Encrypt Content on the Memory Card
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.
Set a SIM PIN Lock
A PIN is the identity code of a SIM card, and can be set as the SIM card lock. After you set it
up, you will be required to enter the correct PIN to unlock the SIM card every time you power
on your device or switch to a new device to prevent unauthorised access.
If you have entered a wrong PIN and exceeded the maximum number of attempts allowed to
unlock the PIN, you will need to enter the PIN Unlocking Key (PUK) then reset the PIN. If you
exceed the maximum number of attempts allowed to unlock the PUK, your SIM card will be
permanently blocked.
The PIN and PUK of your SIM card are provided by your network provider. The number of
digits and maximum number of attempts allowed to unlock your PIN and PUK are subject to
your network provider.
1
Go to Settings > Security > SIM PIN to enter the SIM PIN screen.
2
Enable SIM PIN, enter the PIN, then touch OK.
To change the PIN, touch Change SIM PIN, and follow the onscreen instructions.

Manage App Access Permissions
Apps may require certain permissions, such as the Location permissions, in order to provide
you with corresponding services.
However, some apps may obtain too many unnecessary permissions, posing potential risks to
your privacy and information security. You can monitor the permissions granted to each app
and deny those you deem unnecessary.
