Correct me if I'm wrong, but I suppose emulating Android apps on a non-Android system will have the same problem as trying to run them in an Android without Google Services or in a rooted phone, i.e., banking (and similar) apps detecting it and refusing to run?

Were it not for that, I would never have stopped using Huawei, IMO the best phone brand by a mile. But I'm too busy a person to depend on hacks and having to regularly find new workarounds to access my banks.

I think you're right about certain apps refusing to run in an emulated environment.

I'm beginning to think we need to consider such apps, and the hardware they run on, as the outsiders. Keep a cheap "normal" Android phone for those apps, and those apps alone. Then keep a "real" second device for everything else. Up to you which one gets the SIM card and provides connectivity for the other (and ordinary phone services).

I'd rather go back to old-fashioned hardware dongles from banks – but hey, lacking that, maybe I'll just think of the first of those two devices as a clunky, overly expensive one of those.
