I too noticed the odd blank image and had to land and power off the camera in order to get it working.. I had the latest firmware, but not sure if it was related to a crash that I had which bent/broke the connector cable on the camera which I had replaced. After replacing the cable I had camera again but no satellite/battery/distance displays, it just showed "N/A" and after a few weeks of very few emails back and forth from DJI who wanted screen shots? (not sure why when I explained this) but after that I had enough. Since I had purchased my unit through Amazon and it was still within the return period, I returned/replaced with a new one. What a wonderful experience I had with Amazon. They even shipped the new one with 1 day shipping for free and then reimbursed my return shipping once they received the original. IMHO the problem was within the camera as the camera has the wifi antenna but DJI would not give me a firm answer on this. I had even gone as far as purchasing new GPS and Compass as well as the complete cable package but before I got too carried away, knew that replacing the cables should be all that was necessary. Considering the $$ you are spending on a Vision, it should not be as difficult as it is to get some serious tech support.. very sad.
