I've done extensive user testing with people on both Android and iOS devices (and, comparatively on Windows and MacOS devices) and the common thread that I see is that Android users coming to an iPhone try to use it exactly the same way that they use their Android device and then get frustrated that it doesn't work the same way. Windows users try to use a Mac exactly the same way they use Windows and get frustrated when it doesn't work that way. Inversely, the same is try for iPhone users trying to use Android and Mac users trying to use Windows. They ignore the intuitive features of both sides simply because they're used to working with one or the other.

If you can't figure out how to do things on an iPhone and think it's difficult, I'd wager a argument that it's because you're not just looking at what's there, you're trying to project your existing experience onto a different device and expecting it to work the same way. In other words (and I don't really say this sarcastically), you're using it wrong. If they were meant to be used the same way, they'd be the same products and they're not.
