Hello to every one,
I have an issue with the camera of my Phantom 3 Professional, the quality of the picture and video are bad: in the white areas, I can see some oblique lines, and the videos/pictures are always full of purple and white dots (the dots are not fixed in one location). I tried to re-flash the firmware, change SD card, reset settings, and also changed format and video quality but the problem persists. I will attach some photos.

The drone never crashed and never got wet.

This is a video example from my drone (you can see the flashing dots in the middle)

Looks like the flat ribbon cable connecting to the camera needs fixing or replacing.

Yes, check all the connections in the gimbal/camera.
You're a brave man flying that close to the water surface!!
