Has Anyone had the video signal on the android app. go black while airborn? mid flight today my video feed went black,,, i still had telemetry data and radar position functioning but the video was black. just prior to this I noticed the video locked up while recording,,,I landed, powered everything down, exited app. re-connected, re-calibrated etc.. then re-flew with no issues this was about my 16th flight....not sure what the issue was, i was 450' away over water,,a little annoying....but other than that this unit works as advertised....all updates have been installed,,,the adroid app. was updated two days ago...
