Recently purchased a Samsung Galaxy S7 with android. I have been trying to get the phone to make calls for me while I'm driving from my bluetooth ear piece. I can receive calls while driving along but, cannot wake up Google or, the S voice. If I touch it or, turn it on the Google voice will become activated but, I need it to be totally touchless/hands free. Anyone else have this problem and have found a solution? My old flip phone had this ability. What happened to the "smart" in this one.
