I was having one of those bad weeks this last summer and when my phone alarm sounded I picked it up and put it on a 5 minute delay and put it back down. IN A GLASS OF WATER!!!! I woke up a hour later wondering why I felt so rested and realized what I had done.

Don't try to power it on put it in instant rice and leave it for a dew days. Maybe it will work. That's what I did and I'm using that phone now to type this post.
Good luck!
