I accidentally deleted my clock/weather from my home screen on my Samsung Galaxy S3. I downloaded a new app but when I add it to my home screen it just stays small, when I tap on it it just gives me "important information" on how to add it. It is added, it just won't open! Help!
Go to the app drawer. At the top, you should see
Widgets, and scroll through the pages. Look for the weather widget.
Once you find the widget, long-press on it and drag it to your home screen.
EDIT #1: Here's an example. In this case, I am using the Accuweather app. AND, I'm not using the default launcher, but you should find something similar.
