I've installed and tried both these apps, both use a VPN connection to "filter out" data usage (WiFi and Mobile data)... they also include logs of attempted connections with IP domains included.

However, when I block system apps such as Android System and its sub-apps, they still accumulate data. While some attempts for connection to Android System apps are shown in the log and blocked, some must be getting around it...because I check the Data Usage for Android System, and it constantly climbs even while "blocked" from data access by the firewall VPNs.

Anyone else have same issue? Is this just an inevitable flaw if you don't have root access? Is this possibly due to spyware which is somehow overriding?
