My coolpad note 3 lite fell in a bucket of water few months ago. I took it out immediately and dried it with a cloth after taking out the sim card and the memory card. Then I put it in rice for a day. The issue was that was I put it for charging it actually turned on, vibated and sometimes I saw a little white flashing on the screen which doesn't turn on( it's blank) so I took it to the repair shop and he said its an issue of the display but he wasnt sure. It's been 3 months and when I tried connecting it to the power source the same problem ( it vibrates but the screen is blank and sometimes light flashes on the screen) turned up. How do I fix it?
