So 2 days ago, I dropped my phone in the pool and the home button stopped working. I never received the notification that says it needs to be repaired. My fingerprint doesn’t work either. I have tried powering it off and letting it die, but it still doesn’t work. What is wrong with my phone and how do I fix it without going to the store to get it fixed?
Water has most likely begun corroding components. Your homebutton sensor and the pins are the first to fail with moisture. Best option is to either reach out to Apple, or replace it and see if it works. Use 99.5% isopropyl alcohol to carefully clean any corrosion from the pins, remember replacing your homebutton will remove your touch ID functionality.
