My Samsung Galaxy S7 can (theoretically) be in up to 5' of water for up to 30 minutes with no issues. Haven't dropped it in the lake, but it went in the livewell once with no issues (and YES, Bill.....there WAS water (and fish!) in it at the time!!!) and have spilled stuff on it countless times. iPhones were a bit behind the curve on that up until the X (or maybe the one before that??)
