I am using a Freeflight 978 Rx. This problem seemed to start when I upgraded my very old Samsung tablet to the Samsung S6. The old table was rock solid with the Freeflight. The upgrade to the S6 changed tablet hardware and Android OS versions. Since there was no change to the Freeflight, I assumed that somehow iFly was not happy with something in the table hardware/OS.
My symptoms: The GPS status box would switch from ADSB to the internal GPS. Radar presentations would be pixelized and patchy. Within a few minutes, the connection would be reestablished, and information updated. Then a few minutes later it would drop out again. This would continue for the length of the flight.
I'll get you a log the next flight.
