On a flight, it stopped playing audio from my Nexus 10 tablet.
The tablet said it was connected and BTunes said it was connected, but no audio went through. I rebooted BTunes and the Nexus 10, but it didn't fix it. A wired connection worked.
Walking through YVR, I had the same problem as before. If my phone was in my front left pocket, it was fine. If it was in my back rear pocket (where I like to keep it), it was extremely choppy and unusable.
