  We examined the possibility of recovering the losses of entanglement and the
non-local advantage by using the local symmetric operations. The improvement
efficiency may be increased by applying the symmetric operations on both
qubits.
  The recovering process of both phenomenon is exhibited clearly when only one
qubit is accelerated and the symmetric operations is applied on both qubits. It
is shown that, for large acceleration, the non-local coherent advantage may be
re-birthed by using these symmetric operations.
