Welp! Ladies and gentleman the worst issue with firmware yet. I flew my Phantom 4 on Saturday (6/4/2016) just for fun. Everything looked completely fine. I even have the footage to prove it. Everything was smooth, no crashes of course. I landed, put my Phantom 4 into my GoProfessional Hard case, took it home and left it in my living room. Haven't flown it. This evening (6/6/2016) I ran to my aircraft to update the firmware to have sharp videos once again, and immediately after updating firmware, I noticed a horrible black spot on the right side of the camera. I downgraded firmware, refreshed firmware, reinstalled, everything. I cleaned the filters, took the filter off, cleaned the camera, repeatedly, took a flashlight to it, it's completely clean. There is no getting rid of this spot. I am devastated and upset. This will be the second time I have to send my drone in to DJI. Thank god last time it only took 6 days, but now more than ever I need it for some jobs. I'm so frustrated. Here's a video of the issue. I cannot take apart the gimbal because I have DJI care and I don't want anything to be voided.
