How to delete home-screen icons? Most don't have "deletion X" when jiggling
How does one delete unwanted icons from the home screen?
I know how to press and hold an icon so that they all start jiggling, allowing one to rearrange them -- and supposedly to delete unwanted ones. However, when I do that, only one of the icons has a little "X" in its upper left corner which is the thing which when pressed deletes the icon. And that's not even among the icons I wanted deleted. The ones which I do want to delete don't have "X"s on them so I can't delete them.
What am I doing wrong? Is it simply impossible to delete certain icons? If so, why?
Keep in mind that I don't use my iPhone as a mini-computer -- I use it only as a phone -- so I've never actually downloaded or installed any "app" aside from the ones that came with the phone. It is some of these built-in apps which I want to delete -- specifically, "Weather," "Stocks," "YouTube," and "Maps."
(The one icon which does have a "deletion-X" is a bookmarked Safari page (Google, to be precise.) It's just about the only thing I've ever "added" to the home screen.)
This is not a big deal, obviously, I'm just getting tired of looking at all these icons which I've never used and never will use, and tried to delete them and was unable to.
Any help would be greatly appreciated.
