As usual only the benefits of smartphones and similar devices seem to have been taken into account, e.g. they can be used to navigate around the ship and locate other personnel, and they are essential for recruitment and retention - the current generation won't serve with out constant connectivity with their loved ones.

No, sir.
Remove it, if I see it again when you are on watch
it'll get a float test.
Personally, I think today's generation is just like mine in wanting to push the boundaries, however given a good rationale they will obey the rules.
