Hi everyone.Please help.My phone has never been near any moisture but when charging,I get a msg that there is moisture in the USB port.I can't charge my phone.I am very frustrated with this phone
Hi Pieter76 That’s a frustrating one, the moisture detected warning can appear on Samsung phones like the A55 even if the device hasn’t actually been wet. It’s usually caused by residual humidity, condensation, or a false sensor reading. Here’s a full step-by-step fix you can share (and try yourself if you’re testing for others on Samsung Members):

🔧 Fix Moisture Detected Warning on Samsung A55
1. Check and Dry the USB Port
Power off your phone.
Use a soft, dry cloth or cotton swab to gently wipe inside the USB-C port.
Do not blow directly into the port or use a hair dryer — that can worsen it.
Leave the phone in a cool, dry room for 30–60 minutes (not in sunlight).
> 💡 Tip: You can also put the phone upright near a fan to circulate air — avoid heat.

2. Clear Moisture Warning Cache
Sometimes the system falsely triggers this message due to cached data.
Go to Settings → Apps → USBSettings → Storage → Clear Cache & Clear Data
Restart your phone.

3. Try Safe Mode
This helps check if a third-party app is interfering.
Press and hold Power → tap and hold Power Off → select Safe Mode.
Try charging the phone. If it charges fine, then an app may be causing the detection error.

4. Charge Wirelessly (if available)
If your A55 supports wireless charging (depends on region), use a wireless charger until the issue clears up.
---
5. Override Only in Emergency (Temporarily)
If you’re certain the port is dry:
1. Turn the phone off completely.
2. Plug in the charger while the phone is off. It may charge slowly but bypasses the moisture detection temporarily.

6. Software Check
Make sure you’re on the latest version of One UI. Go to Settings → Software Update → Download and install. Occasionally, these warnings come from firmware glitches fixed in patches.

7. If All Else Fails
If the warning persists for more than a day, visit a Samsung Service Centre. It could be a damaged or sensitive USB port sensor that needs recalibration or replacement.
Used to happen to me a lot if my phone was either exposed to dust or I put it under my pillow when I sleep. Sometimes I would just blow into my charging port and it works immediately other times I found disabling fast charging solved the issue. It's not always moist, it could be just debris stuck in the port.
