What Pine Phone Operating System For A Daily Driver?

[calinb]

I'd say:

1. Mobian, maybe Manjaro too, but not sure.
2. Every distro allows you to write documents.
3. Probably none. Mobian used to have a decent camera app, but the first app stopped working and never got fixed ever since, then Megapixel came along, and that too is no longer working with no fix in sight.

I'm pleased you reported (below) that you fixed Megapixels. It started working again for me after a recent Mobian apt dist-upgrade. Upon first launch of Megapixels, I still need to toggle between the back camera and selfie camera to correct the initially distorted image aspect ratio from the back camera though. After toggling the camera source in Megapixels, the image will be okay until after the next boot.

Sadly, about the same time my camera started working again, my phone program became very unstable and I must toggle the modem off and on to obtain or re-establish a cellular network connection. When I boot the older version Mobian from my Megi multi-boot SD card, the phone program works normally. (My up-to-date Mobian system is on eMMC.)
