Oxygen - Operating System

OxygenOS is an Android-based OS 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 market called HydrogenOS

Besides user-interface, OxygenOS also has several hidden features that could increase your productivity. If you’re a OnePlus user, these OxygenOS features could prove highly beneficial to you


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.
