Samsung Warning: Unplug charger immediately

How to solve the "Warning: Unplug charger immediately. We've detected moisture or foreign material in your charging/USB port"

In case you've got the Warning: Unplug charger immediately message on your Samsung smartphone but there is neither moisture or anything else in your phone port, well you are not the only one. 

It seems that many consumes received this warning message on their phones without a reason. We are not sure what may have caused the issue on our case, noticed on the Galaxy Note 9 but there are some suggestion for quick fixes that we found online.

How to solve the Warning: Unplug charger immediately issue

First of all we would recommend what Samsung notifies on the screen during the warning message - check the port for liquids or anything that may look wrong with it. If there is some moisture, then let it dry for couple of hours and try again.

Samsung also suggests the workaround of charging the affected phone wirelessly. 

One of the popular solutions that we found online by other consumers is to turn off the phone while being unplugged then plug it in the charger and then turn the phone on again. That seemed to work for some but did not resolve it for many others. 

What happened with our Note 9 - after we run out of battery we plugged the phone in the charger and it seems to start charging up as usual. We will give it some time and see if it pops up again.
