How to increase or decrease the volume of the speaker when calling Xiaomi: all ways

Have you noticed that the speaker is not hearing you well during calls on Xiaomi, or the voice in the handset itself sounds too quiet? The problem with setting the volume of the conversational speaker is one of the most common among owners of Redmi, POCO and Mi smartphones. Unlike media sound, which is regulated by volume buttons, the volume setting during a conversation is often hidden in the depths of the menu or requires additional manipulation.

In this article, we will analyze all available ways to change the volume of the speaker when calling - from standard settings. MIUI You'll learn how to fix a quiet sound in the handset, why the person may not hear you, and what to do if the volume control during a conversation does not work. 11/12/13 series, Redmi Note 10/11/12, POCO F/X/M and other devices based on MIUI 12–14.

Why the volume of a speaker can be too quiet or loud

Before you start setting up, it's important to understand the cause of the problem, and 80 percent of the time, low volume during a call is not due to a hardware malfunction, but to software limitations or failures.

• 🔊 Limitations MIUI: By default, Xiaomi’s firmware blocks the maximum volume of the speaker to protect the user’s hearing, and the microphone can be artificially underreported.
• 📱 Contamination of the speaker or microphone: Dust, moisture or mechanical damage to the speaker's grid leads to muffled sound, often when you put the phone down on the table with the screen, the sound becomes even quieter.
• 🔄 Failures after update: Updates MIUI sometimes reset individual audio settings or make changes to voice processing algorithms (e.g., noise cancellation).
• 🛠️ Incorrect sound uniformity settings: Some Xiaomi models have hidden balance options between the top and bottom speakers that affect the volume during a conversation.

If the problem comes on suddenly, try restarting your phone first, which often helps with temporary crashes. If the quiet sound is only seen in certain conditions (such as when using a headset or in a noisy room), the causes may be specific.

⚠️ Warning: If the speaker drops to zero after falling off the phone or getting moisture, don't try to adjust it programmatically. This may indicate a break in contacts or damage to the speaker membrane - repairs are required.

Method 1: Standard volume setting during a call

The most obvious, but often ignored, way is to adjust the volume directly during a conversation, and unlike media sound, which changes volume buttons on the sidebar, the volume of the speaker is tuned differently:

1. Make or take the call.
2. On the call screen, click the volume button (usually located to the right or left of the call completion button).
3. A slider will appear with the inscription “Loudness of conversation” – move it to the desired position.

If the slider is missing or does not respond to pressures, this may mean:

• 🔇 On your Xiaomi model, the volume control option during the call is disabled (found on some firmware for the phone). POCO).
• 📵 Calling is done via VoLTE or VoWiFi, where volume settings may vary.
• 🔄 The phone activated Do Not Disturb or In your pocket, which limits sound.

💡

If the volume button doesn’t appear on the call screen, try pressing the physical volume up/down button on the phone’s body – sometimes this will activate the slider.

Method 2: Configure through “Special Opportunities”

The MIUI special features menu contains additional audio settings that can affect the volume of the speaker, which is especially useful if the standard controller does not give a sufficient volume level:

1. Open the Settings. → Special facilities.
2. Go to the section "Hearing" (or Audio depending on the version of MIUI).
3. Activate the option of Sound Amplification or Volume Monitor (if available).
4. In some firmware here there is a slider Loudness of conversation - move it to the maximum.

This section may also include:

• 🔊 Amplifying the sound in headphones – useful if you use a headset.
• 🎧 Monoaudio – combines sound from both speakers into one, which can increase volume.
• 📞 Volume Notifications – The phone will alert you if the sound level exceeds a safe threshold.

⚠️ Warning: Sound amplification can distort the voice of the interlocutor at maximum values. If after activation there are wheezing or echoes, reduce the gain to a comfortable level.

Method 3: Engineering menu (for power users)

If standard methods don't work, you can use the Engineering Mode, which hides low-level audio settings, which requires caution, as incorrect changes can lead to failures.

To open the engineering menu:

1. Open the Phone app.
2. Enter the combination: ##36446337##
3. You will be taken to the EngineerMode menu (on some models Xiaomi may be called CIT or MTK Engineer Mode).

Next:

1. Go to the Hardware Testing → Audio section.
2. Select LoudSpeaker Mode (for speaker) or Normal Mode (for conversational speaker).
3. In the Value field, set the maximum value (usually 160 or 255).
4. Press Set, then restart the phone.

To set up the microphone:

• In the same menu, select Mic or Microphone.
• Set the Level value to 5 or 6 (maximum).
• Check the sensitivity of the microphone by calling another phone.

⚠️ Attention: Changes in the engineering menu are not reset after resetting the phone settings. If after editing the parameters there are problems with sound (for example, constant noise in the dynamics), contact the service center - it will be difficult to return factory values yourself.

Method 4: Resetting the sound and network settings

If the volume problem is caused by a MIUI update or a new app, resetting the audio and network settings will help, a method that doesn't affect personal data, but returns all the settings related to sound and communication to factory settings.

How to perform the reset:

1. Open the Settings. → The phone.
2. Click on the MIUI version several times until you become a developer! (unless the developer mode is activated).
3. Return to the main settings menu and open Additional → Reset settings.
4. Select Network and Sound Reset (or Communication Settings Reset).
5. Confirm the action and wait for the phone to restart.

After discharge:

• 🔄 Check the volume of the speaker - it should return factory values.
• 📱 If necessary, reconfigure APN for mobile Internet (options can be requested from the operator).
• 🔊 Re-activate options in Special Options if they were previously enabled.

Method 5: Third-party applications for sound amplification

If the built-in methods don't work, you can use third-party applications, and they work on two principles:

1. Amplifies sound at the software level (e.g., Volume Booster or Sound Amplifier).
2. Equalizer correction to improve voice legibility (e.g., Equalizer FX).

Top.-3 apps:

• 📲 Volume Booster GOODEV — It increases the volume of the speaker to 20 to 30 percent without distortion. MIUI 12–14.

How to use the Volume Booster GOODEV:

1. Download and install the app from Google Play.
2. Launch it and give access to the sound settings.
3. Select Call Volume (volume of call).
4. Move the slider 100-120% (do not exceed 130% to avoid distortion).
5. Save the settings and check the volume during the call.

⚠️ Attention: Sound amplification apps can drain the battery faster and cause the processor to overheat during long conversations.

💡

Third-party applications don't replace repairs for hardware malfunctions, and if the speaker is physically damaged, no software will return the factory volume.

What to do if nothing helps: Diagnostics of hardware problems

If all software methods have been tried, but the volume of the speaker is low, it's probably a hardware malfunction.

Dynamics test:

• 🔊 Turn on speakerphone while calling – if the sound becomes normal, the problem is in the upper (conversational) speaker.
• 🎵 Play music through the built-in speaker – if the sound is quiet and in media files, the bottom (multimedia) speaker is faulty.
• 📱 Light a flashlight into the speaker grille - if dust or moisture is visible, cleaning is required.

Microphone check:

• 🎤 Record the voice memo with a standard voice recorder, and if it's quiet or noisy, the microphone is faulty.
• 📵 Call another phone and check how you're heard. If someone complains about a quiet voice, the microphone is a problem.

Typical hardware faults and their signs:

If you have confirmed a hardware malfunction, contact the Xiaomi service center.

• 🔧 Replacement of the Speaker: 800–1500 ₽ (model-wise).
• 🎤 Microphone replacement: 600–1200 ₽.
• 🔌 Repair of the plume: 1000–2000 ₽.
