Moisture in the USB port detected... help - LG G7 ThinQ Questions & Answers

Hello,
Yesterday out of nowhere i received this Message: Moisture has been detected from the USB Port."
My phone wasn't exposed to water, it was laying on the table.
When i switch the phone sometimes it disappears for couple of minutes but it comes again.
I Tried Blow drying the USB Port
Scraping with alcohol, tooth pick
Cache erasing
System message force stopping
It still reapers
I read that the G6 had also this kind of Problems. I assume this is a software Problem.
Does any of u faced this Problem?

You might want to contact LG to get it fixed.

I had the same issue with my LG G7, i ran the phone without a case for a week and left the SIM card/SD card slot open during the night , the message stopped appearing after that week. I had the same issue with my G6. I never got water near them and i had that issue, my roomates G6 had the same problem too.

I got the same issue but I was bringing it to the shower. It was annoying till I found that running the phone under water and drying it work.

I tried wiping it one more Time realy good with Alcohol also the usn connectors and the small corners between the Port and the case. Dried one more time with Dryer. Still got the error. Then the SOLUTION was for me to Restart it and while he was booting up to plug the charger and it disappeared.

Try blowing with compressed air the usb c port... Or sucking with a vacuum cleaner...

Option 1) Do you have a casing with a magnet in it, or any other magnets (wallet, bag, etcetera) (dunno for sure if the SGS2 has magnet-activated-carmode as well...?)
Option 2) Shortage in your usb connector? - does it charge correctly, does it connect well to your pc?
Thanks for the answer.
I have no magnet nearby. So that cant be the problem
it has happened a few times that it dont sync with the comp its just starts to charge the battery instead.
When i charge the phone. There is no problem.
first post, reading allot
i have this problem to, since a few days.
wiped al data. moved to stock firmware, but the problem is still there.
also causing extreme battery heat and drain from 60% to 0 in like 15 minutes
had adw launcer installed for a week or 2 but no problems.
it seems to me when you wipe all data this cant be a problem anymore.
will try diffrent firmware now.
if anyone has a solution for this problem please post
Anyone sorted this? Mine started doing the same a few days ago. Really annoying...?
I just noticed my SGS2 doing the exactly same thing today! I'm fairly sure it is related to dirt or dust in the microUSB port, since my friend dropped my phone at the beach (not gonna borrow it to him again!) and it got covered in sand. Few hours later, sporadic car and PC modes, sometimes the phone even thinks it's charging. I tried blowing into the USB jack but to no avail... I hope I won't have to return it!!
I think there might be bad microUSB port soldering. Try connecting your phone to pc and wave/move your phone, or tick the cable with your finger. Does it sometimes looses connection and reconnects right after (might not happen every time)?
Bad port soldering does happen for other phones too. But I'm not sure if this will be covered by the warranty. Service might say that you bend the cable/port too much when connected or something.
Anyone tried to bring the phone for the service because of this issue already? If this is the case service should be able to fix it easily.
Last night my phone wouldn't even start charging, so I decided to take matters into my own hands. With the smallest screwdriver I could find, I carefully 'lifted' the tiny PCB in the USB jack while blowing in at the same time. Sure enough, some sand particles fell out, and I haven't gotten carmode'd in nearly 13 hours now. Previously it would do it once every 15 minutes. So far so good, it seems.

I'm absolutely certain the warranty would cover this fault, if I pay $675 for a mobile phone I definitely don't expect it to stop working after I insert the USB cable the wrong way!

Thats why I think its soldiering problem. I did the same thing at it helped for some time, then it started vlingo again a few times, then again is ok for several days.
Does your phone do reconnects to PC when moved? It happens for me from time to time and it is scary that for example ROM flashing can get interrupted.

