Somehow I got into a mode where apps selected were intended for deletion . I did not realize that and the camera app got deleted. I have not made any changes since that happened. What can I do to either recover or reinstall the camera app?
This is a Xiaomi Redmi 8A running Android 9. It is not rooted. As far as "how /when did it happen" I do not know more than this: somehow it ended up that ALL applications were selectable with a white round circle and asking "DELETE apps" or something similar. I had never seen that mode before (or since). I tried to get out of that mode but ended up with accepting the Camera that was selected and got deleted.
On and off I do connect Android Studio to the phone - for pushing a simple Ionic app to it. Does Android Studio have some mode that allows bulk deletion of apps on the phone?
