water got all over my sons tablet and it worked perfectly fine after. you could see some of the water inside it though. we shut it off quickly because we had to be somewhere and we were already late so we decided to leave it. came back a few hours later, 4 at the most, and didn't touch it until next morning. now it still works, we feel it vibrating and all, but the screen is completely black. is there anyway to fix this or would i have to get a new one?
