  We propose to understand the mixing angles and CP-violating phases from the
$\Delta(48)$ family symmetry combined with the generalized CP symmetry. A
model-independent analysis is performed by scanning all the possible symmetry
breaking chains. We find a new mixing pattern with only one free parameter,
excellent agreement with the observed mixing angles can be achieved and all the
CP-violating phases are predicted to take nontrivial values. This mixing
pattern is testable in the near future neutrino oscillation and neutrinoless
double-beta decay experiments. Finally, a flavor model is constructed to
realize this mixing pattern.
