MicroSD cards and your Galaxy phone or tablet

Insert the ejector tool (which comes with your phone or tablet) into the hole in the SIM and microSD card tray on the top of your phone or tablet. If you have any issues removing or inserting the SIM card tray, service may be necessary. If you need a replacement SIM ejector tool, you may be able to get one from your carrier or an electronics retailer.

Important: Be careful not to insert the ejector tool into any of the microphone or speaker holes along the edge of your device. Look for the outline of the tray to make sure you're in the right place.

 When the tray pops out, pull it out of the phone or tablet.

Carefully place the microSD card into the larger opening in the tray - the SIM card slot is the lower, smaller opening. Then, reinsert the tray into the device.

Turn your phone off, remove the phone’s back cover, and then remove the battery by lifting it up from the bottom.

Insert the microSD card in its designated slot.

Note: This slot is right on top of the SIM card slot.

Then, replace the battery by sliding it into its slot. Replace the back cover and make sure it snaps into place.

To remove the microSD card, first remove the phone’s back cover, and then the battery.

Remove the microSD card from its slot. Then, replace the battery and the back cover.

Tap Encrypt SD card or Decrypt SD card.

If you have a lock screen set up, you will be required to enter your credentials before your device encrypts the files stored on the memory card.

Your device will begin the process of encrypting or decrypting your SD card. This can take several minutes to complete, depending on the size of your SD card, and the amount of data stored on it.

Navigate to and open Settings.

Tap More options (the three vertical dots), and then tap Storage settings.
