Huawei has finally announced that HarmonyOS, its Android competitor, will launch on June 2. The new operating system has been in development since 2019 and will run on the Huawei Watch 3 and other new Huawei-branded devices as they release. Not much is known about the operating system’s features or overall design, but Android Authority reports rumors that it will offer longer battery life, eSim support, and all-day body-temperature monitoring. Development began on HarmonyOS following the US ban on the China-based tech company in 2019. Following that ban, big companies began to pull support for Huawei, ultimately leading to Google even pulling Huawei’s Android license, forcing it to use the open-source version that modders use to create custom ROMs (essentially operating systems that users can download and install to their Android phones). Now, after a few years of development, we’ll finally get our first look at the new operating system, which will act as a competitor for Android in markets where Huawei operates. There have been a few leaks that show pictures of what the OS looks like, but no definitive announcements have come from the manufacturer, itself. The operating system will act as a complete replacement on all of Huawei’s smart devices and will launch with a special event on June 2 at 5 a.m. PT. At the moment, it is unclear if this will be a global or China-only launch.
