  An angular analysis of the $B^{0}\rightarrow K^{*0}(\to
K^{+}\pi^{-})\mu^{+}\mu^{-}$ decay is presented using a data set corresponding
to an integrated luminosity of 4.7 fb$^{-1}$ of $pp$ collision data collected
with the LHCb experiment. The full set of $C\!P$-averaged observables are
determined in bins of the invariant mass squared of the dimuon system.
Contamination from decays with the $K^{+}\pi^{-}$ system in an S-wave
configuration is taken into account. The tension seen between the previous LHCb
results and the Standard Model predictions persists with the new data. The
precise value of the significance of this tension depends on the choice of
theory nuisance parameters.
