I would like to know what an app can figuring out about other apps installed in the same profile. I know that Google Play Services (just an example) are integrated the same way as unprivileged apps. The app is controlled the same way like any other apps via the GrapheneOS sandbox. But what does this mean? Can an app detect my other installed applications?
adelina Can an app detect my other installed applications?
Yes. Any app can see other apps that are installed. If you're not comfortable with that, you can use user profiles. Apps in one profile cannot see installed apps in a separate user profile.
