i own a galaxy 551 and wish to answer and initiate calls with a bluetooth headset. There is "no return" policy with headsets therefore i can not do trial and error. the store clerk told me he thinks that my phone does not support initiating calls so i called samsung. the first time the tech told me it does and the second time a different tech told me that the phone does not support bluetooth initiating calls. Does anyone have a headset that does work to initiate a call and if so what model is it?
