How to set on avg firewall on android phone

Hello, Zoran.
Please note that firewall works on rooted android devices only. Rooting is a process which allows Android users to attain privileged control of their devices (known as root access) within the Android system. Rooting the device allows the user to override limitations that carriers and hardware manufacturers put on some devices. This makes it possible to alter or replace system applications and settings, and run specialized apps that require administrator-level permissions.

NOTE: Rooting your device will void its warranty.
