How can I lock the screen on LG G4?
LG G4 LOCK SCREEN BASICS
Your phone automatically uses a default Lock Screen to simply prevent unintentional function activation.
You can choose to secure your phone so that only you can unlock it to access your data, buy applications, and so on.
For added security to guard against unauthorized use, you can set a requirement (such as Knock Code, pattern, PIN, or password) that will need
to be entered to unlock it. You can also set no lock screen at all.
Note: Some Settings, Menus, or Icons may differ from that of your device depending on your software version and wireless
service provider.
Follow these steps to set an unlock sequence for the first time or after you disable a previously set unlock sequence.
① From the Home screen, tap Apps > Settings
> Display tab > Lock screen
② Tap Select screen lock.
③ Tap None, Swipe, Knock Code, Pattern, PIN or Password.
- None: No lock screen is enabled so the screen will never be locked from use.
- Swipe: A swipe motion in any direction on the touchscreen will unlock the screen.
- Knock Code: Create your own knock code. When the screen is off, if you tap the same sequence anywhere on the screen,
the Home screen can be accessed directly.
Read the tutorial and tap the NEXT button. Tap 3-8 times in the 2X2 grid shown to set your knock code,
then tap the CONTINUE button.
Re-tap your code and tap the CONFIRM button.
Note: Follow the on-screen instructions to create a backup PIN number in case you forget your knock code
- Pattern: Unlocks the screen using a pattern you draw with your finger. The first time you set an unlock pattern, you will see a tutorial with
instructions on how to create it.
Read the tutorial and tap the NEXT button. Draw your pattern (connect at least 4 dots) and tap the CONTINUE button.
Then re-draw your pattern and tap the CONFIRM button.
Note: Follow the on-screen instructions to create a backup PIN number in case you forget your pattern.
- PIN: Unlocks the screen with a number sequence. Enter a PIN (at least 4 digits) and tap the CONTINUE button. Re-enter your PIN and
tap the OK button to confirm it.
- Password: Unlocks the screen with an alphanumeric sequence. Enter a password (at least 4 characters) and tap the CONTINUE button.
