In this paper, we attempt to implement the neutrino u-tau reflection symmetry (which predicts theta(23) = pi/4 and delta = +/-pi/2 as well as trivial Majorana phases) in the minimal seesaw (which enables us to fix the neutrino masses). For some direct (the preliminary experimental hints towards theta(23) not equal pi/4 and delta not equal -pi/2) and indirect (inclusion of the renormalization group equation effect and implementation of the leptogenesis mechanism) reasons, we particularly study the breakings of this symmetry and their phenomenological consequences.
