Samsung has quietly closed the update chapter on two of its most important smartwatches. The Galaxy Watch 4 and Galaxy Watch 4 Classic, the devices that first brought Samsung into the Wear OS era back in 2021, are no longer receiving any software updates, including security patches. The confirmation came through Samsung’s own security update scope page, which was refreshed alongside the rollout of the September 2026 security patch for other Galaxy devices.
Once the page updated, it was clear the Watch 4 and Watch 4 Classic had been quietly dropped from the support list. Their final software release was the August 2026 security update, meaning there will be no further patches, bug fixes, or feature updates going forward.
This makes the Watch 4 series the very first Wear OS-based Galaxy watches to reach official end-of-life. It’s a milestone moment, marking the end of support for the models that redefined Samsung’s wearable strategy when the company ditched Tizen for Google’s Wear OS platform.
Launched in mid-2021 running Wear OS 3 with One UI Watch on top, the Galaxy Watch 4 and Watch 4 Classic went on to receive four major platform upgrades over their lifetime, moving through Wear OS 3.5, Wear OS 4, Wear OS 5, and finally Wear OS 6. That’s a respectable five years of combined feature and security support for a first-generation product, especially one that helped establish Samsung’s modern smartwatch software identity.
If your daily wearable is a Watch 4 or Watch 4 Classic, this is the moment to start thinking about a replacement, especially from a security standpoint, since no future patches means any newly discovered vulnerabilities will go unaddressed. Samsung’s current lineup, including the Galaxy Watch 9 and Galaxy Watch Ultra 2, ships with the latest Wear OS 7-based One UI Watch 9 software and years of update runway ahead.
The end of updates for the Galaxy Watch 4 and Watch 4 Classic closes out a landmark chapter for Samsung’s smartwatch lineup. If you’re still wearing one, it’ll keep working fine day-to-day, but for anyone who values ongoing security coverage and the newest Galaxy AI-powered health features, upgrading to a current-generation model is now worth serious consideration.
