The sound of locking the screen on Xiaomi: how to change, disable or return the standard

The screen lock sound on Xiaomi smartphones is one of those little things that either pleases the owner every time or starts to annoy after a week of use. Standard system tunes in MIUI often seem too loud, monotonous or just don't fit your style. Fortunately, the manufacturer has provided several ways to change them - from simple replacement through settings to install custom sounds through the file manager.

In this article, we will discuss all the current methods: how to change the lock sound to your melody, turn it off completely (including vibration), and return the factory settings if the experiments went wrong. Instructions will be suitable for all modern models, from the Redmi Note 12 to the flagship Xiaomi 14 Ultra, running on MIUI 12, 13 or 14. We will also touch on the nuances for devices with HyperOS, a new shell that gradually replaces MIUI.

Before you make any changes, consider that some system sounds (such as a fingerprint unlock signal) may be tightly tied to firmware, which will require additional manipulations, as we will discuss below.

Why it may not be possible to change the sound of the lock

On forums, users often complain that the audio settings do not have the option to change the lock melody.

• 🔄 Version. MIUI/HyperOS: In old firmware (up to) MIUI 10) The function was hidden or worked differently on newer versions (e.g, MIUI 14) The path to settings could have changed.
• 📱 Smartphone model: On some devices (for example, POCO F5 or Redmi 10C) manufacturer limits the customization of sounds.
• 🔒 Security Policy: On corporate or work phones, administrators can block changes to system sounds via Android Enterprise.
• 🛠️ Castom firmware: If you use informal firmware (like LineageOS), standard methods may not work.

If your lock sound doesn't change through the standard settings, don't be too upset. In the custom setup section, we'll talk about workarounds, including using a root file manager.

⚠️ Note: Some models (e.g. Xiaomi) 13T Pro) The lock sound is linked to the notification sound. If you change one, you automatically change the second one.
