A moisture warning on a Samsung Galaxy® is one alert worth taking seriously—at least at first. But when the charging port has had plenty of time to dry and your phone is still refusing to charge, it’s fair to wonder what’s going on.
At Asurion, our experts know when a warning is doing its job and when something else may be keeping it around. Here’s how to safely clear a stubborn moisture detected warning and know when the charging port itself needs a closer look.
Why does my Samsung Galaxy say moisture detected?
If you get a Samsung Galaxy moisture detected warning, some liquid or debris has probably gotten into your USB-C charging port.
The warning doesn’t just let you know about the moisture. It can also temporarily disable wired charging, since plugging a cable into a wet USB-C port can cause more permanent damage. Your phone is trying to prevent short circuits and corrosion in the charging port.
Some reasons why the warning may appear include:
- Water or liquid in the port.
- Dirt or debris in the port.
- Corroded pins or damaged charging cables.
- Temporary software glitches.
Software glitches or corroded pins in your charging port can cause a false positive, leading you to see the moisture detected warning when there isn’t actually any liquid present.

How to fix the moisture detected warning on Samsung Galaxy
If you see the moisture detected warning, it’s best to assume there is liquid in the port. Take these actions as soon as possible to prevent damage.
Let the charging port dry
Shake your device gently with the charging port facing down to try to clear any trapped liquid. Then, leave your phone standing up with room underneath to air dry for at least a few hours. While there may still be moisture in the USB-C port, make sure you don’t plug your phone in to charge. Also avoid using a hair dryer or other external heat to dry the port, since this could overheat the device and force water farther in.
Check the charging port for debris
Look in your charging port to see if you can see any lint, dirt, or other debris that could interfere with charging or moisture detection. Gently use a wooden toothpick or other non-metal device to scrape out the debris if present.
Restart your Samsung Galaxy
If a temporary software glitch is causing the warning, simply restarting your device may be enough to get rid of it. After you make sure the charging port is dry, restart your device.
Clear the USB settings cache
If you still can’t get the alert to go away, try clearing the USB settings cache with these steps.
- Go to Settings > Apps > Filter and sort.
- Toggle on Show system apps and tap OK.
- Choose Storage under USB Settings and select Clear cache.
Update your phone and test another charger
Update your phone if there’s an update available to help clear any glitches. Also, try testing another compatible cable and charger to rule out software or accessory problems.
What if the moisture detected warning won't go away?
If you try these troubleshooting steps and the warning still won’t go away, there may be charging port damage rather than moisture or a software issue. Try charging your device with wireless charging if your device is compatible.
When does your Samsung charging port need repair?
Look for these other signs of a damaged charging port:
- Your charging cable feels loose when you plug it in.
- The base of the cable feels hot when plugged in.
- You can see rust or debris that can’t be removed in the port.
- There are bent internal pins in the USB-C port.
If you notice these signs of possible hardware damage, you may need to have the charging port professionally inspected and repaired.
