Samsung tablets are easily among the most popular tablets on the market. But in terms of specs and functionality, one glaring problem is that depending on the model you choose, they tend to have limited storage space. This of course limits room for your apps, pictures and other files. Creating more space requires purchasing an external SD card to provide additional storage. SD cards today have matured to storage devices with up to 1TB capacities. But in most cases, the default storage is the tablet’s main storage. So, how do I make an SD card my default storage on Galaxy tablet? Let us show you.

How Do I Make SD Card Default Storage on Galaxy Tablet?

An SD card is always helpful, especially if you use your Galaxy tablet frequently. You can save photos to the card, transfer apps, and use the tablet’s external storage to store a lot of files.

There are two ways to make your SD card the default storage on your Galaxy tablet. Here’s how it’s done:

Option A

There’s a chance that these instructions won’t work on your device. If that’s the case, it’s probably because the device is running an older version of the Android software. Alternatively, you scroll down to option B.

  1. Choose Storage from the Settings menu on your tablet.
  2. Select SD card. Choose Settings from the three-dot menu at the upper right of the window.
  3. Select Format as Internal Storage. This option will reformat the SD card and set it as the tablet’s default internal storage.
  4. Select Erase & Format
  5. Restart your device
  6. The SD card will now be used as the tablet’s default internal storage.

Option B

After the format is complete, only your device will read the card. So to save time, the best option is to start the process with a new SD card.

  1. Select Storage & USB from your device’s settings
  2. You’ll be able to view your SD card’s information. This screen will give you the choice of formatting your SD card as the device’s internal storage.
  3. Select to format the SD card
  4. Restart the device after that. The tablet’s primary internal storage will now be the SD card.

It’s essential to keep in mind that if you format your SD card, all of the files on it will be erased. Therefore, if you have any files you want to save, make sure they’re backed up.

You can make a backup of your files by transferring them to your laptop or an external hard drive. You can also use a cloud service like Google Drive to back up the files.

Formatting an SD Card Using Your Laptop

You can also use your laptop to format your SD card for your Galaxy Tablet. If you don’t have a slot on your laptop to insert the SD card, you can buy a USB memory card reader that supports SD cards.

Simply insert your SD card into the adapter and connect it to your laptop. The adapter will display as a new disc drive on your laptop. Here are other instructions you can follow.

To format your SD card, follow these steps:


  1. Connect the SD card to your laptop.
  2. Find the drive letter for your SD card in File Explorer. Right-click it and choose Format.
  3. Change the File System to FAT32 if your SD card’s storage is less than 64 GB. Change the File System to exFAT if the storage is 64 GB or larger.
  4. After that, click Start.
  5. To start formatting the card, choose OK. A message will pop up indicating that the data in the storage will be deleted.


  1. Using a Finder window, navigate to the Applications folder.
  2. Launch the Utility folder by scrolling down and clicking it.
  3. On the left side of the screen, locate and select your SD card. Make sure you’re looking in the left-hand External section. It will most likely appear titled unnamed or no name.
  4. Choose Erase. You can find it between Partition and Restore at the top of the page.
  5. From the pop-up window, select a new format.
  6. To format and wipe your SD card, select Erase.

How to Transfer Apps to the SD Card

Galaxy tablets allow users to transfer or install apps to an SD card. Follow these steps below to learn how to do it:

  1. Unlock your tablet and open the settings.
  2. Tap the app menu.
  3. Search for the storage setting option. Afterward, select storage or change destination to adjust the storage of the applications.
  4. You’ll notice that you’ve transferred your downloaded apps to your tablet’s SD card.

This process is reversible. If you choose that you want the data back on your internal storage, you may do so by reversing the procedure.

What Kind of SD Card Do I Need for My Galaxy Tablet?

An SD card is a long-term commitment. Before you change your storage to an SD card, make sure the SD card you want to use is compatible and has a high capacity.

Storage Size

The maximum storage size that your tablet can support is determined by the model. Be sure to check that first.

Ideally, you should purchase an SD card with the highest memory capacity. A memory card with a capacity of 64 GB or higher is sufficient.

Typically, most SD cards have a storage capacity of 128MB to 2GB. SDHC cards have a size range of 4GB to 32GB for instance. And SDXC cards have a capacity range of 64GB to 2TB. And finally, SDUC cards have support for up to 128TB.

Good Brand

Purchase a Samsung memory card for optimal performance. If not, make sure you buy a good memory card from a reputable manufacturer, such as Sony or Transcendent.

Read and Write Speed

While the card’s capacity is vital, the speed of an SD card should also be considered. Each SD card has a read speed and a write speed. Based on how you plan to use the SD card, you should prioritize the read and write speeds.

For video recording and taking photos, for example, you’ll need a fast write speed. The same goes if you want your photos to be in high resolution. Therefore, if you’re going to buy an SD card for photography, be sure it has a high writing speed.

Keep in mind that if your SD card’s writing speed is less than your camera’s speed, the camera will stop recording.

UHS Type

The speed also varies based on the card’s UHS type. There are two types of UHS cards: UHS I and UHS-II. UHS stands for Ultra High Speed. The configuration of the connectors on the back of the card is the main difference between the two types.

UHS-II cards are intended for storing and backing up big amounts of photography data. For this you will need quicker read and write rates. It’s worth noting that you need a specific type of slot to use the UHS-II cards.

UHS-I cards have slower speeds but are much less expensive to purchase.
