When I go to Settings, apps, all apps I can obviously see all installed apps, including the ones installed by other users/profiles. It just says beneath these apps "Not installed for this user". Is there a way to hide other profiles' apps from this list?
Themble agreed, I don't like this at all. I had no idea one user could see the global app install until seeing your post. Hopefully this is something than can be addressed.
Themble The main owner profile can see all apps installed in other profiles. However, non-owners can only see the apps installed in that profile.
AFAIK, this ability is only limited to system apps, which by definition has system privileges. You can install apps like PrivacyBreacher to check that other regular apps cannot see apps from other profiles.
