I have two LG G6 phones, one for my wife and one for my son. My wife's phone is fine, but son getting moisture warning on his G6.

Is anybody else getting moisture warning on their G6?

Is he taking showers with the phone in the bathroom? Taking it swimming with him?

It's water-resistant (meaning if it gets wet, water probably won't get in. Steam gets in. Moving it around in a few feet of water can let water in), not waterproof.

1.5m of water is about 2.25 pounds of water pressure. Plunging the phone into 6" of water exceeds that. Placing it gently into a foot of water won't.

Tell him to consider the water-resistant rating to be insurance, not a waterproof guaranty.

At least, if it was steam from a shower, that's almost pure water, so drying the phone should leave it in fairly good condition (but tell him to leave it turned off for a few days in silica gel or dry uncooked rice).

I got a "moisture in the USB port" warning and the only resolution for me was to send my G6 back to LG for warranty repair. My phone was never near any water sources, BTW.

cohoman,

Do you know what did LG replace in your phone?

[cohoman]

They said they replaced the USB port to fix the problem.

The detection seems to be pretty sensitive and many of us have gotten the warning without actual water exposure. It had gotten to the point that I was starting to think there's a QC problem with the USB ports and we'd all be submitting warranty claims for them. That still may happen but I was eventually able to get mine to stop.

For many of us the answer is to properly clean out the port. First do a good mechanical cleaning to get rid of any conductive debris. Use a magnifier and light to make sure you get it all. Use something plastic so you don't damage the contacts. Compressed air probably won't do the trick.

Next you want to clean the contacts. Some people (not me) have had luck with rubbing alcohol alone, which will not only help clean, but drive off moisture. You can also find a plastic-safe electrical contact cleaner to use. Make sure you use some kind of tool where you can actually rub a pad of some kind against the contacts to clean them.

They make special electrical contact lubricants that are supposed to prevent corrosion and displace moisture. A little of that shouldn't hurt as long as it is plastic-safe.

Some people have had success taking out the sim tray and putting the phone in a warm place for a while in case any moisture (from humidity or sweat) did make it inside the phone.

Replacing the USB port might be necessary, but I really am hoping that in general it's not.
