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.

Never mind. Got it. Thanks for your help!

In case you need it, here's a link to the user manual. http://downloadcenter.samsung.com/content/UM/201404/20140402111855054/SM-G900F_UM_EU_Kitkat_Eng_D06_140312.pdf

Yes. I thought it was full. Again thanks. When the widget disappeared I thought I did something wrong. Know what apps are. Widgets are new term for me.

If you don't have enough room/space on the home page for the widget to fit, it will move to another home screen. If you make room on the home screen (by moving some apps/widgets to another screen), you should be able to long-press the widget and slide it to the other screen.** looks like you figured it out yourself as I was typing my reply; good deal !
