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 the preferred Home screen, touch and hold an empty space.
Tap Add apps and widgets.
From the Dropdown menu (located on the left), ensure Widgets is selected then tap the preferred widget.
For an item to be successfully added, there must be sufficient space within the selected panel.
If applicable, tap additional options to activate the widget.
Options vary depending upon widget type.
