Hi, I've followed the steps in https://library.vuforia.com/articles/Solution/Integrating-Gear-VR-and-the-AR-VR-Sample-in-Unity-5-3-and-above. The app starts, but I can only see a yellow button or circle, on a black background. I've started directly on Vuforia-3-AR-VR scene. I'm working with:
Unity 5.4.0f1 (64-bit).
Samsung Gear VR with Samsung Note4.
Am I missing something?
