How's the experience? I tried it on fp4 1-2 years ago, and it was pretty unstable for daily driving at the time. I returned to android for a while, and now I'm running PostmarketOS on this. It works reasonably well, but phone call audio doesn't work yet (speakers altogether started working just earlier this year) and that's kind of a dealbreaker. The development is also slow, as all the work is done by a single person (huge kudos to Luca Weiss).

So I'm thinking to maybe give Ubuntu Touch a shot. Tell me your experiences with it on a fp4.

Bonus question: wireguard is pretty important to my day-to-day life. Is it yet working? I remember that it was broken, couldn't install it due to something about drivers... There were workarounds, none of them worked on a fp4.
