Moisture Detected, Charging is blocked.

"I don’t normally work on LG phones but I did have an LG G6 come in the shop recently and I had exactly this problem following a microsoldering repair. I even used the suggestions in this Q&A so I’m happy to contribute back to LG users and experts :>).

Here are my results (which may vary as every phone and situation is unique).

I found tons of pocket lint inside the charge port. This is known to cause this error message as well but in my case, cleaning it out it didn’t solve the problem.I cleaned the port with 99% IPA. I wouldn’t recommend WD40 as the OP tried because while it’s great at removing moisture, it also leaves an oily residue. A bag of rice does nothing…compressed air would have been faster and more effective but in my case, there was no moisture inside the port, contrary to what the phone thinks.I tried activating USB Debugging mode in order to disable connection to the LG System Server —> didn’t helpI followed @povertyd suggestion. This worked partially, allowing me to charge the device but when I rebooted the device, it was back to the Moisture message again.Because I had worked on the phone, I did a thorough visual inspection under high magnification of the Charge Port Flex and the inside of the charge port itself. No damage to the pins, no (more) visible debris, no dislodged components next to the connectors.In the end, on a hunch, I tried a different USB-C cable and voila…that was it!

My only other option left before figuring out that it was the USB cable was to replace the Charge Port Flex (iFixit doesn’t seem to carry it so here is an alternative). They are inexpensive and relatively easy to replace."

"Ryan,

Generally when the port detects that there is moisture when it is no moisture it is solved by replacing the charging port.

You can follow this guide to replace the part.

I hope this helps,

My fix is very simple, now that I’ve discovered it. The charger connection can go either way up. If I plug it in one way, I get the moisture alarm; if I turn it over, it charges fine. Go figure!

Hi. I had to try several things, but what ultimately worked was restarting the phone WITHOUT REMOVING THE CHARGER . I left it connected to the phone, did a restart, and when my LG Venture phone came back on; it charged normally. Works everytime…hope it works for you!

Here’s how I fixed it and I don’t know why I didn’t see it before. Press on the notification when it pops up. Go to More Settings. Under Categories it will show the USB notification. There was a 3 dot menu indicator that I hadn’t seen before. Press it. Set notification to Low - no sound or text. That did it!

To be honest, I'm so !#^&@@ it has been this way for 4 days now. Nothing permanent works, but I did everything. I restarted my phone on off, i did the code thing didn't worked, I turned off the notif, I reset data for LG system server, now i tried 3 type-C usb cable, some.works then detects again, then another one you have to flip the side of the USB itself then it charges. Sometimes it gets full, some times it detects things likeeee this thing moisture fcking thing has mood swings and I'm sick of doing this, I tries cleaning, brush and removing dirt from inside. Nothing permanent works.
