Huawei’s HarmonyOS is making waves in the tech world, with the open-source version now deployed on over 1.2 billion devices globally. This achievement marks a new phase in the operating system’s rapid growth, cementing its position as one of the fastest-growing OS platforms ever.
The recent data, shared by China’s Ministry of Industry and Information Technology, highlights the extraordinary expansion of the HarmonyOS ecosystem, particularly within the industrial technology sector. As of January 2026, HarmonyOS has not only surpassed the impressive 1.2 billion device milestone but has also entered a new stage of widespread development.
A Rapid Rise for HarmonyOS
Launched by Huawei in 2019 for its own devices, HarmonyOS quickly transformed from a proprietary OS to an open-source platform. By releasing the source code under the OpenAtom Foundation, Huawei made it possible for developers worldwide to tap into the potential of HarmonyOS, leading to its adoption across various industries and platforms.
By June 2025, HarmonyOS was running on more than 1,200 product categories, spanning consumer electronics, industrial equipment, smart home devices, and enterprise technologies. Its open-source model has attracted over 10 million developers, making it one of the most rapidly adopted operating systems globally.
Why the Fast Growth?
Several factors contribute to HarmonyOS’s exceptional expansion. The key driver is the large-scale application across diverse industries, providing developers with ample opportunities to create and deploy applications. This broad adoption not only strengthens the software’s security and stability but also plays a crucial role in enhancing the reliability of industrial and supply chain operations.
Additionally, Huawei’s in-house programming language, Cangjie, is gaining momentum within the tech industry, further fueling the growth of the HarmonyOS ecosystem.
HarmonyOS 6 and Its Growing User Base
Recently, Huawei rolled out the HarmonyOS 6 update for consumer devices, supporting over 90 models through OTA (over-the-air) updates. The cumulative installation figures for HarmonyOS 5 and 6 have already reached 36 million devices, with more expected as Huawei continues to expand its user base.
Huawei’s ecosystem continues to evolve, with HarmonyOS driving the company’s growth and making it a formidable player in the global software landscape.
Huawei’s HarmonyOS has successfully scaled to 1.2 billion devices, solidifying its place as one of the fastest-growing operating systems in history. The platform’s rapid adoption across industries and its innovative ecosystem show that Huawei is not just participating in the tech revolution but actively leading it. With HarmonyOS continuing to gain ground, it’s clear that Huawei is reshaping the future of the software world.
