I have a phantom 4 and previously a 3 pro which I used a galaxy tab A with. Now I bought the Nvidia to use with my 4 as the tab A won't recognize the aircraft. I've tried the Nvidia about ten times and it crashes every time I fly. I have been using my iPhone 7 now and it's great. I did buy Litchi for both platforms also and same result. Any ideas or help? I like the tablet but hate the crash.
