the chance the sensor is stuck on the printplate is big. In my cellphone it's loose, if you take off the cover you got the sensor in your hands, if you put it back on again the cover presses the sensor contacts on the contacts on the printplate. Easy. But i don't think they use this tricks on a webcam as you don't have to open it for cleaning out dust etc.

EDIT: And still, for turning it you should have wires, else if you turn the sensor the contacts won't be on their place
