I am surprised how many people drop their phones in the toilet!
I don't have any advice but wanted to let you know your not alone, although mine is not a toilet story.
My friend and I were just talking the other day and her DS4 poured sugar on her laptop keyboard and it's fried. She wasn't happy.
When my DS was 9 he decided to see how the autostart remote for my van works and took it apart. I tried to put it back together but couldn't and the remote model is discontinued and they cannot reprogram a new remote, so I am told I'm outta luck. I have a perfectly good auto starter that I can't use, we live in MN, it was -12 yesterday.
I really hope the rice trick works for you!!!
