My niece found in Porto Rico an iPhoneX, near the beach, about 1m underwater. It worked, but screen was locked and no way to find who the owner was. We could get the SIM card. When they got back, my brother in law went to Verizon and told them to find who the owner was, and to call him. It was an Indian couple from New Jersey on their honey-moon vacation , and there were very happy to get their phone back, as they had all their honey moon pictures there. The estimate was that the phone was in water (about 1m of depth) for at least 3-4 days before my niece had found it. So, it was a good story, also that the iphoneX, when new, can survive in shallow waters. Overtime, the 'water proof' coating does smear out, and eventually give in. I wouldn't swim with one, especially if it is an older phone.
