Einleitung
Replacing the camera assembly of the UDI U818A drone requires complete disassembly. The main frame is attached to the receiving board on the very inside of the drone. You will separate these two parts by unscrewing the screws in all four corners.
You should replace the camera of the drone if you notice a blurry image being received from the drone and have already troubleshoot connectivity issues, or if there is no image present at all.
