What if the weather icon on the desktop doesn't show the weather forecast?

The weather icon is just the icon of this application.

To display the weather forecast, you need to add a desktop widget.

1) Press and hold the screen for a few seconds on the phone standby page, and click "Applications and Gadgets" when a dialog box appears. (as shown in the figure below)

2) Click "Widget" to find the component of weather forecast. Click it and put it on the desktop, so that the weather forecast can be displayed on the desktop. We don't need to turn on the weather forecast software every time we check the weather. (as shown in the figure below)
