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, touch and hold a blank area.
From the Widgets tab, touch and hold a widget.
Drag the widget to the preferred Home screen then release.
There must be sufficient space on the screen to add the widget successfully.
If applicable, tap additional options to activate widget.
Options vary depending upon the type of widget.
