I fly a P3A and although I understand there are software glitches that cause loss of video signal that have been addressed with 2.8.3. If you still have problems with weak signal or complete loss try this:DJI says it is the Apple cables. "Not reliable". Anybody know of an alternative to Apple OEM cables??
Get your P3 ready to fly , instead of take off procedure move the USB plug or bump it.
See if that causes signal loss or weakness.
That is my main problem, I get weak or total loss just by simple motion of the USB cable hanging and moving around. There is too much play. OEM apple or others just have too much play and allow for movement.
