Hello all. Few days ago i've got refurbished LG v20 (F800S). Since that i expiriencing very strange problem. Almost every time when i connetct phone to my pc, its starts to charge and after few seconds the message pop up (slow charging due to not original cable) and there is no options on notification bar (charging, MTP, etc.), also it doesn appear on device manager which means its not driver. Choosing MTP as default on developers options gives no effect, aswel as enable/disable debugging or oem unlock. But sometimes it connects just like it should to (without changing usb port, or cable, or rebuting pc or phone). I tested it on 4 usb 3.0 ports and 2x usb 2.0 ports of my pc, and 2x usb 2.0 ports of my notebook. Everything worked fine at least one time with both 3.0 and 2.0 ports. I've got 4 differenct type-c cables, and it acts the same with each one of these cables (or usb ports). So i'm asking is there problem with charging port of my phone?

Hello guys, recently my micro usb port is not working properly, the pc's can't detect it(tried 4, mac,windows and linux os's) so is not the computer, changed 3 cables, so is not the cable, something must be wrong with the micro usb port, it can charge(usb, wall power) with no problem, but the phone is not detect by pcs, adb, etc, any idea what could be the problem? how can it be charging and the usb debbuging protocol or whatever isn't working, can I screw the transfer usb protocol? but the charge protocol in the same micro usb port could be still working, thanks in advice!

I had the same problem as you, it was impossible to make any computer to recognize the phone. Moreover it charged very slow, the phone thought that it was always plugged to the computer even if it was connected to the wall charger.
I did a factory reset, but the problem persisted. I called Google and they sent my a new phone, which now works perfect.
Hey guys, quick question for those of you with the s5, and the usb 3.0 cable.
I am trying to transfer files from my windows 7 pc. with the usb 3.0 cable.
USB 2.0 works just fine, I switch over to usb 3.0, and the phone immediately dissapears from my pc.
Switch back to 2.0, and it reappears.
Is this happening to anyone else?
Maybe you have a faulty usb 3.0 cable. Try with a different usb 3.0 cable. If it's not the cable try on different computer. After that remains only one possibility: a faulty usb connector which means service. BTW you have usb 3.0 drivers installed on your w7?

Yeah i have a problem with the usb 3.0 too..
When i connect my phone via usb 2.0 it works fine but when i connect it via the usb 3,0 its still only shows up as a usb 2.0 device and the both only charge at 98ma :-/ brand new usb 3.0 cable. unistalled usb 3.0 drivers still no luck.

I've got this issue as well....
except when I attempt it on my work PC with W7 x64 it works in USB2.0 and USB3.0 mode. At home on my W7 x64 build it shows up under my computer in USB2.0 mode but disappears when switching to USB3.0 mode....
tried reinstalling drivers and all that jazz and no luck.
tried two USB3.0 cables and neither work on my home rig. i'm stumped
Plug in another USB 3.0 device such as a memory stick into your computer to determine whether the issue originates from the phone/USB cable or your computer. From what you described we cannot identify the root cause!

I had this issue too, then found it was my motherboard being the issue, i turned xHCI to on instead of auto (in the BIOS) and now when i connect my S5 with USB 3.0 cable the option for that mode will show on the phone.
Auto should work but it didn't seem to allow the S5 to trigger it, maybe because the S5 defaults to USB 2.0 and then you say to it to use USB 3.0
I do notice when switching modes the phone will vasish from the computer and then after a moment or 3 show up again

fiddled with bios settings on ASUS mobo... still no luck
a) Click on “Start” and Right Click on “Computer” and select “Manage”.
b) Now select “Device Manager” and Right Click on the individual “USB controller drivers” and select “Uninstall”.
c) Restart the computer and check if the issue persists.
if the cable is a cheap one that claimed to be usb 3.0 from eBay bin it and buy one from a decent retailer or Samsung
thanks for the ideas, tried device manager uninstall and reboot. still no luck. I"m using the provided samsung usb 3.0 cable so no issues there. very frustrating I cant use my phone connection to it's full potential

Old thread I know but here is what seems is the answer.
It seems when first connecting the usb it always defaults to usb2, but then can goto the usb settings on the phone afterwards and switch to media usb3 mode. I have not found a way to make it default to usb3 mode.

Appreciate the post but the issue wasnt actually switching into usb3 mode. That I knew how to do, it was that when I do switch the phone to USB3 mode it disappears from my file explorer and I cannot access the phone storage media unless I switch back to USB2 and then it pops up again in file explorer. I still havent found a solution and have come to the conclusion it is a hardware issue likely tied to my motherboard and have just accepted it and used it in it's limited form
I don't even see any option on my S5 to switch to USB3.....
Is this option device-specific?? I have the international version SM-G900H
Edit: never mind....the cable I had was a fake....
I tested my S5 with a cable from a USB 3.0 external hdd and it worked...

