Can someone tell me where to go to set my words for my voice command? Like smile or cheese?
You need to go to your settings/my device and go to voice control.
Yep. that should do it.
If it doesn't, try
S Voice > Menu Button > settings "S-Voice settings" > Voice cmd for apps
Ok that got me to the wake up command but I want to control the camera. I didn't see anything in there for that
Once you enabled voice commands for camera, go to your camera app, and under the settings, you should see the option to enable voice control (camera--settings--in the popup window, go to settings tab--scroll down--click on voice control - enable)
I re-read your op - I don't think you can change the words for the voice command, but you should be able to enable voice command for camera this way
