No microG but GsfProxy, interesting. Maybe the Calyx setup wizard only disables it and it somehow got reenabled, not exactly sure how they implemented that
In any case, since you are running Magisk, I’d just create an overlay module to remove those apps, easier to revert if things go sideways.
- Create a folder for it
su -c mkdir /data/adb/modules/NoG
- Create empty subfolders for gsf
su -c mkdir -p /data/adb/modules/NoG/system/product/app/GsfProxy
and have it replace the system onesu -c touch /data/adb/modules/NoG/system/product/app/GsfProxy/.replace
- Remove the updates for Google Photos
pm uninstall-system-updates com.google.android.apps.photos
, check it’s pathpm list packages -f com.google.android.apps.photos
and repeat the previous step with that information - Reboot, check if both apps are gone and try installing Gcam Service Provider again
