Chosen Solution

I left my phone in my bathing suit pocket white I went to the beach. It was in there for about a minute or 2 in shallow waters before I realized and immediately left the water to dry it. The phone operated fine after taking it out turning on and being able to open it and use it. The only problems were the Face ID wouldn’t work and it didn’t recognize the SIM card. I rinsed it off with fresh water and put away since I wasn’t able to leave. About 2 hours later I’m going to leave and I check on it. The touchscreen doesn’t respond at all and I can’t interact with it. I take it to the beach house, take out and put back in the SIM card, and rinse it off under the sink to no avail. The phone has connection again so the SIM card problem is fixed but the touchscreen still won’t work. I left it in the sun to dry for a few hours and came back to the touchscreen working again, but I was only able to unlock it before the touchscreen immediately become unresponsive again. Everything else on the phone is functional and I have reset 100 times already. I cannot go to any place to get it checked out for at least a week since the beach I’m at doesn’t have any place nearby. Is there any fix I can try? Should I keep it in the sun to see if the touchscreen suddenly starts working again? Am I stuck without a phone for a week on vacation with no solution realistic for my situation?

@jsavbank .. youre going to want to turn your phone off and never turn it back on until the damage has been dealt with. every second its on youre continuing to corrode your motherboard.
