It has a microkernel architecture design in kernel mode with a single framework: the operating system derives from HarmonyOS NEXT, based on both OpenHarmony and Oniro OS operating system family that is the user mode of HarmonyOS NEXT system that takes full L0-L2 source code derived from LiteOS roots that selects suitable kernels from the kernel abstraction layer.^[4] The operating system was officially launched by Huawei in August 2019.^[5]
