Hey, I see that things like these can scare phone users as sometimes their minds race to a conclusion that is almost always not what ends ep happening. simply let your phone dry out . give it time, as sometimes water can go deeper within the phone, making it harder to dry. I hope this helped. if this does not work, go to your nearest samsung store and find out its issue. at this time an s3 is almost never used, as an upgrade to s5 and above is a smart move. good luck!
