Here's what I do regarding recording the screen during flight to have a video record of everything that happens - I use the following checklist:
Tony
- review amount of free space on phone and free up space if needed (you can do a test screen recording using a simulation to check for size and practice)
- if you going to be in an area with bad cell reception that is hard on the battery, have a battery booster (like at BALLS)
- at the field make sure compass is calibrated (look for online instructions if not sure how to do this)
- make sure the Screen Recording button is added to control center
- go to Display and Brightness and set Auto-Lock to Never (prevents screen from going to sleep during recording)
- set a reminder for that evening to reset auto-lock
- make sure Mute is off and volume is turned up, optionally turn on Do Not Disturb
- if you want to record both App audio and Microphone audio, long press on the screen recoding button and tap the Microphone On button (in addition to capturing the countdown, I use this to make audio notes during the flight)
- put several post it notes around my prep area reminding me to turn on screen recording!
