Samsung Galaxy Watch 4 will not get the One UI 9 Watch update

Samsung has officially released the latest version of its wearable operating system, One UI 9 Watch. While the vast majority of the company's modern smartwatch lineup is scheduled to receive the upgrade, older devices are officially reaching the end of their software support lifecycle.

• Samsung launched the Galaxy Watch 9 and Watch Ultra 2 in August featuring pre-installed One UI 9 Watch.
• The only models missing out on the new OS update are the Galaxy Watch 4 and Galaxy Watch 4 Classic series.
• Newer wearables starting from the Galaxy Watch 5 and up will receive the update by the end of 2026.
• The discontinuation of updates for older models marks the completion of their guaranteed four major OS upgrades.

The End of an Era for Galaxy Watch 4

Released back in 2021, the Samsung Galaxy Watch 4 lineup has exhausted its quota of major operating system upgrades. Having received four substantial updates including One UI Watch 4.5, One UI 5 Watch, One UI 6 Watch, and finally One UI 8 Watch, these devices have reached their natural software plateau. This applies to all variants, including special editions like the Galaxy Watch 4 Golf Edition and the luxury Galaxy Watch 4 Classic Thom Browne Edition.

This phase-out marks a significant milestone, as the Galaxy Watch 4 originally introduced Samsung's transition from the proprietary Tizen OS to Google's Wear OS platform. Over the years, these devices have proven remarkably reliable, serving as a cornerstone for Android-compatible smartwatches in the tech market.

What This Means for Legacy Device Owners

The absence of the One UI 9 Watch update means that owners of the Galaxy Watch 4 and Watch 4 Classic will no longer receive bug fixes, security patches, or new feature rollouts. Furthermore, future app compatibility may become a challenge as third-party developers adopt newer API requirements. Performance itself will not degrade immediately, but the lack of updates requires attention.

Fortunately, users have alternative options rather than discarding their old watches. A legacy Galaxy Watch can be repurposed into a dedicated sleep tracking device, a smart home control dashboard, a media remote, or handed down to someone needing basic notification tracking.

Future Updates and Hardware Upgrades

The new One UI 9 Watch brings a refined visual interface, wrist-raise AI assistant activation, and advanced health metrics like Daily Cardio Load and Heart Health Score. Samsung has extended software support for newer models like the Galaxy Watch 9 up to five major OS upgrades, making them fantastic long-term investments.

If you are still running a Galaxy Watch 4 series device, transitioning to a newer model like the Watch 9 or Watch 8 Classic provides better hardware performance, enhanced tracking sensors, and long-term security assurance compared to rival products on the market like the Pixel Watch 5.
