I use the Fairphone 5 with /e/OS (1.18-t) but I’m new to both Android, /e/OS and this forum. I aim to decentralize my usage and prevent trackers and ads as much as possible. However, yesterday I was served some personalized ads in an app, which made me confused and curious how that was possible. After a bit of digging, I think this happened because both Reddit and the other app use Google Firebase Analytics, which probably leak my interests from Reddit. Anyways, while investigating this, I also found that Android AdServices are installed by default, as one of the core apps. Again, I’m new to Android so I apologize if this is a stupid question, but what is this used for and why does it come pre-installed on a OS which aim to prevent trackers?
Another question I have is, if I go into the microG settings, then Cloud Messaging, why can’t I turn it off? I can disable Notifications for every app manually to achieve “Status: Disconnected”, but I can’t disable it globally using the blue bar at the top. How come? Same question goes for the Google SafetyNet, where none of my apps seems to use it, but I still can’t disable it?
Thanks for more documentation. Unfortunately though, it doesn’t answer any of my questions. The solutions listed as “How to disable” doesn’t work (nothing happens when I click on the switch), hence my question.
