My touchscreen has all of a sudden stopped working. I went to a pond and while standing in the water. i pulled it out of my pocket, took a picture, then put it in the center of my bra, screen against my skin, and when i pulled it out again there was a bit of sweat on the screen and the touch wasnt working. I turned it off, took everything out (battery, mem card, SD card) and dried it with a hair dryer for a bit but it still isnt working!! Help??
