  We revisit the $A_4$ model for leptons in light of new result of NuFIT 3.2.
We introduce a new flavon $\eta$ transforming as $A_4$ singlet $1'$ or $1"$
which couples to both charged leptons and neutrinos in next-leading order
operators. The model consists of the five parameters: the lightest neutrino
mass $m_1$, the vacuum expectation value of $\eta$ and three CP violating
phases after inputting the experimental values of $\Delta m_{\rm atm}^2$ and
$\Delta m_{\rm sol}^2$. The model with the $1"$ singlet flavon gives the
prediction of $\sin^2 \theta_{12}$ around the best fit of NuFIT 3.2 while
keeping near the maximal mixing of $\theta_{23}$. Inputting the experimental
mixing angles with the $1\,\sigma$ error-bar, the Dirac CP violating phase is
clearly predicted to be $|\delta_\text{CP}|=50^\circ- 120^\circ$, which will be
tested by the precise observed value in the future. In order to get the best
fit value $\sin^2\theta_{23}=0.538$, the sum of three neutrino masses is
predicted to be larger than $90\,$meV. The cosmological observation for the sum
of neutrino masses will also provide a crucial test of our predictions. It is
remarked that the model is consistent with the experimental data only for the
normal hierarchy of neutrino masses.
