@christianjuresh There are usually liquid damage indicators (LDI) on phones, you can use this [link|https://www.samsung.com/us/support/troubleshooting/TSG01001077/|guide|new_window=true] to check if yours has been triggered.
However, note that excessive humidity can trigger the LDI as well, not necessarily just being dunked in water.
If the rest of your phone does not have corrosion damage, that is a way to argue that the phone has not been exposed to water since no other water has entered the phone.
