Samsung has officially ended software support for its flagship Galaxy Watch 4 and Watch 4 Classic smartwatches. The company removed these devices from its Mobile Security work scope schedule, meaning they will no longer receive any software or security updates. This marks the conclusion of Samsung's commitment to provide four generations of Wear OS upgrades for these watches.
The August 2026 security patch will be the final update these devices receive. Samsung had previously promised to deliver the One UI 8 Watch update to the Galaxy Watch 4 series, but this will now be canceled. The removal from Samsung's security work scope schedule confirms that these watches have reached the end of their supported lifecycle.
The Galaxy Watch 4 and Watch 4 Classic launched in 2021 as Samsung's first wearables running Google's Wear OS platform. These devices represented a significant shift for Samsung, moving away from their proprietary Tizen operating system. Over their lifetime, they received several major software updates including transitions to Wear OS 3 and Wear OS 4. With the termination of security support, users face potential vulnerabilities as new threats emerge that won't be addressed through official patches.
Owners of the Galaxy Watch 4 series can expect their devices to stop receiving critical security protections starting with the August 2026 patch cycle. The cancellation of the One UI 8 Watch update means users miss out on promised new features and interface improvements. While the watches will continue to function for basic timekeeping and notification purposes, their long-term viability in an increasingly connected ecosystem is questionable. Many users may consider upgrading to newer models to maintain security and feature parity with their smartphones.
Will my Galaxy Watch 4 still work after security support ends? Yes, basic functionality including timekeeping and notifications will continue to operate, but you'll miss security patches.
Is there any way to extend support for these watches? Unfortunately, once Samsung removes devices from their security schedule, there are no official methods to restore updates.
Should I upgrade my Galaxy Watch 4 now? Consider upgrading if you rely on your watch for banking, payments, or sensitive apps that require regular security updates.
