Another FYI: Ubuntu Touch does not support VoLTE at all, thus it might be more difficult to use it in some networks and countries (for example, USA shut down 3G some years ago)
However, I was pleasantly surprised by the responsive UI, the browser, and Cinny (the Matrix Client)
This is fantastic news, and I wish them all the best. Reliable VoLTE/WoWiFi calls was my main (but obviously major) issue with the PinePhone.
