USB Notification even when phone not connected as mass storage - Sprint LG G5 Questions & Answers

I just picked up my new LG5 and for some unknown reason the phone keeps on displaying a notification telling me that the device is connected as mass storage, well the phone is sitting at idle and nothing is connected to it. This notification keeps on popping up to the point that I had to shut off the phone, due to this because this will not go away. Has anyone experienced something similar to this? The local sprint store is closed so I may just have to take it back tomorrow. The phone is running on Stock out of the box LG Sprint OS.
Thanks,

Figured out what the issue was, after I posted this. Issue was attributed to water getting into the circuitry when the screen protector was installed by the Sprint folks at the store, took out the battery and and let it dry overnight. Phone seems to be working fine right now, taking the phone back to the store for replacement.

[Q] No power, no charging LED, no Fastboot

Howdy, guys.
I've got my One rooted, unlocked, and was running a CM10.2 nightly build. Everything was working fine until yesterday, when my battery started to rapidly discharge. I woke up with 100% battery, and after about 15 minutes of playing music it was down to 30%. I recharged it and started noticing rapid battery loss, about 10% per 15 minutes when the phone was idle.
Worried that this had to do with my ROM, I flashed the Eclipse Google Play Edition v1.2 ROM. However, the drain issue continued. I decided to let the phone fully discharge, then try powering it up again.
When it was fully discharged, I tried plugging in the phone. No LED came on and I couldn't turn the phone on. I've let it sit for over 2 hours now with the same result.
Some posts with similar symptoms have mentioned plugging the phone into a Windows PC and experiencing the "USB device plugged in" sound alert. I am not having any such luck, and what I currently have is a very aesthetically pleasing paperweight with no function whatsoever.
Has anyone else experienced a similar issue, or found a fix?
none
I would take that back to Verizon were i you, sounds like a bad battery to me, chances are remote that it's the phone/hardware/software. they have to repair it despite the fact it's rooted, they probably wont even notice lol
Were it me, back to verizon we go
Last Sunday, listening to music with HTC One (bought on Sep 11) on the charger, it suddenly went dark. Would not reboot, no charge light either. Went to a VZW store, they're shipping me a warranty replacement.
I wonder whether my habit of leaving it charger-connected whenever it's sitting on my desk (i.e., way beyond the fully-charged point) somehow stressed the battery (or the charging circuitry) -- though that habit never impacted my two previous HTC models.
When you hold Vol+Down and Power do your home and back arrows blink? If so, point the phone sensors (the two on the front on the left hand side) into a bright light. Then hold down Vol+Down and Power. It should boot. I'm not sure why. But it worked for me today after installing a custom recovery. -shrugs-

I've got a replacement being shipped to me, and I'll send them the old one when it comes in. Currently using an old Samsung Stratosphere as a replacement, I was just hoping there'd be an easier fix or something simple. Thanks, though!

Major Battery Issues

Hello everyone,
I have a major issue regarding battery.
Here is a rundown of what has happened.
1. There was moisture detected at first by the sensor and there was in fact moisture there after I plugged in my usb charger in and saw water around the usb-c connector. This was due to humidity most likely as I live in NJ.
2. I cleaned it out with a cue tip at first and nothing changed. Plugged my usb charger back in to see if water was around it which it was not obviously.
3. Left my phone on overnight and then the Icon went away but, I could not charge my phone anymore despite their being no notification showing me that the phone was incapable of being charged because of "x" reason. I also made sure to use a shop vacuum to remove any other residue inside the phone.
4. Turned my phone off and then I was finally able to charge it.
5. Turned it back on and then the issue I have now is happening along with the fact, when I use my charger that came with the phone, I get a notification that I should use the charger that came with phone if I want it to charge faster....
Not only that but, to get it to charge occassionally I had to turn airplane mode on and THEN it would charge. This is spotty because it works sometimes, sometimes it doesn't.
Today I hit a breakthrough. After doing a factory reset (that literally did not change anything at all. Same problem, despite everyone at reddit suggesting a factory reset) I loaded my back up file that I created before the factory reset and *poof* the issues described above vanished.
However. When I put my phone into airplane mode and turned it off (tried to mimic the most successful variables that allowed me to use the phone without issue) and then plugged a my usb cable in, it charged no problem. Then when I turned the phone back on, the evil bleeping and screen dimmer of death came back on.
I am not up for a loaner phone and I can not wait 2 weeks for a new phone seeing as I work and people are always calling me.
Recommendations?
What do I do if no one responds?
Bump?
Not sure what else you can do. Sounds like the port got shorted out partially. I suggest grabbing a Qi charger and going that route in the interim, that should work without issue, unless the circuit on the board is the issue and not the USB port. I assume you are using a different chable/charger than the one that was wet?

Try leaving your phone all night in Rice. The rice absorbs moisture from the phones when they fall into the water.

G7 will only charge when powered off

I seem to be having the same issue as found on this thread, can't find anything here though.