So are you saying that if the cable is faulty (or in other words, USB 3.0 is not achievable with the current connection) that the USB 3.0 option simply does not appear on the phone? That may explain why I am also only seeing MTP or PTP with a 3.0 cable and hub
Reading these replies and I still don't have a solution.
I have a Lenovo P50 ThinkPad and I normally connect my S5 via USB 2.0, but I'm wanting to transfer about 20gb of files off my microSD card to my machine. When I connect with 2.0, I can't even get the entire folder to show in the navigator window.
I tried to connect to the 3.0 ports, which I use with my external HDD with no problems. I'm even using the same cable.
And yes, it's a legit 3.0 cable.
Still no solution...
Did you find a solution?
Whenever I plug my G5 Plus to my computer (Windows 10) the phone starts charging but I cannot see it as an external hard drive on my computer. When I slide down the notification's bar there's nothing there for me to choose from regarding usb functionality. I've tried out 4 different usb ports and the same happens all the time. Any thoughts?
Just "fixed" it. I was using a regular usb cable. When I plugged the usb cable that came with the G5 it worked. I plugged it back with a regular usb cable and the issue reappeared. Does anyone know what type of usb cable does the G5 plus come with so I can get more?
Hello guys, here is the bug I experience
First of all i'm sure the cable isnt guilty as I tried two different cables, with one of them being new, getting the same result/bug
Whenever I plug something to my usb type-c port, it can ONLY and ONLY charge !
When i plug the phone to a PC, it won't recognize a phone is plugged ! It charges, but I don't have the window where u can choose between MTP, Charging,...
Of course I have enabled : USB Debugging, and switched from "Charge" to "MTP" in dev options
Even the USB otg doesn't work (with "OTG stockage" enabled ofc)
From times to times I could connect the pc to the OP5, but by plugging / unplugging the cable like 20 times... And now it's worse as it doesnt work at all !
It used to work perfectly in the past , is it possible the system can bug to the point this bug appears ? Is the type-c port broken ?
I have the same problem, the USB port can only do slow charging. It doesn't connect to PC/Mac and doesn't dash charge either. Taking it to service center as i'm pretty sure it's a hardware issue with the USB port.
Try downloading OnePlus USB drivers on pc you connected device to. https://www.androidfilehost.com/?fid=673368273298966498

MTP should work without those.
No it's not an issue with the drivers. The phone used to get detected fine and would do dash charge properly earlier, it suddenly stopped working.
I visited the service center, they confirmed my suspicion, it was an issue with the USB port module. A hardware issue where some of the pins on the USB module stopped working for reason, and as a result phone wouldn't receive connection from the cable. They replaced the module for me and the phone works properly again.
Can anyone suggest how to make windows 10 recognize the phone when connected via USB cable?

Which cable are you using for connection to the computer? the cable that comes with the phone is for charging only, you'll need a data cable for connection.
Some users have reported issues when flashing or sideloading using a USB 2.0 cable. The cable included with PH-1 is USB 2.0 and is primarily intended for charging. If you're flashing or sideloading PH-1, we recommend using a high-quality, spec-compliant USB 3.0 (or higher) cable.
ive used both 2.0 and 3.0, but never the 3.1 USB C style. never had an issue, but some of the cables look premium and are cheap crap that connect and disconnect on a whim because the pins arent contacting unless the cable is perfectly straight
I'm using this cable: https://www.amazon.com/gp/product/B01N5KL10L/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1
It is supposed to be a data cable and looks pretty decent.
Are any special drivers required ? ( I have installed the USB driver found on the Essential support page but no dice)
I have those same cables, they are a bit touchy when it comes to staying connected especially in a USB 2.0 port. Make sure you're using a 3.0 port and once it connects, don't move it much. Not a great solution I know but what can you do.
I tend to leave Device Manager open when I install new hardware. It often helps understand the sequence of things. Do you hear the Windows Device Connected Sound? If nothing is showing up there, it's the USB cable
Well.. I got my phone last Wednesday and I just got the issue when I got USB3.0 to USB C cable last Friday. (my main PCs do not have USB-C port)
The symptom is;
connecting USB cable and change connection mode to "file transfer" or MTP, it looked going to connect, but actually failed or disconnected when I tried browse the device or copy files.
After few research, I could resolve the issue.
Here are the what I did.
First, I have to download and install USB driver from Essential home page. (check "Essential Developers" page. I cannot add link here yet because I'm newbie here.)
Second, Now I got connection, but still the connection was unstable especially when I copied big files (about 200~300MB or more). The issue could be resolved after turning on "Disable USB audio routing" option in "Developer Options". (You should enable the "Developer Options" first)
Third, Now I have no problem on Windows PC connection, but I got a problem with Ubuntu 16.04. And I have found the it happens only when I connect it via USB hub. After connecting to PC directly, the issue has gone.
I have no problem on USB connection with my PCs now.
