HarmonyOS is an operating system developed by Huawei, which does not belong to the Android system, but is a brand-new, independent operating system from Android. The HarmonyOS system is designed to provide a seamless experience across multiple devices, including smartphones, tablets, smartwatches, smart home devices, and more.
The HarmonyOS system is designed to provide a unified, distributed operating environment that enables different devices to work more closely together and achieve seamless sharing of data and services. It adopts a microkernel design, emphasizes security and low latency, and supports a rich application ecosystem.
Although the HarmonyOS system is independent of Android, Huawei has enabled the HarmonyOS system to support Android applications in order to ensure the compatibility and richness of the application ecosystem. This means that on HarmonyOS, users can still use many of their favorite Android apps while enjoying the new features and improvements that come with HarmonyOS.
Overall, the HarmonyOS is not Android, but it has put a lot of effort into compatibility to ensure that users are able to continue using existing Android apps during the transition period while exploring the new possibilities of the HarmonyOS system itself.
