>Banking, Neobrokers, Public Transport in many German cities (costs are higher without using Android),

Dang, that sounds... frustrating. I guess I just kind of assumed the US would be the hardest place to de-google, but, apparently, I stand corrected. Apologies.

Canada sounds best, but here in the US, there's just a few inconveniences holding back my libre phone (other than the slowness, lack of water resistance, and mild tendency to overheat).

The one I'm most stumped on (currently, now that proton has a very nice Auth app!!) is routing with traffic via something like Organic Maps. There are some hacks floating around, but certainly nothing that meets the spare-time implementable (even for this introvert nerd...) plus reliable.

And the fact that, by the time I have it working, I'll probably finally be upgrading to a car with CarPlay or Android Auto or whatever it is.
