[Tutorial] How To Connect USB Flash Drives With Samsung Galaxy S III

If you recently bought a Samsung Galaxy S3, you have probably noticed that it does not have the USB Mass Storage Mode or UMS. In this tutorial I will show you how you can bring this feature back to your Galaxy S3 without rooting your device or loosing your warranty easily.

Before proceeding further, make sure you backed up your data. Once you data is safe and secure continue following the steps below.

Step 1: First you will need to download a small app on your computer hosted in Dropbox.

Step 2: Once the app is downloaded, connect your Galaxy S III phone with your computer using USB cable. Copy the downloaded app on your phone.

Step 3: Now locate this app on your phone and tap on it to start the installation.

Step 4: Follow on-screen instructions to install the app.

Step 5: Once the installation is finished open the app and select which mode you wish to use (you will have to choose UMS mode to enable USB mass storage support) and you are done.

Easy and simple, right? If you had any problems following the process or wish to share your opinion leave it in comment section below.

    This app requires rooting (look at XDA website)!!! You gave me hope there for a second – I installed n tried it but it gave an error when I tried mounting / UMS mode saying no root access. Don’t write articles that aren’t accurate.

    Sorry you’ve test jack. Error message confirms what the good citizens here and the fine people at XDA say …. got to have root access.

    i believe this app allows you to connect your s3 to a computer as if it
    were a usb mass storage device (as opposed to MTP or PTP which are the
    only stock options). This does require root.However there is no real reason to use mass storage as long as your windows/mac/linux supports MTP. MTP is more stable than mass storage and causes fewer problems. You do not have to root your new phone to enjoy it but you may have to update your old OS.
