I dont know what that is for,I'm still learning.
It's still there. I believe it's called "connect" in the pull down. You can also download the Smart Things app. If you have a Samsung smart TV you can project your phone on to your TV or vice versa.Did Samsung drop the screen mirroring with your smart tv prospect with the latest phones?
smart view is not that smart. I have found it will only connect to certain devices. it connects fine to Roku but not much else without a Samsung smart hub.
in the connect settings it gives a list of devices.
