How to stop the annoying moisture detected at the USB charging port.

"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.

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.

"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

3. Android logo will be displayed. Installing system update will show.

4. 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%.

6. 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."

"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."

I had the same problem for months on my Note 9, tried everything you can find to fix it online, even had it diagnosed as having a bad charging port that needed replaced by a Samsung certified repair facility. Thank God I didn't go through with it. I use wireless charging everywhere. A couple places in my house, at my desk at work and in my car. So I honestly never needed to charge through the cable. But the fact that I couldn't hook my phone up to my laptop to transfer files or anything where I would need to hook to my pc (ADB, etc) irritated me. Back in June my phone had an update, not the One UI update, got that a while back, but some “bug fixes and security" update (6/14/20). Since that update my phone has been working perfectly. Glad I didn't fork up the cash for the charge port replacement! I feel bad for those that did and were also told that was needed to fix the problem! Pretty shady if you ask me. All good now though…
