We perform a model-independent analysis of the possible residual Klein and generalized UP symmetries associated with arbitrary lepton mixing angles in the case that there are three light Majorana neutrino species. This approach emphasizes the unique role of the Majorana phases and provides a useful framework in which to discuss the origin of the Dirac UP phase in scenarios with spontaneously broken flavor and generalized UP symmetries. The method is shown to reproduce known examples in the literature based on tribimaximal and bitrimaximal mixing patterns, and is used to investigate these issues for the case of a particular (GRA) golden ratio mixing pattern.
