Not charging after I dropped the S7 edge in wet sand
We were taking pictures at the beach and i accidentally dropped my wife's S7 Edge in some wet sand. We rinsed it off in fresh water and let it dry as we always have even with my S8+ when i used it in salt water. Her S7 Edge started acting up a little bit with charging, it was on and off and would not stay charging. She thinks it may still have sand in the port but i cleaned it out thoroughly. Anyone know if this could be a permanent issue with the phone or do we just need to keep attempting to clean it out?
PS: Wireless charging does work
