Here, we present a measurement of angular observables and a test of lepton flavor universality in the $B\to K^{*}{\ell }^{+}{\ell }^{-}$ decay, where $\ell$ is either $e$ or $\mu$ . The analysis is performed on a data sample corresponding to an integrated luminosity of $711{\mathrm{fb}}^{-1}$ containing $772\times 10^6$ $B\overline{B}$ pairs, collected at the $\mathrm{{\rm Y}}\left(4S\right)$ resonance with the Belle detector at the asymmetric-energy $e^{+}{e}^{-}$ collider KEKB. The finding is consistent with standard model (SM) expectations, where the largest discrepancy from a SM prediction is observed in the muon modes with a local significance of $2.6\sigma$ .
