How to delete a SMS taskbar in the mobile phone unlocking interface?

Press and hold the middle of the unlocking lever and pull down.

When sliding to unlock, there are three touch buttons, the first one is phone, with a blank in the middle, and the third one is SMS. As long as you click the SMS button and slide down, you will enter the SMS interface. If you click the phone button and slide down, you will enter the phone interface. If you click on the middle slide, you will enter the normal interface, which is the last page when you close the screen.
