water damaged Tmobile Revvl

I dropped my android in the toilet last Thursday November 9, 2017 and it turned off and it kept going to the powered by android screen, on and off. It came back on that Saturday and I have been using it since with no problems. Today I got to work and was talking to my sister on it and it turned back off and has been doing the same thing it did the day I dropped it in the toilet with the exception of it will turn completely back on, but when I go to text someone or do anything with it, it turns right back off.
