So took my S4 44mm Space Black on holiday last week (had this since the S4 was released) and wore it on several swimming workouts (which I have done hundreds of times before in previous years), but unfortunately, it finally died on me 
Got out the pool, did the whole eject water thing and ended the workout and then literally a few minutes later, the screen started spazzing around going in and out of menus and screens as if someone was touching the screen??!!
It would still respond to my touches at random moments but it continued spazzing for a good 10 minutes or so. At one point, it started to do a countdown and play a siren (very loudly!!!) as it tried to call the emergency services?!!!!
Anyway, to cut a long story short and after many unsuccessful attempts to reset it/clear it (hold both buttons etc, none of which worked), my watch and/or screen is dead.
When it gets connected to the charger, no signs of life can be seen other than the watch becoming hot at the back where the charger connects.
I'm guessing that after hundreds and hundreds of sweaty workouts (watch was always cleaned with a damp flannel) and pool/sea swims over the years (watch was rinsed after swimming), the innards have finally succumbed to water ingress.
I was holding out for this year's S8 however I can't now wait without a watch so ordered the S7 just the other day.
Just wanted to tell my story...!!
