My Xperia S was out in the rain, in 8 hours. When i found it, it didn't worked, but after a few hours it started working. But there is now dew in front of the front camera, how can i remove it?
Unfortunately it sounds like you can not do nothing about it yourself.
I recommend you to contact your local support and repair center to see if they possibly can do something about this:
