My phone screen wont turn on

Hiii! So my phone is a samsung galaxy A02 or A03 and I wanted to listen to music one night while I showered. So,I sit it on like this shelf outside of the shower, and shut the curtain so it does not get wet, well somehow I think it got wet bc after i showered it almost looked like ther was water behind the screen (like little spots or blotches) idk how to explain it. Well, I put it in rice for the night,take it out next morning and it doesnt turn on. Later that night, I press the volume down and power on button and it turned on. But now today, I tried to do it and it wont turn on. Like I plugged it in but I cant tell if it charged or not cuz the screen wont turn on, its just black. I tried to do the power button and volume down button like 8 times, and out of the 8 times it never worked. Like I can hear it vibrate when I do it, its just the screen is completely black. But yeah, I do the volume down button and the power on button , amd it vibrates like its turning on, it just doesnt turn on, its just completely black. Please help me tho!! idk what to do
