What programs exist for managing a mobile device via Wi-Fi?

Question

Android

Tell me a program to control a mobile device via Wi-Fi. You need something like a radmin, but for a mobile phone. Not through the Internet. It is desirable to have clients for both a computer and a mobile phone (but it is possible for one thing, if not for both).
Case: I live in the country. As a Wi-Fi router, an old Android 6.0 phone is used, glued with a white roll-up plaster (suddenly, it holds well) to the terrace window (the signal is better there). I want to manage it from a computer or mobile phone via wi-fi, and not run to it for any sneeze like turning on VPN.
Is there something that works through LAN, not Teamviewer?

on the LOR. Absolutely exactly what I need. It works, however, only on the desktop, but otherwise - the very thing.

Answer 2

There is such a program as VMLite VNC Server
Here is its description from one site:
"With the help of VNC Server, you can connect to your smartphone from anywhere in the world, but it is worth noting that the application has many complex settings and it is paid. But the program turned out to be really powerful. Its own it performs the function five plus.As in the case of Vysor, you first need to enable device debugging via USB.Next, you have to configure several settings and pay 690 rubles for the application in the Google Play store.Then connect the phone to the computer via a USB cable, run a program on the computer that will automatically download the necessary drivers for Windows"
