OnePlus, a Chinese Android phone brand announced in early this year that has drawn much attention in China and overseas, is building a team to develop a customized Android system, just like many other Chinese Android phone makers such as Xiaomi do. The in-house developed system will be loaded in the future models by the company sold in the mainland China. Its first flagship model OnePlus One, launched in April, came with Color OS, the custom Android system developed by OPPO (where OnePlus team were from) for mainland China users, and CyanogenMod (CM), an open source Android-based system, for overseas consumers. Xiaomi, one of the fastest-growing Android phone brands in China, made it clear from early on that Android phone and other hardware products would be only one of its businesses. Most brand Android phone makers in China would develop a customized system for their products.
