How to increase the volume of a call on a Xiaomi phone: from standard settings to hidden features

Do you miss important calls because of a quiet signal on Xiaomi? The problem is familiar to many owners of smartphones of this brand - even at maximum volume, the melody can barely be heard in a noisy environment, the reasons lie in hardware constraints (weak speaker, dust in connectors) and in the software settings that the manufacturer hides from the user.

In this article, we will discuss 7 working ways to increase the volume of a call, from basic settings to advanced methods using engineering menus and third-party utilities. All instructions are relevant for the Redmi Note 12/13, POCO X5/F5, Mi 11/12 and other devices on MIUI 14/15.

1. Checking basic volume settings

Before you resort to radical measures, make sure that the problem is not in the basic settings. On Xiaomi, the volume of the call is adjusted separately from the media and alarm clock, many users confuse these parameters.

Open the Quick Settings Panel (swipe down from the top edge of the screen) and find the Volume slider. Click on the gear icon next to it, and a menu with separate regulators will open for:

• 🔔 The call is the main parameter that needs to be increased;
• 🎵 Media – volume of music and video (does not affect calls!);
• ⏰ Alarm clock – separate setting for wake signal;
• 📳 Notifications - sounds SMS, messengers and system alerts.

If the slider is already at its maximum, but the sound remains quiet, move to the next section. On some Xiaomi models (for example, Redmi 9A or POCO M3), the volume of the call is artificially limited at the firmware level, this is done to comply with European noise standards.

2. Change the ringtone to a louder one

Standard MIUI tunes are often optimized for "nice" sound rather than maximum audibility, and replace them with loud, high-frequency notes, which are better at cutting through noise.

How to do this:

1. Go to Settings → Sound and vibration → Call melody.
2. Select Local (if any) – this is where the system signals are stored.
3. Listen to the options with the names Ring_Synth_01, Ring_Classic_02 or Ring_Alarm_03 — They're usually louder than the rest.
4. If you don’t have a suitable one, upload your own tune (.mp3 or.m4a format) to the Ringtones folder on your internal drive.

💡

Use online services like Ringtone Cutter to cut the track for up to 30 seconds and turn up the volume by 10 to 15 dB before downloading.

For maximum effect, choose tunes with:

• 🔊 Sharp attacks of sound (e.g. classic phone calls);
• 🎚️ Minimal background noise (avoid bass tracks);
• 🔄 Repeated pattern: the brain recognizes a familiar sequence faster.

3. Activation of the "Sound Amplifier" mode in MIUI

There's a special mode hidden in MIUI firmware that increases the volume of the speaker by changing the frequency response, called the Sound Amplifier, and it's activated through special settings.

Instructions:

1. Open Settings → Special features → Sound amplifier.
2. Activate the switch at the top of the screen.
3. In the "Amplifier Settings" section, select:

"Accretion level"

This is a system-level approach that doesn't require root rights, but keep in mind that when you get the most power, you can have wheezing in the dynamics, which is normal for single-speaker budget models.

4.Use of the Engineering Menu (for Advanced)

If standard methods don't work, you can manually turn up the volume through the Engineering Mode, which requires caution - incorrect settings can damage the speaker!

Steps to enter:

1. Open the Phone app and enter the code ##4636## (some models may require #36446337###).
2. Select "Hardware Testing» → «Audio».
3. In the LoudSpeaker Mode section, find the following options:

Ring Volume

«Set»

💡

Changes to the engineering menu are reset once the firmware update is in place, and you'll have to repeat the procedure after the update.

⚠️ Attention: Do not increase the value above 160 — This can cause the speaker to overload and physically damage it. 12 Pro, POCO F4 GT) Change the settings for both (Speaker) Left/Right).

5. Third-party applications for sound amplification

If system methods fail, use specialized utilities that run on top of MIUIs and can increase volume by 20 to 30 percent through software-based sound processing.

To install ViPER4Android on Xiaomi without root:

1. Download APK with XDA Developers.
2. Install the ViPER4Android FX app and driver.
3. In MIUI settings, allow installation from unknown sources.
4. Include the sound handler in Settings → Sound → Sound effects.

How to diagnose:

1. Blow the speaker with compressed air (such as a can of cleaning equipment). Do not use wet wipes!
2. Check the sound on the headphones – if they ring loud, the problem is in the dynamics.
3. Record the sound from the microphone while playing the melody. If the recording is silent, the speaker is defective.
4. Compare it to another phone – run the same tune on two devices.

If the speaker is damaged, it will cost 800-2000 rubles to replace it in the service center (depending on the model). On Xiaomi with IP53 (dust protection), the problem is most often solved by cleaning the speaker grid.

7. Alternative solutions: vibration, LED, notifications

If you can’t increase the volume of the call, compensate for this with other ways of notifying:

• 🔄 Vibration with a unique rhythm:
• 💡 LED flash:
• 📱 Repeated notifications:

In the models with AMOLED-In the case of a screen (e.g. Xiaomi 13) you can turn on Always-On Display with incoming call display. AOD Notify.

For owners. POCO or redmi with IR-The blaster is a non-standard life hack: connect a smart lamp (for example, Yeelight) and set it to blink when an incoming call is made through the Mi Home app. This is important for those who often leave their phone in another room.
