I pressure wash fir a living. My S7s lasted me many years but I still put them in a ziploc bag just to be safe. I buy the ones just big enough fir them then I put a viva towel in the bag with it to soak up any moisture so don't have to contend with vapor on the screen. A bag will lay a couple to 4 days but it's so cheap. I grey a new bag every day.
Then I use a water resistant bluetooth headset to answer calls.
Those waterproof bags are just $5 at 5 Beliw Store and often a beefier better bag at walmarts fir just$10. You may have to check several walmarts or order online.
Walmart had a good $90 bluetooth head set that lay me at least 3 months while being used everyday 6 days a week pressure washing. They have survive the accidental jumping in the pool too. Although I do recommend taking them off first.
