The Pinephone is a cool "straight linux on a phone" project, but the mobile OSes available for it are all pretty buggy as of me writing this (October 2021).
I think the UI I've settled on is phosh, but I think it's missing some things.
Things I need to do
Working on it Working out how to compile new phosh builds
Waiting Tilting the phone upside down shold lock rotation on the long side
Waiting An open SSH session should stop the phone from going to sleep
