So, mobile VR! :slight_smile:

What system are you using? cardboard, daydream? or more in the area of oculus go / oculus quest?

Are you trying a scene from the playground, or is it your scene? any chance of seeing it?

Seems like this is a bug with the double-tap feature. I am working on solving this, however -
if you dont want the doubletap feature, you can disable it using the exitVROnDoubleTap flag. so, vrHelpr.exitVROnDoubleTap = false will eliminate this feature.
Regarding the missing button, calling vrHelper.updateButtonVisibility() after leaving vr fixes the issue, but it should be a part of the process and not an external solution. I will submit a github ticket for that.
But agin, if you dont even want the doubletap, just disable it
