Overview
- Samsung expanded the May 2026 firmware—first released in South Korea—to Europe, South Asia and the United States in mid‑June, bringing the update to Galaxy Watch 7, Watch 8 and the Watch Ultra.
- The update is small at about 200MB and is security focused, with SamMobile reporting fixes for 36 distinct vulnerabilities in the One UI/Wear OS bundle.
- Firmware builds rolling out include L330XXS2AZE1 and L310XXS2BZE1 and the update appears available for both Bluetooth and LTE variants of the Watch 7, Watch 8 and the Ultra.
- The package adds no new user features or changes to health tracking and does not clearly resolve the March‑reported battery drain that testing and user reports tied to Google Play Services had flagged.
- Users should install the patch for security reasons and can check for it in the Wearable app or on the watch under Watch settings > Watch software update > Download and install.
