Galaxy S3 Green LogoWith Jellybean 4.1 nearing its roll out on the latest SAMSUNG Galaxy S III GT I9300 device, it seems like most of the users are disappointed with one of the feature which doesn’t find place in the device. Yes you have caught it right, it’s the USB Mass Storage Mode (UMS). So, to keep things simple, we will be guiding you in the due course of this article on how you can easily infuse this option in your next generation Galaxy S III. In place of UMS option, users will have to make use of MTP which is also called as Media Transfer Protocol.

There are their own advantages of both these modes, but then for most of the users it’s like compatibility versus the preference. One of the major drawbacks is that not all the operating systems are compatible with the MTP and without the third party tools, things can only get messed up. All thanks to the XDA developer which has come up with this standalone application which can be applied to all the phones of Samsung Galaxy S3. So, for all those who wanted to get rid of the instructions of MTP, can proceed to follow the instructions mentioned in this tutorial.

  1. Ok I figured it out. The problem seems to be the wire you’re using. you can’t just use any wire that fits you MUST use the wire that came with your phones charger! Hope that helps!

  2. Wow, what a mess.

    First of all, the APK you want us to use only works on rooted phones. You claim this procedure works on unrooted phones. Apparently you are wrong, or something is missing.

    Secondly, for people who can’t connect their phone to the PC, which is why they want to activate Mass Storage, they can’t transfer any files from the PC to the phone.

    If someone knows how to make this work on an UNROOTED phone, please let us know.

  3. Pedantic_Douchebag

    I had mass storage working on my phone out of the box (it’s a GT-I9300 made for the French market, bought unlocked on eBay in the US). After 4 weeks, suddenly it appeared not as two removable drives (1 for the phone memory and 1 for the SD card) in the Windows 7 “Computer” window, but instead as “GT-I9300 Portable Media Player” which at first had no contents. Alarmed, I wound up here, where I ran up against the same chicken/egg problem, but figured out the way around it: unmount & remove my SD card, put it in my computer’s SD card slot, copy the *.apk file to it, then put it back into my phone. However, just after unmounting my card (done via a switch in the Storage menu settings), I had an intuition to re-mount it and then check Windows Explorer again. Sure enough, the GT-I9300 Portable Media Player now had contents, my two drives, the phone and the SD card, with access to all the files on both. In case this helps someone, try it, and if not, go ahead and run the .apk file once you’ve tx’d to your SD card. Good luck!

  4. I found a better way to enable usb storage on note 2, s3 and s4 right here http://goo.gl/RLD5oP

  5. Terribly confused. I feel so inadequate with my new galaxy 3. I have copied the file several times and I can see that it has downloaded to the phone but how do I get to the Mass Storage??? How do I get the file to open in apk. format? What is really going on?? Please help a technologically challenged person. Thanks

  6. Hi,
    I have the same problem with my gt-i9105p ics4.1.2 : no ums option !!!
    is your *.apk compatible with my gt-i9105p or only with a S3 ?!!

    best regards

  7. The instructions say to “Download the USB Mass Storage (UMS) APK file to your computer” but then the instructions say “connect your phone to computer with the help of USB cable to copy this APK file in your device.”. Hmmm… if we can’t access the phone as a USB device, how are we supposed to copy the APK file from our laptop to the phone? Doesn’t make sense. Chicken and egg problem.

    • Ditto…. hoping to find an answer I continue reading…..

    • It’s really easy download the apk file to your computer, after that go downloads of your computer and you will see the apk file, now connect your phone into the computer and open the download folder on your phone…now go to the download folder of the computer find the apk file transfer it to your download folder on your phone and then disconnect your phone, after that go open your phone and go to the download folder your will see the apk file, double click to instal it and then Google will ask you if you want to accept the download from unknown sources click yes and it will start downloading, when it’s done you will see it. Hope this helps….
