I LOVE lightflow and have been use it for a few years now. Unfortunately it barely works at the moment. Colors are different than what u select, ring tone plays for literally 1-2 seconds. He said he is trying to work on a workaround. He also setup something to help. It wasn't very success on my phone. So I'm hoping very soon he can figure something out. He said Samsung changed the way it is setup and there really is no rhyme or reason for the way the did.
