Abstract	We report the measurements of $\CP$ asymmetry and branching fraction of various charmless $B$ decays performed using $\epem$ collision data recorded at the $\FourS$ resonance with the Belle II detector at the SuperKEKB collider. These include a test of the standard model using isospin sum rule, an investigation of localized $\CP$ asymmetries in the Dalitz plot, and an expected improvement on the precision of the CKM unitarity angle $\phi_{2}/\alpha$. All the results agree with the previous determinations and contribute important information to an early assessment of Belle~II performance.
