I've been using phosh 0.21.0-3 and phoc 0.21.1-1 since danctnix released them on 15th September. Never had a crash (that I'm aware of). I never had a crash with v 0.20 either. 0.21 is much smoother for me in use. Since that time (and a megi kernel update) battery life if much better.
I do get occasional problems with audio calls though and that is because audio output gets set to "dummy". I have no explanation for this. We all signed up for these "quirks", right?
I find a more or less daily reboot keeps things working more smoothly.
