The samsung s5 seems to be a weaker phone in comparison to the HTC M8. The only thing better is the water resistant feature. However, a case that is water resistant for the m8 would work just as well. So now I am wondering if sprint has such a case?
it actually is water resistant, but not rated for it and definitely not water proof. I've watched videos of the HTC ONE M8 completely submerged for 30 minutes and it comes out fine. but wouldn't be trying this just to prove the point.
I saw that video too.. The phone apparently does very well in water, but since it does have the USB and headphone jack port covers it's not rated.
