I am having same problem. I have had a couple crashes. So today I sat down to do a close inspection or rotors, and cameras. I found one rotor had small nick on back edge and another a small crack on back edge. I decided to remove them all, wipe them down and replace those two. When trying to mount one of the new ones I noticed it would not go on and the motor would not spin. Could not figure out what was going on until I looked closely at the mount pins on the old rotor. Two of the three mounting pins on the old rotor were completely gone--broken off and one of the pins was jammed in the motor. Pretty amazing because I think I had flown one or two long missions since the last crash. Quite the robust little drone. Lucky that prop stayed on. Anyway--hopefully the micro shake glitch will be gone now. I have not had her back up yet but I would imagine that has a lot to do with it.
So people--check your prop mounting pins--there are three that lock into the motor plate when you press and twist.
