HarmonyOS 5

HarmonyOS 5 (also known as HarmonyOS NEXT) is a proprietary distributed operating system developed by Huawei that succeeded the similarly named HarmonyOS, with the main difference being that the "NEXT" operating system supports only HarmonyOS native apps. Unlike Android-based HarmonyOS versions 1 to 4 (2019–2024) and the global EMUI operating system, the Next version (first launched on the Pura X) does not include the Android AOSP core and is incompatible with Android applications. HarmonyOS NEXT both discards the common Unix-like Linux kernel and replaces the previous multiple-kernels system with its own bespoke HarmonyOS microkernel. The rich execution environment (REE) version of the HongMeng Kernel is placed at its core. The OpenHarmony-based operating system shares lineage with the lightweight LiteOS real-time operating system for resource-constrained devices like smart wearables and IoT products.
