Troubleshooting Lost Home Screen Apps:
Two methods...
A. Drag it Back:
Swipe your finger in from the right. Then, drag it back over.
No Success?...
B. Reset the Home Screen Layout:
If a widget or app has gone mossing somehow, then you need to reset the Home Screen Layout...
Go Here: Move and organize apps on iPhone - Apple Support. You'd have to add back all the widgets that you can recall being back on there; so, take a screenshot of each Home Screen, so you can add apps back to where there should be.
Scroll to: Reset the Home Screen and Apps to their Original Layout
- Go to: Settings
- Tap: General
- Tap: Reset
- Tap: Reset Home Screen Layout
- Then... Add the apps back
