Screen disappeard. What is it and how do I get it back?
If you've mistakenly removed the weather widget from your home screen, try putting it back, i.e., long-press the home screen and you should get an edit screen. Tap widgets, then tap the weather widget to add it back to your home screen.
The clock widget?
It's the whole square that is gone. Where you set a city for weather and such. What did I turn off?
That was it. Thanks. First "smartphone". Much to learn.
In case you need it, here's a link to the user manual.
