I’m currently using “OpenVPN for Android”, and it mostly works, but the UI is very dated and hard to use (I can’t figure out how to delete a VPN profile), and crashes if it goes into split screen mode. Is there a better open source VPN client for Android that supports OpenVPN or Wireguard configuration files?
Jusy looked around, apparently it is indeed proprietary. Well this doesn’t make any sense why make a proprietary VPN client and call it OpenVPN? Anyway it seems like you are stuck with OpenVPN for Android dude :(
Well, OpenVPN is the name of the protocol, not the client.