Yes, it did that once or twice, but I thought it was due to the fact that I was trying to remove other USB cables from my computer and accidentally hit the SGS2 cable. If it is actually a problem with the phone, it could actually be dangerous to flash a new ROM!
What we learned so far:
Problem:
1) Vlingo (car mode) starts sporadically (most often when connecting USB).
2) Phone shows "charging" or just "USB connected" even when it is not connected.
3) Sometimes starts "kies mode" without cable if "USB debug" is not enabled.
4) When connecting USB to PC, phone reconnects if moved.
5) Sometimes charging do not start when connecting USB.
6) Sometimes when trying to reboot, battery image with thermometer appears and phone do not start to boot when power button is pressed. It will boot into recovery (Vol Up + Home + Power). Go to the recovery and reboot from there. t
Reason:
USB got polluted or bended. It also happens if you forced to connect USB cable upside down. My guess is that soldiering of USB PCB gets damaged.
Solution (at least makes it happen less often):
Shutdown the phone, take the battery off. Clean the usb port. If it doesn't help then carefully bend the usb PCB a bit downwards.
If anyone brought his phone for service with this problem, please let us know the outcome.
Edit:
stevee1953 got his phone replaced because of similar issue: http://forum.xda-developers.com/showpost.php?p=15925236&postcount=7
Anyone fund a proper solution for above problem?
EDIT:
I cleaned the USB port with a toothbrush, and the problem is gone.
After cleaning the the usb and bending back the usb problem never appeared again so far (almost a month).
Hi all,
had the same problem (starting Car mode). After reading that some of your guys think it has something to do with dust, smut, etc. I remember my jogging during heavy rain.
I`m absolutely sure, that was my reason for the behavior. The usb connector has been wet.
After some hours (it was dry), i never see the problem again.
So be careful with your usb connector.
Tregobad
I've cleaned out the USB port a bit, and the problem isn't as bad now.
Still happens a bit though.
Just to be sure, people say to bend the USB PCB down? To me, it seems like it's very close to making contact with the bottom of the port, so I lifted it up (by putting a thin flathead screwdriver between the PCB and the bottom of the port to lift it up).
Is this right? Or should I be pressing it down even closer to the bottom of the port?
(I'm saying up = towards the screen, just to make sure )
Got the same problem, I wrote it down here:

Sometimes bending is needed, because this problem will occur if you accidentally plug USB cable upside down or have bend it with cable. USB PCB has to be very near bottom of the socket.
In your case you probably just need to clean it. What I did, I took a matchstick, sharpened it with a knife, then crushed the end (I did with my teeth ), so you get like a small brush. Then I carefully cleared socked with it (might need to make a few, but matchsticks are cheap here )
Be sure to take of the battery before cleaning, because if you just turn off, cleaning USB with something wet will make your phone to boot.
I'm posting my solution in a couple of threads hoping to help somebody out. This problem was driving me crazy:
I fixed it on my phone:
Reading http://forum.xda-developers.com/showthread.php?t=1132588 gave me the idea of cleaning the microUSB port. Of course with the battery removed. I also saw someone having the same problem with a HTC-phone so i guessed it couldn't be a software issue.
I used a non-conducting spray for cleaning electrical wiring (ask for Contact Cleaner), that removes oxidation from electrical contacts and such. I guess one could use Isopropyl Alcohol (from a pharmacy) as well, but i think the contact cleaner is better at removing oxide (reminds me of a less oily wd40).
I used a sharpened toothpick (soaked in spray) to clean the microUSB port but i guess you could soak something like small brush as well (toothbrush?). Once cleaned i let a small droplet fall inside just for good measure.
After a couple of minutes letting the liquid evaporate, i booted my phone to see the bug completely GONE.
The phone has not been in direct contact with water, more than regular humidity, and once or twice in the bathroom while i took a shower. This proves to me that regular use could in fact produce this bug by messing up the microUSB port. And that Galaxy S had an excellent solution by providing a sliding cover.

[SOLVED!](Q) Help! Phone showing it's charging when unplugged...

Since this morning my phone says it's charging when in fact it's unplugged. I tried cleaning the charging port, wiping cache, full wiping and reinstalling the rom, everything and don't understand why it'll never get off charging state.
I do check in settings while unplugged it says not charging and when plugged in says charging, but it's stuck saying "on battery for 23 min" and the icon never stops from charging....
Any suggestions? It's really annoying... Never had a single problem with my One S...
SOLUTION: Clean the charger port with a hard pointed object (that's what she said), make sure you clean and dirt or particles from underneath the middle piece in the charger port.
Also, if you notice the middle piece is too close or making contact with the bottom, use the pointed object to CAREFULLY bend it up a little.
Do all this while the phone is off and battery out. Use compressed air if available. if you wet it then completely dry it before putting the battery back in.
did you try wiping the Dalvik cache when you did the regular cache?

