2. Go to Settings > Security > More settings > Encryption and credentials .

3. Touch Encrypt memory card and follow the onscreen instructions to encrypt the memory card.

   During the encryption, do not restart your phone or forcibly remove the memory card. Otherwise, the encryption may fail or data may be lost.

To decrypt a memory card, touch Decrypt memory card and follow the onscreen instructions to decrypt files on the memory card. Formatting a memory card can also decrypt the memory card, but will erase all data on the memory card.
