Eid, tried your suggestions. Worked like a charm. I'm able to control my phone from the PC.
On phone I installed: the app droidVNC-NG (Server)
After the permissions it automatically provides the server and port which to connect to.
On Zorin I installed: remmina (to use as a client)
Used the serversettings provided by the droidVNC-NG app.
Was able to fully control my phone and make adjustments or handle a phone call. Great suggestions. Thank you for this one.
