USB menu notification keeps popping up when unplugged - LG V20 Questions & Answers

Anyone have the v20 USB port malfunction like this. It's not software as I factory reset 3 times. When my phone is unplugged it keeps popping up the notification to use the phone as power source. Sometimes it will vibrate over and over turning the notification on and off like it's being plugged in and unplugged over and over. T-MOBILE is sending a replacement, but I just wondered if anyone else experienced this. It is ashame because I bought this phone at launch, and it's been flawless otherwise. It just started doing this, this week.

Mine started doing this about one month ago. After resetting a few times, it still did it. I pulled the battery for a few minutes and cleaned the terminals on the battery and the phone, I also used an alcohol dipped napkin and cleaned the USB port as best as I could. Oddly enough, something fixed it. I couldn't tell you which.

I called and they sent me a warranty replacement. Oddly enough, it took about 4 days to get it. My phone though stopped doing it 2 days before the other phone arrived. I replaced it anyway, but am curious as to whether it will would've done it again. It was very annoying when it was happening

[Q] Nexus 7 seems to have completly died

I have searched everywhere on xda and all over the web but I just can't find a solution. This is my brothers tablet and he just can't fix it. He bought it new from Comet and used it for a few months and then rooted it. Then a few months later it wouldn't upgrade the android version. It downloaded it OTA and when it tried to install it said error. I ended up flashing the latest version which ended up unlocking the bootloader. All was fine for a while until the stock usb cable had broken, charging worked very slowly when it was in a certain position. So I tried using some other usb cables and it said it was charging but it was ridiculously slow. After several hours it only went up a few %. Then the problem got worse, the tablet said it was charging but it never seemed to go up in battery. I bought a new usb hoping it would work and nothing seemed to have changed. He kept playing on it untill the battery was so low it powered off. Then we tried charging it without powering on and it looked like it was working (black screen with a charging icon). When we tried powering on the battery icon was empty and it went back to square one in a sort of loop. I had looked everywhere and some said we had to hold power down for 30 seconds but it just did this loop over again. Holding power and volume down did nothing, so we were at this one point and it was charging for ages and I gave it another go. Still nothing and after a few attempts it just went completely black and nothing appears on the screen at all. I opened the back without tampering anything at all to see if the battery had come loose and evrything looks ok. I know the warranty has been voided by rooting, unlocking bootloader and opening the back so returning it wont help, and comet shut down a while ago so they cant help. It was quite expensive for us so I don't want to give up just yet. I hope the xda community can help
Sounds like a bad USB port.

So you don't think the battery has any problems? If not how can I solve this problem? Can i replace the USB port or can i buy any docks?

***Anyone help? Strange problems..***

Basically i was out at a nightclub 2 saturdays ago, my drink was spilt down my leg with my phone in the pocket. From the sunday after that my phone has been nothing but a pain in the arse. It charged on/off , while the phone was plugged in it would go down percentage. As well as this, it got the grey battery loop. Recently when i plugged it in, it would just vibrate every 2 or 3 seconds, nothing showing on the screen. So far i have solved the battery problem, i scraped the dust/lint out of the usb port and bent the charging port back into the middle a wee bit.
As well as this, certain apps have stopped working. Facebook wont save photos, snapchat won't load stories, save photos or let me send snaps. Instagram crashes every 2 seconds. All of these work 100% on other devices leading me to beleive its my phone. I have already factory reset it and this did nothing. Does anyone have any ideas? My head's melted. Phone is rooted but standard

Critical issue with Android 6.0 on DT2

Now that my DT2 updated to 6.0, it has developed a showstopping problem. It instantly powers off at random times, usually when I'm using it. Worse, the power button is ineffective at restarting the phone. The only way to restart it is to plug it into a power source and then press the Power button after it acknowledges that it's charging.
It used to do it only one or twice per day, but now it's doing it constantly.
I've already performed a factory reset and then a cache wipe, with no change.
Verizon confirms that it's happened to others, so it's not just me.
Is it possible to revert my DT2 back to Android 5.1.1?
Has anyone else here experienced this, or have any suggestions, before I tell Verizon to send me a new phone?
Thanks in advance.
Sounds like a hardware issue to me, especially if it did it prior to the update as well.

