Huawei has taken this step to protect its market as losing access to Android would most likely cripple the company as it is totally reliant on Android for all its devices, until now. This crucial step will assure customers that Huawei is prepared for this eventuality. Further, HarmonyOS could potentially become a significant rival to Android.
US-China tensions are still a big factor on the hardware side with the restrictions selling crucial smartphone chips to Huawei in place. Such restrictions are forcing Huawei to become more like Apple and bring its capabilities in-house, especially those that are reliant on US technology. Before US-restrictions it was projected that Huawei would become the top smartphone manufacturer at the end of this year or early next year. However, with key advances in its capabilities, the road to top smartphone manufacturer for Huawei is still a possinbility, albeit delayed a year or two.
