Phone working but screen not turning ON

Hi, i just want to ask about my note8. Last night we went swimming and i always take photos using my note on or under water. But this time it did something different and the power option keeps on popping. So i took it out of the pool and let it dry. This time the phone still works fine no issues. But it was drupping water from the power button which concerns me so i just placed it at the table to dry out after an hour or so i tried using the phone but the screen wont turn ON. Phone works. But no screen. Phone rings, vibrates etc when someone tries to call or send messages. But no light on screen. Can this be just moisture? If i let my phone dry for a couple of days will it go bacl to normal?
