Question: how long are you supposed to keep a phone in rice?
Answer: Many folks swear by stuffing your phone in a bag of dry rice, and letting it sit for 24 to 36 hours or more. This is cheap, easy, and can be done in a pinch. But this method could have some negatives: If the rice absorbs the water well, you may be left with a mushy rice mess stuck in its creases and I/O ports.
