Why doesn't lego show the weather on my phone?

There may be several reasons:

• The main thing is to understand, did you have a weather app? If so, you may have uninstalled it by mistake. You may need to download it again. For example one of the handy weather apps.
• If you have an application, but you had a widget on your desktop, you could have uninstalled it by accident as well. You just need to add the widget to your desktop again. And what are widgets and what are they for you can find out from here.
• Also, if both the application and the widget are in place and the weather is still not shown, you need to enable geolocation so that the application can automatically determine your location and receive data from the weather application server. You can read everything about geolocation here.

I hope that after that everything will work for you!

You have probably removed the weather widget. To install the widget, click on an empty spot on the screen, hold the touch and select "Widgets" from the menu that appears.

In addition, you can use any other weather widget. Go to Google Play, enter "Weather" in the search and select the one that suits you (for example, Yandex.Weather).
