I just bought the Phantom 4 and when I set it up getting ready to fly it a message came up
saying weak radio Signal. and the aircraft is 3 ft away from the controller?
can someone help me please.

Does the message stay on the screen all the time, or does it just pop up occasionally for a second or so when you first connect to the craft?

I see the odd 'weak radio signal' when I first connect, but it only appears for a second or so.  Once all the remote to craft connecting is finished, it goes away and the P4 flies normally.

I replied to your other thread with the same issue.
