N2 - Anisotropic flow fluctuations can be used to constrain the initial conditions and probe the properties and evolution of the system created in heavy-ion collisions. In this proceeding, the P-T-differential flow coefficient v(n) with 2-, 4-, 6- and 8-particle cumulants for charged hadrons are investigated, which allows to study the higher order moments, including skewness and kurtosis, of v(2) probability density function (p.d.f.). In addition, the v2 fluctuations of pi(+/-), K-+/-, p + (p) over bar, phi, K-s(0), A + (A) over bar and Xi(-) + Xi(=) are also measured at mid rapidity in Pb-Pb collisions at root S-NN = 5.02 TeV using multi-particle cumulants. The implications of the results for understanding the properties of the medium are discussed.
