If you do not see this option

• No widgets to add? In the Classic layout on our phone, only the date and time (clock style and font) and the signature can be changed. There is no widget picker.
• Can't change the wallpaper here? Our lock screen showed a different picture with a news headline each time. That is a wallpaper slideshow, and the editor says Can't edit wallpapers when using wallpaper slideshow.
• Phone still on MIUI 14? Xiaomi's steps for MIUI 14 go through Settings, Lock screen, Lock screen clock format, where you choose a clock layout. Source: How to set the Lock screen clock format on a MIUI 14 phone?

If this does not work

• Editor does not open? Press and hold for longer on an empty area, not on a notification or the camera icon.
• Clock style won't change? Xiaomi says the layout cannot be changed with a third-party theme, and on MIUI 14 the format cannot be changed while Dual clock is on. Source: How to set the Lock screen clock format on a MIUI 14 phone?
• Changes gone? They are kept only after you tap Apply. Cancel and Exit leave the lock screen as it was.

About this guide

HyperOS 3 has its own lock screen editor. On our phone it changes the clock and a line of text, the signature; it does not add widgets in the Classic layout, and it cannot change a wallpaper slideshow.

The screenshots are from our Redmi Note 15 Pro 5G with Xiaomi HyperOS 3.0.308.0 and Android 16, in Light mode. We opened every screen and changed nothing: we tapped Cancel and Exit each time.

Good to know

Notifications missing on the lock screen? Xiaomi lock screen notifications not showing?.

In short: Hold the lock screen, Customise, tap the time for Clock and Font, signature below, Apply.
