My phantom 3 went through 40+ flawless flights , some at very long distance, sometimes nearly a mile away from the controller with no issues. If it lost signal, it turned around and came back safely - the recorded video showed the drone turning around and coming back to me, the video file was not interrupted and looked great all the way. All was great! Then, something weird started happening, the drone loses signal MUCH closer to home AND when it does, it STOPS recording video (I see it on the controller, there is a sounds and the time stops)! Also, a third symptom is that the drone video files are now often corrupted with visible broken transmission, bars, messed up colours, etc which is weird as it is not the controller that records the video, but the drone itself, and previously for 3+ months, lost signal never created corrupted or interrupted video (which made perfect sense). What happened??? Again, it was working flawlessly for many many flights and now loses signal much closer to home (in various cities/places, not just one place, I might add), stops recording and messes up files. I have not changed anything, no new firmware etc. The only thing is that there may have been 2 weeks since the last good flights. Please help! Someone mentioned I might have to re-pair the drone with the controller, but I am still able to fly the drone just fine when it has the signal, so should I really do this? Many thanks for your guidance! Is it software or is my drone broken? BTW, when I have signal, the recorded video is perfect. But I lose it so quickly and then everything basically goes to heck.
