black lines

I recently bought a used phantom 4, and after looking at the video I noticed that there are black verticle stripes running through the video. I did some research and reset all my camera settings and updated the drone, but the problem persisted. I turned over exposure warning off and the problem...

Getting black vertical lines whenever I'm pointing the camera near the sun (as seen below where the black blob is) or where the video is being over exposed. Is this normal!? This is NOT overexposure warning... these black lines show up real-time AND in the final video. Is my camera defective?
