Wear OS & Pixel — Wear OS 3 was developed in collaboration with Samsung and Google, pulling in a little bit of Tizen, Samsung’s custom operating system, along with Google’s pre-existing work with Wear OS. Until now, Samsung’s take on Wear OS for the Galaxy Watch series has prioritized the company’s ecosystem, but with Google’s own Pixel Watch launching later this fall, it seems like Google services are going to start trickling back into the larger Wear OS ecosystem overall.
