This exact thing happened to me. After I got it out of the toilet, it started glitching with lines going up and down the screen. I put it in rice and left it there for a couple of days , and came back to it still not working. A day later I just gave up on trying to fix the phone myself and went to a specialist. He fixed the water damage and got the stuck rice out of the charger hole! I definitely recommend going to a repair place if all else doesn't work (even though going to a repair place costs a fortune).
