Controller Emulator connected to Headset Phone but no tracking

Messing around with Daydream for a gamejam, just loaded up the controller demo scene.

The controller is talking to the headset phone (Galaxy Core Prime and Nexus 6P respectively) and it says it's connected in the controller emulator app.

However the tracking ball that represents where the controller is aiming is stuck on the horizon unmoving no matter how much I move the controller phone. I've tested the accelerometers and they're fine.

Anyone have an idea about this?

 

I have the problem like you, did you solved the problem, if yes, could you pls show me how-to ?

 

The controller emulator requires a phone with a gyro, but the Galaxy Core Prime doesn't have one.
