Facebook icon keep disappearing from Home Screen on iPhone

Hello nilda195,

Welcome to Apple Support Communities. We understand that the Facebook app is no longer showing on the Home Screen. We are happy to help.

It sounds like the Facebook app may be in the App Library. Please use the steps here to check: Find your apps in App Library on iPhone - Apple Support

"Find and open an app in App Library

1. Go to the Home Screen, then swipe left past all your Home Screen pages to get to App Library.
2. Tap the search field at the top of the screen, then enter the name of the app you’re looking for. Or scroll up and down to browse the alphabetical list.
3. To open an app, tap it.

If a category has a few small app icons, you can tap them to expand the category and see all the apps in it.

Hide and show Home Screen pages

Because you can find all of your apps in App Library, you might not need as many Home Screen pages for apps. You can hide some Home Screen pages, which brings App Library closer to your first Home Screen page. (When you want to see the hidden pages again, you can show them.)

1. Touch and hold the Home Screen until the apps begin to jiggle.
2. Tap the dots at the bottom of the screen.
3. Thumbnail images of your Home Screen pages appear with checkmarks below them.
4. To hide pages, tap to remove the checkmarks.
5. To show hidden pages, tap to add the checkmarks.
6. Tap Done (on an iPhone with Face ID) or press the Home button (on other iPhone models).

With the extra Home Screen pages hidden, you can go from the first page of the Home Screen to App Library (and back) with only one or two swipes.

Note: When Home Screen pages are hidden, new apps you download from the App Store may be added to App Library instead of the Home Screen.

Move an app from App Library to the Home Screen

You can add an app in App Library to the Home Screen, unless it’s already there.

Touch and hold the app, then tap Add to Home Screen (available only if the app isn’t already on the Home Screen).

The app appears on the Home Screen and in App Library."

These steps may help. Please let us know if you have further questions.

Take care.
