China’s Huawei has applied to trademark its “Hongmeng” operating system (OS) in at least nine countries and Europe, data from a U.N. body shows, in a sign it may be deploying a back-up plan in key markets as U.S. sanctions threaten its business model.
If you need to make your own operating system in the current market, you’ve already lost. Huawei is in a very deep hole.
Surely just buy up an exisitng OS. Sailfish springs to mind. Few mil and they have a viable OS with an android run time. That’s without looking at KaiOS (firefoxOS) or other linux based phone systems
