LOL. How many years behind Samsung has Apple been certifying IP68 phones?
How often do you go swimming with your Samsung phone?
Apple started providing 30 minute/1 meter IP67 water resistant phones in September 2016. They were dust resistant long before that.
A few of Samsungs phones claimed a 30 minute/1.5 meter plus IP68 rating starting in that same year, but testing labs found in testing multiple models of the same phone results of water leakage was iffy at less than 1.5 meters, leading them to conclude they were really just IP67.
