I've been getting this "Moisture in charging port" message recently and after Googling the symptoms I was very discouraged because "fixes" did not seem to work. Phone would only charge wirelessly and my nexJack Dex would only work when the USB C was plugged in one orientation only, if at all.. Eventually I paid ubreakifix to replace the USB C charging port and the problem has gone away.
Why am I posting this you ask? Seems very straight-forward. However the ubreakifix tech said he found evidence of a PMC failure and some "electricity was leaking" and causing the battery to age faster and will cause other failure modes to the phone such as I was experiencing. I was/am skeptical because the only method he used was to plug some "special" equipment into the USB C port. He was confident that he didn't need to recheck after the port replacement.
Has anyone else encountered a PMC problem with their Note 8? There is actually a YouTube video of a PMC Note 8 replacement---not for the faint of heart.
Hi, test to clean data and cache on USB Setting (system application) and reboot.... It's OK for me now.

Actually I did this without any good result. Replaced the charging port and all is well for my case. Your case, of course, could be different.
Could be that the port is faulty...

Same happened to me few times, especially after going to swim and put my phone in my wet pockets, the solution was to plug the original charger (even with the message of moisture) and reboot. After the reboot the phone was able to charge via USB again, although I charge it wiresly most of the times.
I don't know but several persons helped that method, maybe just a software error.
I have the suspicion they're reading data from the phone, not directly from the hardware; and if that data is the result of a software issue (I'll get to that below), their voltage leak is a faulty assumption. My experience:
Same problem here. I tried a ton of fixes: new cables, new chargers, safe mode boot, USBDevice data wipe, Dalvik Cache wipe, full reset, etc. but none of them worked for me. Closest I got was holding down Bixby button on boot and then plugging in cable-- which would let me charge normally UNTIL I unplugged the first time; would always get moisture detected after that until next reboot....
Was ready to replace hardware at ubreakifix....
UNTIL I found this solution in a single obscure Youtube comment:
1. Reboot
2. Plug in cable on first logo
3. Unplug when 1st logo goes away
4. Quickly plug in again on 2nd logo.
It worked like a charm for me. Now I have no issues.
This confirms to me that there was some odd software flag that was tripped. My guess is that there's a baseline voltage the phone measures for charging, and when the voltage is under that baseline, it throws a moisture error. I bet this sequence causes the phone to measure a new baseline, thus resetting the bad data that tripped the moisture flag previously.
Just a guess, but would make sense.

So like many others, I have a AT&T Tilt, 8925 or HTC Kaiser that quit charging with some of my chargers. My symptoms were like everyone else. It will charge with a car adapter, or "X" brand of wall charger but for no reason just quit charging one day.
Here are the four charging methods I am using, and the different symptoms when this issue presented itself.
1. Wall A/C charger that came with the phone.
2. Car charger that I got from AT&T store.
3. USB cable plugged in to my laptop.
4. Wall A/C charger for "some other" device.
When I first got the phone, all of the above worked. Then after a few weeks, this happened.
Wall Charger
Still worked. No change.
Car Charger
Charging LED would not light up. Phone would not charge.
USB Cable
Charging LED would not light up, but I could Sync the phone with WMDM.
Wall Charger (other brand)
Charging LED would light up, but the phone would not charge.
So I went through and real a lot of posts and I first made sure I had "When device is turned on, do not charge the battery when connected to the PC" unchecked. This did not help.
Then I started looking closer to my phone. And I noticed what seemed to be one of the pins on the mini USB port was bent back in to the middle plastic piece that stands in the middle of the connector. When holding the phone face up, it was the pin to the far right. See my picture below. (I wish I had a before picture)
I removed the battery from my phone and used a small pick to VERY GENTLY pull the pin out a bit. I did my best to make it look like the other four pins to the left. You can also see in the picture, that the 4th pin is bent back a bit too but I left it alone. I did not think it was bent enough to cause a contact issue with the connector. After fixing this, I installed the battery and tested it out. And to my surprised, that fixed the problem.
So, the question is, how did this happen???
Well, I suspect it's from trying to stuff the stylus in to the reset button but missing and hitting the mini USB port instead. That middle "stand off" piece of plastic has some flex to it. So by stuffing the tip of the stylus in the corner of the USB port, that likely flexed that plastic back which also bent the pin. Note that the pins are not attached to the plastic piece, so that is why only one pin bent and not all of them.
Long winded sorry. But perhaps may help out.
And take this all at face value. This is just what was wrong with my phone. Mileage will vary.

