The LHCb experiment has been reporting remarkable $C\!P$-violation (CPV) measurements concerning the sectors of $b$ and $c$ quarks. Recently, the new measurements of time-integrated CPV with $D^0\to K^+ K^-$ decays led to the first evidence ($3.8\sigma$) of CPV in a single charmed decay. The first search for CPV in the $D_{ (s)}^+\to K^+K^+K^-$ decays was executed. The knowledge of the CKM parameter $\gamma$ was improved by new results; the current combination of the LHCb measurements is: $\left(63.8^{ +3.5}_{ -3.7}\right)^\circ$. The study of $B_s^0\to\phi\phi$ decays resulted in the most precise measurement of time-dependent CPV in any penguin-dominated $B$ meson decay. All the results are consistent with the Standard-Model predictions.
