Device, Method, and Graphical User Interface for Establishing an Impromptu Network

An electronic device with a touch-sensitive surface and a device motion sensor detects a predefined gesture on the touch-sensitive surface. The predefined gesture has one or more gesture components. The device detects a predefined movement of the electronic device with the device motion sensor. The predefined movement has one or more movement components. In response to detecting the predefined gesture and the predefined movement, the device, in accordance with a determination that the one or more gesture components and the one or more movement components satisfy predefined concurrency criteria, performs a predefined operation that is associated with concurrent detection of the predefined gesture and the predefined movement, and in accordance with a determination that the one or more gesture components and the one or more movement components do not satisfy the predefined concurrency criteria, foregoes performing the predefined operation.
