The "no jack" scandal (talk about your First World problems)

Funny to read this wanky, typically Apple, explanation noted at Slate about why the new iPhone has no ear phone jack:

Apple’s own explanation for the change was a little baffling. Schiller said the rationale for jettisoning the headphone jack could be summed up in one word: “courage.” What kind of courage? “The courage to move on, and to try something new that betters all of us,” he elaborated. OK then!

Further down, it is said that there is something the phone gets from not having one:

Well, for one thing, you can now drop your iPhone in the toilet. I mean, you could do that before, but now when you get it back out, there’s a decent chance it will continue to function. Eliminating the headphone jack enabled Apple to seal the phone at last, making it “dust and water resistant,” albeit not fully waterproof.

But wait a minute - the Samsung Note 7 (yes, I know - it can explode) has been heavily promoted as being waterproof to a similar degree, and it has an audio jack.

Why is Apple not able to use a similar water resistant jack?

I'm still sticking to my Samsung allegiance - even though my first experience with their cheap, early Tab 2 tablet was not great.  (Known bugs that were never fixed with any update.)  It's been made up for by my very, very pleasing Tab S, and a cheapo phone that is still pretty damn reliable.  I always have liked the look of the round edged Galaxy 7, too, but I'm not willing to spend that much on a phone.
