Chosen Solution
My DJI Mavic Pro gives Mech Err shortly after turning it on. I think this is becuade the left hand Joystick is damaged, it clicks downwards if slight pressure is applied. My question is can I fix this myself. So far I have removed 2 small screws located behind the phone holder but failed to open the case.
