/e/ doesn’t use the default camera app of linageOS, but doesn’t configure it replacement in a sufficient manner.
in contrast to “snap” “open camera” isn’t able to access multiple cameras of different focal length available some phones (e.g. on my MI A1). the reason for this behavior are mainly related to the fact, that open camera isn’t listed under “vendor.camera.aux.packagelist” in build.prop.
unfortunately open camera doesn’t support auxiliary cameras very well and will often show a wrong number of cameras and crash on accessing this unavailable devices after changing this build.prop-entry. i don’t know, how this behavior could be fixed, but i really would like to see a working camera solution on /e/, which doesn’t ignore the available hardware capabilities of our mobile devices in a very unsatisfying manner.
