Android phone as 4G proxy server

I am trying to turn my old phone (Xiaomi Mi 5) into a 4G proxy server which I can use with different apps for scraping data, etc. I have been searching on how to set it up and I found some articles, but they are not very clear. I am really a newbie and I have no idea how to set it up. I have bought 2 Android apps: Proxy Server Pro and Servers Ultimate Pro having trouble configuring it. These are the steps I have followed on Servers Ultimate Pro: - Add a proxy server - In the General tab, I didn't touch anything - In the Rules tab, added a new rule - HOST CONTAINS: I put my public IP address which I found at https://myip.com - REPLY WITH THIS IP: 127.0.0.1 Port: 1080 Now, when I try to test it I, get no connection.
