Spaces is still very early, so there are some application lifecycle issues that we're working through with it. Please excuse our dust, and let us know if this guidance helps. Thanks!

Followed all the instructions and set up the Motorola with the headset.
Every time I try and use the samples app, it shows the menu on the phone with the menu button disabled (greyed out colour) and select button. Nothing happens after that.
I tried a build from Unity and I get the same result.
How can I go about resolving this to test on device?
