Greetings fellow DJI fans / sufferers,
I have been having some intermittent issues with connecting the RC to my tablet thingy (yes I am that technical) and initially thought that it was a faulty lead.  Having tried a few leads over the last few days I am now wondering whether the USB port on the RC is faulty and thought I would ask you good folk whether you have experienced similar issues - and whether the problem was indeed the port rather than the lead.
Many thanks.

When you plug the thingy from the RC into the thingy on the display device, what doesn't work, is it the thingy showing distorted or broken video ? (tried to keep it non techie)

I'll say P3P RC connecting to an Android display :-)

Lol Aardvark,,,I say thingy from IOS display.  Winner wins a beer.

I would recommend you to hold the C1, C2 and shutter button to reset the RC. If no helps, changing recommended mobiles and original working cables will be helpful to verify whether the port damaged.

Many thanks all.  I seem to lose connection to the tablet completely from time to time and this is restored by gently moving the USB lead within the RC socket.  Thingy.