Completely stock, no mods.
Woke the phone up this morning to check twitter, email etc.
All of a sudden, it gives the beep sound, "mtp initialization" sound, media scanning messages, then loops around and does it again and again and again.
The only way to stop it was to connect it to the charger. Once disconnected, it starts doing it again. Took out the battery, SIM, SD card. Left it sit without those for 5 min. Plugged it back in and a few minutes later it started doing it again.
Any ideas???
It's run all day today without an issue. Battery down to 72%. Just connected
it up via USB to charge it a bit.
Only thing I did was to remove the mSD card and blow some air around the SD card & slot.
Bad SD card????
I think it might be a bad USB port
If I bang it slightly against a desk (rubber case), it stops doing it.
Sometimes if I pull the battery & put it back in, the battery logo thingy
comes up, it won't power up for a few seconds, then it will.
I got this via Amazon...it's a German version (DBT).
Anyone know a USA location for warranty service?
ah its probably pucsed up. The phantom usb connection syndrom. We should partition for a usb hole cover from Samsung
You got lint/dust in there m8 use compressed air or a fine brush to clean. check if that solves it. I had to clean mine several times. Never even saw the dust in there myself.

Dust? That's interesting....that port IS open to the elements.
That does sound like what it is doing. It thinks I'm connecting/disconnecting
the cable. How would dust "short out" a connection?
I'll give it a blast of canned air. Any suggestions (removing the battery) on hitting
it with a brush & alcohol?
green stuff inside port
I took my loop & was looking inside the port and found what appeared to be
some greenish corrosion inside the port?
Found a closeup photo of a microusb port and painted in the area where the
green contamination was. I took out the battery & used a stiff non metallic
brush to clean it out, then hit it with a can of compressed air.
So far, it's behaving...

yeah, the dust I had was inside the phones usb jacket.
Corrosion, that sounds like issues people were having with sgs. Not a good sign. It shouldnt have that.
I got my info here
androidforums.com/samsung-galaxy-s/...stays-after-usb-disconnected.html#post1850661
I cleaned mine with a small dental brush, the ultra fine ones and nothing else. I didnt have to clean battery thought. best to power of unit thought wouldnt want to short it when brushing

That makes sense. Thanks for that link. The description from xphoneguy makes about as much sense as anything else. Especially his photos looked a lot like what I was seeing inside my usb port.
from the link you posted...
Why does this fix the problem? Well, I used to design cell phones, and I know a thing or two about the external connectors on phones. The phone has to have some way of detecting that something has been plugged into the connector. Micro USB connectors do not have a mechanical switch to detect the presence of a plug in the socket. If these connectors work the way USB OTG (On-The-Go) connectors work, there is a resistor in the cable between two of the pins. The phone attempts to pass a small amount of current through that resistor to detect the presence of the cable. When there is debris in the connector, like cotton fuzz from clothing, tiny bits of soap from washing, and tiny flakes of dead skin, and you add humidity from perspiration or rain, etc. you create little blobs of slightly conductive goo that can bridge the gap between the pins. That blob of goo looks just like a resistor to the electronics in the phone. So the phone thinks there's always something plugged into the connector. Why have some people been able to fix the problem with settings then? I suspect that they found settings that cause the phone to stop checking for a USB cable or to ignore the signal that tells the OS that something is plugged in.

So i accidently plugged in the usb the wrong way and the phone shut off. Have tried every button combination and holding down the powerbutton numerous times with no success. Led light doesn't light up and have tried leaving it in the charger for various hours and used different chargers. My next step was to disassemble the phone and hope a battery pull did the trick but that didn't work. However when I disconnect the black battery connector and plug in a usb the red led lights up for about 15 seconds and dissapears.
anyone know any possible solutions? I think my battery might have fried

Is there a way to jump the battery and hope that that works? I've jumped plenty of batteries on phones with removable batteries but I'm not sure if the Z has metal contacts for negative and positve
no one?
normally any device that has DC input (like usb) is secured with diodes so that even when a faulty charger is connected it doesn't fry. But that's my electrical knowledge speaking. Please reply when you found out what the problem is

My One X did fry when I connected it to a car charger not too long ago
still no luck on this phone however

Alright thx for the info but maybe you had another problem with you charger and the transformation from 12V to 5V was bad, that can't be controlled with only a diode. Or maybe your One X hadn't any security internally because the manufacturer wanted to save money on that component / no place anymore to put it in the phone.
Think I have something similar..... Connected to car charger, led didn't go red,pushed charger in moved wire in phone charger goes off, phone won't start tried all button combos.
Sad bit is I only just got phone 3 days ago:banghead::banghead::banghead::banghead::banghead:

