I am used to GCam as it makes much better photos than OpenCamera (which is standard in /e/) esp. in low light conditions (HDR+).
I just experimented a little bit and now I am happy with this:
- download and istall manually Gcam_8.8.224_V5-MWP_cloned
- install GCam Service Provider to use the preview/gallery-butten in “photosonly” version
And for now everything works - except the zoom (as this is a problem /e/ has to solve on OS-side) - collected here.
