Duh, I'm getting old, I forgot all about those issues with the original production models and some instances where the water-resistance was compromised. Now I have to wonder how mine might handle that if it ever gets dunked (not that it will anytime soon since I do live in a desert). I had the GS4 Active myself, then the GS5A, the GS6A, and now this one and I have no issues with it whatsoever. The battery life for me is crazy, much better than I expected even with the 4000 mAh cell in it.
Hopefully these devices don't have any defects that might crop up as time passes, whether it's with the battery or anything else.
