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 any open space (where no shortcuts or widgets are present).
En la pestaña Widgets, selecciona un widget.
The widget will be placed on the selected Home screen. To move the widget, touch and hold then drag to the preferred location.
