please explain s7 edge water proof capability

s7 edge is first of all not water proof it is actually water resistant and it can remain in water for 30 minutes and I t can remain in water for a particular depth

means water will not damage it for a particular time

the s7 and s7 edge is water resistive phone and it is like 1.5 meter deep max and 30 minute max

My advice....If you dont need to put your phone in water...you will avoid Minor problems such as speakers and charging port...

the main Idea: if you dont need to..its better
