[Q] how to disable USB PC CONNECTION?

So here is what I'm trying to do... I want to disable the usb pc connection, because I have noticed that my phone charges very slow when connected to the computer, compared to when I have it charging to the wall outlet...
is there anyway to disable this feature so that I can just have my phone charging through the computer without enabling the pc connection?
I know on older previous versions of Android, when plugged to a computer you would get prompt with some options to choose (mass storage, kies, charge only, etc)
Is there anything similar available for the i337?

The data connection to the PC isn't causing slow charging.
Your PC's USB port most likely only puts out 0.5A, while the wall charger puts out 2A. (my numbers may not be exact, but the theory is the same).

Exactly as stated above. USB 2.0 only allows 500ma of charging power vs 2.0amps (2000ma) for the charger that is supplied with the S4.
I wish phone makers would start getting with USB 3.0 Standard. If they had a 3.0 connector on the USB cables supplied, USB 3.0 can supply up to 1.5amps, and potentially up to 5amp.

As an aside: the SGS4 only allows for MTP and PTP connections...
There is a way to allow Mass Storage mode, but I wouldn't recommend it, so I won't provide any more details on that.

Phone is charging but isn't recognized.

Hello, I've recently bought LG G2 (d802). Everything was fine but since two days when I plug it into the PC, the phone charges and there is "slow charging" in the status bar. I've tried these things and nothing worked.
- used a new USB cable apart from the cable given the G2 box.
- used the OEM cable on another PC.
- uninstalled LG Mobile United drivers and reinstalled.
- uninstalled drivers and connected the phone, to no avail.
- different port
- cleaned mUSB port on the phone. (You know, just blowing air in to it )
- tried unchecking MTP, rechecking it. USB debugging off to on and vice versa.
And also I've rooted the phone and currently on Rayglobe 2.3. I'm worried if it's a hardware problem and since my warranty is void, am I screwed? Please help me.

If you charge through USB, it is normal for it to say Slow charging. Are you on Mac or Windows.

Sorry but what exactly is the problem you are experiencing? Your phone is charging isn't it?
The slow charge icon is pretty self explanatory, it's indicating that the power output from your source isn't strong enough to charge your 3000mAh at the normal desired rate; it's going to be a "slow charge".
This is normal when charging from a usb port on a computer, their power output isn't anything near that of your mains outlet. It is also the case with every phone you try to charge via your PC's usb port .. LG are just notifying you that it's going to be a slow charge.
I'm not sure if this will be the case with USB 2.0/3.0 connections but everyone will get that message if using a normal usb port.

There is a setting in the phone that lets you choose HOW to connect to your computer, for example "charge only" or "connect as an mtp device"

Well, I think my question wasn't clear. My PC is not recognizing the phone, no pop-up messages, no LG G2 drive. But the phone is charging. My question was not about the charging but my phone not being recognized by the PC.
I wanted to transfer Rayglobe ROM to my phone, but when I connected, there was no G2 drive. I'm on Windows 8.1 BTW.

Never used win8 so can't help you there, did you try different usb-ports?

[Q] question re quick charge and usb connections

if i have my edge recharging on a wireless charger (connected with samsungs own power supply and usb cable) then i'm guessing it's not a good idea to also plug the phone into the PC so i can copy some stuff on there?

USB Type-c port : bugged or broken ?

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.

USB charging port faulty?

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?
