Widgets are mini-apps (e.g., weather, clock, calendar, etc.) that can be added to a Home screen. They aren't the same as shortcuts as they generally display info and take up more space than a single icon.
From a hHme screen, tap Apps (located at the bottom).
From the WIDGETS tab, touch and hold a widget.
Drag the widget to the preferred Home screen then release.
For the widget to be successfully added, there must be sufficient space within the selected screen.
If applicable, select additional options to activate widget.
Options may vary depending upon widget type.
