My phone is wet and the media sound is off

[Hanm7md]

I accidently wet my phone but only in the bottom. There was no significant damge but when i try to open any video or music the sound is not on although the ringtone and alarm are working. i tried to turn the volume up but it's not working. The device also turn it down as soon as i turn it up.

I don't know if i should open the phone back cover or not. i just turn it off and left it on rice.

Turn it off now and put it in a bag of rice and let it dry out for at least 48 hours.
