Tri-bimaximal mixing is a good approximation for the present data of neutrino mixing angles. The deviation from tri-bimaximal mixing is discussed numerically in the framework of the A_4 model. Values of tan^2θ_<12>, sin^22θ_<23> and |U_<e3>| deviate from tri-bimaximal mixing due to the corrections of the vacuum alignment of flavon fields. It is noted that sin^22θ_<23> deviates negligibly from 1 while sin^2θ_<12> can deviate from 1/3 considerably and sinθ_<13> can be near the present experimental upper bound. The CP violating measure J_<CP> and the effective Majorana neutrino mass <m_<ee>> are also discussed.
