How to make Xiaomi phone ring: the complete guide

When a Xiaomi smartphone stops sounding when a call is made, it can be taken by surprise at the most inopportune moment. Users often find the device silent even though the screen lights up, or the call only goes away with the headphones connected. This is a common problem that is solved 90% of the time by the software settings of the MIUI or HyperOS operating system, rather than requiring complex repairs.

The reasons for the lack of sound can range from the corny volume slider turned off to the activation of hidden spam filtering functions. Android, which runs the phones of this brand, has a complex hierarchy of sound profiles, and a failure in one of them can lead to complete silence. In this guide, we will discuss in detail all possible causes and ways to eliminate them.

It is important to understand that audio drivers in Xiaomi smartphones work in conjunction with the system permissions of applications. If the phone or Contacts lost the necessary rights, the audio signal will simply not be triggered by the system. Below we will consider a step-by-step algorithm of actions to restore the speaker.

Checking the main volume profiles

The first thing to do when you find a problem is to check the current sound profile. In the MIUI shell, there is a division into the volume of media, alarm, call and notifications. Often users turn down the overall volume with buttons on the case, believing that they are adjusting the call, but actually changing the sound level of videos or games.

To fine tune it, you press the volume button and when the slider appears on the screen, press the three-dot button or the gear next to it. An extended menu will open where you will see individual scales. Make sure that the Ringer slider is raised to an acceptable level, and that's the one responsible for incoming calls over the cellular network.

⚠️ Warning: If the call slider is active but no sound, check if the system has a "No Sound" or "Vibration" mode. The notification curtain (swipe down from the top edge) should have a speaker icon on, not a crossed-out speaker or vibrator.

You also need to look at the Pocket Mode feature, which in some versions of the firmware can conflict with the proximity sensor, which causes the phone to "think" that it's in your pocket and block the sound of the call so that it doesn't ring into the void, and you can turn it off in the audio settings if standard methods don't work.

Do Not Disturb and Sleep Schedule

One of the most common reasons why Xiaomi is silent when calling is the activated Do Not Disturb mode. Unlike the usual silent mode, this feature completely blocks sound and light notifications, as well as vibration, so as not to disturb the user during sleep or meetings.

You can check the status of this mode through the notification curtain or in the Settings → Sound and vibration → Do not disturb. Special attention should be paid to the item “Schedule”. Often users accidentally activate the automatic mode for the night, but forget to turn it off in the morning, or the time interval is knocked down due to the clock transfer.

Inside the Do Not Disturb settings, there is an important Exception option: Even if the mode is active, you can allow calls from selected contacts or re-calls (if the same subscriber calls a second time within 15 minutes), a critical setting for emergencies.

💡

Use the voice command “OK Google, turn off the mode do not disturb” if you are afraid to miss an important call and do not want to climb into the settings menu.

It’s also worth checking whether Sleep or Work is activated in the digital balance, which can limit not only the use of apps, but also the audio of events, creating the illusion of a speaker malfunction.

Blocking Unknown Numbers and Filtering Spam

Xiaomi’s current smartphones are equipped with powerful built-in anti-spam tools that are based on Tencent’s database or local listings. If your phone is silent when calling from unfamiliar numbers but rings perfectly to contacts from the phone book, the problem lies here.

To check your settings, go to the Security app (green lightning icon), then select Antispam → Blacklist. Here you can activate the Block Calls from Unknown Numbers function, in which case the call simply resets or passes without sound, and the call log may not even get into the call log.

• 📞 Open the phone application (pipe).
• 🛠 Click on three dots in the corner and select Settings».
• 🚫 Go to the “Block” or “Antispam” section».
• 🔍 Check if the boxes are on the block of hidden numbers.

In addition, carriers offer Anti-Determinator services that may conflict with Xiaomi’s determinant. If you use such services, try disabling them on the carrier side or in the Security app, add your numbers to the whitelist of exceptions.

Sound settings in the "Phone" application

In the MIUI shell, the call app has its own audio settings that can override the system, sometimes after the system update or the application itself, the settings are confused, and the ringtone is replaced with "No Sound" or a file that is corrupted.

Go to Settings → Sound and Vibration → Call Melody. Make sure you choose a standard melody, not an empty file. Also check if you have a unique melody set for a specific contact that you can't get through. Individual contact settings take precedence over general ones.

The important thing is that the volume is going up. If this is enabled, the phone starts ringing very quietly, and the volume goes up gradually. In a noisy place, you can just not hear the first seconds of the call, deciding that the phone is silent. You can turn this option off in the advanced audio settings.

If you use third-party calls (like from Google or Truecaller), make sure they have all the necessary permissions to handle sound and are the default app for making calls.

Comparison of MIUI and HyperOS sound profiles

With the release of the new HyperOS operating system, the audio menu structure has changed, and users who have moved from older versions of MIUI may find it difficult to find the usual switches. Below is a table that helps to navigate interface differences.

The main difference is that the new system is more deeply integrated with the smart home ecosystem. If you have Xiaomi Home devices connected, the phone can automatically go into silent mode when you come home, as long as it is configured in automation scenarios.

💡

The audio settings interface has become more logical in HyperOS, but adding new layers of automation requires careful verification of smart home scenarios.

Hardware problems and resetting settings

If software methods have failed, it's worth considering a hardware malfunction. The speaker can get clogged with dust, especially if the phone is more than two years old and has been used extensively in dusty environments. A gentle brushing can restore sound.

It's also possible to program the audio driver to crash, and it helps to reset all the settings to the factory, but before that, make sure to back up the data. If even after a full reset (Wipe Data), the phone does not make sounds when you call, it's a physical break in the speaker or the plume.

⚠️ Warning: Before going to the service center, try connecting a Bluetooth headset, and if there is sound through it, then the problem is with the built-in speaker, not the motherboard.

In rare cases, the problem lies in a poor quality protective film or case that covers the hole of the speaker or main speaker.

You can use an engineering menu for deep diagnostics. Type ##6484## in your phone app. In the CIT menu that opens, select the Receiver test and Speaker test, which isolates the problem: if you have sound in the test and you don't call, it's the software problem, if you don't have it anywhere, it's the hardware.

##6484##

This code works on most Xiaomi and Redmi devices, and it allows you to check not only the sound, but also the vibrator, microphone and other sensors, which will help you pinpoint the culprit behind the silence of your device.
