Samsung’s next major Galaxy software release, One UI 10, could be a substantial overhaul rather than a routine update. This is based on a leak and on informed forecasts, not an official announcement. An insider claims Samsung is developing it with Google, that it is also referred to internally as Galaxy OS, and that the Google partnership includes paid third-party AI features. Samsung’s usual release pattern points to a stable version around July 2027. Based on Samsung’s existing Android upgrade promises, the Galaxy S24 and newer, recent foldables, and the Galaxy A16, A26, A36 and A56 should qualify. Samsung has said nothing official about One UI 10, and its plans could change before release.

What you need to know

  • On October 11, 2026, insider phonefuturist claimed Samsung and Google are jointly developing the new software, which is reportedly also called Galaxy OS internally.
  • According to the leak, the Google partnership includes paid features from third-party services alongside built-in AI tools.
  • If Samsung follows its One UI 9 schedule, a beta could arrive around May 2027 and a stable release around July 2027 with the Galaxy Z Fold 9 and Z Flip 9.
  • Based on Samsung’s update promises, One UI 10 would be the last major update for the Galaxy A15, A25, A35 and A55, while the Galaxy S23, S23 FE, Z Fold 5, Z Flip 5, A54, A34 and A24 are expected to stop at One UI 9.

A possible new name: Galaxy OS

The details surfaced on October 11. Insider phonefuturist said Samsung is working on the new software together with Google. According to the insider, the project is referred to internally both as One UI 10 and as Galaxy OS. If that name is adopted, it could replace the One UI branding that Samsung phones have carried since 2018.

The timing would be symbolic. The first One UI launched in late 2018, so the new version would coincide with the software’s tenth anniversary, and the source notes that Samsung usually prepares something big for milestones like this. Sammy Fans, which picked up the leak, argues that One UI has become convenient but overloaded over the years. It describes a complete ground-up redesign as something users have long wanted.

The main caveat applies throughout this article: Samsung has not officially said anything about One UI 10, and plans may change before release.

Some AI features may cost extra

According to the leak, the centerpiece of the new software is artificial intelligence integrated deeply into the system with Google. The insider says this partnership includes paid features from third-party services. That would create a two-tier arrangement: some AI capabilities would be built into the system, while others would be opened up to external services that may require a separate payment.

Galaxy owners have wondered for several years which Galaxy AI features will stay free and which will move behind a subscription, and Samsung’s answers to that question have varied. The current expectation is that core features will remain free, with paid partner services offered as optional extras. The source warns that if Samsung gets this balance wrong, One UI 10 may be remembered for something other than its new design.

Regional availability is another consideration. Part of Samsung’s AI feature set relies on Google’s Gemini. The more tightly the new software depends on Google, the greater the chance that some features will be unavailable in markets where Gemini or the relevant paid services do not officially operate.

A hint at the new interface: Samsung’s Fluid AI Design System

In 2026, Samsung won a Red Dot award for an interface concept called the Fluid AI Design System. In this concept, the screen is no longer a fixed set of static icons and windows. Instead, the system understands what the user is doing and changes the layout and appearance of elements accordingly.

The concept images have several notable features:

  • Apps and widgets look like frosted glass.
  • A floating round orb represents an AI assistant that carries out tasks for the user, such as finding a place on a map, locating a calendar entry, and working across several apps and devices at once.
  • When the orb approaches an interface element, that element appears to be pulled toward it or to bend.
  • When the assistant gathers data from apps, lines appear on screen to show where the information comes from.

Samsung has not confirmed that this concept will become part of One UI 10. Still, the direction is clear: an interface built around an AI assistant.

What else is expected beyond the design

There is no official changelog yet. However, SamMobile, which has covered Samsung for many years, lists the most likely new features:

  • more appearance customization, updated apps and new widgets;
  • AI assistants that complete tasks in the background;
  • a detailed log of what AI is doing on the phone, building on a dedicated section that already appeared in One UI 9;
  • improved DeX and Secure Folder;
  • more apps optimized for tablets and foldables;
  • tighter integration with other Samsung devices, including the Galaxy XR headset, smart glasses and the Galaxy Ring.

These are forecasts, not leaks. They follow logically from what Samsung has done over the past two years, since many One UI 9 features are also AI-related.

Likely based on Android 18

One UI 10 will most likely be built on Android 18. One UI 8 shipped with Android 16 and One UI 9 with Android 17, and each new full version of One UI has come with a new Android version.

Not to be confused with Android 10

Searches for “One UI Android 10” refer to something else entirely: Samsung phones received Android 10 back in 2019 with One UI 2. Similarly, support for the Galaxy Note 10 ended with One UI 4.1 on Android 12. One UI version numbers and Android version numbers have not matched for a long time.

How the update will arrive and how to install it

One UI 10 is expected to arrive the same way previous versions did: as an over-the-air update. To check whether an update is available:

  1. Open Settings.
  2. Go to Software update.
  3. Tap Download and install.
  4. If an update is found, tap Download. Once it has downloaded, tap Install now.

Before installing a major update, it is worth taking three steps:

  • Back up photos and contacts to the cloud or with Smart Switch.
  • Free up several gigabytes of storage.
  • Charge the phone to at least 50 percent.

Menu names may differ slightly depending on the model and firmware version.

Updates roll out in waves: South Korea comes first, followed by India, Europe and the US, and then other countries. Before the stable release, Samsung runs a beta program through the Samsung Members app, but the beta is open in only a few countries.

When One UI 10 could be released

There is no official release date. Samsung’s schedule has been very consistent, though, so it can be used to estimate timing. One UI 9 rolled out as follows:

  • May 2026: first beta on the Galaxy S26;
  • July 2026: stable version alongside the new Galaxy Z Fold 8 and Z Flip 8 foldables;
  • September 2026: update for the Galaxy S26;
  • October 2026: update for the S24, with the S23 and other models next in line.

If Samsung follows the same path, the timeline would look like this:

  • A One UI 10 beta would appear around May 2027.
  • The stable version would arrive around July 2027 with the Galaxy Z Fold 9 and Z Flip 9.
  • Flagships from previous years would begin updating from August to September.

Before that, an interim One UI 9.5 is expected in early 2027, debuting on the Galaxy S27. All of these dates are projections based on past behavior, not announcements.

There is no official eligibility list yet. However, Samsung commits in advance to a specific number of major Android updates for each model. Based on those commitments, One UI 10 should reach the following devices:

  • Galaxy S: S24, S24+, S24 Ultra, S24 FE, the entire S25 series including the Edge and FE, the S26 series, and the upcoming S27;
  • Foldables: Z Fold 6 and Z Flip 6; Z Fold 7, Z Flip 7 and Z Flip 7 FE; Z Fold 8 and Z Flip 8; and the TriFold;
  • Galaxy A: A16, A26, A36 and A56, which Samsung promises six Android updates, plus newer models in the series.

For four popular models, One UI 10 would be the last major update: the Galaxy A15, A25, A35 and A55 were promised four Android updates, and Android 18 would be the fourth.

The Galaxy S23 and S23 FE, Z Fold 5, Z Flip 5, A54, A34 and A24 are not expected to get One UI 10. Their last major version will be One UI 9. They will continue to receive security updates, but no new features.

For anyone planning to buy a Samsung phone soon who wants One UI 10 and the updates after it, the source advises choosing a model no older than the Galaxy S24 or A16.
