OnePlus CEO Pete Lau recently confirmed in an interview that the company is working with Google to improve the Wear OS platform. Lau also said that OnePlus is working on a smartwatch, although he didn't say whether the wearable will run on Wear OS or not. Google is said to be on board to work on the Wear OS software as well as how the operating system interacts with Android phones and Android TV. Lau didn't address the fitness features that Wear OS needs to improve on. But with Google's pending acquisition of Fitbit, we expect to see developments in the health and fitness space.
It won't be the first time Google is working with an OEM to develop its software. Google has done so in the past with NVIDIA. The companies collaborated to make substantial changes to the Android TV Oreo update before updating NVIDIA's Shield TV series.
