So I recently purchased a dji mini pro 4 to complement my hiking. I noticed that their is a white line in my videos and photos at is sometimes their and depending on the brightness of the subject seem to go away on darker images. It sometimes flickers and dosen't completely traverse the entire screen. It does it while recording and not recording. When I zoom out it goes to the side and exits the screen. Then returns case i zoom back in. I will atach photo. Please help me go in the right direction.
