Story: Mom accidentally left her 4S on nightstand and sloshed water on it. Phone vibrated and shut off. Put in bag of rice for five days. Problem: Rear camera and LED flash do not appear to be working. However, front camera DOES work(I heard if one didn't work than the other didn't). Sometimes gets No Service after reboot. Does anyone have some sort of tip to get the camera and LED flash to work? She refuses to pay $199 for a replacement(she CAN afford this) and we bought it for her because she needed a better camera and siri(for when she's driving in the car). I would take off the back but don't want to void the warranty(I know it's voided but they wont replace it for $199 if they see the device was tampered with or if the phone is in more than one piece). I am also trying to explain to her that the device my just corrode more and that the phone would just stop working. Unfortunately, she refuses to believe this.
