I can't figure out how this furshlugginer app works. I can't find it in my app library except by searching. I can't figure out where "Link to Windows" is except by searching. I can't figure out when to use a PIN code or when to scan a QR code. I can't figure out HOW to scan a QR code. On those rare occasions when I accidentally get it right, more often than not I get an error message that it's been disconnected, or I should unplug my phone and then plug it back in - which does absolutely nothing. Samsung DeX works much better than this arrangement, except that Your Phone purports to have functions that DeX lacks. But I can't tell if that's true, because this app has got me completely flummoxed. And I'm not inexperienced with computers.
