Format Memory Card


You can use a microSD or microSDHC card (not included) to add additional memory space to your device.

Format a microSD Card


Note: When formatting an SD card, you will want to backup your music and photo files that are stored on the card because formatting the SD card deletes all the stored data.

1. From the Home screen, touch Apps Icon_Apps_8_3.png > Settings Icon_Settings_2_2.pngStorage Icon_storage.png.

2. Scroll down and touch Format SD card and follow the prompts.

1. From the Home screen, touch Apps Icon_Apps_8_3.png > Settings Icon_Settings_2_2.pngStorage Icon_storage.png.

2. Scroll to and tap Unmount SD card.

4. Insert the ejector tool into the hole in the microSD card tray on the side of your device, and gently press the tool until the tray pops out.

5. Remove the microSD card from the tray and insert the microSD card tray back into the device.

Mount a microSD Card


When you insert a memory card, it is automatically mounted (connected to the device) and prepared for use. However, should you unmount the card without removing it from the device, you will need to mount it before it can be accessed.

1. From the Home screen, touch Apps Icon_Apps_8_3.png > Settings Icon_Settings_2_2.pngStorage Icon_storage.png.

2. Scroll to and tap Mount SD card.

Advanced Users: Changing file systems


Important: The following information is for advanced users regarding NTFS and FAT file systems. It is explained with the assumption that prior experience is available and will NOT review basic information. As a result, certain terms and instructions may be found confusing. It is not recommended to continue if you do not consider yourself to be an advanced user. Click here to expand the topic.

Many external memory storage devices (E.G: SD cards, USB’s, external hard drives) are formatted as FAT file systems. This has nothing to do with Samsung’s onboard software, but can be changed. With the dramatic increase in file sizes and hard drive space, many users wish to move files larger than 4 GB. However, the following should be taken into account before altering file systems:

    •By default, Mac computers can read NTFS drives, but cannot write to them without help from external software or changes made by command prompt or terminal.

    •If an external device is formatted as NTFS, it is absolutely necessary to use the “Safely Remove Hardware” feature to remove the device. Failure to do so may corrupt the files it contains.

    •FAT is ideal for external drives because so many devices support it.


NTFS has more advantages than simply moving larger files. These include, but are not limited to, local and network security, better reliability, and better disc space utilization.

Note: The following instructions are for a computer running Windows 7. The steps for other operating systems will vary, but can easily be found online.

In order to change file systems, use the following steps:

    1. Connect the micro SD card to your computer (micro SD card to USB converter may be required).
    2. Under “Devices with Removable Storage” right click on the drive you wish to alter and click Format....
    3. Under File system click the drop-down menu and click NTFS.
    4. Click Start.
    5. Click OK to commence (all data on the removable disk will be lost).
