How to record the screen on iPhone
This How to is more than 2 years old and may be outdated.
Screen recording can be a very useful feature for iPhone users (iOS 11 and newer). Now you can record your screen with or without background sound on your iPhones, iPads or iPod touch.

Step 3
Start Screen Recording
Exit Settings and swipe up on your older iPhones or if you own iPhone X and iOS 12 or newer, swipe down from the upper right part of the screen.
Tap and if you want the sound to be on, tap Microphone. You can record without sound as well.
Screen recording will start after 3-second count down so you have enough time to prepare the screen you wish to record.
