A key selling point for Samsung last year was water-resistance, and now all manufacturers are doing the same. And if they don't many dock points for a phone missing this feature.
The Galaxy S8 and S8+ are again IP68 dust and water resistant. Meaning they can get wet and be fine. Not to mention be submerged under around 5ft of water for over 30 minutes and work perfect. We've tested this too. You'll absolutely love the peace of mind it brings.
As a comparison, the iPhone 7 is only IP67 rated. So it can't go as deep or as wet for very long, or it could still fail. So Samsung leads the pack in this regard. Water resistance isn't a must-have for me, but being able to use my phone without worry is extremely satisfying.