Anyone else have the same issue and found a fix? Guessing this might have to go back to lg.
Thanks!

I started getting this issue yesterday a day after I got a software monthly update for Nov. I normally shut the phone off to charge but sometimes leave it on. When plugged into something it doesnt seem to detect its plugged in. I even swapped cables to a slower charger and same thing. It doesnt see it.
When I fully charged it off, It beeps the battery and does a circle hue randomly by the home button but than detected the connection to pc. I ignored it and started up again but without the beeping, just wont charge when on. There is no dirt or anything in the unit,. I have not moved any-wires, they have been sitting in the same spot on the counter since day 1. I'm gonna try a factor reset if it keeps happening a day or 2 from now.
Same problem here, it was behaving strangely few days ago (charging problem right away but worked in the end so let it go) and now it charges only when off or if plugged within 30 seconds after turning on and only on normal charge speed (not quick charge). Tried to wipe apps and everything, did the facrory reset 2 times but still nothing.
I have similar issues with charging my g7, first give me notification of moisture detected on USB port, then can't charge normally need to plug a few times and sometimes get slow charging, i was thinking have faulty USB port, and have poor battery life.
Then I turn off and put the cable and charges normally and realized that it's software issue.
I flash the ULM10i firmware and now everything work flawless the USB port charges when it's turn on and have very good battery life now.
As an update, I called LG and they basically stated that it sounds like a software issue and to send the phone in. I declined hoping to get another update that would fix it.
I have yet to get one from T-mobile. Long story short, it corrected itself and now charges off or on and no longer does the beeping. Whatever it was, was a bug that temporary for me.
same problem here; no moisture errors, aleatory starts charging when it's on, poor battery life; mainly starts charging with the phone off
problem solved! I've forced LG BRIDGE to reflash the ROM and voilĂ , all working like a charm. Just download from lge.com, install LG BRIDGE, under "software update" ... "update error recovery" and it will download and reflash the working ROM.

Wonky behavior after update (Verizon)

I've had my phone for a few months now and I've seen 2 updates on it. Generally speaking the device works fine but I was woken out of my sleep due to the phone bootlooping. I shut it down and restarted it and it worked fine. I thought oh great, not this again but still chalked it up to just pure randomness. Then yesterday I started getting this notification that the charging port may have debris or moisture and that it wouldn't charge properly despite me doing nothing different, never getting it wet. So I followed the directions and blow dried it gently and checked for debris. The message stopped but then started up again today. I decided not to chance it and took it to Verizon. They were really too lazy to actually look at it instead just ordered a replacement device which I guess I'm ok with but that doesn't explain what may have happened.
Anyone else having wonky issues with their phones after the last software update? I have not tried a hard reset or anything thing else yet but it is no longer fast-charging. So far that seems to be the only issue. Any insights?
*Edit: Did a factory reset and I thought it would resolve but it didn't. What it does now is that randomly whenever I plug it in either to my PC or Charger it will randomly shut off and go to this screen. The above error about the charging port continues to happen. Even though it says fast charging it is not.

Note 10+ won't charge - temp to low?

This just started today and the temp is not low. Is there a way to fix this error or do I have to replace this piece of junk?
I already tried restarting several times. Whew the phone is off, it goes back and forth between charging showing an error on the blank screen.
What type of error? Did you completely depleted the battery? Any moisture inside the port due to inmersion or high humidity in the air? You can try wireless charge also, just to check if the port is the culprit

i had similar issue, on my old Samsung Tablet, Note 8.0
It used to show a system popup that temp is to low
when i tried to charge it and charging was "paused"
I struggled with this issue for quite some time.
Eventually, i took tablet to Samsung Care.
It was the USB port.
They replaced the USB port and issue was sorted.
Then i had the opposite with my Samsung Galaxy Gear watch.
When i wanted to charge it, i got a pop up
temp to high.
Problem again just started to get worse.
Again took watch, to Samsung Care.
Replaced the watch battery, fixed.
Learning from my experience, is that it could be a hardware issue.?
Further, matter will eventually just get worse.?
My Samsung Galaxy Tab 8.0 i struggled for a few
months, when it eventually just gave in.
Good luck.
I saw some youtube videos about the 'temp too low' issue, the temp sensor is part of the wireless charging module inside the phone. could be a hardware issue
I called Samsung tech support and they did a remote connect session. The lady determined it was a physical issue and is having me take it to a service center. Lucky the place is right down the street. Unfortunately, it won't be until after Thanksgiving.
I did get it to charge somehow and I think it could be a charge port issue. As much as I tried to manipulate how the charging cable sat in the port, I couldn't find a position that would allow it to charge. It just decided that eventually it would take a charge.
The tech support lady said it'll be taken care of free of charge. That's really all I care about. If it were a T-mobile insurance claim issue, they'd probably tell me there was water damage and find a way to charge me, like all phone companies do
