Honestly I've been waiting for a post like this! Let's just back track a bit. Late last year when I first obtained my Note 4, I decided to go through and read my whole manual. Well surprise surprise on page 22 (check your manual out) there is information on how the Note 4 is water-resistant and "meets requirements of classification IP67". Well I brought it to these forums and of course everyone shunned me down saying that its impossible because of the micro usb slot and s pen slot (because somehow even though its possible to make an audio jack waterproof its not possible to do the same to the other ports). I then decided to search for people like TechRax who torture test devices and tried to see if they were willing to submerge a note 4 in water, but of course no one was willing to do it. I guess your experience was the closest id hear of a waterproof test! But I'm still keeping my fingers crossed that someone else will do a proper test in the near future.
