Iphone XR fell into salt water at the beach

So my Iphone XR dropped out of my pocket at the beach into salt water but I retrieved it before 15 seconds of it being there. I instantly sucked the water out of the speakers and charging port as soon as I had picked it back up. The phone did work but it was slightly bugging, the screen was moving up and down just a bit, as if the phone had been dropped. Was not too serious until it started glitching on the lock screen where it happened to disable my phone for a minute as it started to type in random passwords, something you'd expect. I managed to power it off completely after a few attempts which is when the problem began. It didn't turn on but you could see the black screen slightly lighten up and was vibrating after I turned the silence button on and off and has since not turned on for about 8 hours now. I tried to blow dry the phone in hopes of it drying it up better than I did with my shirt but again, no results. I am getting worried seeing how I recently fixed my phone with there being no issues with it. I also tried to leave it out in the open with nothing happening. that dim light that the screen made has also gone along with the little vibrations that gave me some kind of hope for the phone. Maybe I have to wait for longer? I am growing anxious and at a fast rate so if anyone can somehow help, please do let me know immediately and thank you for your time.

just edited it, its my first time using the community tab on here.

My relative said her phone had dropped in water for 10 minutes and she had taken it out, left it alone for 3 days and it worked just as fine as it did before. I'm at turkey right now with my family and I still feel there is the chance it'll be alright after a couple of days. Do you genuinely think it is completely done for?

That's the thing, I'm currently at turkey on vacation with my family.

Thank you.
