Who enforces no mobile phone use on plane

And here is the inconsistency... some airlines allow gate-to-gate IFE. An immediate command from the crew (such as 'brace') not using the address system will not interrupt IFE.

Such permitted IFE is generally that provided by the carrier.

IME, any PA use appears to pause the IFE immediately.

That's the issue. It will only interrupt the IFE if the aircraft's address system is used. If it is an unplanned emergency (for example OZ at SFO), the issuing of a brace command may be instantaneous, no time for the cabin crew to pick up the phone, push the button and issue a command which interrupts the IFE.

The conversation has moved from phones to IFE. It would be good to stay on topic or start a new thread.

Related. One of the supposed reasons why you cannot use mobiles is so that you are able to give your attention to the crew in the event of an emergency. But this is negated by gate-to-gate IFE.

The mechanism for the risk is that an intense radio transmission could induce a current in the wiring in the aircraft's systems.
Worst case scenario it would corrupt either the data being seen by the pilots or (much less likely) the commands being relayed back to the aircraft.
Even if such an incident occurred it would then take a further combination of factors for it to result in an actual problem - as Daver6 points out.

My understanding is that this is largely a historical risk from when cables were poorly shielded because no one anticipated passangers routinely carrying radio transmitters onboard.
Modern aircraft have wiring systems which are better shielded against this risk. But caution abounds and change is slow - and those are good things in the context of safety!

I don't make phone calls after the door is closed. I do generally switch my phone to flight mode.
However I did find it annoying when a flight attendant on an MH flight objected to me using my phone (in flight mode) to take a photo out the aircraft window.
Hopefully if the rules are uniformly updated to be consistent and realistic - flight mode once the doors are closed but okay to use in flight mode gate-to-gate - then compliance will be simpler.
In the meantime I continue to annoy my best friend by taking my DSLR on board for those photo opportunities.

As a pilot i have had interference with navigation aids from phone use onboard. The investigation could not determine the location of the cause but it was narrowed down to most probably a phone left on (not flight mode) after takeoff. The risk is real and remains so - it is not necessarily a historical risk.

All airlines have their own policies on these things (and subject to their own regulators). MH require all personal electronic devices to be switched off for takeoff/landing, not just in flight mode.
