My back button on the Galaxy S6 doesn't work after it fell into a glass of water. Is there anyway to fix it?

[AC Question]

My back button on the Galaxy S6 doesn't work after it fell into a glass of water.

When I turn the phone on, the back button lights up but stutters away and eventually doesn't light up anymore in the lock screen. It has no function. The button that shows the different windows has full function though.

This will have been caused by the water damage. Have you tried the old trick of turning the device of and putting it in a bag of rice for a few days? let the rice absorb the water, it might work. If it doesn't do you have insurance on the phone?