I should have mentioned, it never happened in 5.1.1.
yep, i'm having this issue as well since i updated to 6.0 three weeks ago. started about 3 days after the update, i plugged my phone in over night and i woke up to it dead. couldn't get it to charge worth anything. would only go to 4% and stop. using original charger. won't go into turbo charge. stopped by the store and picked another charger and a portable battery and used the pre-charge on the battery and it finally started charging again, but not at the turbo rate it should have. it drained the pre-charge and got to about 45%. plugged in in once i got home and it still didn't see turbo charge, took about 6 hours to finish charging. over the next few days it was still slow to charge and would randomly lock up and then reboot itself. a few days later i woke up to the phone almost dead again, even though it was plugged and showed charging all night.
did some research, found more people with the same issue. Lenovo/Moto and Verizon support all suggested put it in safe mode, then see if it still does then same thing when all the third party apps are disabled. did this and yes, it still charged slowly, and while plugged in it the battery was still discharging (percentage number was dropping... pretty quickly). the next idea was a factory reset. haven't done that one yet myself.
here is a page to one of the lenovo threads about. seems to be the main on there at this point .
https://forums.lenovo.com/t5/DROID-TURBO-2-by-Motorola/Turbo-2-won-t-charge/td-p/3261260
I just posted this thread in the general forum for the DT2. Wasn't sure if you'd tried this yet or not - but solved many issues for me.

I also had issues with my DT2 charging. After upgrading to MM, the quick charge was sporadic, and it wouldn't work. Then I had issues with the charging port in general. If i barley wiggled the cable it would not charge, or send files via a computer.
I went up to a local Verizon store, explained my issue, and i had a replacement phone in about 3 days. They ran a special test to test all of the hardware on my phone, and sure enough when it got to the last test, which was the usb port, it failed.
I received the replacement phone with MM already installed, and have not had any issues with the usb port...so far. LOL
I ended up sending my phone back to Motorola; just got it back and it's till got 6.0 on it. It repeated this showstopper behavior twice today. NOT HAPPY.

Nexus 6P bricked while charging

Unlike my Sammy Tab S, which I use xda to help root and run custom roms and the like.. I have been pure Nexus 6P with Google fi from the start.
So when I had a battery drain issue.. both in cold weather and in heat.. but many months apart, and saw others worried about it, I got a replacement from Google. I do pay the $5 insurance each month in my Google fi plan.
But now this was different. I had recently sent and received texts with my phone by my side on a charging stand. And I hear a sound like a notification sound.. not sure what it was exactly, but I pick up my phone to check it and it is black. I try to swipe.. nothing. I touch the power button.. nothing.
Now I am worried.
I take the case off. Jam my thumb down on that power button until I think I might bleed.. nothing.
I quickly look up the power-reset sequence.. power+voldown... hold it nothing. Try every conceivable combination.. holding for 20 seconds.. nothing.
Normally I might come here looking for help. But I am afraid this is beyond help. Google is sending a replacement.. after I did the try this - try that dance with them. Finding my original USB-C cable for example.
Man.. I don't know if this is a common problem.. or will become one because of some recent update. But I am set to re-setup my phone.. AGAIN... with a new replacement. And I am wondering what my options are going forward.. Google fi means some kind of compatible device.. so.. what.. get a Pixel? Leave fi and get a new Samsung somethingorother? I hate their interface.. love the camera.
So.. this thread is juts a "me too" for some future 6P owner this happens to.
[UPDATE] the thing came back to life!
I swear I tried different USB cables and different ports.. a PC, 2 different USB chargers.. and I got nothing.
Just now, an hour or more later, I tried the cable and charger it was using when it "bricked" and I saw a small red light in the top left corner for a second.. and the dang phone began charging. It showed 3% battery.
So, maybe, what happened was I did not have the cable plugged in correctly.. or maybe it had another mysterious fast drain. The power graph for those is quite ugly.. from 60% or more to nothing! That's why I sent the first one back.
In any case, I am going to now see if this will charge up and be "normal" for me again. I have cancelled the replacement phone order. .. who wants to reinstall all their apps and such if they can avoid it?
I am still very curious as to how nothing I did had any affect... but now it just works. There's something funny going on here. Its not like I was taxing my phone and it got hot or anything.. it was cool to the touch when I got it out of the case. Something is not right about these phones.

Hey... If your device shut down with 60% left you might be victim of the same problem Q's other users I this thread: https://forum.xda-developers.com/nexus-6p/general/nexus-6p-randomly-shutting-50-youre-t3522911
Unfortunately, it's a common issue with no real solution except a warranty or battery replacement...
Good luck...
I had the same problem, it solved itself in a couple of hours, I was to send it to assistance but it booted up randomly trying after 2-3 hours of rest

Charging Issue

I just got my device and of course I was intrigued by its water resistance so I tested it out. After a couple of hours, I went to charge it and I got a moisture warning: saying that for my safety, since there was moisture in the Type-C port, the device would not charge. I dried it out as best as I could and then rebooted my device and now when I go to plug it in, it spazzes out and charges and stops repeatedly and makes the charging noise constantly. I haven't tried to let it dry overnight yet, but I'm just putting this thread out there to see if anyone has any tips, besides not dunking my phone underwater, or if anyone else has experienced this too.
The S7 has this feature. Let it sit in rice or silica. Turn it off for the night.

