Can’t find my camera icon on my phone

Apps can be removed from the home screen without being deleted. Go to the App Library (swipe left past your last home screen). From there you can touch and hold an app and slide it left back to the home screen.

FYI: Camera cannot be deleted.

Start here => Find your apps in App Library on iPhone - Apple Support

If you cannot find the Camera app then make sure you do not have restriction set in Screen Time.

Settings > Screen Time > Content & Privacy Restrictions > Allowed Apps > Camera: ON

Note: Content & Privacy Restrictions must be enable to see and make changes.
