Amazing water resistance. Dropped my S-10 in the ocean during high tide while kayaking near the shore. (we have very large tides up to 8 feet) and figured it was lost. Got a new S-20 but really wanted the pictures back that I hadn't backed up. Went back to the spot where I thought it was at low tide 1 week later and found it. Didn't hold much hope, but cleaned it up and put the micro sd card in the new phone and got all my pictures back. Put the phone on the wireless charger and it came back to life. Got all my contacts, more pics that were in internal storage and it's still working! In salt water for a week it exceeded my expectations and probably Samsung's. Don't they rate it at 3 feet for 30 min (and they probably mean fresh water)
