I've been using google cardboard a lot as of late to watch my media via my Note 4 in Virtual Reality 3d. There are some decent apps for this, but none so far from what I can see with the ability to stream media to my phone. My favorite app the 3d application so far is Full Dive.
Has there been any thought to build native support in to the Android Media Browser app to view streaming media browser content and 3D movies to a smart device in a sort of Virtual Cinema view. I think this would be a great addition to this already amazing product.
