I feel insulted!
Just got Google's Daydream headset, connected controller to my Nexus 6p, ran my own game and NOTHING!
I used another phone to emulate the controller. Now I have actual controller, but it doesn't work because google doesn't support my phone.
I can't download the Daydream app which seems to be the only source to manage the controller. I'm looking for solution how to hack around. Suggestions please?
