Unlocking the screen with a Knock Code
Unlock the screen by inputting the Knock Code you have created.
Input your Knock Code on the touch screen when the screen is turned
off.
• You can use your Knock Code, together with the KnockOn feature.
• If you enter an incorrect Knock Code more than a specified number
of times consecutively, unlock by using your backup PIN or Google
account.
• Make sure to use your fingertip when tapping the screen.
Secure start-up
Secure start-up overview
When you turn on the device, the screen is locked for security. Unlock
the screen by entering the current unlock method, such as a Knock code,
pattern, password or PIN. Until the screen is unlocked, you cannot receive
most phone calls, text messages, alarms, notifications, and more.
Precautions of Secure start-up
• If the password is entered incorrectly more than a specific number of
times, the device will automatically initialise. Be sure to remember the
password.
• If you forget your decryption password, you must initialise the
device to use it again. Initialisation will delete all data saved before
initialisation.
• Encryption takes place when the device boots for the first time
after an initialisation. 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 encryption is complete.
