As a platform, the HarmonyOS 2.0 beta - complete with smartphone support - was made available in December 2020, with the company promising that a full release of the new operating system would arrive on its smartphones sometime in 2021.
While no specific date was mentioned during this latest announcement, Yu proclaimed that “Huawei flagship phone users will be able to upgrade their phones to HarmonyOS starting from this April,” going on to confirm that the newly-launched Mate X2 would be the first phone to support the operating system, when it releases.
Currently, the Mate X2 is cited as running EMUI 11 running atop Android 10 on Huawei's website, but while the company has billed HarmonyOS as its own platform, a deep-dive into the Harmony OS 2.0 beta and its development tools, conducted by Ars Technica in early February, revealed that despite the marketing speak, HarmonyOS was essentially open-source Android 10 with some liberal rebranding.
Early testing has suggested that there's little difference, beyond the substitution of the Android name with HarmonyOS' - at least in the platform's current guise - and that differentiating features won't likely manifest until future releases roll out.
Huawei has gone on record to say that it hopes some 200 million devices will be running on HarmonyOS 2.0 before the year's end. We're just left wondering how many of those will be available outside of China and what benefits the move from Android to HarmonyOS presents considering the current state of the platform.
