We present a minimal left-right symmetric flavor model and analyze the predictions for the neutrino sector. In this scenario, the Yukawa sector is shaped by the dihedral D 4 symmetry which leads to correlations for the neutrino mixing parameters. We end up with the four possible solutions within this model. We further analyzed the impact of the upcoming long-baseline neutrino oscillation experiment, DUNE. Due to its high sensitivity, it has been observed that the DUNE will be able to rule out

... o of the solutions. Finally, the predictions for the neutrinoless double beta decay and the lepton flavor violating process μ → eγ for the model have also been examined.
