Hi, we're sorry for the inconvenience. I would like to ask if you manage to update the firmware of your Mavic Air? Did you try to reset the camera settings? Have you tried to remove the SD card in the aircraft to see if there will be changes? Did you check if the RC could still control the gimbal? If so, have you tried to take photo/video and check if there will be a file that would generate in the SD card? You may consider using a different mobile device to isolate the situation, however, if the phenomenon would persist, we would recommend contacting our support using this link: www.dji.com/support for further evaluation of your unit. In the mean-time, you may refer to the video below for updating the firmware.
