Everything is working fine and dandy... tracking, recording data... then all of the sudden location shows at 0.000000° When tracking first starts everything is fine, usually after a "while" it starts showing 0.000000° and the device in the middle of the ocean.
Looked at the logs and the data checks out and showing good Lat Lon speed and course in there.
