Just upgraded from HTC Thunderbolt to DNA. DNA faster but they cut some functions or I have not found out how to use them. On my old HTC Thunderbolt I could touch the microphone icon and use the voice command to call anyone in my contact list. It does not work on my new HTC DNA. This feature kept me from having wrecks while driving because all I had to do was punch one icon then speak “call so and so cell” and the call would be made. How do I turn it on or get it to work?
