The interference is really minimal and a ton of airlines still use paper preflight stuff anyways. I used to have to run a 10ft long dot matrix printout with computer codes to them when I worked at the airport 6 years ago. But that was dash-8s so not really the most up to date planes
I don't think they ask you to turn things off anymore. How recent is this?
They only ask you to not wear headphones unless they're connected to the on-board system now.
I've flown a few times in the past year and never heard that one. Then again I probably already had my headphones on when they said it
