The United States of America declared Huawei off-limits to US firms working with them. That ban makes it impossible for Google to furnish Huawei with the latest version of Android which, in turn, makes Huawei phones vulnerable to future security threats. Huawei indicated some time ago that theyd develop their own operating system as a way around the problem. Its called HarmonyOS and may have been ready to ship for some time. The OS is only available in Asia, but the software isnt yet available in your territory.”]
