We reported back in August that Wear OS was getting a hefty update from Google, and the new code is apparently now rolling out to compatible smartwatches. You might want to check the update screen on your wearable and see if the software is ready to go.

A lot of the new changes are cosmetic ones, with an improved, cleaner interface for notifications, the Google Assistant, and the newly revamped Google Fit. Wear OS should be easier to get around with the 2.1 update as well – you can use swipes from the main watch face to get to all the features that matter.
