Initially I had turned WiFi ON on the phone after turning the RC and Spark on. I got a short message saying Updating Basic Fly Safe Database, but nothing after that. I hooked up the OTG, which is my usual configuration (along with Airplane mode ON and WiFi OFF) and went through the various menu pages looking for the Precise Fly Safe Databases, but they were not listed. Even on the stock Go 4, I rarely got update notices for these and I live very close to the edge of two Class D facilities. Not sure why I got "NA" (not applicable?) on the Aircraft and RC firmwares, but until I learn more from others, I'm not worried too much. Btw, yes, I'm using a Samsung Galaxy S6+ Edge with no SIM card in it, just check for updates via home WiFi.
