Precautions for device encryption
You can use the mobile phone lock on the lock screen to increase
your device's protection level.
• If the mobile phone lock is turned on and an incorrect password
is entered more than a specified number of times, the device will
automatically reset.
• If you forget your decryption password, you must reset the device
to use it again. A factory reset will delete all data saved before the
reset.
• Encryption takes place when the device boots for the first time
after a factory reset. Stopping encryption before it is complete may
damage data. For example, do not remove or insert the battery
while encryption is in progress. Wait until the process is complete.
SD card encryption
You can encrypt and protect data saved on the SD card. The
encrypted data in the SD card cannot be accessed from another
device.
