I have been using adaway on KitKat ART and was working fine. Suddenly I see ads in my apps & all the websites in host file are accessible on browser too. But when I ping in terminal I get reply from the host file. Pls help. Permissions for hosts file are rw-rw-rw. And surprisingly I have this problem only when on mobile data. While on WiFi all the ads are blocked & host websites are blocked on browsers.
