Ok If you are talking about the location setting on your weather app then i tell you that at first go to the weather button and launch app
- On the lower right hand side you will see a white "i"
- Click on that "i" and you will go to another screen with a "+"
- Type in the city, state or zip
- When you find the correct city, select it and hit "done"! And you can also click on the + button at the top of the screen to look up another location and add it to the list.
