I bought my bluetooth about a year ago and worked flawlessly with the LG En V Touch I had before. It does not work with my HTC Touch Pro 2 though. I called Samsung, and they could not tell me whether it was a compatibility issue with the phone or not. I have read this bluetooth is compatible with most smart phones, including mine. They may have been wrong, since the phone does not even recognize the bluetooth when it is searching for devices. The description here states that is compatible with other non-Sanmsung bluetooth enabled phones, but maybe mine is just not included on those. Maybe I should give HTC a call about this compatibility issue as well. It is a very good device though! I highly recommend it!
