All electronic devices should be shut off prior to boarding.
And for those passengers, who say they go bonkers when unable to look at their devices every 5 seconds, they should be given a sedative.

They should be given a train ticket..............
That’s not so easy these days. Bluetooth is everywhere, in places you would never suspect.
I discovered my electric razor even has it, and there is no way to shut it off.
My hearing aids are blutoothed.
I have an implanted cardiac monitor that is bluetoothed. If they want me to turn that off they will have to supply me with a scalpel.
