Sometimes my drone's camera will cut out and not have any live video of what it is seeing. And all the other important info like height is N/A and pretty much has no info. But will still fly manually. But if I turn it off and on again, it may appear again. I just wonder why it may do this sometimes. Also another question about calibrating the drone GPS, where you spin in a circle. I've seen people do it on YouTube vids where the drone flashes yellow, user does a 360 with drone in hand. Then does it one more time with it tilted. What does this do? The drone seems to still have GPS signal when I don't do it, and it may flash green. Also encountered a low signal or interferrence when I flew the drone up super high. The video was still showing but gave me that warning. Should I take it seriously and land it immediately? Thankfully it was still within the field I was in rather it being a mile away. What happens if you get low signal warning if the drone was out of your sight and like in another block of the neighborhood?
