How to set up a VPN connection on Android with 100% protection against traffic leakage directly?

Question

Android

The problem is that the Android VPN/TOR/PROXY apps that I know of don't provide 100% direct traffic protection. If the application fails, then the traffic will go directly. You need a solution that multi-factorially secures Android from a direct connection to the Internet.

Answer 1

Use built-in VPN
