You may be lucky but typically, the water is inside the phone, on the logic board and under the shields, even under the IC's. The real problem is the corrosion that is taking place as the water evaporates. Powering on the phone accelerates the process. The longer you let a phone stay wet, the more time you are giving corrosion to damage your logic board. The saltier or harder the water is, the more damage will occur.

Your phone may "work" now but it will likely fail in the near future.

You should do the following asap:

  • Open your phone and remove the logic board
  • Inspect the logic board, especially around the connectors and look for corrosion.
  • Inspect both sides of the board. Unfortunately, 80% of the board is covered in shields. That's usually where the damage is occurring.
  • Put your board in a container with >90% isopropyl alcohol and let it sit for a while.
  • Use a soft brush, like a toothbrush and lightly brush away any corrosion you see.
  • Rinse in alcohol and repeat.
  • Let it air dry for a day.
  • Re-assemble and hope for the best.

A professional repair shop that does water damage repair can decontaminate your phone because they have access to pro-level ultrasonic baths and specialized cleaners as well as the skills to troubleshoot your board if any problems pop up.
