Abstract	We present measurements of the rare radiative decay B → K∗(892)γ using 365 fb−1 of data collected from 2019 to 2022 by the Belle II experiment at the SuperKEKB asymmetric-energy e+e− collider. Key measurements include branching fractions, CP and isospin asymmetries for B → K∗(892)γ decays. Additionally, we discuss the improvement in electron identification performance of the silicon-strip vertex detector of Belle II.
