Please help, I recently dropped my phone in water for a second or two. Once I had dried the phone out, it turned on and seemed to be working ok. However after a little time, the screen came unresponsive to drag control so I could not unlock. After loads of times trying I got the screen active and the phone works in every way (internet, video, fb, twitter all work) but then the touch screen stops working. Any ideas anyone pls!!!!!
