0 1 Take Xiaomi mobile phone as an example (other mobile phones are similar). First, enter the settings of the mobile phone, drop down and find "lock screen, password, fingerprint", and click in.
You can change the lock screen style in the "Lock Screen Password" column, and then drop down to find the "Lock Screen Advanced Settings" to set the lock screen signature.
In the first column, how long can I start the screen lock signature after setting the screen lock? Click "Lock Screen Signature" to modify the signature.
Click the button above first, and then enter it in the input box below. Be careful not to use too many words. Click the tick in the upper right corner when you are finished.
