OxygenOS (Chinese: 氧OS; pinyin: yǎng OS) was an Android-based operating system (OS) developed by Chinese smartphone manufacturer OnePlus exclusively for their smartphones. OxygenOS was developed for their overseas market. There used to also be another version of the OS designed specifically for the Chinese market called HydrogenOS (Chinese: 氢OS; pinyin: qīng OS). On July 16, 2026, OnePlus announced that OxygenOS would shut down, along with the announcement that it would exit the North America and Europe markets.
History
In an interview published on 3 September 2016, XDA Developers revealed OnePlus was "actively merging both platforms (OxygenOS and HydrogenOS) into a single cohesive operating system based on Android".
In July 2021, OnePlus merged OxygenOS with Oppo's ColorOS. Both companies' software will remain separate and continue to serve their individual regions (OxygenOS for OnePlus phones globally, ColorOS on OnePlus and Oppo devices in China) but share a common codebase, which OnePlus says should standardize its software experience and streamline the development process for future OxygenOS updates.As of July 2026, Oppo said that existing OnePlus devices in the United States and Europe would transition from OnePlus's OxygenOS 16 to Oppo's ColorOS 17 for future software updates. The company said that software updates and after-sales support would continue, and also users will have the option to roll back to OxygenOS 16.
