Lost image in iPhone but on RC has control

[pai]

Hi today was flying around and when I connect my phone (iPhone 7 plus) to the RC at the beginning has no issues but after maybe 3 minutes (occur around 4times) loss image on phone, no gps , no signal , but on the RC still have control over Mavic and has gps everything looks good. I delete the app and re install again the same issue , unplug and plug the USB again no luck , later on had no issue with my flight , do you guys think maybe is the USB cable? I flew about 15 minutes and no problem, that's weird.

Sounds like a bad cable. Try another cable.

I use to have the same problem with my iphone 6s. The new firmware update has resolved the problem. Has never happened again.

I had the same problem and found that if the rubber "holders" were covering the iPhone's home button it would loose video signal. Don't clamp the phone in so tight and try it again.
