 The scotogenic model is well known for accommodating small neutrino mass and dark matter. Here, we have realized the scotogenic model with the help of discrete flavor symmetry A4 Z4. We have obtained three one zero textures of Yukawa coupling matrices from the model and have studied its impact on neutrino phenomenology and related aspects of cosmology. On the basis of μ-τ symmetry, we have further discarded two structures of one zero texture Yukawa coupling matrix. We further analyze if the effective mass of active neutrinos obtained by the virtue of the Yukawa coupling matrix is consistent with the KamLAND-Zen limit for 0νββ. Also different lepton flavor violating (LFV) processes such as lα → lβγ and lα → 3lβ are implemented and their influence on neutrino phenomenology is studied corresponding to the Yukawa coupling matrix. The entire work is carried out considering the dark matter mass (MDM) in the region 450-750 GeV. We have also obtained some significant results for baryon asymmetry of the Universe in agreement with the one zero texture of the coupling matrices. Furthermore, interesting results for relic abundance on the basis of distinct mass splittings are between the inert scalars. © 2022 World Scientific Publishing Company.
