Frostily7047 Wondered what the advantage was. Google play services will constantly be running since owner is always running in the background.
No! That was the reason why I haven't give it a try earlier…
But since I saw Josh's great YT video and finally have tried this setup (owner profile for install only, with Obtainium and sandboxed Google Play Services, the rest in another user profile), I have realised:
Google Play Services are not running, while I am using the user profile! :-)
I also used to think that it would consume far too much energy if I only used the owner profile for installation and then Google Play Services would constantly run in the background when using a user profile.
But strangely enough, Google Play Services do not (!) run in the background if you install it as Josh shows in his video.
Short version:
Install the required apps in the owner profile, but do not give network permission and deactivate them immediately afterwards!
Then assign the desired apps to the desired profile in the user administration.
Complete app configuration (incl. permissions) is then only done once in the user profile.
So: in my owner profile, apart from the 12 GOS apps, only AppVerifier, Bitwarden, LocalSend, Obtainium and Play Store are shown.
No (!) other third-party app remains activated in the owner profile.
I also didn't know before, that you can see and assign installed but deactivated apps in the user management.
Works great with a single user profile.
Better than using the owner profile 'normally' and one or more user profiles in addition.
