I understand that certain apps utilize GSF for things like push notifications, but I would like to understand more fully how GSF can potentially interact with apps installed through the Play Store.
Let's say I install and enable GSF and the Play Store with only network permissions for each. Then, I download Google Camera with network permissions disabled. What kind of interactions are taking place between GSF and Google Camera (if any)?
Another example, but this time with network permissions enabled: Spotify. How does GSF interact with Spotify and for what purpose? What kind of information could an app share with Google through GSF?
I have checked out other posts in this forum related to GSF, but haven't found anything definitive. Thanks!
