How to get rid of lock screen in Samsung Galaxy S2?

Question

Lately, instead of just being shut down my Samsung Galaxy S2 shows this screen (see screenshot).

How can I get rid of it? I don't want to see this screen ever again. Somehow it appears only while I'm driving my car

Update(10/8/2015):

This screen appears ONLY whike I'm driving my car and the phone is connected to charger

Answer 1

You mean you want to just disable the lock screen completely? Here's how to do it:

1. Open your settings.
2. Go to Security and open your lock screen settings.
3. If you have a code or password set for your current lock screen, enter that code and continue.
4. Choose none as your lock screen option.
5. Lock your phone and unlock it again, it should open up your phone straight away and not show a lock screen.
