Afwall+ Android Firewall for multiuser Hi guys After rooting my andoid phone to prevent excessive data usage by Android  system and installed AFWall+ that is based on iptables.
U have two users on device both account are handled by me by this It is easier to separte work and home profile separetly
AFWall works as supposed in owner mode but on switching   user Apps are not able to work (browsing,load pics do chats all stuff related to internet) but on again switching to owner mode I am able to browse internet
Go to Preferences/Experimental in Afwall+ (I am currently using v3.1.0), and enable Multi-user support!
