Meanwhile, many consumers of Huawei devices asked us, whether Huawei is planning to launch HarmonyOS 3.0 for the global Huawei smartphone owners? To answer that, we should look at some facts that have appeared previously on the ground.

Meanwhile, Huawei consumers are taking on EMUI 12 as their prime operating system and receiving it via OTA software update. Looking at the fact that HarmonyOS 2.0 is not coming to the global market, Huawei has made some changes in the core EMUI user interface and brought it much closer to its Chinese counterpart.
