The KeYue version is a variant of the Chinese smartphone operating system, derived from Android. It is primarily associated with the Chinese tech giant Huawei. The origin of the KeYue version can be traced back to Huawei's response to the restrictions imposed by the U.S. government on the use of Google's Android services in its smartphones.

Huawei, facing the ban on using Google Mobile Services (GMS) in its devices, developed its own ecosystem, which includes the KeYue OS. This operating system is designed to mimic the user experience of Android while providing Huawei's own suite of apps and services. According to a report by Counterpoint Research, Huawei's smartphone shipments in the United States decreased significantly after the imposition of the ban, which underscores the importance of the KeYue version in maintaining Huawei's market presence in the region. The development of the KeYue version was a strategic move to ensure that Huawei's devices could still offer a seamless user experience, despite the limitations imposed by the U.S. restrictions.
