Huawei has officially announced HarmonyOS, the operating system it was rumored to be developing to replace its reliance on Android. In China, the software will be known as Hongmeng. The company says the operating system, a microkernel-based distributed OS, can be used in everything from smartphones to smart speakers, wearables, and in-vehicle systems to create a shared ecosystem across devices. The operating system will be released as an open-source platform worldwide to encourage adoption.

There’s been a lot of speculation about Huawei’s in-house operating system ever since Google suspended the company’s Android license back in May, following the US government’s decision to put Huawei on the Entity List. Huawei has made no secret of the fact that it’s been working on its own OS, but the extent to which it would be able to act as a substitute for Android is unclear.

Huawei plans to launch HarmonyOS on “smart screen products” later this year, before expanding it to work on other devices, like wearables, over the next three years. The first of these products will be the Honor Smart Screen, which is due to be unveiled on Saturday. Huawei has yet to explicitly say what constitutes a “smart screen” device, but Reuterspreviously reported that the OS would appear on a range of Honor smart TVs. The focus for the operating system will be products for the Chinese market at first, before Huawei expands it to other markets.

In a statement, the CEO of Huawei’s consumer business group, Richard Yu, says that HarmonyOS is “completely different from Android and iOS” because of its ability to scale across different kinds of devices. “You can develop your apps once, then flexibly deploy them across a range of different devices,” the CEO says.
