Hey Admir, I had a similar Issue, first thing to do dont turn the phone on and rice bag dosent do anything sadly. Best one ive heard on here is “rice is good to eat but not for phones” :D Take your phone apart and clean any water you find, then follow this guide Reparación de daños líquidos en iPhone Also order a new battery and a new screen, you may not need them but the last one i did that was water damaged both the screen and the battery went to replaced them and cleaned the board and wola working phone :D hope this helps.
