I really think sandboxing built-in emulator for android apps has to occur for the phone to get traction. I think i'm their ideal consumer and still can't see the value yet. I'm a technical person who is willing to deal with some issues/trade-offs for privacy, but still can't reach the tipping point to purchase.
I also think this a place where duckduckgo could partner with with their services. I think most consumers wants things to be polished and just work.
Fortunately in 2019, mobile devices aren't as reliant on native apps. I use Uber's PWA and Google Maps Go PWA, which used to be my biggest app-only dependencies. For other stuff, I find that the stock music and video player apps are more than good enough.
