I do not have a Tab S4 but i think it should work. Because trhe Tab S4 is just an Android Tablet . If you do not use DEX Mode an Tab S4 it should work as expected !!
But if you Use DEX an your Tab S4 , it will also work, BUT there are some unexpected behaiviors.
In example ZOOM.... You cant Zoom with your FIngerns and also not with your Mouse. There is a PopUpMenu (right click) --> View --> ZOOM + /- But this acts unexpected .
