I’m unable to disable that app (app.grapheneos.camera). Its greyed out. I assume I did get a prompt initially asking me to “Complete action using Camera” and I hit “Always.” That was before I found and installed the Google camera (com.google.android.GoogleCamera). So I’m still stumped how to alter that double-tap “Open by default” to a different, non-built-in camera app (and I can’t seem to find anything in settings). Not a huge deal, but it would be nice to know. Thanks all!
