Hi guys, I have been pissed off about this lack of FPV on the phone. Getting error messages and doing all the right things and still no joy. The camera can still take videos and still shots but nothing on the phone FPV. I just fixed my problem and hope this can help other people with the same problem. Open up the range extender and check the 2 connections that go to the flat square antenna. They are easy to see and deal with. Make sure they are securely down on the 2 posts. Mine were looking secure but if you move them, they were not. Secure them delicately and you should be good to go.
