How to remove the sound of keys when dialing on Xiaomi: all ways

The audio signals used to dial on Xiaomi smartphones can be annoying in quiet rooms or during important calls.

In this article, we will discuss all the working ways to turn off the dial, from the obvious to the hidden. You will learn how to do this through system settings, engineering menus or third-party applications. And we will explain why after updating MIUI or resetting the sound can return and how to prevent it. The instructions are relevant for all Xiaomi models based on Android 10–14, including Redmi Note 12, POCO X5, Xiaomi 13T and others.

Can we turn the sound off forever? Yes, but with reservations:

Method 2: Use of an engineering menu (for power users)

If standard settings don’t work, you can turn off the dial sound via the Engineering Mode, a method that works even on Chinese firmware, but requires caution that improper actions can disrupt the network.

What to do if the sound is back after the MIUI update

• 📥 Create a backup of settings through Settings → Additionally. → Backup and reset.
• 🔧 Use it. ADB-command for permanent shutdown (see Method 3).

2. Check if permissions for third-party applications have been reset (Method 4).
3. If you use custom firmware (e.g. xiaomi.eu), upgrade to the latest version, which often fixes sound bugs.
