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.

You can see I’m stuck at the Secure start-up screen on my Aristo 3 (Plus) and Aristo 4.

We get 30 attempts to unlock the screen.

To bypass the Google lock on Aristo 3/4 we need another phone to set up a SIM card lock. 

I’m using my LG Aristo 2 to lock a SIM Card.

If using an LG android phone –

Go to Settings > General > Lock Screen & Security > Set up SIM card lock as shown above.

Toggle on the “Lock SIM card” option.

A confirmation message flashes on the screen “SIM card lock enabled”.

Now, remove the SIM from LG Aristo 2 and insert it in your LG Aristo 3/4.
