Google recently launched the Pixel Watch 2 with Wear OS 4, while the original Pixel Watch remained on Wear OS 3.5. That changes today, with the company rolling out the Wear OS 4 update to its first in-house smartwatch. The incoming update brings a number of new features, safety upgrades, bug fixes, performance enhancements, and battery improvements. It will roll out to all compatible devices in phases “over the coming weeks.”
