I want to add myself to this list. I have a 55SM9000PUA which I just got, and screen share isn't an icon on the menu below, neither is it an app in the app store. I cannot find it either by going into my android settings>connected devices>connection preferences>Cast. I can't find a way to place the TV into Screen Share mode so that my phone can detect it. If someone has any ideas, please, Im all ears.
