I'm building unity app and having problems running it in Gear VR. The scene works fine in developer mode (without a headset) and not in real gear. In Gear VR after the splash screen, screen goes black and doesn't take any controls. Home and return buttons does not work also. The sound plays as if the scene was loaded and I can adjust the audio level. But the audio level icon isn't displayed on the screen as it usually does in other vr applications. Osig file is placed where it should be.
The device is Samsung Galaxy S6 running Marshmallow. I'm using Unity 5.6.2f1
