Devices, methods, and graphical user interfaces for content navigation and manipulation

An electronic device, comprising:

• a display;
• a touch-sensitive surface;
• one or more sensors to detect intensities of contacts with the touch-sensitive surface;
• 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, content of a first content item, wherein the first content item is one of a sequence of content items;
• detecting a user input that includes movement of a contact in a respective direction on the touch-sensitive surface;
• and
• in response to detecting the user input:
• in accordance with a determination that the user input meets item-switching criteria, replacing display of the first content item with display of a second content item in the sequence of content items, wherein the item-switching criteria include a criterion that is met when a characteristic intensity of the contact is above a first intensity threshold;
• and,
• in accordance with a determination that the user input does not meet the item-switching criteria, navigating through the content of the first content item in accordance with the movement of the contact.
