I just got a Mi box S from Walmart, and I'm pretty happy with it so far. VPN works like a charm and app switching is pretty smooth. The only complaint I have is about Netflix! It plays a preview of the movie/series if I hover on a thumbnail for more than 2 seconds. It is incredibly annoying for someone who likes to read the description. Is there a way to make this stop?
It's not just Android TV exclusive in my experience. I've seen it happen on a relative's Roku and even their Samsung Smart TV. Sadly as far as I am aware there is not a way to turn it off.
