Dji go 4 app locked up

[heydave23]

2nd day of flying this new machine, I was up 400 feet out about 1000 feet. I switched over to sport mode, took it up to about 42mph and then I lost the signal. I pressed the RTH button, then the screen went black and white and froze. I waited a little bit, then pressed the black RTH button on the controller. I was sweating a little bit, but the failsafe worked and my new drone landed safely. Did I do something wrong switching to sport mode mid flight? [emoji29]

I would try a different cable going to your phone or iPad. I switch in and out of sport a few times every flight
