Fix Galaxy Note 8 Moisture detected in charging port error


Moisture detected in charging port is a common error on Samsung Galaxy handsets. The error is self-explanatory. Whenever moisture sticks up in the charging port of your phone, it will refuse to charge and pop up this error. This happens mostly when you have just water-tested your water-resistant phone and the water sticks up in the charging port of the phone. Other than this, if you live in a very humid area, your phone can build up moisture in the charging port and refuse to charge. Touching the charging port of the phone with wet hands can also drop the water inside and result in this error.

Moisture Detection Error Background

There’s a whole background to the Moisture detected in charging port error. You must not have seen this error on the older Samsung Galaxy handsets. That is because Samsung just started making water-resistant handsets very recently. All the water-resistant handsets have this property. The water-resistant Samsung Galaxy phones have a moisture sticker inside the charging port, which works as a moisture detector. If there is moisture in the charging port of the phone, and one connects the charger, this stripe will immediately inform the user through a pop-up notification on the phone. The moisture sensor is programmed to detect and notify the user. The sole purpose of this error is to protect your phone from a potential short circuit.

Now, why does the phone refuse to charge if it’s already water-resistant? Well, that is because, the phone is water resistant, the circuits inside the phone are not. Manufacturers like Samsung, Sony, LG, and others use rubber gaskets to protect the components of the phone from water. The gaskets are not applied on the electric-circuits inside the phone. Gaskets are only applied in the phone to stop the water from getting inside whenever the phone is exposed to water.

If you are testing your phone’s water-resistance of your phone by dipping inside a bowl or bucket of water for a while, the water will definitely get inside the charging port. The gaskets will prevent the water from entering the phone and hitting the electric circuits inside. Until the water dries off from the charging port, it will keep giving you the error so that there’s absolutely no damage done to the phone. At times, it becomes completely annoying when you are unable to resolve this issue. If you have faced such an issue on your phone and you are on this post to find a solution, then let us help you out from here.

Here are a few snapshots of the Samsung manual explaining the water and dust resistance feature of the Samsung Galaxy Note 8.

Note: Try these solutions one by one.

The Cloth Solution

  1. First of all, you should try wiping off the charging port using a towel or any other suitable cloth.
  2. Shake the phone in order to let all the water out and then wipe it off again.
  3. Try looking into the charging port if there’s moisture left inside. If the phone still gives an error, move onto the next fix.

The Vacuum Cleaner Solution

Got a vacuum cleaner? Let’s fix the phone using a vacuum cleaner then. All you have to do is to suck the moisture/water out of all the holes of the phone. Suck the moisture from the speaker holes, the charging port and the headphone jack. Using vacuum cleaner is the safest way to fix the phone.

The Hair Dryer Solution

Take a hair dryer, turn it on. Set it’s temperature to 1 at max. Do not increase the temperature as we only want to dry off the moisture. Blow the air right into the charging port, the headphone jack and the speaker holes in the phone. Use the hair dryer for a few minutes to completely wipe off the moisture. Once done, you can try putting your phone back to charging.

The Qtip Solution

First of all, take a Qtip and try cleaning the charging port of the phone. Check the Qtip if it pulls out any moisture from the port. If the dry Qtip doesn’t work good enough, you can get rubbing alcohol. Dip the Qtip in the rubbing alcohol and then use it to wipe off the charging port. Let it dry for a while and it will most probably fix your phone.

The Tweezer Solution

If you find out that the charging port of your phone is filled up with corrosion because of water, you can use a tweezer to scrape it in order to remove corrosion. This is a tricky and a risky solution. You have to be very careful while scraping the charging port of your phone. Do this one at your own risk.

If the solutions above fail to work for you, you can try wiping the cache of your phone. If you think that there is no moisture in the phone and the error has just got stuck in the software, you may want to flash a stock firmware on your phone. Here’s how you can re-install an official software on the Samsung Galaxy Note 8.
