My phone got some splash water. Unfortunately some water drops landed in the usb charging port. The phone gave me the error message that it detected moisture and i should dry it.
At some point the phone died because of low battery. I did not have charged it yet because of the concernings that the water and charging could damage the phone.
UPDATE: i used paper towels and let it dry overnight. I charged and there was no warnings.
If it’s just a few drops in an open port, you could have probably just used a paper towel to wipe it out and then set it in front of a fan for an hour or so to make sure anything left evaporates.
Don’t do the rice thing. Then you’ll just be getting other dust and crap in the ports.
