This info is quite old at 3-5 years old. First the definitive & original afaik NetGuard what is it at XDA. The experts are at XDA & this here isn't that. It's just a quick blurb & links. [APP][6.0+] NetGuard - No-root firewall By M66B, Recognized Developer on 25th October 2015, 05:33 AM https://forum.xda-developers.com/and...ewall-t3233012 I looked at NetGuard again because after a factory reset I'm setting up a unrooted LG G4. I wanted an ad blocker & a firewall. And most require being set up as VPNs. And Androids only can have 1 VPN connection. Then ping ponging around I found NetGuard can block ads with a host file. But not the NetGuard on Google Play Store that one is crippled per Googles not listing ad blocking apps anymore. That's the mistake I made years ago, getting the borked version instead of the pure at Github or XDA. So far the hosts file is working well except a couple apps wouldn't function so I expanded the NetGuard listing & deselected "Apply rules & conditions". Then those couple apps worked again.
