We study the dynamics of geometric measure of quantum discord (GMQD) under
the influences of two local phase damping noises. Consider the two qubits
initially in arbitrary X states, we find the necessary and sufficient
conditions for which GMQD are unaffected for a finite period. It is further
shown that such results also hold for the non-Markovian dephasing process.
