2. In the security and privacy interface, we can click "Lock Screen and Password" to see "Lock Screen Style" and "Lock Screen Signature";
3. Of course, it needs to be set separately. Let's take the lock screen style as an example. After clicking enter, we can see all the styles in the current mobile phone. These styles are generated by the previously set theme. Only after changing the new theme will there be a new style, otherwise only the previous theme style will be displayed;
