LG LGVK810 - Manual (Page 25)

23 The Basics
PIN: A number sequence unlocks the screen. Enter a PIN (at least 4 digits),
then tap Continue. Enter your PIN again, then tap OK to confirm it.
Password: An alphanumeric sequence unlocks the screen. Enter a
password (at least 4 characters), then tap Continue. Enter your password
again, then tap OK to confirm it.
From then on, any time you want to unlock the screen, you will need to
perform the unlock action you set (swipe, face recognition, pattern, PIN, or
password) to gain access to it.
CAUTION Create a Google Account before setting a screen lock and remember the Backup PIN
you created so you minimize the risk of needing to perform a hard reset which will
delete your personal data.
When you can’t recall your Pattern, PIN, or Password
If you can’t remember your unlock sequence, tap Forgot pattern? at the
bottom of the screen, then you can unlock the tablet using your Google
Account (if you activated it on the tablet) or your Backup PIN that you
created when you set up the screen lock sequence.
 Enter your Google Account username and password, then tap Sign in.
 Enter your Backup PIN, then tap OK.
Unlock sequence attempts
You have 10 attempts to successfully enter your unlock sequence.
 After 5 attempts, you are prompted to manually enter text to verify that
you are trying to unlock the screen (it's not just random movements
touching the screen).
 After 10 attempts, the tablet will automatically perform a hard reset and
erase all of the user data stored on the tablet.
NOTE A warning message is displayed after the 9th attempt.
If you didn’t activate a Google Account on the tablet and you forgot your
Backup PIN, you have to perform a hard reset.
CAUTION If you perform a hard reset, all user applications and user data will be deleted from
your tablet's memory.
