Abstract We present recent measurements of hadronic B meson decays produced in electron-positron collisions at the Υ(4S) resonance collected between 2019 and 2022 with the Belle II detector. We show measurements of BD()KKS0 decays including the first observation of three modes. Furthermore, we report on new results to determine the quark-mixing parameter Φ3/γ, performed on a combination of Belle and Belle II data. Measurements of Bρρ and Bππ are presented which serve as input for the determination of Φ2/α. Finally, determinations of branching fractions and direct CP-violating asymmetries of BKπ modes are shown to perform a direct test of the standard-model via the Kπ isospin sum rule.
