One UI 9 Watch: Which Galaxy Watches Will Get the Wear OS 7 Update?

If you have used a Galaxy Watch for a few years, you probably know the feeling: a new software update arrives, you open the Galaxy Wearable app and the first thing you wonder is, “Will my watch get it too?”

That question is now back with One UI 9 Watch. Samsung has introduced its latest smartwatch software with the Galaxy Watch9 and Galaxy Watch Ultra2 and it is built on Google’s Wear OS 7. But as the update starts making its way beyond Samsung’s newest watches, things become a little less clear.

Samsung has not yet published a final, complete eligibility list for every older Galaxy Watch. That leaves many owners looking at their watches and wondering whether they are still part of Samsung’s update plan.

And that is where the One UI 9 rollout gets interesting. The answer depends not only on how old your Galaxy Watch is, but also on how Samsung is handling software support across different generations.

One UI 9 Watch Eligibility

Galaxy Watches That Already Have One UI 9 Watch

Galaxy Watch9

The Galaxy Watch9 comes factory-installed with One UI 9 Watch that runs on Wear OS 7. Since the operating system is built-in from the very beginning, there is no need to install the first platform upgrade. All core visual adjustments, modern interface elements and new health dashboard layouts work out of the box.

Galaxy Watch Ultra2

The Galaxy Watch Ultra2 is also a built-in installation platform for One UI 9 Watch and Wear OS 7. The hardware platform of this watch was built for outdoor and endurance use scenarios, so all the new optimizations were taken into account during its development. Just like the regular Galaxy Watch9, the Ultra2 operates on the new interface out of the box.

Galaxy Watch Expected to get the One UI 9 Watch Update

Owners of the previous generations have the opportunity to use One UI 9 Watch through updates of the official firmwares.

Galaxy Watch8 and Watch8 Classic

Galaxy Watch8 and Watch8 Classic are two of the highest-priority options on the update list that almost certainly should get the new version. Since they were released as the last generation before the current one, they are still far away from being discontinued.

Internal test builds and firmware testing of the Watch8 generation, including recently seen test firmware for Watch8 Classic, prove the preparation work of the software by Samsung. Though the exact dates of releasing the official stable firmware may differ for the carriers and regions, those two are likely going to be among the first to be updated to One UI 9 .

Galaxy Watch Ultra

Samsung has officially promised to bring One UI 9 Watch to the original Galaxy Watch Ultra. As a high-end device that uses the modern processor and has enough memory for running the Wear OS 7, it will definitely receive the new firmware.

Though certain sensor data of the ninth generation hardware is exclusive to the new devices, the basic operating system and all of the UI components will appear on the original Ultra along with other Galaxy watches.

Galaxy Watch7

Galaxy Watch7 is likely to get One UI 9 Watch since internal firmware testing has been found by users in community databases. The reason why this watch deserves its place in this list is due to the fact that there are some new features that can be implemented only using the hardware of the seventh generation.

Daily Cardio Load, for instance, is the feature that was officially announced by Samsung for Galaxy Watch7 and newer with One UI 9.

Galaxy Watch FE

Galaxy Watch FE is a special model compared to the rest in the lineup. Although it was released later than the sixth generation watches, the internal hardware of the device is similar to those seen in older architectural designs.

In spite of the similarities in hardware, the date of release guarantees that Galaxy Watch FE will fall within the four years of support for the software update cycle. Thus, it means that Watch FE is likely to receive One UI 9 Watch. However, it is worth noting that not all the computational metrics will be included in the FE edition due to the differences in hardware capabilities.

Galaxy Watch6 and Watch6 Classic

Galaxy Watch6 and Watch6 Classic are two devices in the lineup that have all chances to get the One UI 9 update. There is no doubt about the progress of development, since there have been spotted internal tests in Samsung’s servers.

Both the ordinary Watch6 and its rotating bezel alternative, called Watch6 Classic, can boast the hardware power to operate Wear OS 7. Although not all the health-specific features from the newest hardware will be inherited by this generation, the improved notification system and widgets are expected to be there.

Galaxy Watch5 and Watch5 Pro

Galaxy Watch5 and Watch5 Pro are probably the most interesting example in relation to the development of One UI 9 Watch. Released in 2022, these devices are going to reach their fourth year on the market in 2026, which marks the end of the four years OS support promise made by Samsung.

Recent findings of internal One UI 9 test firmware of Galaxy Watch5 family clearly indicate Samsung’s plans to introduce the Wear OS 7 to the family. This way, Watch5 and Watch5 Pro owners will receive a decent upgrade and be able to prolong the lifespan of their wearables.

Will Galaxy Watch4 and Watch4 Classic Get One UI 9 Watch?

The short answer for Galaxy Watch4 and Watch4 Classic owners is: probably not.

Galaxy Watch4 was introduced back in 2021 as the groundbreaking device which became Samsung’s legendary comeback to the Google Wear OS. The company’s official update policy provided up to 4 years of support with One UI Watch and Wear OS, which practically covered all 2022 to 2025 years as major releases years.

As far as we know, there isn’t any One UI 9 Watch test firmware for the fourth generation of Galaxy watches. Even though there isn’t any official announcement from Samsung stating that this fourth generation won’t get the update, all evidence points towards one UI 8 Watch forever.

