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.
Touch and hold an empty area of a Home screen.
Tap Widgets & Apps (located in the lower-left).
Tap a widget.
For the widget to be successfully added, there must be sufficient space within the selected screen.
If applicable, tap additional options to activate widget.
Options may vary depending upon widget type.
