Moisture Detected Error on Samsung

Most high-end phones come with IP certification and claim to be water and dust proof/resistant. The Samsung Galaxy S7, S8, S9, and Note 9 also come with IP68 (6 is for dust and 8 is for water). Moisture detected or “moisture has been detected” error in charging port is one of the commonest issues the users of Samsung Galaxy S7, Galaxy S8, Galaxy S9 and Note 9 encounter at some point of time. Here’s how you can fix moisture detected error on Samsung or non-Samsung devices. When you have this error, you’ll see a warning message pop up and a water-drop icon on the status bar. The warning shows up when you plug in the charging pin to the Samsung device and it refuses to charge, saying:

Moisture has been detected. Unplug the charger and wait until both the charger and USB port are dry.

One of the things that modern smartphone manufacturers use as a unique selling point for their high-end devices is adding the “waterproof” feature to them. Everybody wants to have a phone that doesn’t refuse to function properly or dies forever if it comes into contact with water accidentally. In fact, people want to own a phone that allows them to shoot underwater pics.

Sony has been making waterproof devices, especially the Xperia Z series, for years. Personally, I have stopped relying on the waterproof technology used in modern smartphones since my Xperia Z3 made its way to the world of the dead shortly after I dipped it into a bucket of water to test Sony’s claim that the Z3 is waterproof. It happened the same day I purchased the device, and by refusing to replace or repair my new phone, the service center added more salt to my wound. I used to have the Galaxy S6 Edge, S7 Edge, and the S8 Plus in the past and currently, have the S9 Plus, but never did I gather the guts to test any of them.

Actually, water is the biggest enemy of electronic gadgets and making a phone that can survive inside water, even to a certain duration and pressure, is not an easy job. Since it’s impossible to imagine a smartphone without stereo speakers, microphone, earphone pin socket and charging port, it’s also hard to imagine a phone with no holes.

With the launch of the Galaxy S7/S7 Edge, Samsung brought the IP68 certification to their flagship range. It means that these devices can withstand water pressure up to 1.5 meters for a duration of 30 minutes. The Galaxy S8, Galaxy S9 and Note 9 are also water and dust proof.

Samsung has made heavy use of gaskets, sticky adhesives, and seals on the Galaxy S7/S7 Edge, Galaxy S8/S8 Plus, Galaxy S9/S9 Plus and Note 9 to protect the internal components from letting water or moisture inside the device. As for the speakers, Samsung has fitted mesh grille for keeping water out. To save the device from a possible short-circuit the power jack on the Galaxy devices are powered by software that gives it the signal to stop responding.

Maintaining Water and Dust Resistance

Now here’re some instructions from Samsung as mentioned in the device manual. Follow these tips to maintain the water and dust resistance of your Samsung and other Android devices.

  • Do not immerse the device in water deeper than 1.5 meters and keep it submerged for more than 30 minutes.
  • Do not expose the device to water moving with force, such as running water from taps, ocean waves, or waterfalls.
  • If the device is exposed to clean water, dry it thoroughly with a clean, soft cloth. If the device is exposed to other liquids, rinse it with clean water and dry it thoroughly with a soft, water-absorbing cloth.
  • If the device has been immersed in water or the microphone, speaker, or receiver is wet, sound may not be heard clearly during a call. You must dry your phone properly before using it.
  • The touchscreen and other features may not work properly if the device is used in water.
  • Remember, water and dust resistance devices are tested in a controlled environment before getting IP certification.


Samsung claims to make heavy use of gaskets, sticky adhesives and seals to protect the internal components from letting water or moisture inside the device. As for the speakers, Samsung has fitted mesh grille for keeping water out. To save the device from a possible short-circuit the power jack on the Galaxy S7/S8/S9/Note 9 are powered by software that gives it the intelligence to stop responding to an electrical connection when the charging pin is plugged in.

Having read the above details, any Galaxy S7/S8/S9/ Galaxy Note 9 users might start dreaming about some underwater adventure but then, there’s a problem. The device might stop charging if it detects any kind of moisture inside because of the moisture-detecting stickers fitted in the device. Moreover, Samsung has applied no water repellant coating on the circuit boards and that make this device more vulnerable to short-circuiting and corrosion.

The Samsung Galaxy S7/S8/S9 is water resistant and it’s really an ensuring safety feature against accidental exposure to water. However, if you become very enthusiastic about it and deliberately try to expose it to water, Samsung might refuse your claims and you might lose your hands off the device warranty.

If you have recently exposed your Galaxy S7, Galaxy S8, Galaxy S9 or Note 9 to water and have been encountering “Moisture has been detected” error when you try to charge it, below are a few tips that you should try to fix the issue.

The error pops up, especially when the sensor detects any moisture inside the charging port. As I said above, this is a safety measure by the OEM to protect the device from short-circuiting. To some, it might sound like a sensible safeguard, while for some it might be the point that defeats IP68 certification.

Anyway, given below are a few handy tips to get the moisture out of your device and fix the Moisture Detected Error issue on Samsung Galaxy phones.

Tips to Fix Moisture Detected Error

Try these things to solve the moisture detected error on Samsung devices:

  • Soft Cotton Cloth: The first thing you should try is to wipe your S7/S8/S9/Note 9 with a soft cotton cloth properly and then shake it with the charging port facing down to remove any excess water inside the USB port.
  • Vacuum Cleaner: Use a vacuum cleaner to suck all the ports: charging port, speaker, aux port, earpiece speaker, buttons any holes. Doing so might fix the “moisture detected” error on your S7.
  • Hair Dryer: Don’t blow air into the charging port as the water or moisture may further go inside the device. Try a hair dryer instead to vaporize water and get rid of the moisture. Make sure to keep the hair dryer temperature at a low or moderate level so that the device doesn’t get damaged by heat. Set the temperature level of the dryer to “1” or “2”. Your target is to remove the moisture only, remember! Use the dryer for at least two-three minutes and blow the charging port from different angles.  Now, take a dry piece of cloth and try wiping any possible moisture left in the USB port. Now, take a dry piece of cloth and try wiping any possible moisture left in the USB port.
  • Rice: You must be familiar with rice’s great quality of absorbing moisture out of things. Popping your Galaxy device in a rice box for 30-60 minutes might also help you fix the “moisture detected” issue. Give it a try!
  • Alcohol Swab: Get an alcohol swab, and gently move it into the USB port. Let it dry for a couple of minutes.
  • Tweezers: If wiping with a cloth, dipping into rice or the hair dryer trick doesn’t work for you, there’s one more thing that you can try. Get a set of tweezers and slightly push up on the plastic piece that holds the contacts inside the charging port. Also, lightly scrape the contacts with the tweezers to remove any possible corrosion on them. I would caution anybody who is willing to try this to be very gentle and careful while trying this.
  • Different Charging Cable: Using a different charging cable might also work.
  • Use a Wireless Charger: Well, using a wireless charger is not actually a fix. However, if you want to charge your Samsung phone while getting the moisture detected error, you can use a wireless charger to charge it.

Having tried the things suggested above, reboot your Galaxy S7/S7 Edge/S8/S9/Note 9 and plug in the charger pin. You should now able to charge the device normally.
