You can encrypt files stored on the memory card. Encrypted files can only be viewed and used on your device.

1. Insert a memory card into your device and ensure that the memory card has sufficient storage space.

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 device 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.

Encrypting and decrypting the memory card will not be supported if you are not logged in as the Owner.
