Google is rolling out a September 2026 Wear OS update to Pixel Watch 2, 3, and 4 devices, introducing Gemini Personalization that uses offline profiles and online data from Gmail, Calendar, and other Google apps. The update adds new gesture controls like double pinch and wrist turn navigation for Pixel Watch 3 and newer models, plus improved voice activation on Pixel Watch 4 and later.
Samsung ended support for the Galaxy Watch 4 and Galaxy Watch 4 Classic after delivering four promised generations of Wear OS updates, with the devices excluded from Samsung's September 2026 security bulletin. The company has since released newer models including the Galaxy Watch 8, Galaxy Watch 9, and Galaxy Watch Ultra 2.
