VR Help Needed

Basically, when I play my game in VR mode on my Android, there is a small ‘X’ in the upper left hand corner of the screen. When the user presses the ‘X’ without wearing the glasses, it should go back or quit the application. But the ‘X’ is not working. I have tried everything, but I can’t get it to work.

If anybody could meet me on Skype to guide me through this, that would be great. I could pay via PayPal.

Are you using GoogleVR or native Unity? What version of Unity, what version of GoogleVR?
