I had a pinephone pro that I got to pretty good working state on postmarketos. The phone was still a bit under powered but after lots of tinkering it could do most everything I wanted it to. Battery life was the biggest issue, I could get about 5 hours max out of it. It would also get a bit hot at times which while not a huge problem was annoying. Problem is I dropped it on a run and broke it right before they announced they are discontinuing it. So I'm trying to find a new one, but the options don't look super great. If you are willing to use an old downstream (android) kernel, then there are quite a few options, of which i like the FLX1 best. But that makes running some up to data apps harder. I'm having a hard time finding good options mainline options though. The pinephone is too underpowered for daily use. The latest shiftphone and fairphone seem promising but full mainline support still isn't quite there and they pretty pricey too compared to the ppp.
