Sadly, filtering is a privilege only rooted Android users may enjoy despite there being a perfectly functional iptables/ iptables6 instance on every phone. The first thing I do after rooting is install a front- end to iptables and set it to whitelist mode. Any app that has a genuine need to access the internet can then be authorised; everything else is denied. It frustrates me greatly that the ' common user' is denied this protection.
