How do I change background an app screen after new update?

I don't want to change my lock screen - I want to change the home screen (where apps are) that has turned black!

Hi Jluis5639,

You can change the wallpaper on your Home Screen by following the steps outlined here:

"

Add a new wallpaper for your Lock Screen or Home Screen

1. In the Settings app, tap Wallpaper.
2. Tap Add New Wallpaper.
3. Tap Photos, People or Photo Shuffle to choose your own photo. You can also select a wallpaper from a category such as Weather & Astronomy, Emoji, Collections or Colour.
4. If you want, you can customise your wallpaper further. Then tap Add."

Change the wallpaper on your iPhone

We hope this helps out.

Cheers.
