My tablet fell in water I dried it up but after a week when 1 charge was left I put it for charging and while charging I touched the screen and then it started having touchscreen problem and I wiped the data and rebooted it. But still I couldn't get the screen to work properly and after more than 2 weeks later I switched it off using the power off button and Now It Is Not Turning On. Please help me, I can't afford a new tab and I use it for my studies. Please, please help
