I turned on my mobile phone desktop this morning, and there was no weather forecast.

You can try resetting the weather widget in the following ways:

1. Under the standby desktop, press and hold the screen blank -widget- Find Weather widget- and drag it to the home screen (Note: the way for the early listed machines to enter the widget: Apply-widget-You can view the contents of the widget).

2. Add a city: click the weather widget on the home page, click "+"on the page that appears to search and add a city.
