When authoring a mobile page, the page is displayed in a way that emulates the mobile device. When authoring the page, you can switch between several emulators to see what the end-user sees when accessing the page.
Devices are grouped into the categories feature, smart, and touch according to the capabilities of the devices to render a page. When the end-user accesses a mobile page, AEM detects the device and sends the representation that corresponds to its device group.
Use the following procedure to author a mobile page:
From global navigation open the Sites console.
Open the page We.Retail -> United States -> English.
Switch to Preview mode.
Switch to the desired emulator by clicking the device icon at the top of the page.
Drag and drop components from the component browser to the page.

The emulators are disabled when a page on the author instance is requested from a mobile device.
