iPhone dropped in water, won't stop vibrating

Kay so this iPhone was dropped in water, after it fell it started vibrating and won't stop, I immediately unscrewed it and took the screen out and put them both in a bowl of rice, did not turn it off.

Has it ever happen to anyone that the iPhone won't stop vibrating after a water damage?
Should I remove the logic board too?
How long should I leave it in the rice bowl?
Thanks
