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.

dear wisechap
2 possibilities - if your wire has 2 cables, then one is for charging and one is for data.
the other option is that you have to terminate your relationship with the phone and establish a new one. if this is possible, then likely you will be asked wehther to delete sync files between the two or not. you may choose not to delete.
hope this helps.

This has NOTHING to do with charging.
Yes, check you didnt tick the box "do not charge when connected to a PC" in the power options.
If your battery is sufficiently depleted them the low output from your USB port may be too low to start the charging process.
Attempt the charge from wall charger and then try not to let the battery drain too much.
It is also posible that the power output from your USB port on your PC is defective, Usualy there is a fuse somewhere mounted on the mainbord and looks like a resistor. You can easy check this by using an other PC and connect the phone to that one. You don't need to intsall the ActiveSync on that PC to check. When that one is charging your batery..... Well you know.....
Oh, there is an other posible selution. Turn on your PC Joking
Are you plugging your phone into an external usb hub or directly into a usb port on the back of your computer?
I recently upgraded from an old tmo Wing and it would charge just fine off a port on my external usb hub. When I plugged my HD2 into the same port, it would not charge. If I connect my HD2 directly into the back of my computer, it charges just fine.
I'll be looking for differrent hub that provides more power and will allow for better charging.
if you POWER OFF the phone and it dose charge (orange led should appear near earpiece)
then your pc's usb and your usb cable are fine.
to fix,
go to 'SETTINGS'
and then at the bottom tap on 'ABOUT PHONE'
then tap on BATTERY'
then 'un-tick' the box that says "When the phone is on, do not charge the battery when connected to a PC"
USB Debugging mode might be on. I rooted my phone and forgot to uncheck that box and once I did, it started charging again.
How do I Stop it charging from the computer on Gingerbread Hyperdroid

I setup a self-powered USB2.0 hub which has a 2.5AMP power adapter. I used a dual male (split) to single female USB cable and plugged the TAB USB cable into that.
This same dual cable & hub works fine to power an external USB hard-drive which won't work with just a single cable for power. I would think with 2+ AMPS it should charge the TAB "normally" (with no "x" on the battery indicator) but it does not, the "x" remains. All other devices have been removed from the hub.
Anyone else been able to get a normal charge off a PC or USB hub with a split cable? It's such a pain to have to put the TAB on the wall charger then switch it back to the PC.
when the screen is off the device charges, despite what the battery display says.

Correction, it trickle charges. Very slowly.

I understand that but I was under the obviously incorrect impression that if you used a double male USB to single female USB cable you would get a normal charge since there is more power available. Is the charge rate dependent on the TAB seeing power on a specific pin of the cable telling it that a charger is connected and not a cable to the PC? I'm connected to a self-powered hub with a big 2.5amp power supply and nothing else connected to it.
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?
I have a new desk job and I've been abusing the new T-Mobile free music data to listen to Pandora all day which is killing my battery.
When I plug my Note 3 into a USB 3 Port it defaults to USB 2 mode. I know I can go to "USB computer connection" in settings and change it to "Media device (USB 3.)" to get it to change over. Does the fact that I have to manually change it over to USB 3 for data mean that I'm also not getting USB 3.0 900mA to charge with?
An additional frustration is that it is hard to test that because if I don't use the USB 3.0 to transfer data then it eventually "falls back" to USB 2 mode automatically. Is there any way to make it stay USB 3 when plugged into USB 3?
Thanks!
It defaults to 2.0 because a lot of computers and laptops that people have dont always have usb 3.0, if you can do it you have the option to switch

Fair enough, but it seems like the Note has the ability to detect that it is plugged into a USB 3 port because it only offers the USB 3 media mode when it is.
Also, any ideas on whether the data mode affects the ability to charge at the higher USB 3 900mA instead of the USB 2 500mA?
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.
