One common excuse people give for rooting their android devices is to block annoying ads from popping up on their devices.

This indeed is a compelling reason as mobile ads, at best, can be;

  1. intrusive and distractive
  2. ruinously expensive as it burdens device hardware resources and also drain internet data.

Popular ad blocking apps like adaway and Netspector are only available for rooted devices.

For non-rooted apps, there are a few apps available on Google Play. They work, basically, by creating a mock virtual private network (VPN) for you and you alone and then connects your device to it. What this means is that all traffic you have coming in is through the app, and it protects all your data on its way out.

Notable among these apps is Lostnet NoRoot Firewall. WIth LostNet NoRoot Firewall you will be able
