OxygenOS (Chinese: 氧OS; pinyin: yǎng OS) is a customized version of the Android mobile operating system developed by Chinese smartphone manufacturer OnePlus exclusively for their smartphones. OxygenOS was developed for their overseas market. There is also another version of the OS designed specifically for the Chinese home market called HydrogenOS (Chinese: 氢OS; pinyin: qīng OS).
In an interview published 3 September 2016, XDA Developers revealed OnePlus was "actively merging both platforms (OxygenOS and HydrogenOS) into a single cohesive operating system".
Notable features of version 2.0 and 2.1.1 include app permissions, Waves MaxxAudio, SwiftKey keyboard, off-screen gestures, custom icons, dark mode, manual camera mode, and RAW support for 3rd party apps, like Camera FV-5 2.75.
On 10 October 2017, a security researcher discovered that an OxygenOS system service named "DeviceManagerService" collects sensitive data and sends it back to OnePlus servers. The service collects many data points, including the device serial number, phone number, IMEI, network connections, and timestamped records of user activity within every app. Users can uninstall the system service via ADB. Later, OnePlus released a statement about data collection and analytics, claiming that the data are only used for system improvement and optimization, are not shared with third parties, and can be disabled by users in the system settings. OnePlus also says that they are revising the data analysis mechanism, and will no longer collect certain data.
In 2014 OnePlus promised a "close to stock, bloat-free and highly customizable" experience. They soon held a "Name the ROM" contest in search for a name. On 30 January 2015 OnePlus officially announced the names OxygenOS and HydrogenOS. The winner of that contest, @Midifire from Belgium, was flown out to their headquarters in Shenzhen, where he got to meet the team, along with their CEO, Pete Lau.
