Fast Charging Not Working Properly After Moisture Alert (Samsung M34)

[Lucifer09]

Hey everyone,

I’m using a Samsung Galaxy M34. Recently, after recording a video in the rain, my phone showed moisture in the charging port. I left it powered off overnight and cleaned the port gently (no liquid used, only cotton).

Now the issue is strange:

When I plug in my original Samsung fast charger, the phone shows "Fast Charging" for 2–3 seconds

But then, charging drops to 0W (confirmed via AccuBattery)

After a few seconds, it even disconnects charging completely

In normal mode, it charges very slowly — it takes about 2 hours to reach 80%, which is not normal

I’ve tried:

Cleaning the port carefully

Using Safe Mode

Using different Samsung cable and adapter

Restarting and toggling fast charging setting

Still, the problem remains.

Is there a way to reset the charging/moisture detection sensor manually?

Or does this require a visit to the service center to reset/clean the USB port?

Any help would be appreciated 🙏

Thanks!

For 1 to 2 days, dry it in sun for few hours......
Your phone will be okay

Put your display opposite to the sun rays


I have tried and it worked
