Watch4 Update Support Ends — Samsung Drops Security Patches

Samsung has pulled the plug on two of its most talked-about smartwatches. Quietly, and without fanfare, the Galaxy Watch4 and Watch4 Classic have been removed from Samsung’s security update roster — no new patches, no more OS upgrades.

Remember 2021? Samsung bet big and switched from Tizen to Wear OS with the Watch4 lineup. They launched in August of that year running Wear OS 4, later receiving an upgrade to Wear OS 6.0 topped by One UI Watch 8. That was the finish line for their Android software journey. The platform stop is complete: the watches will no longer even be listed for security maintenance in Samsung’s bulletins.

Why does that matter? Because a smartwatch isn’t just a shiny wrist accessory; it’s an extension of your phone and a holder of personal data. Security patches close holes. Without them, the device grows more exposed with time.

The closely related Galaxy Watch FE, released in 2024 as a refreshed 40mm Watch4, remains on the update list. It uses the same Exynos W920 processor and matches the Watch4’s memory and storage footprint, which explains the overlap in hardware lifespan. The Exynos W920 also powers the Watch5 series, and those devices will continue to receive support.

• Chipset: Exynos W920
• RAM: 1.5GB
• Storage: 16GB

If you own a Galaxy Watch4 or Watch4 Classic, they will no longer receive security updates.

For what it’s worth, the Watch4 generation had a solid support run — roughly five years from launch to its last update in August. That mirrors Samsung’s current commitment for newer devices; the Galaxy Watch9 and the Watch Ultra2 are also slated for five years of OS and security updates.

So where does that leave owners? You can keep wearing a Watch4, enjoy its features, and accept the growing security risk. Or you can treat this moment like a crossroads: evaluate newer models that still receive active support, or look at third-party options if longevity matters more than brand continuity. Either way, this marks the end of an era for Samsung’s first Wear OS watches — and a reminder that even durable hardware has an expiry date for software care.
