stable One UI 8.5 may begin rolling out this week, with the Galaxy S25 series awaiting as the first candidate. As for the older phones and foldables, Samsung may kickstart the update distribution by the end of May 2026.

One of the more noticeable improvements targets call performance. Samsung has addressed low speakerphone volume and poor audio quality issues that users experienced during calls, particularly in driving scenarios.

The firmware update also fixes a frustrating bug where saved contacts failed to display their image and details when placing calls. This should restore a more consistent and expected calling experience across the system.

Samsung has also corrected a subtext error in the “Show brief pop-ups even when screen is off” setting. While minor, this fix improves clarity within system menus and reduces confusion during customization.

Another fix resolves a screen transition glitch that occurred after saving a contact while a folder was closed.

Lastly, the company has fixed an operational error tied to launching the Camera app. This should eliminate occasional hiccups and ensure the camera opens reliably when needed.

Here’s the 2nd One UI 8.5 Beta changelog for Galaxy Z Flip 5 and Fold 5

• Improved low speaker phone volume and poor call quality during driving
• Fixed an issue where contact image and information were not displayed when making calls from saved contacts
• Fixed a subtext error under the “Show brief pop-ups even when screen is off” menu
• Fixed a screen transition issue after saving a contact while a folder is closed
• Fixed an operational error when launching the Camera app

After the Galaxy S23 series, Samsung pushed the One UI 8.5 Beta 2 update to the Galaxy A36, Galaxy A55 and Galaxy A35. The software is now available for Beta participants in India.

It is a cleanup-focused update, targeting a few noticeable annoyances from the first build. Users can identify the update via the PDA build version ZZDC/7/9, which also carries the latest April 2026 security patch.

The most important fix addresses Bluetooth behavior. Autoscan wasn’t triggering properly when users entered the Bluetooth menu, which could make device discovery feel broken.

Performance tuning is also part of this build, as spotted by Mohammed Khatri. Samsung has worked on reducing the lag when pulling down the Quick Panel, which should make everyday interactions feel smoother and more responsive.

On the UI side, there’s a fix for an issue where the message input field would overlap with the navigation bar. It’s a small bug, but one that directly impacts usability while typing.

Lastly, Samsung has patched System UI ANR (probably App Not Responding) issues that appeared after FOTA (firmware over-the-air) updates. This should improve overall stability and reduce random freezes tied to system processes.

Overall, Beta 2 doesn’t bring new features, but it tightens up performance and fixes some rough edges from the initial release.

One UI 8.5 Beta 2 changelog for Galaxy A36, A55 and A35

• Fixed an issue that Bluetooth Autoscan did not work when entering Bluetooth
• Improved the Sluggish/Delay when lowering the Quick Panel
• Fixed an issue that overlaps the message input window with the navigation bar
• Fixed System UI ANR issues after FOTA

Samsung’s One UI 8.5 Beta 2 update has started rolling out to the Galaxy S23 series. The latest software update carries the PDA version ZZDP, which brings fixes for key issues linked to the display, calling, camera, and more.

The update improves call reliability, addressing cases where the screen would turn black or respond late when receiving a call. It also fixes problems with the proximity sensor during calls, which could behave inconsistently.

Camera stability gets a boost too, with a fix for green line issues that appeared while recording 4K HDR videos in some apps. Samsung has now addressed it, so video recording should be cleaner.

One of the notable fixes targets the “green line” problem, but this isn’t the display defect some users worry about. Instead, it was a camera-related glitch that could show green lines while recording 4K HDR videos in certain apps.

On top of that, Samsung has improved Bluetooth stability to prevent crashes. The update also resolves a multi-touch issue that could occur when certain accessibility settings were enabled, making overall touch response reliable.

One thing that caught my attention is the continuity of security patch. Samsung should have included the May 2026 security patch. Instead, the second Beta retains the current security patch dated April 5, 2026.

Samsung is expected to wrap up One UI 8.5 Beta for the Galaxy S25 series, and prolong for older models such as the Galaxy S24 series.

The Korean company commenced the One UI 8.5 Beta Program in December 2025. The Galaxy S25 series was the first to join the Beta testing. March and April marked the testing activity’s expansion to more Galaxy lineups.

Samsung is said to start the One UI 8.5 rollout on April 30 in South Korea and on May 4 in the Global markets. Users of the Galaxy S25 series will shift to Stable version, while the testing will continue for older models.

Over the past couple of days, new Beta builds surfaced on the internet. The updates will be rolled out to the users of the Galaxy S24 series and the Z Fold 7 and Z Flip 7.

Beyond that, Samsung would also release new Beta updates for the Galaxy S23 series and mid-range phones that have joined the Beta Program in April 2026.

Samsung will be busy with the Galaxy S25 series in May 2026. However, we may see the update rolling out for select older flagships too, such as the Galaxy Z Fold 7 and Galaxy Z Flip 7.

Once the stability of the firmware is verified through the Galaxy S25 series, expansion should progress swiftly. The end of May and the beginning of June will be important for users who are awaiting the One UI 8.5 update.
