Devices, methods, and graphical user interfaces for providing feedback during interaction with an intensity-sensitive button

An electronic device, comprising:

• a display;
• a touch-sensitive surface;
• one or more sensors to detect intensities of contacts with a button of the electronic device;
• one or more processors;
• memory;
• and
• one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions for:
• displaying, on the display, a first user interface;
• while displaying the first user interface, detecting an input directed to the first user interface;
• in response to detecting the input directed to the first user interface:
• ceasing to display the first user interface, and
• displaying a second user interface, distinct from the first user interface;
• while displaying the second user interface, detecting a contact on the button;
• while continuously detecting the contact on the button:
• detecting an increase in a characteristic intensity of the contact above a first intensity threshold;
• in response to detecting the increase in the characteristic intensity of the contact to the first intensity threshold, displaying a beginning of a transition from the second user interface back to the first user interface;
• while displaying the beginning of the transition from the second user interface back to the first user interface, detecting an input sequence that includes detecting a press input that includes an increase in the characteristic intensity of the contact above the first intensity threshold;
• in response to detecting the input sequence:
• in accordance with a determination that the input sequence meets first criteria, wherein the first criteria require that the characteristic intensity of the contact increases above a second intensity threshold before an end of the press input is detected:
• ceasing to display the second user interface, and
• redisplaying the first user interface on the display;
• and
• in accordance with a determination that the input sequence meets second criteria, wherein the second criteria require that the characteristic intensity of the contact remains below the second intensity threshold before the end of the press input is detected:
• reversing the beginning of the transition from the second user interface back to the first user interface, and
• redisplaying the second user interface on the display.

A non-transitory computer-readable storage medium storing one or more programs, the one or more programs comprising instructions that, when executed by an electronic device with a display, a touch-sensitive surface, and one or more sensors to detect intensities of contacts with a button of the electronic device, cause the electronic device to:

• display, on the display, a first user interface;
• while displaying the first user interface, detect an input directed to the first user interface;
• in response to detecting the input directed to the first user interface:
• cease to display the first user interface, and
• display a second user interface, distinct from the first user interface;
• while displaying the second user interface, detect a contact on the button;
• while continuously detecting the contact on the button:
• detect an increase in a characteristic intensity of the contact above a first intensity threshold;
• in response to detecting the increase in the characteristic intensity of the contact to the first intensity threshold, display a beginning of a transition from the second user interface back to the first user interface;
• while displaying the beginning of the transition from the second user interface back to the first user interface, detect an input sequence that includes detecting a press input that includes an increase in the characteristic intensity of the contact above the first intensity threshold;
• in response to detecting the input sequence:
• in accordance with a determination that the input sequence meets first criteria, wherein the first criteria require that the characteristic intensity of the contact increases above a second intensity threshold before an end of the press input is detected:
• cease to display the second user interface, and
• redisplay the first user interface on the display;
• and
• in accordance with a determination that the input sequence meets second criteria, wherein the second criteria require that the characteristic intensity of the contact remains below the second intensity threshold before the end of the press input is detected:
• reverse the beginning of the transition from the second user interface back to the first user interface, and
• redisplay the second user interface on the display.
