OnePlus 9 Series Runs on Oppo’s ColorOS in China

According to the latest news, for its new OnePlus 9 series in China, the OnePlus is switching to ColorOS. ColorOS is an operating system that is used by Oppo smartphones. This was first announced on OnePlus’ forums by Gary C, the product lead on OxygenOS. Note that OnePlus phones run on OxygenOS in the rest of the world.

Gary C said “As a global technology company, we always look for ways to address the different usage habits and preferences among our users worldwide. We truly believe this customized new operating system will bring our Chinese users a software experience that is better suited to their liking.”


Note that this does not change anything for the global OnePlus 9 series that is set to be unveiled tomorrow. It will run in OxygenOS. HydrogenOS is the China-specific version of Android that OnePlus uses on all of its phones. In China, ColorOS is more widely used and popular than HydrogenOS.

Recently, Oppo became the biggest smartphone brand in China. Both Oppo and OnePlus are owned by Chinese conglomerate BBK Electronics. Another BBK brand, Realme also used ColorOS before launching its own operating system, Realme UI. In general, all these companies tend to publicly downplay the connection between themselves. However, OnePlus deciding to use Oppo’s software is a clearly visible example of collaboration.
