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 resets, encryption
also starts. If you stop the encryption arbitrarily, the data may be
damaged. Be sure to wait until the reset is completed.
KnockON

• This option is available only on the Home screen provided by LG. It may
not function properly on a custom launcher or on the Home screen
installed by the user.
• When tapping the screen, use your fingertip. Do not use a fingernail.
• To use the KnockON feature, make sure that the proximity/light sensor
is not blocked by a sticker or any other foreign substance.
Turning on the screen

• Tapping the top or bottom of the screen may decrease the recognition
rate.
