Your phone “Samsung Galaxy A9 2018” is not a waterproof phone and doesn't have the IP68 or IP67 ratings which means it's not a water resistant phone.
Also your phone does has a type-c usb port and a 3.5 audio port not to mention the speakers and its all open ports, so i recommend that if you have the knowledge of working on phones “you did teardown a phone before”, just open it and replace the usb port then dry it with a heat gun. If not, just go to someone who can to prevent yourself from damaging your phone or hurting yourself.

Notice! Even if the phone is water resistant, it's not a 100%. Water still may leak inside of it. And thats why the IP68 rating guarantee the phone only for half an hour at the depth of 1 merer in a regular conditions..
