Just downloaded Go Launcher for the first time and still learning how to use it. One issue I'm having is when I press the physical key at the bottom, it asks if which program I want to use - Go Launcher or Touchwiz. I'm not 100% sure I'm keeping Go Launcher so I don't want to set it as the default program for this action. Does anyone know where you would undo this program default if I make the change? I've looked around all the settings and cannot find a place where you can change the default action of pressing the physical key.
