Google VR (Daydream) controller demo on Galaxy S6
You can connect a Daydream controller emulator app from Android (such as Galaxy S6) and iOS devices, not Android N on Nexus 6P, with small modifications of GVR scripts on Unity.
I don't upload this Unity project because you have to hard-code your phone's IP.
But it is very easy, and I described how to do that in the below page.
