This troubleshooting article talks about fixing “Moisture detected” error on Galaxy S10. As a water-resistant device, the Galaxy S10 should be safe from occasional splashes and tiny amount of moisture. If wet, all a user needs to do is to wipe the device and use it as normal. However, there had been cases wherein “Moisture detected” error pops up even though the phone has been dried. “Moisture detected” error prevents charging via USB port so it can present a problem when it comes to topping up the battery. Learn how to deal with this error below.
How to fix Galaxy S10 “Moisture detected” error
Knowing what is the cause of “Moisture detected” error is the key to solving it. There are a number of factors that you can check to do that. Below are the concrete troubleshooting steps that you can try.
Has your Galaxy S10 taken a dip? By design, “Moisture detected” error is supposed to show when the phone’s charging port is wet. So, if you recently used the phone in wet or humid environment, the error is just a normal reaction from the device. What you need to do in this case is to allow the phone to dry. Once the charging port is clear of water or moisture, the error should also go away. Based on experience, a Galaxy device will give you ample warning to remind you of a wet charging port. If you try to connect a charging cable to a wet port, there will be an alarm telling you to disconnect. This sound alarm will only stop once the system detects that you’ve disconnected the charging port. Dry the phone by gently shaking it. This is normally enough to get rid of water or moisture in the port.
In normal temperature, water will usually evaporate on its own within two hours. Let your Galaxy S10 rest near a source of gentle heat such as the back of a TV or computer. If you exposed the device to other liquid other than fresh water, rinse the phone with fresh water thoroughly to remove it. Then, dry the device with clean, soft cloth.
Dry your phone. If Moisture detected” error remains at this time, it’s possible that you failed to properly get rid of moisture in the charging port. The natural process of evaporation may not be enough to clear the remaining moisture so you’ll need to further dry the phone. There are two home remedies for this depending on the availability of material for you.
A common way to dry wet electronics is by using uncooked rice. After wiping the device dry, put it inside a container and cover it with rice. Make sure that uncooked rice covers the device fully to “bury” in the container. Then, leave it at that state for at least 40 hours or longer. This should be enough time to allow rice to absorb moisture from the port. Make sure to seal the container throughout this process.
Alternatively, you can use several packs of silica gel instead of rice. You can get silica gel from your local crafts store. This is a more effective way to get rid of moisture from your phone. Again, make sure to seal the container before leaving the device in there for at least 48 hours.
If money is not an issue and you need to dry the phone fast, you can allow a professional do the drying for you. Visit an electronics shop or repair shop that offers drying service. There’s a set of professional tools that technicians use to dry electronic parts faster. Talk to your local repair shop for details.
Charge your phone while it’s off. If you think that your phone is running out of power soon and you badly need it, try to charge it while it’s off. Again, you want to make sure that your phone’s charging port is dry to avoid damaging the system. Should the error remain, proceed to the next steps to fix possible app or software problems.
Safe mode. If “Moisture detected” error started going off after adding an app, that app is most probably the one to blame. Remove the app from the system and see what happens.
If you have no idea which of your apps is causing the trouble, you can restart the phone to safe mode. In this mode, all third party apps are blocked and only preinstalled ones will be allowed to run. If your S10 charges on safe mode and no error shows, you can bet there’s a bad app to blame. It may be poor app coding or it’s a malware.
To restart your phone to safe mode:
- Turn the device off.
- Press and hold the Power key past the model name screen.
- When “SAMSUNG” appears on the screen, release the Power key.
- Immediately after releasing the Power key, press and hold the Volume down key.
- Continue to hold the Volume down key until the device finishes restarting.
- Safe mode will display in the bottom left corner of the screen.
- Release the Volume down key when you see Safe Mode.
- Once on safe mode, try to charge the phone for at least 30 minutes and see what happens.
If your S10 charges fine, a bad app is a likely reason for it. To know which of your apps is causing the problem, follow the steps below:
- Boot to safe mode.
- Check for the problem.
- Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
- After you uninstall an app, restart the phone to normal mode and check for the problem.
- If your S10 is still problematic, repeat steps 1-4.
Factory reset. Wiping your device and reverting its settings to defaults may be drastic but it can be effective. In older Galaxy S phones (S7, S8, S9), some cases of moisture detected error requires a factory reset as the main cause was software glitch. If none of the suggested solutions has helped so far, don’t hesitate to factory reset your phone.
There are two methods to factory reset your device. Here’s each of them:
How to hard reset on Samsung Galaxy S10 via Settings Menu
- Create a backup of your personal data and remove your Google account.
- Open Settings app.
- Scroll to and tap General management.
- Tap Reset.
- Select Factory data reset from the given options.
- Read the information then tap Reset to continue.
- Tap Delete All to confirm action.
How to hard reset on Samsung Galaxy S10 using hardware buttons
- If possible, create a backup of your personal data ahead of time. If your problem prevents you from doing that, then simply skip this step.
- Also, you want to make sure that you remove your Google account. If your problem prevents you from doing that, then simply skip this step.
- Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
- Press and hold the Volume Up button, the Power button and the Bixby button at the same time.
- When you feel the device vibrate, release ONLY the Power button.
- A screen menu will now appear. When you see this, release the remaining buttons.
- Use the Volume Down button until you are highlighting ‘Delete all user data.’ Press the Power button to select.
- Press the Power button again to select the Yes – delete all user data option.
- Press the Power button to highlight, then select the Reboot option
Use wireless charging. The wireless charging capability of your device is not affected by a fault in the charging port. So, if nothing has worked so far, consider charging your device wirelessly. If you want to permanently fix the problem though, you should have the phone checked by Samsung so the port can be examined closely.
Clear data of USB Settings service. In some cases of moisture detected warning errors, the cause is not exactly a serious hardware issue but rather a USB port settings glitch. There had been rare cases of this problem in the past but factory reset did help. However, in case you want to check further, you can go ahead and the data of USB Settings app to see if it helps. Here’s what you can do:
- From the Home screen, swipe up on an empty spot to open the Apps tray.
- Tap Settings > Apps.
- Find and touch USB Settings.
- Tap Storage.
- Tap Clear data and then tap OK.
