I dropped my phone in the water. I was in the toilet and then my phone slipped and fell down. Thank god it was clean, but my phone immediately died after that. I instantly opened it up, took out the battery and then dry it off with some tissue and then left it to dry. I (stupidly) turned it on a while ago and it's buttons (Home, Back, and Settings I guess) worked, but the touchscreen didn't. After a while, there this whirring sound that sometimes increase in volume, then whittle down and then it repeats. I immediately remove the battery when the whirring sound increases.
