Moisture Detected, Charging is blocked.

Hi, my father has an LG G6, and it has been saying moisture detected and prevented the device from charging. We have tried MANY things, putting it in a bag of rice even though he knew he didn't drop it in water or anything, using compressed air, rubbing alcohol in the port, WD40, EVERYTHING we could find online. But we have heard you can shut off the moisture detection, BUT all the videos we find are of different carriers "secret menu codes" so we can't figure it out. We have sprint, any help we can get? This seems to be a very common issue with the G6. I personally NEVER buy LG phones, because I know all the issues they have had in the past and present.

Same problem, started roughly the same time. I feel like im doing damage performing all these recommended cleanings. This "feature" needs to be removed or have that option. LG should not have the right to block my ability to use the phone because their equipment thinks there is moisture...

You can try this

*#546368#*930# ----> SVC Menu ---> Moisture Detect Setting ---> Disable

Replace 930 with your G6 model number. Mine was 873 and I turned it off. I'll have to test it later to see if I still get the message. Alternatively, what other thing worked for me was switching around the usb type c end that goes in the phone to the smooth side facing up. The connected side always sets off the message

model number is 988. I get a message "your call cannot be completed as dialed".

さんによる

I did manage to change the settimg to disable and it still gives me the moisture detected warnings

さんによる

Try removing the sim card and then sliding the slot back in. I tried that and then my LG G6 started charging.

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 help
  • I 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.

The part is availible online, for example here is one from amazon.

I hope this helps,

I legit just did this, and it worked: Take a lighter and light it. GENTLY wave the flame back and forth in front of the charge port for about 5 seconds (might take longer, I just didn't have to do it for very long). After that, I plugged my phone into the charger and it's charging great now! Hope this helps!

I know this might seem drastic, but hey, whatever works.

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!

Charger cable plug in “smooth" side up. It fits the other way too BUT then that's when the error occurs.

I hope this works for everyone.

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!

In SVC menu I disabled moisture detection and enabled it and it hasn't said moisture detected yet it's only been a few minutes but it worked so far

さんによる

Where is my SVC menu I can't find anything like that in my phone

さんによる

I fixed the same problem on my phone. When usb sign caming up in notification bar pull it down to read notification "moisture in usb port detected". Then pull that note to the right half way and tap "Settings" button.. While in LG system settings change priority for "moisture in usb port..." from highest to lowest priority. Done.

No annoying notifications since I did it. And yes, now the phone is charging through the USB port. However I'm not sure what's going to happen if you will get real water in usb port and not system malfunction.  If you do it, you do it at your own risk. Good luck.

I had the same problem. I deleted my cache files and restarted my LG6 and the moisture warning went away.

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.

Sorry for my English, I'm Brazilian using a translator, my solution briefly (not permanently) was to turn off the phone in safe mode, holding the on and off button, and pressing It on the screen you will see security option

AIt will restart cellphone, you can connect cable when cellphone is on home screen, it won't get moisture alert

But if you remove the cable it will come back, so you will have to go back to normal mode, do this to charge your device, then go back to normal mode through notifications

It's not permanent but better than breaking your head.
