Chosen Solution

Help! I have a three weeks old Galaxy S9+ and the notification of moisture detected at the USB charging port is keeping me from charging my phone and keeps alerting about the moisture. I live in Michigan so it’s not overly humid. This past weekend, it was rainy and humid and the darn phone wouldn’t let me plug in the fast charger. I didn’t have my wireless charger with me. Is there something wrong with the phone? Should I return it to Best Buy and ask for an exchange or refund? Help I am conflicted. (By the way I switched from an iPhone 8 for a change of pace.)

Hey guys had this problem myself and after months of playing around with it I found a solution. Buy a wireless charger and get enough charge on it to atleast be able to get into settings (2-3% would be enough)GO into settings and into battery usageScroll down to ‘Recent Battery Usage’ and find the app ‘Android System’Tap on that and then tap on ‘Force Stop’. It had a warning that doing that could cause system problems but all it did was take away the ‘Detecting Moisture’ notification and I was able to charge again. If you can get passed that I recommend getting a new cable, I went and bought a better one after fixing it and things were sorted. Good luck

There is actually an easy workaround to that error! Just turn your phone off, connect the charger, and then power the phone on. It shouldn’t give you that error when you do that.

Use Android System Recovery Option to bypass Moisture detected at 0% charge. When phone is at 0% and it shuts down, the moisture detected error doesn’t let the phone charge even if left plugged in for hours. The screen shows 0% always. However, the phone charges if it can be turned on till home screen. So I tried a method and it worked for me:

  1. Let the charger be plugged in the phone. 2.  Press & hold these buttons together: power + volume up + Bixby
  2. Android logo will be displayed. Installing system update will show.
  3. Press the volume down key several times to enter android system recovery option screen. 5. When you arrive at recovery option screen, Leave it as it is for 10 to 15 minutes. The phone will charge to 5 to 10%.
  4. Select “reboot system now” (use volume up/down button|) and press the power button. The phone will restart and you will see the full screen and charge %. From there on you can keep charging without the annoying message.

You could have dirty contacts in the charging port. I work in a very dusty paper mill and I’ll get a moisture warning when the charging port gets dirty. Use 90% isopropyl alcohol or electronic parts cleaner and a toothbrush to clean the port. Then blow it out with canned air if you can.

I found a easy solution to this. First go into safe mode and find out if its a hardware or software problem. Restart phone, press both volume and power buttons while its restarting to get there. While in safe mode try the charger. If you get the same $@$* its the hardware, so theres some kind of moisture dmg. Follow the drying instructions. If it goes away then its something in the software or operating system. Luckily i found a quick easy fix. Boot phone normally and just goto setting and use the device maintenance option. This should fix the problems if its a usb cache or memory error. If problem persists you might have to wipe the storage/disc partition or try clearing cache manually. The details for this you can find easily with a google search. Just type (phone model here) wipe partition OR wipe cache Allright, hope this helps guys.

On a Galaxy S8 I tried all the ideas presented in this thread but nothing worked. Finally the only method I found was to power-off the phone, then power-on without the charging cable connected (it does not start otherwise), then immediately after the logo is shown on the screen, plug the charging cable. There is no more moisture error after that and I could get normal charging (fast charging is not working in this way for some reason). Removing the cable and plugging it back in gives the same moisture error so for a recharge I need to start over with the power-off -> power-on cycle.

I tried the following: Turn off the phone Hold Power Button + Volume Down button until the android icon shows Then put power cable back in (still holding the buttons) Wait about 5 seconds then release the Power & Volume down button Battery is now charging in fast mode Found this solution on another forum - hope it works for you

I am a electronic technician and Java Software Programmer with 24 years, so I attempted all suggestions in here and did even many other “tricks” but NOTHING worked. I am convinced it was NOT a HARDWARE problem. So I suspected it was a software issue, a misbehaving app? virus? OS/firmware corrupted? or something like that so….. I reset to factory reset and now all is working fine. Unfortunatedly, I lost many files but restore about 80% succesfully thanks to two things: #1. Google acccount backup in the cloud AND #2. I setup a SAMSUNG account with SAMSUNG backup and I restore many files but not all of them. I should had added my download folder to the Google Drive auto backup but I never set that up! In any case the phone works perfectly fine now, which confirms beyond any doubt that it was NOT a hardware problem but a SOFTWARE issue.

I experienced the moisture indicator problem on my customer’s Note 10 Plus. She was positive that it had not been exposed to moisture. I tried all of the non-invasive methods mentioned in previous posts, with no benefit. Through process of elimination, I concluded that there was a failure of the moisture sensor on the charging port board. So I replaced it, making sure to perfectly match the model number on the board with that of the phone. (This is extremely important as a slight mismatch will result in the device going into a semi-airplane mode.) Problem resolved. In this instance the issue was physical, not a defect in Samsung’s programming or software.

s9: after a couple weeks of wireless charging i gave up on this and got an s22. since all was lost i decided to leave it connected regardless of the warning. with the phone powered off it showed a warning icon but didn’t beep or anything, and seemed to be charging. after a while charging and unplug+plug again eventually the warning sign went away, now it seems to be happily charging.Turned the phone back on and now its charging and not complaining. Let’s see how long this lasts! I don’t suggest doing this unless you’re out of options. If it’s actually wet and you ignore it it may damage the phone (mine was definitely not wet, possibly was damaged but doesn’t seem like it). Unfortunately it’s too late to return the new phone. I don’t think s9->s22 is worth the cost delta.

This is a known software issue, no fix as of 9/7/2022. Assuming zero moisture exposure, shut phone down, plug charger in, reboot phone. It takes a minute but error will clear. This has saved my S9 every time. I have noticed if my charger is plugged in but not charging, it throws this error. Confirmed nothing wrong with charging cord. If phone battery is dead you will need to charge wirelessly to around 10% before attempting reboot. Also if phone is HOT allow to cool a bit first.

Tried some of the methods mentioned and could not get it to work. However , what got the job done was going into usb settings and force stop it.To enter usb settings, Go to settingsGo to appsGo to filter and sort icon and activate the show system appsEither scroll down and find usb settings or search it using filter at the topPress on the force stop at the bottom I hope this may help you in facing the same problem. If the same problem happens again, i will try to find a way and will post it here again.

Had this issue for over 24hrs and the solution that worked for me is as follows:

  1. If your phone hasn’t died yet, switch off your phone.
  2. Obtain a can of Abro Circuit Cleaner. (should be available at your local hardware store)
  3. Spray once directly into the charging port.
  4. Use something thin like a sim card tray key to guide a dry, static free cloth into the spaces between the charging pin to remove any excess Circuit Cleaner. OR Use a can of compressed air to blow out any excess Circuit Cleaner.
  5. The notification should be removed and charging resumed as usual. I hope this helps!

I had this issue on a Samsung A52s 5G phone and even after doing all of the things here, plus those of other sites, the problem remained. What worked for me was using an alcohol wipe/pad on the phone charging port and then going to my car and blowing the AC air into the port to dry it out properly. This fixed the problem for me. I am pretty careful with my phone so know it was was never immersed in any fluid so assume it must be from the high humidity as I live in Indonesia. Hope this can help someone as it took me a while to get rid of the annoying tone assosiated with the fault.
