While setting a screen lock on LG Aristo 3 (Plus) & Aristo 4 plus, we get an option to add an extra layer of protection.
This is similar to a screen lock but is more secure. To enable this, we need to select the option”Require password to turn on the phone” during setting up a screen lock password.
Until you enter your secure startup PIN/Pattern/Password you won’t be able to get calls, messages, notifications, and alarms.
