These are not the only reports we received so far on this error. But we just added a few as a reference. Instead of suggesting them one by one, we have come up with this guide which should help you fix the moisture detected error on Galaxy S8.

Before we go through the solutions, let’s check out why this error happens.

Why does Galaxy S8 moisture Detected Error Occur?

The moisture detected in charging port of the Galaxy S8 occurs when the USB port of the phone is exposed to water. While the phone may be water resistant, one must ensure that the phone stays way from water. The water resistance on Galaxy S8 protects its internals from getting damaged by moisture, but the ports on the outside are still exposed.

Interestingly, many users have reported that their Galaxy S8 had never been exposed to water, but still they get the moisture detected in charging port error. It happens when you live in a humid area where the moisture in the air can also damage the charging port of your Galaxy S8.

Besides these, in some cases, that charging cable can also be blamed for the moisture error in Galaxy S8. If the cable has been exposed to water or moisture, it can be transferred to the phone’s USB port while you connect it for charging or data syncing. It can cause corrosion on the contact points of either of the charging ports for long-term damage.

Things to Avoid When Moisture Detected in Galaxy S8

The worst thing you can do to your Galaxy S8 when there is moisture in its charging port is blowing hot air into it using the hair dryer. While it may look like an easy solution to dry out any moisture deposit, it does more damage than doing good. The air you’d blow into the Galaxy S8’s charging port will push the water further inside the phone to cause much more damage than it would have done otherwise.

The Type-C USB port on the Galaxy S8 is so tiny that it is quite difficult to look for any corrosion inside it without any magnification. You can peek inside it using a flashlight and the magnifying glass at your home itself. It is always suggested to contact the company in such situation, but you can try to fix the moisture issue yourself before taking a professional help.

Since the ‘moisture detected in charging port’ error hasn’t gone yet, it is assumed that the damage has already been done. Now just turn your Galaxy S8 down and gently clean the USB port from inside using a cotton swab. Just be very gentle and see if it removes anything. Then dip the cotton swab in some rubbing alcohol and clean the port again in the same gentle manner. Using the two will clean the moisture build up and the port’s contact points.

You can do this process for the USB port of the phone’s charging cable if you aren’t sure where the moisture came from. Turn the phone back on and connect the charger to check if the error occurs again.
