Try rebooting the software by removing the battery for a couple of minutes

Buttons might be sticking.

Very importat!!! Do not power the device on if it is off. If it is on, power it off. Next dry it off as best you can. If you can remove the back and battery case, do so and remove any additional liquid in those areas. After that, place your phone in a bag of rice. The rice will absorb the additional moisture that is trapped inside the phone, and after about 24 to 48 hours, if there was no damage done to the circuitry inside the phone, it should work just as good as it ever did.
