Disabling Samsung Voice Input So It Will Use Google Voice Input Instead
Swipe down on your phone. Hit the settings icon in the top right corner (a gear). Hit the search icon (a magnifying glass). Type in voice and scroll to nearly the bottom and hit "App Info - Samsung Voice Input". Then when the app info comes up, in the bottom left corner is "disable", click that and it will turn off the Samsung Voice Input everywhere and leave you with the much better Google Voice Input.