It doesn't give me the moisture warning anymore though, it just charges and stops charging rapidly.
RMA it. IP68 means 1.5 meters of water for 30 minutes...if it wonks out with less than that, its defective.
I had my S7 Edge underwater for over an hour at the pool last summer, trying to see if I could drown it, and it held up like a champ.

After a day, it's working now. Thank goodness for its amazing battery life. But, I found another charging issue, check out my new thread.
Same issue with me. And I didn't find any solution for that yet.
Hope now your mobile will be ok, if not then first you need to put it on service center they will suggest you better idea.
My phone hasn't been anywhere near water and I haven't been able to charge my phone (unless I turn it off) due to the moisture warning. Before this warning started to appear my phone started rapidly making the noise the phone makes when plugging in in and flashing the usb notification even though I wasn't plugging it in. It was super annoying because it did it every second for a long time. That has since stopped but everytime I try to plug it in I get the moisture in charging port notification.
Same situation here. I tried to put G6 in a rice over night, without help.
Also I put my device on a coffee machine several hours to get rid of "phantom moisture", without any results at all. I think it's now software related problem.
By the way i can't charge my battery over 50%, to charge it until 50% I need to restart device with attached USB. By the way notification with vibration effect every second is freaking me out.
If someone find any solution please share...

Exact same thing happened to me. Some night the bogus moisture warning would interrupt the charging that had started.
By luck and coincedence, I had a wireless charger at work,. and have just received 2 more for home from a woot deal.
If it wasnt for them I'd be screwed.
I took a chance on LG this time. Never again.
Took this without a case on in the pool, clearly lol no issues at all. Yes at 1st it did tell me moisture present. But I didn't need to charge. Later before charging I did take a air can and blow out the port just to be safe and all was fine.
My G6 was submerged for about 5 seconds, and this about a month ago, but now every time I go to charge it, it says that charging is blocked due to moisture detection. I have a feeling that it being hot and humid out and it being in my pocket doesn't help. I need to reboot the phone, and it will usually start charging after several attempts. Haven't tried leaving it in rice yet, but will give it a shot.
Had the same issue as the OP. The only sure fire way I have been able to get my phone to not pop the moisture message and charge is to plug in the phone, and reboot leaving the phone plugged in. It works every time so far.
Software issue?
I have started to suffer the same exact issue LG G6 and I've also not brought the phone anywhere near water or moisture. I also found the charging workaround, charging they phone while it is off. So I leaning towards agreeing it's a software issue, could it be from installing something like Avast? that's the only application I've installed recently that I can recall.
Possibly Solved
Have had the same issue since this last update that was pushed out. Let me ask everyone. Did the "Hi Security" app come on your G6 as well??? I cleared the cache on the app and have not had the issue come back so far. Like everyone else here, I've tried EVERYTHING!!! But this seems to be holding.
possible solution
Hi all,
I think I have found a solution that is working for me. Maybe others can give it a go and see if this is a work around?
For me, as a developer I had DEVELOPER MODE set to on and when plugging in a USB cable to the computer, I had set the default option to always go to "File Transfer". I changed this back to just "Charging" as always and now my phone doesn't seem to have that annoying moisture warning when I go to charge my phone.
Can anyone else give it a go?
thanks!

Still seeing this issue and I don't have Avast on my phone. My guess is that it the software for the sensor is overly aggressive or not clearing the flag when you do get some moisture in there.
I have been probing testing this issue and found if I also plug the phone in very slowly sometimes it works fine. Only about 50% of the time though. Its weird. The plug it in and reboot method works pretty much every time.

Giving this a try will let you know how it works for me!
It's definitely a software issue
I posted that after clearing the cache on "HiSecurity." The error seemed to stop popping up. So I dug in deeper. I can't find where to get to developer mode. I hope someone can share that process??
However in the meantime, I went to Apps, View System Apps(The upper right corner 3 dots), Special Access, Modify System Settings, Go down to LG System Server, tap, and select "no" for the write system settings.
Also under "show system" you can scroll down to "LG System Server", tap. tap "notifications", and finally tap "silent"
This will at least get rid of the annoying vibration every few seconds along with the sound. It does not however completely get rid of the "moisture in charge port" message when plugging in charger.
We need to find out what it was from the last system update, caused this issue, that is exactly when it started on mine and many other people. It's not hardware, software is what we need to be trying to filter out.
