You can customize it.
Changing A Button
You don’t necessarily have to remove a button to replace it with a new one. You can edit a button so that it is replaced with a different one. To do so, tap the button you want to replace on the customization screen. A list of all supported functions will appear. Select which function you want to swap the old one out for and tap ‘Done’.
A Little Tip
As we mentioned earlier, most users become familiar with AssistiveTouch when their Home button stops working. They don’t really need any of the other buttons that appear when you tap the AssistiveTouch button. If you want the AssistiveTouch button to only execute the Home button’s function when you tap it, remove all other buttons from the menu as described above. Keep the Home button and when you tap the AssisitveTouch button, it will execute the Home button’s function without showing you a menu of other buttons.
