If you get your phone wet the most important thing is to not try and charge it or continually try to turn it on/off. It needs to be opened up and dried correctly using chemicals while the battery is disconnected.
Putting a wet phone in rice is not only a waste of rice but a very old wives tale that simply does not work.
So, got a wet phone? Get it to the Phone Surgeon ASAP @ 122 Charters Towers Road, Hermit Park QLD 4812. Ph 4771 6411
