Good day. I hope there is someone that can help.
I have a Phanton 3 pro and just one day the video feed just disappeared. The Drone can still be controlled, but no feed at all.

The weird thing is, with no video feed, there is an Histogram  and it change accodring to the exposure and ligh, meaning, it see something, but can get a video feed. I have tried 2 different phones, but no feed (just a black / grey gradient background). I hardley used the drone.

Please help!!

Thank you for your reply.
No, no hard landing or any crash of any kind. I hardly used the drone.

I found one video on the internet suggesting that it could be something to do with the Lightbridge firmware, in a possible firmware failed issue.

Maybe there is a better way to reload the latest firmware on both the Drone and the controller.

I tried both Android devices, Samsung S5 & S9.
