Devices and methods for processing touch inputs based on their intensities

An electronic device displays, on a display, a user interface. While displaying the user interface, the device detects an input on the touch-sensitive surface; and, in response to detecting the input while displaying the first user interface, and while detecting the input, in accordance with a determination that the input satisfies first timing criteria and first intensity input criteria, performs a first operation. The first timing criteria require that the input remain on the touch-sensitive surface while a first time period elapses. The first intensity input criteria require that the input satisfy a first intensity threshold at an end of or subsequent to the first time period.
