I've recovered my phone from the same issue. If you really want to know, i had to pull my phone apart and replace the battery since the water got all the way there. If you made the same mistake i did and keep turning it on, most likely you shorted the battery and maybe other parts. I suggest opening the phone and cleaning with isopropyl alcohol (disconnecting the battery and everything first!) any parts that you see have corrosion on it, although check whether you are covered by warranty first to save you the hassle (most places dont cover water damage.) I hope the best for you and you dont have as many issues as mine does now
