Secure start-up settings
For additional security for your device, you can enable the Secure
start-up option when setting a screen lock.
• You cannot use all functions, except for emergency calls, until you
unlock the device.
• If you forget your decryption password, you cannot restore
encrypted data and personal information.
Precautions for the secure start-up feature
• If you forget your decryption password, you cannot restore
encrypted data and personal information.
• Be sure to keep your screen lock passwords separately.
• If you enter the screen lock passwords incorrectly more than
the specified times, the device automatically resets itself and
the encrypted data and your personal information are deleted
automatically and they cannot be restored.
• Be cautious not to enter incorrect screen lock passwords more
than the specified times.
• When you turn on the device right after the device reboots,
encryption also starts. If you stop the encryption arbitrarily,
the data may be damaged. Be sure to wait until the reboot is
completed.
