Too much fragmentation in OS ecosystem instead of making a unified front. Is Xiaomi planking to make all the apps themselves for their phones and electronic goods. Lol
HyperOS is still "android". Only Harmony Next is expected to decouple from android. I think its still built on top or linux or at least posix compatible but will be able run android apps in a container. The top 100 chinese apps are being herded to convert their apps. Also China has a few super-apps with mini-app eco system which will make the conversion easier.
