Camera icon
How do I put the Camera icon on the dock on iPhone 12
iPhone 12, iOS 15
Question marked as
The iPhone dock can contain 4 icons. You can make room by moving one of the 4 icons to the home screen (or into a folder), than move the Camera icon to the dock.
Take a look at this support page too:--> Move apps and widgets on the Home Screen on iPhone