What About Galaxy Watch3, Active2 and Older Watches?

The old generation smartwatches like Galaxy Watch3, Galaxy Watch Active2 and Galaxy Watch will never get the One UI 9 Watch version irrespective of any reason.

This is because these old generation smartwatches run on Tizen Operating System, the exclusive property of Samsung instead of Wear OS Platform of Google. The Wear OS 7 and One UI 9 Watch versions are developed solely based on the new architecture of Wear OS from Galaxy Watch4 onwards.

What’s New in One UI 9 Watch?

One UI 9 Watch is a two-layer update, where Google provides its Wear OS 7 operating system and Samsung adds its custom layer, One UI Watch.

Improvements in Wear OS 7

On the base level, Wear OS 7 introduces significant improvements to wearable performance, response and media control:

• Live Updates: Glancable cards show notifications from ongoing background activities such as turns or delivery of food.

• Wear Widgets: New interactive widgets deliver rich interactions within the home screen without launching full apps.

• Media Controls Enhancements: Volume controls, media playback routing and playlists browsing have better touch targets and visuals.

• Continuity Across Devices: Increased connection between compatible Android devices results in faster notification syncing.

• Increased Power Efficiency: The system-level battery efficiency gains around 10% improvement compared to Wear OS 6 according to Google, but the actual increase in the Galaxy Watch will be determined by user settings and display use.

• Enhanced Gemini Intelligence roadmap: Better integration with Google backend enables more context-aware processing of assistant models’ requests.

Samsung Health and Fitness Updates

Samsung adds a new layer visually by using its custom health algorithms and measurements:

• Vital Metrics: Consolidated morning metrics for monitoring sleep, heart rate and physiological metrics.

• Heart Health Rating: Visual indicator of the cardiovascular metrics collected during daily activities.

• Cardio Load: Unique metric for measuring exertion throughout the day for avoiding overtraining (available only for some devices).

• Fitness Index: New indicators for measuring baseline cardiovascular stamina and progress.

• Updated Design: Neat visual design, large font size and improved visual data representation throughout Samsung Health app.

Gemini and Smarter Watch Integration

In One UI 9 Watch, Google’s Gemini engine is integrated even deeper into the user’s workflow. Users can use natural language commands for writing responses, scheduling appointments and controlling the smart home devices.

It should be noted that Gemini voice assistant functionality differs from Google’s Gemini Intelligence functionality.

Not Every Galaxy Watch Will Get Every One UI 9 Feature

Having access to the One UI 9 Watch does not necessarily make the older smartwatch behave similarly to a completely new flagship. This list of features is subdivided into the following three functional categories:

1. OS-Based Features

These are the features that can be accessed through nearly all watches with the latest OS updates. They include newly designed notification cards, revised quick settings panels, redesigned system fonts, media player modifications and general improvements to the OS based on Wear OS 7.

2. Limited to Specific Generations of Watches

Sometimes Samsung intentionally limits the application of algorithmic features to more recent generations to provide better processing performance. An example of such a limited feature would be the Daily Cardio Load that is only available on Galaxy Watch7 and later watches equipped with the latest OS.

3. Limited by Hardware Capabilities

There are features that are only available due to the presence of certain hardware sensors, processors or display technology. New sensors for health tracking, water resistance, GPS accuracy and physical buttons are available only on watches like Galaxy Watch9 and Galaxy Watch Ultra2.

Is One UI 9 Watch the Same as Wear OS 7?

Though they are often mentioned side-by-side, both terms are related to different components of the software ecosystem.

Wear OS 7 is an operating system provided by Google that deals with core engine, memory management, background services, Bluetooth functionality and Google Play Store architecture.

One UI 9 Watch is Samsung’s own interface and feature overlay running on top of Wear OS 7. It is made up of Samsung’s unique design, watch faces, Samsung Health support, quick panels designs and ecosystem-specific apps such as SmartThings and Samsung Wallet.

To better understand the difference between the two systems, it is useful to imagine Wear OS 7 as an engine and chassis of the car, whereas One UI 9 Watch is its dashboard and interior design.

How to Check for the One UI 9 Watch Update

After Samsung releases stable builds to the market, you can check for any new updates via the software menu as follows:

• Open the Galaxy Wearable application from your Android smartphone that is paired with your watch.
• Go to Watch settings.
• Scroll to and tap Watch software update.
• Tap Download and install.

An update will start downloading automatically if there is any available for your model, carrier and region. Ensure your watch is above 30% charged and stays connected to the charger while installing the update.

Wrap Up

One UI 9 Watch is more than just another software update. In addition to a new operating system and smart health features, the update comes with better UI and enhanced integration of the Gemini platform on Samsung Galaxy Watches.

Things get slightly more complicated when we talk about the watches which aren’t among the newest. The Galaxy Watch5 and the newer models seem to be in quite a favorable position for getting the update, but the Galaxy Watch4 owners may be at their last legs. And even if some older watches get One UI 9 Watch, they won’t necessarily get all the features from the latest devices.

Therefore, if you’re sitting there trying to guess whether there will be an important update for your Galaxy Watch, it might be the best decision to wait for the Samsung announcement first.
