It might not be Ubuntu related but I figured a bunch of you will be interested in knowing that a second PinePhone Community Edition will go on sale shortly, this one pre-loaded with postmarketOS.
This video showcases 4 different Linux operating systems, including LuneOS and Ubuntu Touch, running on the PinePhone Brave Heart edition.
This video shows Mozilla Firefox, GIMP and a Qt5 Matrix client running on a PinePhone with postmarketOS installed. Are they usable? Find out.
