Use all the Cardboard apps, I started with Google Cardboard because I could not get the Gear VR. Now that I have the Gear VR I use the cardboard apps and don't plug in the USB, for me works fine.

Try the 2014 Sidney New Years app. Run the app and pull the menu down, select 360° and start a video, tap the little cardboard icon when the video starts, slip the Note 4 in the Gear VR but put the USB away from the plug. I use a BT mouse to control things.
