MicroSD cards and your Galaxy phone

Running out of room on your phone? If you have a microSD card in your phone, it lets you expand memory space and exchange pictures, music, or data with microSD compatible devices. It's a must for that catalog of pictures or songs you've accumulated over the years.

Note: Available screens and settings may vary by wireless service provider and software version. Samsung Android phones do not support the Adoptable storage feature.

MicroSD card types

Unless you are a tech wizard, you probably aren't aware that microSD cards come in multiple classes. Other than storage capacity, they have different things that separate them. Some also come with extra features that give them distinct classifications.

microSD Card Classes

  • microSD cards have capacity up to 2 GB.

  • microSDHC (High Capacity) cards offer capacity up to 32 GB.

  • microSDXC (extended Capacity) cards have capacity from over 32 GB and up to 2 TB.

  • Each type of card has a speed rating of 2, 4, 6, 8, or 10, from slowest to fastest.

While you can use any class of microSD cards in your phone, the microSDXC card is recommended for high-resolution video recording, due to its large storage capacity and high-speed read/write capability.

For less demanding use, such as still photography, regular microSD or microSDHC cards will be sufficient.

Insert the MicroSD card

MicroSD cards give you tons of space on your phone, but they are really tiny. Just be careful not to drop or lose the microSD card. Learn how to insert one in two easy steps.

Note: Not all phone models support microSD cards.

  1. Insert the ejector tool (which comes with your phone) into the hole in the SIM and microSD card tray on the top of your phone. When the tray pops out, pull it out of the phone.

    Note: Be careful not to insert the ejector tool into the microphone hole, which is also on top of your phone.

  2. Carefully place the microSD card into the larger opening in the tray and insert the tray.

    Note: The SIM card slot is the lower, smaller opening.

Inserting a MicroSD card

Transfer media to a MicroSD card

No need to hire a moving crew; just transfer your files to a microSD card. You can also use the options in Device Care to help clear space.

First, insert your microSD card, navigate to the Samsung folder, and then tap My Files. Find the file(s) you want to move, and then touch and hold the file(s). Tap Move or Copy at the bottom of the screen, and then navigate back to the My Files home page. Tap SD card - this will only show up if you have a SD card inserted. Then, tap Move here.

Note: You can only move or copy files this way in the My Files app. You cannot move or copy files to other apps, such as Gallery.

Move apps to microSD card

Before you relocate an app to a new storage location, make sure you have a microSD card inserted. Otherwise, your apps will have nowhere to go.

Navigate to Settings, and then tap Apps. Swipe to and select the app you want to move. Tap Storage, and then tap Change. Choose SD card, and then tap Move to change the app's storage location.

If you do not see the Change option available, you can't change the app's storage location. For example, preloaded apps cannot be moved.

Encrypt or Decrypt SD card

If you use removable storage on your phone, you can protect your files by encrypting the SD card. Encryption converts data from a readable form to an encoded version that can only be read on the device that was used to encrypt it. Even though it sounds high-tech, it’s easy to encrypt files stored on your memory card on a Galaxy phone.

Important: If your phone is factory reset with the microSD card encrypted it will no longer be able to read the microSD card. Decrypt the SD card before resetting or using with another device.

From Settings, search for and select Encrypt SD card  or Decrypt SD card. Tap Encrypt SD card or Decrypt SD card. If you set a lock screen, you will be required to enter your credentials before your phone encrypts the files stored on your memory card. Keep in mind encryption can take several minutes or more, depending on the size of your SD card.

Note: Make sure to connect your phone to a charger while the encryption or decryption process is running. You will not be able to use the microSD during this time.
