You might as well have smashed it with a hammer. See
Wet Phone. Letting a wet phone dry is almost certain death, even with the battery removed immediately.
About all you can do to "fix it" now is buy a new one. The cost of cleaning the case and replacing the parts is going to cost more than the retail price of 2 phones.
My standard mantra is that if your pants fall down and your phone falls into water at the same moment, pull the battery out of the phone before pulling your pants up (you have that short a time - and even that long, a second or two, can cause a lot of damage, depending on what's in the water - weak hydrochloric acid, what you have in a chlorinated pool, is deadly to electronics) - then get the phone immersed in alcohol and swish the phone around enough to force all the other stuff out of it as soon as physically possible. I've saved many phones that got wet but in over a decade I only managed to save one phone that was allowed to dry for a few days - and it only lasted a few months after that.
That's why warranties don't cover water damage - they have to replace the phone and reclaim the gold in yours. Your water-damaged phone is worth less than $10 at today's gold price. A couple of zip lock bags, if you're going to be near water, are a LOT cheaper. And make any phone virtually waterproof for at least a couple of minutes of immersion.
