Android folks:
Here's what you need to know:
1. In voice recognition mode, for reliable recognition of keyword phrases I need 3-4 syllables so the vocabulary is "Start Calling, Next Maneuver, Previous Maneuver, Repeat Maneuver, Stop Calling"
2. In tilt mode, only roll works decently. I calibrate the position of the device when you start the caller, usually by the button on the wired headset, so before you click it, make sure you are in your normal flying position and that the device in portrait mode would be rolling when you tilt your TX, or whatever you have the phone attached to. I watch for a return to nearly the same position as the starting position to reset the trigger to wait for the next right/left roll.
3. I need a network connection to get the maneuvers, but I don't need a network connection for the voice recognition.
