The present disclosure relates to device configuration user interfaces. A first electronic device with a first touch-sensitive display is in a paired relationship with a remote second electronic device with a second display. The first device displays a user interface that includes one or more representations of locations on the second display. The first device detects a user input on the first display at a representation of a first location on the second display, where the representation of the first location includes an affordance. The first device detects movement of the user input from the representation of the first location to a representation of a second location on the second display. In response to detecting the movement of the user input from the representation of the first location to the representation of the second location, the first device associates the affordance with the second location on the second display.
