Installing a firewall app and checking the connection log on my Android phone really spooked me. There's a ton of traffic in the background that shouldn't be there. It's absolutely crazy that Android doesn't have a first party firewall or the ability to disable internet access permission per app, but that would impact Google's ad revenue, so of course we can't have that.

- Anarch157a 7y agoI don't know if this is a feature of Android or of the alternative ROM I'm using, but I can disable network access on a per app basis. In my Android Pie based ROM, in Settings / Network & Internet / Data Usage / App data usage I can select any app and disable WiFi, Cellular data or both.
