Samsung/Sprint released an update to the A900 phone today or yesterday (version ZB12) which directly addressed the “phantom ringing” issue that I, as well as others, reported. This is excellent as I can now use a Bluetooth headset with the phone. However, my Parrot EasyDrive carkit doesn’t work with it, yet. I’m not sure if this is a Parrot problem or a Samsung problem, but I suspect Samsung as I can use the carkit with a GSM phone I have on my desk.
I’m keeping my fingers crossed that Samsung/Sprint will iron out this remaining issue in the near future. It’s disappointing to see the fixes take so long and not to have them in there before the phone was released, but I’m glad they’re finally getting addressed.
