OxygenOS (Chinese: 氧OS; pinyin: yǎng OS) - OS on base Android, developed by a Chinese smartphone manufacturer OnePlus exclusively for their smartphones. OxygenOS was developed for the global marketplace. There is also another version of the OS developed specifically for the China market called HydrogenOS.

Privacy issues
On 10 October 2017, a security researcher discovered that OxygenOS system service called "DeviceManagerService" collects sensitive data and transmits it back to OnePlus servers. The service collects many data points, including the serial number of the device, the phone number, IMEI, network connections and time records of user activity in each application. Users can delete the system service through ADB. OnePlus later released a statement on data collection and analytics, arguing that the data is only used to improve and optimize the system, is not shared with third parties and can be disabled by users in system settings. OnePlus also says they are reviewing the data analysis mechanism and no longer collecting certain data.
History
In 2014, OnePlus promised the experience is "close to pure Android, without bloation and with great customization capabilities." Soon they held a contest "Name the firmware" in search of a name. On 30 January 2015, OnePlus officially announced the names OxygenOS and HydrogenOS. The winner of this @Midifire from Belgium was taken to the headquarters in Shenzhen, where he met with the team with their general manager Pete Lau.
