I updated the phantom 4 to the latest firmware and ever since the gimbal has been acting strange for example, the was gimbal facing slightly down (not facing excatly forward) and when i spin the drone the gimbal goes all wack with the horizon not being straight and the camera faces upwards that even happenes when i am in tripod mode and spin the aircraft slowly. The Gimble drifts up and down when I adjust the camera height
I have tried the following: IMU, Compass and gimbal calibration, factory rest, downgrading the firmware (which didnt work casue i could only downgrade to the firmware that broke the gimbal in the first place). So right now the camera is completely unusable for taking video as it just doesnt look right.
Is their a solution to this problem please as I need this drone for security purposes on the farm.
