Huawei announced its Android replacement HarmonyOS with much fanfare and confidence last month. The company boasted it's on-par with Google's OS, if not better. Still, as a brand new OS, it has to solve the problem that defeated Windows Phone: app availability. This is why HarmonyOS can run ported Android apps through Huawei's so-called ARK Compiler, a program allowing developers to easily convert existing applications. Apparently, this software is far from ready, and many Chinese firms testing it report it can't even compile its own demo app properly at the moment.
