Oh the brits!
It is a RULE, therefore do it.
Kinda like standing in a queue.
Actually this discussion was about the reasons / need for the "rules". Rather than questioning if there was a rule. the original poster was concerned about the safety risk.
The point about India et al, was simply to indicate that this request is frequently disregarded, either deliberately or accidentally, and i daresay it is as commonly transgressed everywhere - without any apparent impingement on safety.
suggest you have a poke at the cabin crew forum here on pprune (can't post the link, the tablet makes that a huge chore and the pax on my left is glaring at me
) discussing the use of a GoPro in the cockpit. GoPros (can) use GPS.
