Is it possible to use your phone as a trackpad when using DeX in Tab S4? That would remove the need to carry a bluetooth mouse around

Why do you need a mouse, it's a touchscreen plus you have a stylus acting as the mouse.

You need a mouse or trackpad in DeX mode, if not it's pointless as a productivity machine

I have not read about using any smartphone can act as a trackpad with Dex on a Tab S4. Only the Note9 can act as a trackpad while it is hosting the Dex environment on another screen.

The best thing is that you can use the touchscreen or stylus or mouse or trackpad in Dex mode. All work good as each other.

Using Dex mode with the stylus is great and how I use it a lot on my Tab S4.
