I woke up yesterday to find the micro USB end of my charger cable had melted while plugged into my phone.
I have used this cable for months, it was plugged into my macbook pro overnight. Not sure what happened, but there was a popup on my mac that said "USB port disabled...device drawing too much power..." (paraphrase)
Anyway, my phone, cosmetically, is fine (save for the burnt plastic smell), BUT the headphone jack doesn't work, and I can only use speakerphone to make calls or the caller doesn't hear me. (also tested the mic w/ voice recorder app and it doesn't work) And now no matter what cable/brick combination i use, i always get the "slow charge" message.
So I am pretty sure it fried at least the mic. the headphone jack, and messed up the charging port.
Any idea if this is worth fixing? Or even possible to fix?
The charging daughter board is around 15 bucks on eBay. It's fairly easy to install.
I wore out my charger port so I replaced it and everything works now except the mic. I've since research and it seems there are two mics once is the speaker phone mic on the charging board and another on the secondary board but can't confirm this. I'd recommend buying from Amazon as that may be a more reputable dealer. I'm forced to use a headset now to talk
Thanks for the info.
I reflashed the stock kernel and this somehow fixed everything but the Mic.
Now that the headphone jack works, I can use the headset to talk.
Still having issues with the charger port... Always get the "slow charge" message, and the phone will intermittently stop charging unless I unplugged and plug back in.
Might buy the replacement port as per your suggestion. But, I had an upgrade and was able to get the LG G3 for free so I will tinker with the M8 and see if I can't fix it for fun.

So when the unresponsive screen when grounded issue came about, I didn't really notice the problem much myself. However, recently, and I'm not sure when this started, the screen has become horribly unresponsive when charging any time! Doesn't matter if it's on desk, in my hand, stock charger, 3rd party charger, etc., if it's charging at all, the touch screen only accepts half or less of my inputs, making typing impossible. Is this due to the last software update? Anyone else experience this issue? I would exchange the phone, but not if it's not going to help anything.
this happens to me when i use my cheap ebay charger
The fps lifting kernels fix this.
+1 for symtoms seen when using a wonky charger/cable.
+1 due to cheap charger - anyone know why this happens? is the OEM usb cable different spec from the cheap ones?
Hate to beat a dead horse, but the same happens when I plug my phone into the charger I got from eBay. Kind of disappointing, considering that I would otherwise be able to charge two batteries at the same time.
I notice this issue with the stock charger.
I believe the issue was when its not grounded..
Being plugged in is just about the most grounded your phone can get.
That's not the problem.
Starting to do it to me also now.
Just to be clear, this happens to me with the STOCK charger.

