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 Home screen, press and hold a blank area of the screen.
Tap Add apps and widgets.
From the Dropdown menu (located toward the left), ensure Widgets is selected.
Drag a widget to the preferred Home screen location then release.
For the widget to be successfully added, there must be sufficient space on the selected screen.
If applicable, configure any additional options to activate widget.
Options vary depending upon the type of widget.
