The phenomenological consequences of the residual Z^s_2 and Zbar^s_2 symmetries are explored in detail. With a precisely measured value reactor angle, these two predict distinct distributions for Dirac CP phase atmospheric which leads to possibility identifying them at neutrino experiments. For both symmetries, it is possible resolve mass hierarchy most parameter space, they can be distinguished from one another if true symmetry angle non-maximal. These results obtained using an equally split schedule: 1.5-year run neutrinos antineutrinos NOvA together with 2.5-year T2K. This schedule significantly increase stabilize sensitivities octant only moderate compromise sensitivity distinguishing Zbar^s_2.
