Helloall ...I recently had the problem start at work sitting on my wireless desk charger. Got the moisture symbol and when I got home the constant noise. Tried lots of cables, turning off, etc. No joy. So I tried device maintenance in setting, meaning all the battery and other junk, turned off all background programs. I then took a small peice of tissue, thin tshirt material over the charging port and plugged in my charger, cleaned my charging port. This cleaned off small amounts of dirt/debris and the moisture symbol and noise went away. We shall see if this lasts. So far so good over night.
Hello everyone. This problem started to happen to me after i immersed my phone in salty water....into the sea. Nothing worked but AFTER I WASHED THE CHARGING PORT WITH NORMAL WATER ( thinking like washing the salt away) everything worked fine
I have been having issues with my GS9+ saying this for almost a freaking week now! Started with the last system update. It was charging on a cord and got to 97% and then woke me up with the stupid beeping from the warning! It was NOT actual moisture. This is such a life saver! Thank you!
I've had this issue several times also. Turning off phone does not work. I needed to dry port with hair dryer, AND store overnight in a sealed tupperware filled with rice. You're right, very annoying.
Some of these posts are funny you shouldn't have this issue at all! I am on hollidays in the phillipines a very humid enviroment i am here for 5 weeks the only thing i can do to get past it is disconnect the charger reboot then when the samsung sign has scrawled across the screen in full insert the charger that works for me i have tryed rice hairdryer that didnt help me i will be blasting my provider when i get home hope this works for you!
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.
Firstly though I went into settings .device apps,usb settings then clear cache, to make sure it was not phone.,it wasn't,t, it was minute moisture as phone was in my pocket , probably upside down, and I got wet walking in
I can bypass the issue by plugging in the charger while it is booting up. Regardless Samsung needs to fix this issue. I am afraid if I send in my device they will tell me I am at fault even though I know my tablet never came into contact with water....
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
Ι've had the same problem with my samsung galaxy s7 edge. It's supposed to be waterproof, so last night when I had a beach party and my phone slipped off my hand and got dirt all over it, I put it's charging port into the sea. I didn't really think of it until I came home and the detector kept going off. I didn't do anything then, but today, I rinsed it off with clean water and used a toothbrush and a swab to clean the dirt off. I used a blow dryer to its lowest level and blow dried the water off. The problem was solved.
Was having this issue after a recent Android update. Clearing the cache for the Android System fixed it. Go to Settings > Apps. Tap the ..., Choose show system apps. Tap Android System, then tap Storage > Clear Cache.
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.
This is the only trick that fixed my problem. I was so frustrated that I actually bought a S23. But I kept my S10 because I liked it more than the new phone. I will be returning the S23 in the morning. Thanks Colin... you saved me $1,200.
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.
That didn't work for me, but getting the phone into safe mode worked. Then I could plug it in to charge. To do that, turn off the phone. After a 20 second break, you press both the volume up and power on buttons at the same time till the Android sign appears. Then with one finger still holding down the power button, you press the volume down button several times, and the phone will say safe mode. Then you can charge it with no message.
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:
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.
I wanted to put a comment up . I had same issue on two of my phones my s9 plus . And then my husband gave me his note 10 plus when he upgraded I thought yes I can finally charge via a cable .. 2 weeks later moisture alert.. I was gutted. I took the phone to a phone repair shop as I was not letting this damm moisture alert beat me. 40 and its fixed. My last phone was my sons and he was bad for knocking the phone when then phone was plugged into charger and my husbands note 10 plus was on his motorbike on a charger so the vibrations had caused a wire on a board to come loose causing the phone the think there was water in the charger port or dirt.. Its a simple fix but I would recommend just taking your phone to a repair shop. I have had no issues with my note 10 plus since.
The trick is to get a corner of the the cleaning cloth damp with the isopropyl alcohol, put that corner over the port then use the sim tray remover point to gently push the cloth into either side - and move gently back and forward a few times. You want the cloth to "fold" so the point is enclosing the sim tray remover point - it will be a little bit tight, that's what you want - be gentle with it!
I have a galaxy z fold3 and have the moisture issue. None of the above solutions have worked. I also replaced the charger port and the error did not vanish. I have tried all recommendations out there and believe it must be a software issue. It's not an app issue as everything checks out ok in safe mode.
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 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.
