Hi there, I have a S20 and recently, when I plug my Samsung TV HDMI in to my phone, it automatically switches to DeX.
From memory, this wasn't always instant.
I have gone in to settings and ensured the DeX "auto start when HDMI is connected" is toggled off, but it still does it every time!!
I've updated my phone, so I'm at a bit of a loss now.
My screen is intermittent, so I can't always easily press the home button on my phone to exit.
If someone can advise how Iactually get it to stop running automatically, I'd be very appreciative :).
