OpenVPN problem with Android device

Hello, I have bought a cheap UBUNTU server at $3.5 to install OPENVPN on it and it worked well. I tested and the server speed is very fast for both UP and DOWN over 50 Mbps but on my ANDROID device where I installed the application of OPENVPN the DOWNLOAD speed is very slow. 0.2 Mbps DOWNLOAD versus 3 Mbps UPLOAD speed. I searched online and it looks like there is a need to tweak the OPENVPX settings AND the .OPVN file that is downloaded to the ANDROID device. I think the following lines should be added (but I am not sure if this will fix the issue). sndbuf 0 rcvbuf 0 push "sndbuf 393216" push "rcvbuf 393216" I did not find how to edit the .OPVN file that is downloaded from the UBUNTU server directly. I need you to make this work so I can use my VPS server on my ANDROID device at normal speed (minimum 3Mbps download). My home/office connection is 10 Mbps so it's not nornal thast the download is stuck at 0.2 Mbps. I will send you the following info when you accept the project. 1) Server root login 2) OpenVPN admin and user logins with URLS to login I think you need an ANDROID device to test that it's working but if you can do without, you can bid. Thanks!
