079*******4?

I dropped my samsung galaxy phone in the toilet. I didn't notice until after an hour. Picked it up immediately means, after an hour, I dried with tissues etc for a while and put it in a bag of rice. After 4 days I took it out and put the battery in , it immediately became very hot. So I took out the battery and cooled it down. Then put it again and started charging but nothing happened. Is it because it will take some itme to get charged, because the battery is completely drained or my phone is broken completely? Please help me. I am paying a lot of money for it monthly.