No I don't see any damage to the USB port.
I did the same to my xperia Z1 (reverse biased it using usb and 5 volts wires) The battery however had charge so as soon as I connected the phone restarted and could not charge any more. Any solution please ????
Might be an old post but I had the same problem. I was fixing a cable (18V) and I wanted the range the cable in the corner. I was so lazy to use a screw driver or something else. So I used what I have in my hand: The jack cable, plugged into my phone. So I used the bare part of the cable (Don't ask me why, I don't know). I don't remember if my phone restarted, but he was fine. But not my jack connector. When I plug an earphone it says that my earphones are not recognized. So I change it (by my self) But still the same problem...
Seems like the problem comes from somewhere else.
do you found the fried parts of your phone or fixed it ?
i have same issue today i connected an experimental cable (v+ was placed into gnd pin and gnd to v+) to my lumia 625 and it flashes then shut off immediately now it show no sign of life not charging not turning on
anyone knows what parts have been fried ?
My Z3C's USB port has become unresponsive, it wont charge the phone nor connect to a computer.
The phone itself works as it should, apart from the USB.
It does sense that it is plugged into a charger when in an off state and boots into the battery charging screen however no charging takes place and there's no animation of the battery icon or change in the percentage. The magnetic charging port does work though.
I can't get my computer to recognise the phone in either standard mode, fastboot or flash. However when connected by USB I can get the phone into fastboot (steady blue) or flash mode (red/green flash), it's just my computer doesn't pick up anything.
I've tried several cables, chargers and computers so all that can be ruled out.
I've verified the continuity between the end of the USB port (that connects to the computer/charger) to the pins soldered to the main board of the phone. Everything seems fine. I reflowed the solder of the USB connector just to be sure.
I'm at a loss, anyone got any ideas?

if phone has warranty use it, i had this problem in some phones sometimes mic fails as well and I had to change usb flex for galaxy s2 and 3. Sometimes is for humidity on usb flex.
I've just been inspecting the mainboard closely near the usb port and I think there's a component missing. No idea how it has become detached.
The phone is an ebay salvage project, but I'm sure when I received it I could charge it fine through the USB port although it wasn't soon after that it started having problems. Now I'm doubting myself that it ever charged in the first place.
Anyway I'm now looking for a high res photo of the Z3C mainboard (battery side). I've got a dead Z1C with the same components near the USB port but as the components are arranged in a different orientation I'm unsure of which way round to solder it to the Z3C.

Hello, I currently have a note 4 marshmallow 6.0.1 but a few weeks ago before marshmallow got released the phone started charging really slow, it takes about 8 hours to fully charge, tried 3 different batteries, tried 3 different chargers and the issue persist. I tried to connect it to my computer to root it but it shows as unrecognized device, same goes for download mode (tried other computers too with the same result)
I thought it was the usb port so I ordered through ebay and replaced the usb board, it's still doing the same thing, takes about 8 hours to charge, is the fast charge capacitor/chip/controller on the daughter board or is it on the main board?
does anyone know if there is any other way to root the phone without odin as it's showing unrecognized on my pc?
Samsung devices are notorious for charging ports going bad.
Your charging port probably needs replaced fella. And as far as I know Odin is the only way to install TWRP since Towelroot has been patched back in the day.
@renickdp I have a note 4 as well.
I flashed Marshmallow and then a Note 5 port. Now I am having the same issues as you.
Extreme slow charging
(I use the app Ampere)
It's charging at a rate of 220mA
When normally it'll charge at 1020mA or 1700mA
It says I'm connected as a USB Charger, not AC (Which is wall)
Like you, I've tried 3 different power bricks, 4 different cables and 3 different batteries.
The thing that I find ultra werid is that this happened after flashing Marshmallow. I don't think it happened immediately for me but I honestly can't remember.
I am buying a new MicroUSB port and if it works after replacing it I'll tell you if not then this bug obviously has something to do with Marshmallow.
It happened for me about 2-3 days before marshmallow, already replaced the usb board and still the same issue, I'm starting to think is a device issue with the main board because even in download mode the computer shows unrecognized device
does anyone know if the power gets controlled by the usb board or the main board? I was looking at this picture and I was thinking the power management chip is what controls the fast charging and usb device identifier?

I don't know. But I have the same issue. I haven't yet replaced my usb board/port but Oh. I'm getting 250mA and below. At the max I'll get 350mA. What model do you have? What ROM / Firmware? (when the issue started)

I'm on stock it happened like 3 days before the OTA 6.0.1 that tmobile released, I updated OTA issue persists, model is the release one, not the newer T3
just received another usb board, will post back as soon I install it
I replaced the USB Port. Now the LCD screen is Broken! (I accidentally dropped it)
Soo.. I don't know if it works or not I'm going to end up getting a new phone most likely.
(I can't boot it into download mode. Not as of rn at least I haven't tried all that much but yea)
@renickdp
I'm sorry I couldn't be more help. It is an absolute pain rn.
I replaced the usb board again, same issue, on device manager on my pc I get a unable to get device descriptor, so I guess what controls the device usb must be defective on the main board
I will probably replace it but I need to do a backup I know I can backup the apk using different apps but, does anyone know any backup method that does not require root or a usb port and backups the app data?

I have the same issue with my Note 5. USB won't work for anything (Gear VR. OTG, Fast Charge) except slow charge. I changed the charging port and same issue. Can figure out what the issue is. Cant even flash firmware thru Odin as USB is not recognized.
used a brand new fast charge cable today that went hot and killed my USB going to check the cable for x'd cables latter on
( not happy )
swapped logic board to another frame to rule out daughter-board , so it must be a chip on the logic board I need to swap over , thankfully donor board around
no longer Trust these cables
