What can I do if the weather is gone in the small plug-in of Samsung mobile phone screen?

if the weather widget is lost, suggestions are as follows: 1. add the weather widget again. Operation: application-click the widget at the top of the screen (long press the blank space of the screen under the standby desktop-widget-find the widget)-long press the icon and drag it to the desktop. 2. If there is no weather icon in the widget interface, it is recommended to back up the data in the mobile phone (such as contacts, multimedia files, etc.) and restore the mobile phone to factory settings. 3. If it doesn't work, send the mobile phone to your nearest after-sales service center to help you check the machine. Note: The weather widget will be removed after upgrading some mobile phone systems.
