I am new to the forum.
I have a Phantom 4 and it has been perfect for 14+ months but a couple of days ago I carried out a shoot for a customer and the photos were virtually unusable.
When the files were opened up in photosop or camera RAW the highlighted areas were missing and there was bad pixelation (dead pixels)in the dark ares and all there was were lines in the highlights no detail at all.
I uploaded the latest firmware, downgraded the firmware,upgraded again, deleted and re loaded DJI go4 app, factory reset camera setting and I stillhave the issue
Here is an immage showing the problem. Any ideas?

Complete name                 : C:\Users\.....\JI_0065.jpg
Format                                 : JPEG
File size                                : 181 KiB

Image
Format                                  : JPEG
Width                                    : 600 pixels
Height                                   : 450 pixels
Color space                          : YUV
Chroma subsampling         : 4:4:4
Bit depth                               : 8 bits
Compression mode            : Lossy
Stream size                          : 181 KiB (100%)

So, that says you either processed the original image to be able to display it on this forum, or you simply grabbed the JPEG thumbnail image out of the raw file. Or perhaps got it from your phone or tablet, in which case it appears the over-exposure zebra warning is switched on.

Either way, it does not tell us anything. If you want us to take a look at the photo and offer assistance, then you need to upload the original camera image to Dropbox.

I messed up some fantastic fall pictures/videos because my ribbon on my P4 went bad. I shoot raw stills. All my filming had hot pixels and lines in the bright areas. The P4 flew great and all the mechanics on the camera worked fine. I not sure if this is your problem, but replacing the ribbon cured the problem.

Thanks for the heads up I had not thought of that I was assuming that it was firmware or the camera had ... itself.  Perhaps i will replace ribbon I will post the outcome

OK, that is a hardware fault in the camera. Often it is a faulty flexible ribbon cable connecting the camera to the aircraft electronics.
