  We recently proposed a spontaneous A$_{4}$ flavor symmetry breaking scheme
implemented in a warped extra dimensional setup to explain the observed pattern
of quark and lepton masses and mixings. The main features of this choice are
the explanation of fermion mass hierarchies by wave function overlaps, the
emergence of tribimaximal (TBM) neutrino mixing and zero quark mixing at the
leading order and the absence of tree-level gauge mediated flavor violation.
Quark mixing and deviations from TBM neutrino mixing are induced by the
presence of bulk A$_4$ flavons, which allow for "cross-brane" interactions and
a "cross-talk" between the quark and neutrino sectors. In this work, we study
the constraints associated with the recent measurements of $\theta_{13}\approx
9^\circ$ by RENO and Daya Bay, forcing every model that predicts TBM neutrino
mixing to account for the significant deviation of $\theta_{13}$ from 0, while
keeping the values of $\theta_{12}$ and $\theta_{23}$ close to their central
experimental values. We then proceed to study in detail the RS-A$_4$
contributions to $\mu\to e,3e$, generated at the tree level by virtue of
anomalous $Z$ couplings. These couplings arise from gauge and fermionic KK
mixing effects after electroweak symmetry breaking. Since the experimental
sensitivity for $BR(\mu\to e,3e)$ is expected to increase by five orders of
magnitude within the next decade, it is shown that the RS-A$_4$ lepton sector
can be significantly constrained. Finally, we show that when "cross-brane"
interactions are turned off, the $Z$ couplings are protected against all
anomalous contributions and a strong correlation between $\theta_{13}$ and the
deviation from maximality of $\theta_{23}$ is found.
