If you have ever encrypted your phone or Tablet, you know how performance can degrade.

Note that in this tutorial we are using an unencrypted Galaxy Tab S2. In some versions of the Samsung firmware, you will be unable to encrypt an SD card from a device that has already been encrypted. Therefore, if your device is currently encrypted, and these instructions are not working for you, you will need to decrypt your device and then encrypt your SD card and, once more, encrypt your device.

  4. 4
    Once you have tapped 'Encrypt external SD card', the system will inform you that the SD card encryption is turned off.
    You'll be asked to enter a six characters minimum password that includes one letter and one number. Note that if you do not have screen security enabled, you will not be able to enter these characters.

    If you do not have screen security enabled, proceed to the next section.

  6. 6
    If you have screen security enabled, you can skip ahead to section on what to do if you have screen security enabled; or you can simply enter the six character password you'll use to encrypt your SD card, which we discuss in more detail below.

If You Do Not Have Screen Security Enabled

Screen security is more than just a pattern or four-number PIN. It's actually a real and true form of secure access to your system. You can just use a six-character PIN, or you can use a PIN and your fingerprints. In the steps below, we will just use a six-character PIN because it is easier to set up.

Was this helpful? Yes | No | I need help

  1. 1
    To set up a screen security pin, tap the bottom of the screen on 'SET SCREEN LOCK TYPE'.

  2. 2
    After tapping on the option, you will be asked to enter a PIN.
    Enter a four-digit pin at this point. Note that at this stage we are only setting up a pin for our device. This is not the PIN for your encryption.

  3. 3
    Tap once on 'CONTINUE'.
    Note that your PIN will automatically be set the moment you tap 'CONTINUE'; so, be sure you have it written down or memorized. In our example, we used 1234. We strongly suggest that if you are not familiar with this process or if that it is your first time doing it, then you follow similar steps and use a basic password until you have familiarized yourself with exactly how device encryption and decryption works.

  4. 4
    After entering your PIN and tapping 'CONTINUE', you will be taken to the screen-lock selection screen.
    Note that only high-security passwords or fingerprints are allowed when using device encryption. This is because other methods are much easier to break. In this case, we will set a high-security password for our device. Tap now on 'Password High security'.

  5. 5
    At this point, you will be told to enter six characters.
    The six characters should include at least one letter and one number. We will enter an easy-to-remember and relatively simple password, using 1q2w3e.

    Once you have entered your password, tap on 'CONTINUE'.

  7. 7
    You will then be asked to confirm your encryption password.
    As before, type your password. In our case, it was 1q2w3e. If you chose something different, then enter that and tap 'OK' to continue.

  8. 8
    After tapping 'OK', you will be taken to a screen asking how you would like to have lock-screen notifications set.
    We recommend not showing any notifications, which is the bottom option and which is selected by default. The reason for this is that if you are attempting to secure your device, it is a good idea to not allow any notifications. Sometimes an SMS notification will give away information you might have wanted to keep private. However, if you're simply interested in encrypting your SD card, but otherwise want to allow the device to be shown, then you may instead select 'Show content'. Whatever you select, tap on 'DONE' to proceed to the next screen.

If You Have Screen Security Enabled

if you have skipped the previous section because you already had a high level of security enabled on your Samsung Galaxy Tab S2, then you will want to follow these steps.

  1. 1
    Tap 'TURN ON' once to enable SD card security.

  2. 2
    Once you tap turn on the option, you will be informed that encrypting your external SD card will encrypt all files on the SD card.
    You must tap 'YES' or 'NO' to proceed. In this tutorial, we tap 'YES'.

    • If you tap 'NO', then only files which are created on this device will be encrypted.
    • If you tap 'YES', then all files are encrypted.

  3. 3
    Next, you will be given the option to avoid encrypting common media files such as AVI, JPG, or MP3.
    This means that videos and photos you take on your Galaxy Tab S2 will not be encrypted. You must tap 'YES' or 'NO'. In this tutorial, we have tapped 'NO'.

    • If you would like to encrypt these files, then you will want to tap 'NO'.
    • If you do not want to encrypt these files, then you will want to tap 'YES'.
    Was this step helpful? Yes | No | I need help

  4. 4
    You will now see a window confirming your SD card encryption and listing all of the choices you made previously.
    Review them and, if satisfied with your selections, click on 'CONTINUE'. If you do not wish to continue, then tap on the back button on your device to go back and change the settings.

  5. 5
    After tapping 'CONTINUE', you will be asked to enter and confirm your password.
    Note that this password is not the simple 1234 password we created earlier. This is actually the encryption password. In our case, this password was 1q2w3e. When you have typed your encryption password, tap on 'CONTINUE'.

    Was this step helpful? Yes | No | I need help

  6. 6
    After tapping 'CONTINUE', you will be taken to a warning window.
    It is very important that you pay attention to the settings in this warning window. Of particular concern is the fact that if you perform a factory reset, the decryption key stored on your system for files on your SD card will be erased. This means you will not be able to access or use those encrypted files again, but you will still be able to use the unencrypted files. The only solution you have to restore storage space in such cases will be to delete the encrypted files. Therefore, make sure that you turn off SD card encryption before performing a factory reset and unencrypt all files. With that in mind, tap one time on 'APPLY' so that you may continue.

    You will then be taken to a window where SD card encryption will occur.
    You will be asked to wait while the device is encrypted, and during this procedure, you will notice that there is an activity icon in the notification bar in the upper-left corner.

  8. 8
    When finished, you will receive a pop-up with the message that the SD card has been encrypted and that it is now available.
    Simply tap 'OK' to continue or, if you prefer, you may tap 'GO TO MY FILES'.

Additional Tips

  • Encrypting your SD card may seem like a good idea, but if you don't need to, avoid doing it. SD card encryption slows down everything on your system. It can result in the complete loss of your files if there is problem with your Galaxy Tab S2 that causes it to require a factory reset.

  • Use encryption with caution and make sure you back up your device regularly so you will still be able to access stored keys to retrieve locked or encrypted files later.

Questions and Answers

Galaxy S2 8" tablet will not let me encrypt my 64GB SD card?

I am following the instructions for encrypting my SD card (which I have to do to use it at all because I use work emails on the tablet and they insist on everything encrypted. Fair enough). But all I get when I start the process is an error message
