Hi, i've seen similar issues being reported but no solution so far. Mine seems to be a little different. After installing the latest update, an image on my Phantom 4 pro+ screen disappeared. Everything else seems to be working ok, but the remote keeps telling me that signal is weak, or completely loses it. I check my frequency bars and they are all over the place.

Sometimes when I turn it on, the image on the screen is all green with glimpses of actual picture, like it's trying to transmit but has huge interference. I took it away from my complex and boom, no image again.

I bought it couple of years ago, but maybe flew it 10-13 times the whole time, i don't think returning it wont be an option at this time.