A LOT of users have reported this problem, yet Samsung claims it is water damage and won't do a warranty repair: http://www.reddit.com/r/GalaxyNexus/comments/tqlii/samsung_refusing_to_honor_warranty_for_infamous/
There is already a thread on this which has some useful info:
http://forum.xda-developers.com/showthread.php?t=1427539It ranges from yep your charging port is f*cked or it just needs a clean and little tweak.
To get mine fixed I gave it blast with compressed air and a little needle to make sure all the lint/gunk was out of the port. I made sure the port was straight (if it looks like it is bent downwards slightly, try and pop it back up softly). Then what fixed it for me is to hit it with a little electrical contact cleaner.
I have a feeling the port was getting shorted by something as each of the pins on the microusb port are very close.
Hope that helps
Interesting - I'll have to keep an eye out for something like this on my phone.
I guess first step is the compressed air blast with a needle cleaning of the port. If that doesn't work then on to Samsung to see if they'll honor a warranty repair (outlook not good on this - apparently they claim water damage). Worst case you can get a replacement OEM charging cable off ebay:
http://www.ebay.com/itm/OEM-Charge-...440?pt=LH_DefaultDomain_0&hash=item33746d1eb8
And fix the faulty part yourself or have someone you trust do it.
[EDIT] here's a link to ifixit for step by step instructions on how to take your phone apart http://www.ifixit.com/Teardown/Samsung-Galaxy-Nexus-Teardown/7182/1#.T7pzI8XdOII
Thanks to all the suggestions, it does the same thing even after wiping, installing other roms or going back to stock. I tried cleaning it with a toothbrush but will try with a toothpick or something stronger. Will give updates once I do.
I would suggest the electrical contact cleaner is going to be a good bet too. If it is water damage, it could just be a bit of water has gotten in there (from a table, rain etc) and then when its dried impurities could be shorting the plug.
I am not sure what stores in the states have it (maybe bestbuy?), but we have an electronic store here called Jaycar which sells it. You could even just slip in and give it a quick spray in the isle.
Turn the phone off before doing it, and make sure it is ECC!
Fixed! It was the charger port. All i did was clean it out with a metal pointed object. I also noticed the middle piece was touching the bottom edge. It could've been making false contact. So i bent it up just a little and voila problem solved.
Hopefully this thread may further serve as future reference. Thanks everyone for your help!

I know I don't have a Galaxy Nexus, but the Nexus S can also suffer from the same problem. I believe it's because of the USB ports that are the same.
Inside the USB port of the phone there is a flat plate which slides into the wall charger/USB cable, I've noticed that when this is "bent" down it will show that it's charging when it isn't, so all you need to do is to find something (I used the tip of the missus'one plastic nail file) to "bend" it up about a millimetre or two and all should be fine.
Worked for me, so I thought I would try to help out here because I know how infuriating it can be.
I had this problem a couple of weeks ago. I also had issues with being unable to connect my phone to a computer. I contacted Samsung, explained my issue and they sent me packaging to send it away. It took me 45 mins to get the computer to recognise my phone to return it to stock, but i managed it. I then wrote a nice little letter explaining the issue, that others also had the issue and that I recommended changing the whole charging board.
I got it back a week later and lo and behold, they'd taken my advice and fitted a new charging board. Now it might just be me, but the inside of the micro USB port looks slightly different. I just can't put my finger on why.
Hi, I had this problem but i sprayed "metal cleaner" on a toothbrush and wiped the contact and now it works fine again :3
This happened to me yesterday. First the phone doesnt charge, it was at 25%, After that i charged it with phone turned off, then turned on and battery whas 50% but still not charging. Turned off again, plugged the charger and it looks like was chargin, when i turned on again it was at 12%, like the charger just discharge it xD. After that the problem began, the battery icon shows like charging when unplugged....
Looks like i managed to clean it with a needle, now the chargin notification is gone, and i can transfer files via USB to my laptop, but still i cant charge with AC :-/
And when i plug the usb cable, the notification icon comes again :-/
OMG Thanks it's alive it's alive
After some time my charge port started giving me issues again. I tried messing around with it but all I did was break it. Eventually I bought a replacement flex cable and ended up installing it myself. Very easy to do. Looked up a video on YouTube and in 10 minutes my phone was charging again.

Just be very careful on step 6 "Some have reported the cable is soldered to the mainboard. This was not the case on this CDMA version. It may be soldered in newer revisions or the GSM model."
I broke my volume down because the guide didnt have a warning !
I hope this might help anyone else who is having problems

Damaged touchscreen - can the rest be salvaged?

