American restrictions cut Huawei off from Google’s Android mobile operating system, which destroyed Huawei’s smartphone business outside of China. In 2019, Huawei launched its own operating system called HarmonyOS, in a bid to replace Android. The company has been developing new versions of the system ever since, with an eye to regaining some market share in smartphones. Huawei has announced the latest version of its mobile operating system HarmonyOS 4 and an enhanced AI assistant, as the embattled giant ramps up efforts to re-establish strength for its smartphone business. Will the new operating system be able to compete with android outside China ?
