A modular A4 flavor model with universal couplings reproduces charged lepton masses via the modulus tau and predicts correlated neutrino observables for normal mass ordering and right-handed weight k_N = -1.
In this case, the number of the independent phases reduced to three, i.e.M ν =M ν(τ, α, β, ϕ, kN)
