Change iPhone home button functions

Did you know you can change the function of the home button on an iPhone?
By default triple-clicking the button will enable you to open a variety of functions, including toggling VoiceOver and a different colour scheme.
But you can change this. To do so, open the “Settings” app, and then click on “General”. At the bottom of the screen you’ll see the option for “Triple-Click Home”.
There, you can choose which function you want to the triple-click option to open, or you can set it so the iPhone asks you each time.
