Landscape form on iPhone 7
Recently I got a hand-me-down iPhone 7. I’d like to know how to watch a movie or something on iPhone in landscape form. Also how do I turn the phone back to portrait form?

Just rotate it.
If the screen doesn't rotate when you start a movie, access the Control Center by swiping up from the bottom of the screen and make sure the Lock button is unchecked.
