  Status of the discrete symmetry approach to explanation of the lepton masses
and mixing is summarized in view of recent experimental results, in particular,
establishing relatively large 1-3 mixing. The lepton mixing can originate from
breaking of discrete flavor symmetry $G_f$ to different residual symmetries
$G_{\ell}$ and $G_\nu$ in the charged lepton and neutrino sectors. In this
framework the {\it symmetry group condition} has been derived which allows to
get relations between the lepton mixing elements immediately without explicit
model building. The condition has been applied to different residual neutrino
symmetries $G_\nu$. For generic (mass independent) $G_\nu = {\bf Z}_2$ the
condition leads to two relations between the mixing parameters and fixes one
column of the mixing matrix. In the case of $G_\nu = {\bf Z}_2 \times {\bf
Z}_2$ the condition fixes the mixing matrix completely. The non-generic (mass
spectrum dependent) $G_\nu$ lead to relations which include mixing angles,
neutrino masses and Majorana phases. The symmetries $G_{\ell}$, $G_\nu$, $G_f$
are identified which lead to the experimentally observed values of the mixing
angles and allow to predict the CP phase.
