downloaded an October 2022 dev image of Manjaro phosh:

Manjaro-ARM-phosh-pinephonepro-20221008.img.gz

and installed megapixels-ppp

works!

the default rear image is 1048×780, but modifying the file

/usr/share/megapixels/config/pine64,pinephone-pro.ini

one can change the resolution. Is a bit darker? did click and change the camera settings for shutter and iso, from defaults.

here is a full size image (my messy table with a glowing mouse)

Below, for comparison, a picture from the older ppp-cam utility, still showing the triangular dots, but seemingly better focus.

still not quite working with cli; without Megapixels, does not seem to initialize properly…
need to dig into how metapixels and ppp-cam initialize things so cli commands work.
