Hello I would like to ask a question I have a mavic pro. Which I fly with my cell samsung note5. But at some point I lose video signal. Which I should do. It is possible that it is due to the resolcion eh thought to lower it to 720. additionally I would like to ask if it is possible that the scroll to lower and raise the camera can react of constant way like the one of the p4

What flight environment are you flying in?
Watch this video on antenna orientation and it may help.
Also, the camera operates the same as the P4. The scroll wheel on the RC tilts the camera from straight ahead to straight down (and the option to go up 30° from level)
In the gimbal page there are settings to adjust the speed.
