A:AnswerHey there, Bud. Thank you for reaching out! To answer your question, this device can be cast "to" from the Family Hub on our Smart Fridge line and our phones as well as any devices capable of using the Samsung Smart View app. The TV itself also has several smart applications that can be used independently of a connected device. We appreciate your interest in our products! Have a good day.
