Claim 18:
19. A computer readable medium comprising program instructions stored thereon for performing at least the following:
causing feeding a pre-defined control signal to a first actuator of a mobile device, the first actuator comprising a first vibrator;
causing measuring, in response to the feeding, a first electric signal using a first sensor of the mobile device, the first sensor comprising a first accelerometer;
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 a display of the mobile device and one or more actuators of the mobile device;
measuring of a background vibration signal using the first accelerometer when the first vibrator is inactive;
filtering, in response to the measuring of the first electric signal, the first electric signal based on the measured background vibration signal; and
performing the comparing using the filtered first electric signal.
