I've used a firewall on my phone: https://play.google.com/store/apps/details?id=app.greyshirts... The firewall is brilliant in that it sets up a 'VPN', that all connections must go through. Bam, no more notifications from any shitty apps that got a request from a marketer to annoy you. However, it won't help with the apps that you have a love/hate relationship with (ie Viber).

You will be SHOCKED at how many apps insist on a connection to the internet despite not apparently needing a connection. I even had apps I never use, still try to call home!

On a sidenote, I love how the app also gives Wifi or Mobile Data option. ie, prohibited updates unless over WiFi.

Last updated 2014, doesn't support ipv6 so it is pretty much useless in most countries?

Are there any decent no-root firewalls on android?
