Discovered last night that Note 3 has the capability through S Voice of wakening when you command "Hi Galaxy."
Further, if you install S for Switch Voice (DANA Logix) from the Playstore you will automatically bypass S Voice and connect to Google Now and have full use of that service and it's numerous commands.
All this without the Moto X or KitKat.
When it works, it works flawlessly. Problem I'm having is that when I say "Hi Galaxy" it activates about 10% of the time.
Any suggestions appreciated.
(If you install the S for Switch Voice app follow the instructions exactly or you will have to reinstall.)
