The Bling Jet can be used for answering and making phone calls. You can click the Confirmation button (middle button) on the bling jet to answer an incoming call and double click the Confirmation button to make an phone call for the last dialing-out number on your smart phone. The Bling Jet can be operated for light-turning signal, walkie-talkie, music playing (pause, song switch), and photo taking except for answering the phone call.
