My girlfriend dropped her 6 week old 4s into the toilet. Straight away i but it in a bag of rice and left it for 3 days. Now plugged it into charger battery screen came up to say needs charging. Charged it for few hours but when i press the home button its just blank. Yet i know its turned on as i can key in the passcode and hear the clicks of button pressing. It'll ring but no screen yet it the screen works when plugged in at first when it has a dead battery. Anyone have this and fixed it ? Gonna try restore it tomorrow too see if it helps.
