Moisture/Debris Alert on S25 – Only Charging Wirelessly

[liselottep]

Hi everyone,

I'm having the same issue that many others have reported. I bought a Galaxy S25 about three months ago. For the past few weeks, I’ve been unable to charge it with a cable due to the persistent moisture/debris alert, so I’ve had to rely solely on wireless charging.

Here’s what I’ve tried so far:

• Dried out the charging port with cool air

• Swapped out different cables and chargers (including brand new ones)

• Used official Samsung cables and chargers

• Tried charging in Safe Mode

• Reset all settings via: Settings > General Management > Reset > Reset all settings

• Cleared USBSettings cache: Settings > Apps > Filter & Sort (Show System Apps) > USBSettings > Storage > Clear Cache

Interestingly, after a Samsung update a week or two ago, the issue temporarily disappeared and I was able to charge by cable again—but only for a few days. Then the alert returned. I’ve now installed the latest update from 1 June 2025, but the problem is still there, and I'm stuck with wireless charging only.

I also ran the Diagnostics tool, which simply told me: "Cable charging is not working."  

What’s even more curious: my husband, who has a different Samsung model, started having the same issue a few weeks after mine began. His issue also briefly resolved itself after a software update.

Is this a software bug? A hardware issue? Is anyone else still facing this even after the June update?

Would love to hear if anyone has a long-term fix. Thanks!

Contact Samsung support via Members app and let them deal with it

I have now done this: "Hold the Power button and volume down for 15 seconds to force a power off. It's like pulling the plug on a computer"

as suggested by @arianwen27 and this seems to have solved it, for now!

Unfortunately, the problem started again today. Despite doing a force power off 😪

I had similar problems after purchasing a new charger with my 8 week old S25. Brought it to the Samsung Shop and they told me it was a faulty charging port caused by using an old cable 😲. Changed the port and now working normally. I did have the Moisture warning come up before the change but that was only with the cable I use in my car. Strange one 🤔

Its the ui 7 update, send a bug report through the app, ive tried to report this to samsung but despite reports online ui 7 is causing issues with existing devices they dont believe me lol

Yup I was getting the moisture issue too. Now my phone won't charge via cable unless I put the cable in a specific orientation. It didn't start until I updated to the June 1st update about a week ago. I've tried 6 different cables, clearing the USB Cache, etc. It's 100% a software update issue with the USB port, but good to know its something they can presumably fix if we keep reporting it.
