Thanks @C0n57an71n. This is the first time I'm using this site. No worries about non-availability of any fix for these issues I am reporting. The intention is to get them on the radar - I bought the Pinephone with the expectation to help test the phone.

I tried to run "sudo apt install tor firefox" from the terminal. But I got an error saying that neither tor nor firefox were recognized.

I seem to be able to reproduce this consistently - but it takes time to encounter this. I typically run Morph browser and let it play a youtube video. I just leave the phone on a flat surface with no movement whatsoever. In about 5-10 minutes, the screen changes from portrait to landscape automatically. I have not had a chance to test this on other distros yet.

I ran Mobian from an SD Card, and the headphone jack works fine. However, on Ubuntu Touch, the headphone jack does not work at all - not for calls or media. Same device when running Ubuntu Touch and Mobian. All the latest updates from System Settings were installed.

I'm on T-Mobile in the US with my Pinephone UBPorts Community Edition phone. I installed all updates from System Settings. But outgoing calls fail. Incoming calls seem to work.
