I just ordered a pinephone, haven’t received it yet. The pinephone is the best native option in the U.S right now but you can get some unlocked smartphones with better hardware and install Linux it’s just a bit of a headache.

The general consensus is that it’s pretty low power, being one of the only chipsets that has publicly available design docs for it. It’s a mid tier 2015 era chipset. It a bit slow but works as a phone. You can probably emulate android apps in it.
