WHAT!!!!???? I did not know this existed! Thank you.
I use a wireless Xbox One S controller as a shield remote. It works great; I also use it when streaming games from my PC to the TV. I tried the shield controller and was pretty unimpressed.
The newest nvidia remote is leaps and bounds better than the last.
I recently bought one of the new generation remotes. Order of magnitude better and only $30 (has a backlight and mix still!)
I prefer the remote control app instead, why find a remote when it can just be on your phone, y'know?
Because I can't feel the buttons with my thumb and have to look down, unlock my phone, switch to the right app, and then tap. It's a horrible experience.
Your phone is fine until you want to pause the movie to answer the door, but it takes tens of seconds just to reconnect to the TV dongle.
Or when you want to pause said movie because you're getting a call, which prevents you from pausing the movie. Happens to me all the time while Chromecasting.
Yet another reason to avoid using phones for phone calls!
