What do i do this happen from one flight to the next, there is no one that want's to help.It seem to me once they have your money the problem is yours, you sort it out !!!!!!!

Can you post some examples of the pictures, makes things a bit clearer as to exactly what you are seeing.

It seem like your drone camera have dead pixel on its sensor. These problems always happen in DSLR cameras.

Like Aardvark mentioned, please post some pictures for better assistance, we'd like to help.

Thank you to every one's reply on my request, i had no joy with dji, had it fixed, had to replace the gimbal and camera very expensive for a drone that was only 8 months young.
