Questions about USB connection and MTP/PTP transfer - Galaxy S III Q&A, Help & Troubleshooting

Hi,
I'm pretty new to the SGS world and it's the first time I have a phone with MTP/PTP mount when connecting to a PC.
1) Is it safe to "hot" unplugg the SGS3 from the PC? I can't see any unmount button/option on the device
On my previous phone, with "normal" USB connection, I would unmount the phone first before unplugging it from the PC, otherwise I might risk loosing some data on my sdcard (already happened to me).
2) Is there any way to speed-up file transfer between PC <-> Internal SD card, because it is sooooooooo slooooooooooow!

There is no usb option with device... If you want though then there is a app which requires root..
You can unplug it whenever you want..
I don't know how you can make the transfers faster

P500 - way to transfer apps/sync using USB

Ive read that using the usb cable to transfer stuff sometimes corrupts the SD Card if proper unmounting procedures are not followed. Someone pls list the step by step way to disconnect your phone from a PC. Also does it require any settings changes in the phone itself before and after using with the PC?
In system tray, right click and select unmount of device, then turn of mass storage mode on phone. Thats all.

sd card is being used as mass storage - sd card empty now!

guys, big issue here
On my wife's phone, she tried to take a picture and all of the sudden she got an error "sd card is being used as mass storage". now she cannot locate any of her files on the internal storage. as a matter of fact she doesn't have sd card. I checked under settings > storage and all I see is usb storage avaiable & used is at 11.50 gb.
also all backups are gone
can anyone help?
That happens when the phone is connected to your PC, if the PC is using it then you can't see it on your phone.
1. Make sure you aren't connected to your PC via USB.
2. Reboot the phone.
3. If still no joy then try a factory reset (there are probably other ways to fix this, but this is the simplest and noob friendliest way)

That solution worked perfectly for me (reboot). Thanks.

USB Mass storage?

How do I enable USB Mass storage mode instead of the stupid MTP og PTP?
Regards,
BTJ
Not sure if this works for the SGS3 but it worked for the SGS2:
Bring up Settings.
Click More… (under Wireless and network).
Then select USB utilities ~ Set USB cable connection mode.
Select Connect storage to PC then.
Connect USB cable from phone to PC.
Select Turn on USB storage.
That’s all.
Sorry, no such settings in SGS3, we are stuch with MTP or PTP... Don't understand the logic behind removing USB Mass storage mode!! Both MTP and PTP are slow as hell and there is no support for S3 in libmtp at the moment to make matters worse... If I had known this, I would have reconsidered my choice of buying a SGS3.....

Like the Nexus, /sdcard is mounted at /data/media (IIRC, mount point could be different), meaning that internal data and the internal sdcard space share the space, rather than being split. UMS removes access to the device that is mounted from the phone, so it cannot be used when the sdcard is shared in this fashion.
I thought libmtp worked? I've been using adb and a GUI for shifting lots of files, qtadb

Seems to be a problem with both SII and SIII... But I will check out qtadb, thx...

So am I reading this right. You can't plug a USB cable in, the SD card appears then in explorer?
I have a sensation XE at moment and use this a lot for transferring files at work/home etc.
So can I not access my files normally now that I copy to SD card, eg docs etc?
Nope... But it sounds like you are using Windows so then MTP will work, kind of like you are used to...
BTJ
The idea about using MTP is it allows you to continue to use your phone without disruption, loading Mass Storage un-mounts the sd from your phone.
However I do think we should still be given a choice
Yes, I guess I understand the idea... What I don't understand is why they have removed the choice we used to have.... :-|

I stil don't have an S3, but am a little confused on the MTP etc. Also I use a Mac and a Windows PC.
So when you plug in an S3 on a Windows PC, what does it do in MTP mode? just still allow you to drag/drop files? does the S3 come up as another drive or something in explore?
Also anyone with a Mac, how does this work?
cheers
This might give us some insight on why no USB Storage.

I think I got the jist of that article lol but does this mean android developement were looking for devices to have either internal storage or sd storage but because the SG3 has both its sort of screwed things up a bit?
So UMS might be released in a later patch to allow easier access to added SD storage? Or does the current setting allow access to both storage thru windows pc?
Soz if I come across as a noob I havent got sg3 yet but planning to get one in a few weeks for upgrade and Ive been trying to get the low down on positives and negatives before I get the phone
Keep things simple!
Please can someone answer this simply.
Can I plug in the device into my mac/pc and just transfer any file to the micro SD card whilst it is in the phone?
All I want to do is to be able to put avi files on it as samsung kies or doubletwist doesn't seem to suppor them...
A yes or a no with and explanation would be great ta!!

yes you can easily do that. No issues in that. Simply treat it as a normal pendrive in such a case.
sorted!

Thanks for the help. Although I figure out what everyone was talking about.
This is how I did it (maybe this will help others noobs as well):
You will need the 'Android File Transfer program' --> google search it!
1.Connect phone to PC (you will see usb icon at the top of the screen)
2. Pull down the notification centre.
3. Touch the usb thing.
4. Click PTP mode
5. Open the file transfer program
BOOM! Rock on nerds!

I am on windows 8. how do I view the SG3 sd card files?
Thanks!!!
Use the popular SGS3 UMS App.
Ext SD Card reading is supported, you can't move files through internal sd card and Pc.
Use bluetooth for that.
I've had the same problem many times after changing and testing new ROM's.
You can restart your computer and phone - has worked for me before.
Change ROM - this has worked for me, seemed like a particular ROM didn't like my PC setup / drivers whatever and refused to connect!
Change cable - they don't last that long, I've had to replace 4-5 since my HTC Desire days - all that plugging and unplugging can bust them - they always still charged, but no PC connection.
Try a different USB port - You never know!
Uninstall the drivers on your PC for your S3 - reinstall - use the SDK drivers - or from KIES. I seen users report that the change between a ICS ROM and a JB ROM and vice versa can cause issues, not sure if applies to you.

Hi.
I have my Galaxy S3 for some time now, and i want to transfer some music to my phone.
I have an SD Card with 64gb and of course, a computer
now what happens is that i start copying some music to my phone but after a few the phone simply disconnect and connect, which makes the file transfer very hard. (unless i'm gonna move song after song...)
Obviously this is not how the phone should work so this is why i am here.
Try Kies Air or Airdroid which are wireless transfers.

That happened to me too but only one time while transferring 5GB of music from my computer to my SD card so it wasn’t terrible. You can use the tools mentioned by sriram231092, or put your files on any of your clouds storage, then download them to your phone and transfer them to your SD card.
Edit: I found out reading Boeffla-Config Settings that if you have Boeffla Kernel, you can change the USB connection as UMS on demand, which simplify data transfer:
http://www.boeffla-kernel.de/non-joomla/en/bc-settings.html#Overview said:
1.1 UMS Mode
Default: Off
Expected impact: Make external phone SD card available as drive on an USB-connected PC
With Android 4.x versions, Google decided to only use the MTP (media transfer protocol) for communication when you connect your device to a PC.
This prevents the memory to show up as a drive but only as a device.
By toggeling this checkbox, the external SD card gets unmounted internally (not accessible from the phone anymore) and the protocol is switched from MTP to UMS (usb mass storage) to make it appear as a normal USB drive on your PC. This simplifies data transfer a lot.
Please do not forget to untick this again after you finished using the connection, so it gets mounted and visible on your Android device again.
Note: When this does not properly work, it is most likely an issue with USB drivers installed on your PC.
