So, once turned on, Android will send all IP traffic to this app. Packet Sniffer packets make use of the above mentioned feature. The VPN app then usually encrypt those packets and send it to the VPN server, from where the packets would go to their original destination. When an app tells Android that it wants to provide a VPN connection, Android will forward all IP packets destined to internet from all other apps to the VPN App. How a normal packet sniffer (that do not require root) works on Android.Īndroid allows an app to act as a 'VPN Gateway app'. If your packet sniffer application does not have an option to turn off SSL packet sniffing, in that case uninstall the app, remove any custom CA certificate installed and then re-install the app.

But you will still be able to see the source and destination address of the packets. But you won't be able to decrypt the contents of packets sent over an SSL connection. Even simple rooting can not solve your problem.

The reason why this problem occurs is the existence of 'Certificate Pinning'. There is no complete solution for your problem.
