Have my second handset in two days and neither of them properly work with my bluetooth hands free device. It works fine until the phone goes to sleep and then some functions work, but will not launch the voice command function on the phone. It's amazing to me that bluetooth has been around since the mid 90's and these genius, tech geeks still can't design this junk to work correctly. My four year old phone worked flawlessly with my hands free. It's a shame, I liked the phone otherwise.
