![]() ![]() A sharp sliver of stiff plastic might be safer. You do not want to scratch or damage the USB contacts. With small pointed tweezers carefully probe inside port, removing any obvious debris. And the procedure below appears to have fixed a phone that's suffered for months with this problem. I had the moisture alert a couple days ago while I was camping, and there was legit moisture, and it went away soon after without another application of CRC QD contact cleaner.Ī follow up on this, and a thanks to /u/Darxus for pointing me in the right direction. And CRC QD contact cleaner seems to be an effective solution for me.Įdit, 3 months after posting: Since my last update two months ago, I've had no problems. So I don't recommend the CRC electrical lubricant. I am very disappointed, I really thought I had this.Įdit, 1 month after posting: Last time I believe I just re-sprayed with the CRC QD contact cleaner, and haven't had a problem since. Even though I've been mostly inductively charging, and there's nothing currently plugged in. Although I may have only inductively charged since last spraying.Įdit, 17 days after posting: Moisture detected in the USB port again. I taped over the speaker and mic, to prevent gunking them up.Įdit, 15 days after posting: No further problems. But I just sprayed it with CRC electrical silicone lubricant, which I expect to last longer. And I continue to suspect that spraying with the CRC electrical silicone lubricant I have will prevent it for longer.Įdit, 10 days after posting: The last problem was, as expected, quickly solved by re-spraying with CRC QD, and letting it dry overnight. And I'm a little happy to have ended up with a solution that left moisture detection intact.Įdit, 6 days later: I just noticed my phone, which is not plugged in, saying "Moisture has been detected from the USB port." I expect this will be easy to deal with the same way. It's such a huge relief to be done with this problem. I wouldn't recommend using anything metal for this, out of concern for damaging the contacts. Killing the LG system server: Go into your settings > apps and notifications > apps info > click the 3 dots top right corner > click show system > scroll all way to lg system server > click on it and then click force stop. (Warning that this will reboot your phone immediately.) I went back to that menu and verified that the setting saved, but it did freaking nothing. Scrubbing the port with 91% isopropyl alcohol and a toothbrush.ĭisabling moisture detection via typing: *#546368#*model#replacing "model" with your model number - mine is 872,into the dial pad, going to the service menu, and disabling moisture detection. Scrubbing the port with 91% isopropyl alcohol and a toothpick and bits of paper towel. I tried everything, and none of it worked. I stopped being able to charge my phone with a USB cable some time ago, and got to the point where my phone was beeping about moisture every 5 minutes even when it was unplugged. I think CRC 2-26 or CRC electrical silicone lubricant might be good for preventing this problem from returning. There is some possibility that my previous cleaning attempts were important. And then I left it unplugged overnight to give the solvents a chance to thoroughly evaporate. But I waited, because I knew so many times, these solutions have not lasted. I thoroughly sprayed my USB port with this stuff, and the problem immediately went away, and I wanted to tell the world. I picked mine up at Home Depot for $7.98. I got the idea from jdock in this thread: ![]()
