If you’re not having issues I wouldn’t worry, you seemed to have dealt with this very well but there are a few more things I might check for the future. 1) check if you still have Apple Care 2) Take it to the Genius Bar at your local Apple Store and ask if they can check it out (they’ll usually check it out for you pro bono) 3) If they find any damage check if it would be cheaper to buy out your contract rather than repairing or replacing it (sometimes this is the case!) 4) Maybe purchase something like an OtterBox that seals your phone from moisture (for the most part) b/c personally I’d rather spend some money on a case rn then a new phone in the future if this happens again But again if nothing is evidently broken I wouldn’t worry :)
Okay so I also dropped my phone in water and this fixed it so use this 1) check all ports to make sure they are working (plug in headphones, use charger, try to play sound without headphones, etc.) 2) put phone in rice if headphone jack or charging port aren’t working, check periodically every 20 mins. If sound isn’t working, just use headphones for the rest of the day and let it charge overnight. 3) You’re done! Everything should be working normally by the time you wake up tomorrow morning! (Tip: if there is rice stuck in headphone jack, power phone off and use an earring, it works like a charm!)
