Hi, I just found a new problem on my galaxy 551. When I connect my cell to any external speaker, either through Aux cable or directly to a speaker, sound comes only from the right speaker. I tried on various speaker systems and same problem occurred in all of them. But there is no such problem in the earphones, I am getting proper sound in both sides. Also there is no such setting in the cell phone to adjust right/left balance. So please help me with a solution!
