OpenVPN tunnel disconnects frequently

That's your issue, you are specifying in the OpenVPN configuration the local port for the client to use. Since you are setting it explicitly to 4194, that means all phones on the network will try to use the same local port as source to connect to the VPN server.

The problem is that since your phone are behind a PFSense firewall, I assume you are doing NAT on the firewall. Most default NAT configurations get confused by multiple devices talking to same remote server/port from the same origin port.

Try either removing the lport setting, or specifying it to 0 (which means use random port instead of defined one). That should resolve the issue.
