Samsung Galaxy S4 Microphone icon mising?

[Cooper]

The microphone being on the keyboard depends on what keyboard layout the app's programmer has put in their app. If the icon isn't in the keyboard, it will most likely be on the right side of whatever box you are typing in. The button depends app-to-app. For example, my Facebook app has the key in the keyboard, yet Google Chrome has it in the search bar itself. Hope this helps!
