  We present a full phenomenological and analytical study for the neutrino mass
matrix characterized by two vanishing $2\times2$ subtraces. We update one past
result in light of the recent experimental data. Out of the fifteen possible
textures, we find seven cases can accommodate the experimental data instead of
eight ones in the past study. We also introduce few symmetry realizations for
viable and nonviable textures based on non-abelian ($A_4$ or $S_4$) flavor
symmetry within type II seesaw scenario.
