We present a summary of recent studies on CP violation with the Belle experiment using the final data sample of 772 × 10 6 BB pairs produced at the ϒ(4S) resonance at the KEK asymmetric e + e − collider. We discuss preliminary measurements of the branching fraction, the polarization and the CP asymmetries of the decay B 0 → ρ + ρ − and an updated constraint on the CKM angle φ 2 from the B → ρρ system. Being also related to φ 2 , we present a preliminary measurement of the branching fraction of
