We perform an amplitude analysis of B+- -> phi(1020) K*(892)+- decay with asample of about 384 million BBbar pairs recorded with the BABAR detector.Overall, twelve parameters are measured, including the fractions oflongitudinal f_L and parity-odd transverse f_perp amplitudes, branchingfraction, strong phases, and six parameters sensitive to CP-violation. We usethe dependence on the Kpi invariant mass of the interference between the JP=1-and 0+ Kpi components to resolve the discrete ambiguity in the determination ofthe strong and weak phases. Our measurements of f_L=0.49+-0.05+-0.03,f_perp=0.21+-0.05+-0.02, and the strong phases point to the presence of asubstantial helicity-plus amplitude from a presently unknown source.
