I have the Samsung Galaxy Tab A 2017. I have been getting this warning that there is moisture in the charging port. I can only charge normally with the tablet on. When I charge with the tablet off the moisture warning comes up and the tsblet won't charge. I've tried all the methods and solutions to fix the problem with no success. I paid $179 for it. I called Samsung and they want me to pay $119 dollars to repair it. Almost the entire price of the tablet. Mind you I bought it last June of 2018. I refuse to pay that ridiculous price! Any suggestions from the Samsung community? Your help is appreciated.
