Since new, 6 months usage, I have occasionally had the camera freeze in display. When I have the machine a few metres away, or really within eye site, I can see the camera move when I control it, but the picture in my Galaxy 4 remains frozen. I can still record, but unsure what I am looking at. I have to move the camera though rotation a number of times to get a connection to work, even then, not all the time and have to land and repower up the aircraft. And like all faults, it won't do it when I need to show someone. I have checked all cables, and tried another phone - same result. Anyone else have same issues?
