Is Moisture Detection on Samsung an Error?

If your Samsung phone is rated with Ingress Protection or IP68, it means that the OEM has made use of adhesives, gaskets, and seals to make sure moisture or water drops don’t go inside the device. Even the speakers in such devices are fitted with mesh grilles.

Now, we all know about the dangerous enmity between water and electricity. If the charging port on your Samsung Galaxy device is wet or humid, it might cause a short-circuit, damage the device and make it unfunctional.

The moisture detection message on Samsung Galaxy devices is not actually an error or bug but a safety measure to protect your device. The moisture detection sensor intelligently stops the device from charging automatically as soon as it detects moisture in the charging port or the USB cable.

If you are getting the “Moisture has been detected” warning, it doesn’t mean that your Samsung phone was in direct contact with water. Most of the time, the charging error might be caused by a very humid atmosphere and sweating, especially if you live in a hot and humid area. The presence of dirt in the USB port of your Samsung device might also cause charging issues. Many users have reported getting the moisture-detected warning when the charging port gets dirty.

If you are having problems with charging your Samsung Galaxy smartphone or tablet, it may be due to one of the following reasons:

  • The charging port is wet or it has moisture residuals.
  • Dust particles have built up inside the USB port.
  • The charging port has been damaged due to corrosion, careless usage, or the use of incompatible charging accessories.

Fixing Moisture Detected Error on Samsung

So, what do you do when your phone says moisture has been detected? Below, are some easy fixes to get rid of the annoying moisture-detected warning notification if your Samsung phone has recently been exposed to moisture.

  1. Use a soft dry cloth to gently wipe your Samsung phone and shake it while keeping the charging port down. Then place it in the open air or under the ceiling fan for some time so that the moisture evaporates.
  2. Take a plastic or rubber toothpick, wrap it with tissue paper or thin cotton cloth, and move it gently inside the USB port to wipe the moisture.
  3. You can also try to rinse the charging port with distilled water, alcohol, or petrol and then wipe it using paper towel strips.
  4. Get an alcohol swab insert it inside the charging port and move around it and leave your phone for some minutes to let it dry.
  5. If you got a hairdryer, use it to blow mildly hot air at slow or moderate speed into the USB port from different angles for a couple of minutes to ensure that moisture dries up.
  6. Blow compressed air at low pressure into the USB port.
  7. We are all aware of the hygroscopic qualities of rice. Rice grains absorb RH (relative humidity). If you are getting moisture-detected error on your Samsung device, stuff your phone in a bag of dry rice and leave it there for an hour or so. The rice grains will suck all moisture from the device and you’ll get rid of the annoying charging problems due to moisture detection. If your phone got wet with seawater, do not place it in rice grains as salty water is sticky. You should rinse and wipe your Samsung phone first with clean and fresh water.
  8. Silica gel is considered a better moisture absorbent than rice. You can also try putting your phone in a jar with Silica gel for optimal results.
  9.  If you are still getting moisture detected error, you should try tweezers. Get a set of tweezers and gently rub the plastic part that holds the charging contacts to remove any corrosion and dirt particles blocking device charging.
  10. Sign out of your Samsung account: Well, I haven’t tried this tip personally, but one of my friends claimed that he was able to get rid of the moisture-detected error on his Galaxy S10 simply by signing out of his Samsung account. Check out the screenshots attached below to learn the steps o sign out of your Samsung Account on your Galaxy device.

  11. Wipe Cache partition: Before you get to the next tip, you should also try wiping the cache partition on your Samsung device via Recovery Mode.
  12. Boot into the Safe Mode: Safe Mode is a diagnostic tool for Android devices.

A rouge 3rd-party app might trigger serious problems including the moisture bug. Reboot your Samsung device into the Safe Mode and plug in the charging cable. If you no longer get the moisture detected error, it means the real culprit is some recently installed app. You can uninstall the suspicious apps one by one in Safe Mode and fix the charging issue.

What to do if the Charging Port is Damaged?

If you think that the charging port of your Galaxy device is bone dry and clean, there may be some hardware-related issue either with the USB port, moisture detection sensor, or the USB Type C charging pin.

  • First of all, try using a different USB C Type C cable to charge your phone. Doing so will rule out the possibility of a damaged USB port. If the moisture detected bug has disappeared, it’s time to get a new charging cable.
  • To fix the damaged charging port, you’ll need to visit the nearest Samsung Care. However, there are still some other workarounds mentioned below that you must try first.
