How to set the lock screen for Lenovo a800 mobile phone

According to your description, I suggest you go to the system settings-security-lock screen of your mobile phone to make relevant settings. The system provides the following four screen locking and unlocking methods:

① Slide to unlock;

② Pattern Unlocking: You must draw a pattern to unlock the screen. Appears only after the unlock mode function is set. When canceling, you need to enter the last set unlock pattern;

③PIN unlocking: (enter the digital PIN unlocking screen)

④ Password Unlocking: Enter the password to unlock the screen.

Please understand and try the above.
