We found this to be an interesting feature on the iphone. We quite often keep our clients informed of how their campaign is going via short videos that can be recorded and edited on an iphone. Below are the steps on how to activate screen recording. You may be able to use this to aid employees in your day to day.
Go to Settings > Control Center > Customize Controls, then tap the green + logo next to Screen Recording:
Swipe up from the bottom edge of any screen. On iPhone X or later or iPad with iOS 12 or later, swipe down from the upper-right corner of the screen.
Press deeply the grey circle and tap Microphone.
Tap Start Recording, then wait for the three-second countdown.
Open Control Center and tap the red record circle or tap the red status bar at the top of your screen and tap Stop.
Go to the Photos app and select your screen recording. You can then use an app like Lumafusion to edit the content and then message or email the video.
