Taking Screenshots - LG -K580 Guia Del Usuario

To encrypt the memory card, make sure that a screen lock is set using
a PIN or password.
Once memory card encryption starts, some functions are not available.
If the device is turned off while encryption is underway, the encryption
process will fail, and some data may be damaged. Therefore, be sure to
check whether the battery level is sufficient before starting encryption.
Encrypted files are accessible only from the device where the files were
encrypted.
The encrypted memory card cannot be used on another LG device. To
use the encrypted memory card on another mobile device, initialise the
card.
You can activate memory card encryption even when no memory card
is installed into the device. Any memory card that is installed after
encryption will automatically be encrypted.