I'm having the same issue. i just chocked it up to the new kernel.
one thing i did notice is it seems to be intermittent. Yesterday night, it worked fine. this morning(conveniently when my alarm went off) i could NOT get the dismiss thingy to slide down.
Anyone else experiencing this? I do think it got worse after last software update. Would be nice if the next one improved things.
I emailed support, they did not say anything about it being a known issue, and suggested a factory reset. If that doesn't help, they recommended using my warranty. Would like to hear from more people before going through with the reset.
It happens to me when charging via outlet. Charging via USB connected to computer does not produce the issue.
I think it has to do with grounding.
Same thing happens to me! I noticed it with my aftermarket wall charger.
Bringing this back up, happens to me with a Stock charger.
Is it really the kernel? :\
@Person who said charging is the most grounded, the stock charger is not grounded ( in AU anyway ) and therefore it is the LEAST grounded.
ive noticed this happening over the past month or so. i've got to admit i've only really noticed this when its plugged into a usb cord i got off ebay. relieving to think it might only be an issue with it being a cheap cable and not the phone but i'll verify tonight with the stock cable.
I've been plagued by this problem for weeks and just discovered that it only happens when charging. I use the stock charging cable and wall adapter. I'm very, very happy to know what the problem is. I'm going to start testing this at various locations.
EDIT: I've tried this on both the wall adapter at work and on my work computer's usb. Same problem, though it seems worse when plugged into the wall outlet.
The touchscreen is fine on my sprint brand car charger and on the usb charger on my laptop. However, it starts missing taps when I plug my usb cable into my usb car charger. I'm going to best buy tonight to buy a different charger and see if that helps.
Sent from my Virus Infected Evo using the XDA app.
I have these issues as well with the stock charger and cable regardless of which kernel I use.
I just want to let you know that my micro-usb port has stopped working correctly after 1 week of use It's still making contact, but i have to press it upwards, which left me charging my phone overnight by putting a remote control under my cable to keep it lifted.
ATM is a minor issue, it doesn't really bother me to charge it this way (i love my GN ), but i was thinking that i might need it to work properly in the future (a dock or speaker) so i've sent it for repairs. Waiting to get it back
I've been searching for similar issues and i've found that the micro-usb port is known for being easily damaged, so take care with yours.
Cheers!
I've had my G3 for approximately 8 months, and I've been using it normally, wihout any kind of abuse, and using the cord that came with it to charge the battery. Yet, a very annoying problem has surfaced : the plug releases itself very easily as of late. Just slightly moving the phone when charging disconnects the plug. I checked the connectors on the phone and on the cable, and I could not find any kind of debris that would prevent a good connection. Has anybody else had this very annoying problem ?
i have a similar problem, not the cable unplug itself but the cable sometimes have to be on diferent position to plug suceful in the phone!
one thing you can do without have trouble is to buy a wireless charger (if your phone supports it in NFC antenna) and charge the phone with that! OR if you are in guarantee time you can send it to there and see what the technians says to you.
I've had my G4 since almost launch day and within weeks the supplied USB cable stopped charging the phone. I thought it was a cable problem, but it worked fine with other devices.
I tried other cables with the G4 and these still charged it so I thought nothing more of it until charging degraded with every USB cable I own to where the phone would only charge 20-30% during an overnight charge and the phone would frequently not recognise it was plugged in at all. I contacted LG who did a repair under warranty and all was fine.
I've now had the repaired phone back for about 3 weeks and the same problems are starting up again and it's only a matter of time until I am forced to return again for a repair.
Is anyone else having similar problems? I thought I may have just had an unlucky manufacturing problem, and the LG reps confirmed that to repair my phone they basically replace all the internal circuit boards and components rather than just replacing the individual component that is faulty (in this case the USB/charging port)
Basic debugging includes asking stupid questions, so please forgive but still answer any of those
Are you using a different charger? If so, check if that one is within specifications and if you do send in for repair again, use a different charger.
Are you propping up the device at an odd/weird angle or in a dock of some sort with the cable attached?
(As they replaced the entire print, it's probably not this, just the USB-micro port bent or broken.)
You could double check the wall outlets being used, there might be some kind of electrical problem there.
Either using all kinds of fancy electical testing gadgets, or stick a USB light into the hub or charger, does it flicker?
When sending it back for repairs, did they check the stock charger as well?
Hopefully these questions help you find any logical or plausible cause.

