As I said in this Forum Post Exit Button in Android VR app - XR Development - Unreal Engine Forums
I have searching something related with that in others posts but I do not found anything.
I don’t know if it only happens to me but when I package an app with google VR, the only button of the screen that works is the engine wheel but not the “X” button for exit from APP.
How can I activate this fuction? and how can I change the interface of Google VR?
As an other user who answered me, it only works if you are using Daydream but not when you use cardboard option.
Thank you very much.
