1. A method comprising:

  • determining, by a system including a processor, whether measured parameters are valid or invalid based on a phase threshold analysis, wherein the system is integrated in a communication device;

    adjusting, by the system, a tunable reactance circuit of the communication device to a first tuning state according to the measured parameters responsive to a determination that the measured parameters are valid; and

    adjusting, by the system, the tunable reactance circuit to a second tuning state responsive to a determination that the measured parameters are invalid, wherein the second tuning state is one of a default tuning state or a last known tuning state for a use case of the communication device that was previously determined valid,wherein the phase threshold analysis is based on detecting an erratic shift between a subset of the measured parameters that is greater than a phase threshold, and wherein the determination that the measured parameters are invalid is based in part on detecting a return loss greater than a return loss threshold.
