Moisture in port? Phone 2 months old

[Members_wcFJtHb]

Hi All 

I hope someone can help.

I purchased the new Galaxy S25+ on 7 April 2025, and recently I have started receiving repeated alerts stating: "We've detected moisture or foreign material in the charging/USB port."

This seems unusual and concerning, especially considering the phone is only about two months old. I can confirm that the device has not come into contact with water or any foreign materials, and the port appears completely clean and dry.

I have not been able to charge it with a cable due to the persistent moisture/debris alert, so I am relying solely on wireless charging.

Could you please advise on what might be causing this alert and how it can be resolved? I would also also appreciate knowing if this might be a known issue?

Thanks 

Helen

As is mentioned in the link provided by the above user, sometimes that warning appears because of dust/dirt inside the port, not only moisture. Maybe a cleaning would help. But be careful to do not damage the port. I used to get that notification on my old S8+. That phone did get water along the years but the warning would pop up randomly. I could charge it if I inserted the cable while the phone was booting. Then it would charge normally but then as soon as I would pull the charger out the warning would show up again. I've done that for months until 1 day the warning dissappear. But my phone was old and beaten. It wouldn't have been a big loss if it would've stopped working. So I wouldn't advise doing the charger trick on a 2 months old phone.
Now I remember that my mother's S23U did that as well 1 year after purchase for a few days. But she charged it "forcefully" with the method described a few times and then the notification dissappear. But I also know people for whom that method didn't work and the phone didn't charge. I just told you my experience with this issues. You're trying this workaround on your own risk. And better go to a service given that it still has warranty.

Hi Andrew - tried everything in the troubleshooting guide, tried all charging cables, samsung, anker, etc.  As soon as put the USB in the port it comes up with the error.  Its clean and dry so I really dont know whats going on here.  It charges wirelessy no problem, but I should be able to charge using the port too.

Return it to where it was purchased and ask for a refund or replacement. These phones are not cheap and you shouldn't have to put up with this

Did you upgrade to ui 7? There's numerous reports online of usb functionality breaking after this update. Its killed my wife's s24 ultra usb port as a result.

I think I have the funniest issue. I was getting the moisture detection but that went away. Now I can't charge without having the USB cable in a specific orientation. Its USB-C! I shouldn't have to flip the cable 😭🤣 I hope they fix this soon because it's annoying.

I have the same problem! Its super annoying. Usb cable only works when flipped into the right position. And as of today cannot connect a usb cable at all without debris / moisture. Phone is under 2 months old! Hope this really is just a software thing, I really dont want to have to replace / abandon Samsung.
