1. A method for self-diagnosing a mobile device comprising at least one or more actuators, one or more sensors and a display, the method comprising:
feeding a pre-defined control signal to a first actuator of the mobile device;
measuring, in response to the feeding, a first electric signal using a first sensor of the one or more sensors;
comparing the first electric signal to one or more reference signals associated with the first actuator and the pre-defined control signal;
indicating, in response to the first electric signal failing to match the one or more reference signals according to one or more pre-defined criteria, a negative diagnosis to a user of the mobile device using one or more of the display of the mobile device and the one or more actuators of the mobile device; and one of:
feeding of the pre-defined control signal to the first actuator causes activating and deactivating the first actuator following a pre-defined pattern if the first actuator is working correctly or causes producing an output having an amplitude directly proportional to an amplitude of the pre-defined control signal if the first actuator is working correctly; or
performing, in response to receiving a request for measuring a reference signal with one of the one or more sensors from a requesting mobile device, the following:
measuring a reference signal using said one of the one or more sensors according to the request; and
transmitting information on the measured reference signal to the requesting mobile device, wherein the request for measuring the reference signal comprises at least information on a unique identifier of the requesting mobile device, the method further comprising performing, in response to receiving the request for measuring the reference signal, the following:
demodulating, in response to the measuring of the reference signal, the reference signal;
comparing the demodulated reference signal to the unique identifier of the requesting mobile device; and
performing the transmitting of the information on the measured reference signal only in response to determining that the demodulated reference signal matches the unique identifier of the requesting mobile device.
