Bluetooth V50 : Compatible new mobile phones

Hello to the forum, we have been proud owners of a V50 R design since mid-October and actually very satisfied. Only the Bluetooth hands-free system does not work as we imagined. The Samsung SGH F-480 of my wife is recognized, but breaks off the conversations. So we made ourselves on the Volvo side smart and found that there are suitable and less suitable mobile phones. The Samsung e.g. interrupts after a few seconds the connection to the hands-free device. The mobile phones, which are listed in the Volvo catalog but no longer correspond to the current delivery level. My wife was in the mobile phone store. There was determined due to the submitted Volvo list that there are either no more indicated mobile phones or these do not correspond with the specified Volvo tested firmware anymore because partly this firmware has already changed twice or more. Question now to you: Who has bought from you a new Volvo with appropriate hands-free device and which mobile phone works with you? First of all – then all mobile phone functions – like e.g. dial up by voice control? Because according to the Volvo list falls even with the phones that are offered as a top hand? Who uses these mobile phones?
