In 2021, Samsung introduced the Galaxy Watch 4 and Galaxy Watch 4 Classic, marking a major change for the company. These were the first Samsung smartwatches to use Wear OS, a platform developed by Google. Previously, Samsung had used its own operating system called Tizen. This shift was a significant step in Samsung’s strategy to align more closely with Android-based ecosystems. Recently, Samsung has announced that it will no longer provide security updates for the Galaxy Watch 4 and Galaxy Watch 4 Classic. This change was noted by tech news site Android Police after the release of Samsung’s September 2026 update bulletin. The last update these watches received was in August 2026. While the watches will continue to perform basic functions like telling time, tracking health, and running existing apps, they will no longer receive new features or software improvements. The Galaxy Watch 4 was a milestone for Samsung. It was the first model to transition from Tizen to Wear OS, a platform Samsung co-developed with Google. In 2022, Samsung promised to provide four generations of software updates for these watches, including updates to Wear OS and One UI Watch, its custom user interface. Samsung fulfilled this promise, taking the Watch 4 through multiple software versions, from Wear OS 3.5 to Wear OS 6, along with One UI 8 Watch, which was released at the end of 2025. Samsung has since raised the standard for its newer models, such as the Galaxy Watch 9 and Galaxy Watch Ultra 2, launched this summer. These newer watches are eligible for five major software updates and five years of security patches. Meanwhile, older models like the Galaxy Watch 4 remain on the previous four-generation update policy, though they still receive five years of security patches. While the Galaxy Watch 4 won’t get future updates, it still operates with One UI 8 Watch and all its current features, which remain functional for users.
