Phone screen stays dimly lit in standby mode

[Sisman9]

Earlier today u dropped my phone in water I quickly retrieved it and it's working perfectly but for some reason why I put my phone in standby I gets a dim Grey in the corners and a thin white line on the top and bottom and instead of being completely black the whole screen is like a dark Grey, and I'm wondering if there is anything I can do to prevent this, because it will obv decrease Mt battery life and will probably be harmful to the screen

If you haven't already, shut down, pull the battery, wait a few minutes, and try again.

Even better, if you have the time, shut the phone down, pull the battery, then stick the phone and battery in a sealed ziplock bag or plastic storage container filled with rice. For at least a few hours, 24 hours if you can manage it. The rice will help absorb any moisture still left in the phone.
