If you have a newer Wear OS watch, sometime in the coming month, you’ll get a software update that will change what happens when you swipe on your watchface. Alongside the new UI, Google is also adding a new feed of information from Google Assistant, faster access to Google Fit, and a more information-dense view of your notifications.
It’s a much-needed cleanup and refinement for the big changes that came in Wear OS 2.0 (née Android Wear). That update changed a bunch of stuff to make it easier to get to apps and switch watchfaces, but it also felt like a significant step backward when it came to reading notifications. Currently, you can swipe left or right to change watchfaces. But when the new update hits, those gestures will map to something new, and you’ll need to long press to change faces.