Hi FreezyExp,
1. I am using the standard charger that came with the phone, but this has not been repaired/replaced. I have tried other chargers too, but all the same issue.
2. No weird propping up or anything like that. If I hold my phone while it is plugged in it is constantly vibrating as the charger connects and disconnects, and if I place it on the desk to charge I have to ensure that I have at least 3-4" of cabe "on the desk" to give it enough support to make the connection.
3. Wall connection is fine and I have tried it with a range of outlets around the home, both with extension sockets used and plugged directly into the wall and there is no different. No flickering light when using a USB light either.
4. When I sent it back all they asked me to return was the main section of the handset - so no battery or rear cover, no cables or chargers etc
It does seem to be the same issue as last time, a USB connection becoming loose from the main motherboard, but it seems weird that I have had the same issue twice in the space of 4-5 months.
I've been having some sort of problem with my G4 usb port. If I plug it in to a computer, it will lose connection and get a connection again if I barely touch the end of the cord at the phone end. I've tried many different cords and different usb ports on my computer, but it still has problems.
I can't fast charge, either. When I plug it in to fast charge, it actually starts discharging even faster. I've had some extreme battery life problems, too. It drained from 100-36 the other night with everything disabled, and it's been doing that kind of thing a lot lately. I'm guessing that the charging port is what's messing up my battery life because it won't charge correctly.
Never dropped it or anything.
I got my G4 on January 24 and my USB port has also failed. I am getting a replacement from Verizon, but am concerned that a six month old phone has this issue.
I also own a G4 H815. A while ago the phone started not receiving any charge from the cable and I would have to prop it up from right under the cable's micro usb end. Thought it was because it was bent inside the port and not making connection with the cable so I had the port replaced. Now I'm experiencing the same problem and I think it might be the cable that's already gone kaput and is effing up the port itself. I took the phone to the same place to get the port replaced again and bought new cables (I lost both the original adapter and the cable, which were charging slow anyway. Now using a 2A Asus adapter which works great) and when I asked the guy at the repair shop, he says it's a chronic issue with G4 devices. I don't really understand how it would happen twice in just a few months even with a new charger port. What should I make of this? Did they replace my port with an already faulty one, cahrged me full price and now trying to sell this bogus or am I really doomed with this phone?
My phone does that when using a USB hub with HDMI, it does work with my friends S20+
What can it be?

Dex needs a Knox-App called "KnoxDesktopLauncher" in /system/priv-app/. Make sure its on your device. Maybe you have deleted it.
Not sure if related, but today I noticed similar issue on my regular S20 with USB-C earphones, they kept connecting and disconnected, which resulted in media pausing, and audio playing through loudspeakers. Wiggling USB plug gently, and phone recognized earphones, only to lose connection shortly against.
Gently Wiggling USB connector in all directions, including pushing it deeper, and pulling it towards yourself, reproduced the problem everytime, which leads me to believe the USB-C port is broken.
This is strange. My phone is just around 4 moths old, I very rarely use USB-C earphones, and last time I checked (around a month ago), everything worked fine. The only thing I plug on a daily is a charger, never in a car, or in any place where port might be stressed.
The reason why I noticed this issue only today, is because I wanted to listen to some music, and had AKG USB-C earphones laying close to me.
USB-C charging cable managed to break the port, in such a short time, just wow.
By the way, charging works fine, USB is acting up only when data transfer is involved.
So check with other USB-C devices, maybe your port is also broken. Plug bundled AKGs, play some music, and wiggle plug gently, music will pause if connection lost. Also you'll see headphone symbol flashing in and out.
I think people might not notice this issue, because pretty much everyone I know switched to wireless, so this can remain unnoticed for months, or longer.
And what's the case with root? I've rooted mine with magisk and since then Dex only connects/disconnects... Is there any option to get it working on a rooted device?
Same problem here, not Dex (i don't use it) but with charging.
It keeps connecting/disconnecting while charging if I move the cable. Really annoying.
It sometimes also charges slowly or not at all while it does say it is connected...

I think our phones have broken USB-C ports, and also, after reading many reports, starting to believe that S20 series phones have a weak port design. I'm very gentle with my tech, so at least in my case, it's either manufacturing problem, or a bad port design.
From what I gathered online, first symptoms of a failing port are problems with anything data related, like in my case, USB-C earphones connecting/disconnecting causing media to pause, then problem becomes more severe, when it's not just media pausing, but phone losing data connection entirely, resulting in complete connection loss to a peripheral, when you have to wiggle plug to reconnect, only to lose connection again shortly after, and finally, these data issues lead to charging issues, like ones you describing, connection loss to a charger, appearance of charging.
I still have around 20 months of warranty left, but sadly right now need my phone badly and have so much data that I need to back up, so warranty is not an option, at least for now, I have to buy wireless charger, in case USB-C port fails entirely. S20 keeps disappointing me.. Sigh.
