I have the AL00 too and I selected it intentionally. I travel a lot and it is the best model as far as world LTE compatibility goes. I'm going to tavel to India this summer and I'm looking forward to test it there with local sims, including VoLTE. Otherwise I'm from the EU and I don't regret my decision regarding chinese model.
You can turn your phone to English base by changing the language, time zone, adding bunch of Google aps including Gboard and use this keyboard. Then uninstall any unwanted chinese app or disable it completely if can't be unistalled.
Enable GPlay and replace or add desireble apps. You can even replace launcher with Nova for example, but I use emui now again, it is not so clumsy any more with Nugat and it adds some functionallities.
Not to mention other advantages of chinese model (voice recording..).
I wouldn't advise you to replace system with other, it is not safe because of different kernels and you can brick your phone easily. And besides you gain nothing.
First,i am also a FRD-AL00's user,i wish i can help solve your facing problem sincerely
