Though I don't have a pinephonepro to test but this issue is due to missing camera config. The megapixels package comes with config files for supported devices. You can try check this issue, https://github.com/Shubhamvis98/kali-pinephone/issues/24

@sonixa, did you try that pinephonepro's camera config?

i've added megapixels-config-pinephonepro package, it contains pinephone pro's camera config. You can install the package using apt install megapixels-config-pinephonepro.

that seemed promising but megapixels fails to load.

started from gui, it just tries to load for a few seconds then dies. no error message.

if i type mexapixels from terminal, then i get info. im just guessing its run command, i have no idea.

cant copy from or paste to shell. cant upload screenshot. site fails.

cant paste html error info, blocked by cloudflare
