I'm having a weird problem. When I try to mirror my Redmi Note 4 screen to my Samsung Smart TV, it works fine. But the second I play a video on Netflix or Hotstar (an India-based streaming service), it doesn't show up on my TV. I just see the notification panel at the top. The rest of the screen is black, even though everything's fine on the phone. The weird thing is that this never happened on my Moto X Play. I could easily watch content on these sites on my TV via screen mirroring. Can anyone explain why this would work on some devices and not on others?
