I know how frustrating this is. I've had it happen myself. I understand that you stated that there has been no contact with any type of liquid. However, I am including a couple of articles that would address this issue.
Check the liquid damage indicator on the phone
Moisture in water-resistant Samsung phone's charging port
I recommend trying the factory reset, as recommended by @Fathertuckett. Perform a factory reset on your Galaxy phone
If you are still receiving the pop-up, I would recommend having the phone evaluated by a certified technician. You can find the nearest authorized service center using this link: https://www.ubreakifix.com/samsung
Samsung also offers a mail-in option for service. For service options, Please reach out to us via one of the following options: 1. Facebook Messenger: http://m.me/samsungsupport 2. Twitter: https://twitter.com/messages/compose?recipient_id=18768513- 3. Private Message: http://bit.ly/2XERsky
