LHCb measurements on CPV in $B$ decays ($B\rightarrow 3h$, $\phi_s$, charmless $B$ decays)

The latest results on the $CP$ violation measurements in $B$ decays are reported. The measurement of the weak phase $\phi_s^{s\overline{s}}$ using the $B^0_s \to \phi\phi$ decay mode is performed on a dataset corresponding to an integrated luminosity of $5\,fb^{-1}$ collected in proton-proton collisions by the LHCb experiment. Results on the first ever measurement of the $CP$-violating phase $\phi_s^{d\overline{d}}$ using $B_s^0 \to (K^+\pi^-)(K^-\pi^+)$ channel, based on $3\,fb^{-1}$ of data, are summarised.
