It is a true IP 68 waterproof, since the current situations phones are are also need to disinfect.. for the same every day I used to wash the phone..
I was doing the same once I switch off the phone and do the washing, used to keep it for 15-30 minutes, after that wipe out with normal tissue on the charging port and the earphone port. That's it!!!
I used to do this now one month. I didn't found any issue as of now.. Thanks Samsung for such a good product ..
