The buttons are approximately at the same level as the housing. The stroke of the buttons is very small, but the switching is at least noticeable.
However, I don't think that a reset helps in this case. If there is no reaction of the front LED of the camera and the gimbal works then most probably the power wire to the camera is broken. It is a 4-wire cable with slighly thicker wires than the others (motor or sensors wiring).
If the front LED shows something but remains white then I think the WiFi board is broken.
If the front LED goes green blinking but no WiFi hotspot is available then the antenna may be the source of the problem.
