ColorOS
ColorOS is a user interface created by Oppo based on Android. Initially, Realme phones used ColorOS until it was replaced by Realme UI in 2020. Realme UI uses some of ColorOS's apps. Starting from the OnePlus 9 series, OnePlus will preinstall ColorOS on all smartphones that are sold in mainland China instead of HydrogenOS (Chinese version of OxygenOS). In September 2026, Oppo announced that ColorOS has 770 million active users worldwide, spanning more than 90 countries and regions.
