I also dropped my phone in the water 4 days ago

Hi, I also would like to know if someone could help me and tell me how to fix my phone because I also dropped my phone in the water 4 days ago, its an android and its turned on but its stuck on the lock screen. I put my phone in rice for those 4 days and then I turned it back on and the screen still isn't still letting me swipe, so I'm not able to turn my phone back off unless I am able to tap the screen and get to the home screen. Please help I don't want my Mom to spend $800 on a phone again and she'll keep on bringing up how she keeps on spending more money on my electronics again. I hope someone has any info.
