I do use a Pinephone (not pro) for 5y now. I switched to the "stable" branch of pmos 2y ago which made my life siginicantly more hassle free. Note that pmos support for pinephone (not pro) degraded in recent stable release, so i recommend to not run 24.12 but the prior version. you will still get occasional updates from the stable alpine branch it's based on (which makes 99% of available packages anyway).

VoLTE works fine (phosh with gnome-calls)
