Samsung A5 2017 moisture detected

[Wena39]

Hi. My Samsung A5 2017 has recently started notifying me of moisture detected in usb port. I have never put my phone in water and never got even slightly wet in rain. How do I stop this notification from coming back again and again? Thanks

Check the USB port to make sure there's no debris in there. Use a can of compressed air to blow it out, or a Q-tip dipped in rubbing alcohol to clean the contacts. If that doesn't help, see if it still happens in Safe Mode: How do I use Safe Mode on my Galaxy A5?. If it does, then contact Samsung for warranty repair.
