A:AnswerI don't think it is possible. I returned the tv because I couldn't access amazon prime via Google cast because the icon for it is not located in the Amazon prime app. I got a Samsung that has a smart hub where you just download the apps you want on to the smart tv...you don't need your smart phone. works like a charm!