Hi everyone.
After a sudden heavy rain, I got some water in my Gnex. I tried the old bag of rice trick, only to find out the USB port was not functioning any more, neither for PC connectivity, nor for charging.
Following the advice of a person I no longer consider my friend, I tried spraying some Isoprpyl Alcohol in the USB port. It did get it to work correctly, but it damaged the digitizer, meaning I get random touches on the lower part of the screen (where the Back, Home and Recent apps buttons are).
I took the phone to a service centre where they tried to clean it, but the issue remains. I'll go there today with my wife's phone to see if it's indeed a touchscreen issue or a motherboard issue. I'm not sure if I want to invest in a new screen (over $100 + maybe a new back cover since the current one has quite a few scratches and cracks) and I'm thinking of maybe upgrading to a Nexus 5 or Xperia Z (the latter being waterproof).
The question now would be, could I do something with the hardware? Like, root it, connect it to my wifi and use it as a web server, or connect it to my TV through an MHL adapter and get a "smart TV". Can I get it to ignore touches on the screen completely, and only accept an OTG/bluetooth mouse input?
Any idea is welcome

One day I got caught in a storm having my Gnex in my pocket. Vacuum and rice tricks didn't work completely, as the phone was working properly besides recognizing the sim card (Mboard issue). What I did was buy a broken screen nexus off of Ebay, and exchanged the screens.
Now I have a fully working mobile phone, plus an MHL connected - XBMC enabled smart TV box, connected with bluetooth mouse/keyboard.
Question: Why would you need to ignore touches on the screen?
As I said, after spraying the USB port with isopropyl alcohol, it appears to have touches all over the bottom part of the screen, as if someone was constantly keeping 3-4 finger and touching away at the soft buttons. Cleaning the phone in a service centre did not help.

Sorry, I missed that info. Try searching for 'touch blocker' in Google Play. Don't know if that would work on a Gnex though.
Another (hardcore) idea would be to disconnect the screen altogether.

Charging Struggles - Connection

Morning,
It appears that the charging connection on my M7 is a bit off. It just started recently about the last week or so where I have maneuver the cord/plug around to get it to charge and even then any slight adjustment will stop the connection. It's resulted in multiple instances where I left my phone to charge and came back to it dead.
Does anyone have any experience with this? I thought it was the cables themselves but after trying several and knowing they work with other phones it appears to be the internal connection on my M7.
I haven't dropped it, gotten it wet, or any of the sort.
Any tips/advice/help are greatly appreciated.
Thanks!
Sometimes the contacts in the phone port get dirty. Take a small needle and lightly scrape off the five little contacts in the port. Has not happened to this phone yet, but with my old incredible it did once or twice. If that dosent work, the port may be faulty.

Ended up bending the whole connector back into place. Seems it go bent towards the top. Connection appears to be more stable, we'll see how it holds up.

[Q] Galaxy S3 - Replaced external speaker after water damage, still no sound

My S3 took one of those unfortunate, unexpected dips in a porcelain pool. It was buzzing and crackling before I could get the battery out. Let it dry out and everything was working except for the external speaker. No ringtones, speakerphone, music, etc. So I ordered a replacement for the external speaker module, dissected my phone and cleaned the couple spots that showed traces of water, and put it back together... and the speaker still doesn't work. So assuming there is nothing wrong with the replacement, there is probably nothing wrong with the original... and now I have no clue what to do.
I'm not generally real adventurous with my phone. It's not modded; still running the original OS that came on it from Sprint, but it's not under any kind of warranty or service agreement (and the indicator is now purple anyway.)
The internal speaker works and it vibrates. Microphone and camera are okay. Any suggestions? Please?? "I didn't answer my phone because I didn't hear it ring" is already getting to cause me problems.
There's a good chance that when your device took a swim something else may have been damaged. Did you make sure to check that all the connections were carefully placed, before connecting the new speaker ? Also you said that there were signs of water still in the device when you opened it. How did you dry the device ? Did you use Rice ? Or descant ? Most times just air drying the device does not do the job.

I did just air dry it. When I opened it up there was no actual water remaining, but there was a white residue around what I am guessing is the internal speaker. I used rubbing alcohol on that to remove it. All the ribbon cables are securely in place and while I'm not adept at circuit boards I don't see anything on the motherboard that would appear to be loose or damaged. I can put it in rice if you think it would make any difference at this point.
Yes. I would still suggest putting it in rice for a few days. Even at this point. Electronics and water don't mix well. Especially smartphones. I've seen devices still have some moisture trapped in them, even after three days of Air Drying. Although the rice may not solve the issue. It's worth a try. If that doesn't resolve anything. ODIN the Stock Tar. If that still doesn't resolve the issue, well then it's time to take it in, and have a repair center look at it.
