To screen record on an iPhone 1 (which is assumed to mean the iPhone 11 or a similar model):
- First, add Screen Recording to the Control Center:
- Go to Settings > Control Center > Customize Controls.
- Tap the green plus (+) icon next to Screen Recording to add it.
- To start recording:
- On iPhone 11 and newer, swipe down from the upper-right corner of the screen to open the Control Center.
- Tap the Screen Recording button (a circle with a dot inside).
- There will be a 3-second countdown, then the recording starts.
- To record with audio, press and hold the Screen Recording button, then tap the microphone icon to turn on audio recording before starting.
- To stop recording:
- Tap the red status bar or the red circle in the Control Center and confirm to stop.
- The screen recording is saved automatically to the Photos app.
This process works on iPhones running iOS 11 or later and is built into the system without needing any third-party app.
