Phone Type: LG Revel(?) 3G
Some backgrounds:
I was arriving near the fridge, which was near the CR, and I lost grip to my phone due to slippery, sweaty hands. I tried to grab it, in vain, and instead fell into a almost full water container. It was a small one but my whole phone was engulfed in water. Grabbing it out and quickly trying to dry everything I can inside and out, it worked...for a small amount of time. After like, 5 minutes of using the phone after the event, when I tried to enter my mobile Facebook and accidentally accessing the FB Camera, my screen suddenly froze in place. I eventually resorted to removing the battery and discovering that even the battery was wet, dried it using a small cloth piece. After that, my phone was stuck on black, even though I see the red light on the top of the phone (which usually tells that either it's charging or it's turning on). After that, I resorted to charging my phone. This time, I heard it's turn-on sound. And I tried interacting with the power button. Usually when I'm about to turn off/restart the phone, when I long-press the said button, it vibrates for a short while. It did vibrate, but of course since it's black screen nothing happens, even when I try to interact with it. Me being sleepy, I charged it and slept. Next day, I talked to a friend about the situation, and he recommended to put the phone to a rice container to dry everything off the phone, and keep it there for half a/whole day. I tried that, and after I got home from school I came back only to see the same problem.
Anyone knows how to solve this problem? Should I replace my phone or is there still hope for it?
Any answer would be appreciated. Thank you.

There isn't much hope alas. Switching on while the phone was still wet inside will have done damage. The water and any deposits left behind will do more, progressively over time. This explains in greater detail:
