My primary for the time being remains GrapheneOS, which, ironically enough, only runs on Pixel hardware for now (though the GOS team is working with an unnamed major Android OEM to produce a handset that meets GOS's strict platform requirements).

My Linux phone is a PinePhone pro, which I believe is no longer being sold. It's not great. Phosh could generously be described as "in progress" last time I used it. UIs for many applications aren't built for small touchscreens like that.

I'd have to review the hardware market again if I were going to make a fresh recommendation. Librem looks cool conceptually, but they're a bit pricey, and their framing of a "Made in USA" variant as a premium feature rather than a red flag, a reputation risk, and a supply chain risk make me skeptical of whether Librem is a trustworthy entity at all, or might just be controlled opposition. That could just be me erring on the side of paranoia, though.
