15. How to set up Smart Lock on LG K30
Before using Smart lock we need to set a secure lock as pin, pattern or password as a backup.
To do this go to Settings < Lock screen & security < Select screen lock and set pattern, PIN or passwords as your screen lock.
Now go one step back to “Lock screen & security” and tap “Secure lock settings”
Choose the last option i.e. Smart Lock. Enter your lock screen pin, password or pattern to proceed further
The 4 smart lock options are, on-body detection, trusted places, trusted devices, and voice match.
These locks are smart enough and you could use either of these to avoid the hassle of the screen unlocking.
