I am playing around with creating a VR app. I made a basic scene using the latest Unity version, built to the android device, launched it and it worked with the gear vr.
After I closed the Unity editor and tried to open my saved project, the editor crashes.
Are you on OS X? If so, be sure you have the latest Mac runtime installed, 0.5.0.1. If you have an older version, please uninstall first before installing the newer one.
