Ok...sounds like a crazy question and can't really seem to find an answer. I dumped my Nexus 7 and have been flying with my Note 5...works much better, but still get those **** green video lines occasionally. I keep my data active and phone on and it has been flying fine....BUT today I just thought...what happens if somebody calls me? i got concerned because I was testing Litchi out and my phone rebooted twice...each time I was plugging in the USB cable. Thoughts? Should I cache the map? Then exit app...put in airplane more, then fly??
