Are you missing important calls because Xiaomi is making too quiet horns? The problem is familiar to many smartphone owners of this brand β even at maximum volume, the melody of an incoming call can barely be heard in a noisy environment, the reasons are rooted in the limitations of MIUI firmware, hardware features of speakers or incorrect audio profile settings.
In this article, weβll look at 7 proven ways to increase the volume of beeps on Xiaomi, from basic settings to hidden engineering menu features. Youβll learn how to bypass software constraints, optimize sound for different scenarios (outdoors, in transportation, at home), and even physically improve playback through the speaker. All methods have been tested on models from Redmi Note 10 to Xiaomi 14 and are compatible with the latest versions of MIUI 14/15.
Before you start settings, check the obvious: is the phone not on Do Not Disturb Mode (in the notification curtain) and is not set to a quiet tune manually. If that's not the problem, read on.
1. Volume settings in MIUI: What you're missing
Most users limit themselves to moving the volume slider on the sidebar, but MIUI has hidden parameters that directly affect the volume of the beeps. Let's start with them.
Go to Settings β Sound and vibration β Volume. Here you will see four sliders:
- π Call melody - the main loudspeaker regulator.
- π΅ Media β volume of music and video (does not affect calls!).
- π Alarm clock β a separate setting for alarm clock signals.
- π Notifications - sounds SMS, Push and other alerts.
Key point
The melody of the call
Then open Settings β Sound and vibration β Additional settings β Amplify sound. Here activate the option βRaise the volume speakerβ β this will increase the audio power by 10-15% due to a slight distortion (on some models the option is hidden and requires to be turned on through the engineering menu).
β οΈ Note: Xiaomi with stereo speakers (for example, POCO F5 Xiaomi 13T) The amplification of sound can cause an imbalance between the top and bottom speakers.
2. Engineering menu: hidden volume settings
If the standard settings don't work, you should go to the Engineering Mode, where you can manually increase the microphone volume, the speaker, and even adjust the frequency of the sound. Careful: the wrong changes can lead to distortion of the sound or overload the speaker.
To open the engineering menu:
- Open the Phone app and enter the combination: ##36446337###
- Select Hardware Testing β Audio β LoudSpeaker Mode.
- In the Max Vol section, set the value 160 (by default 140-150).
- Save the settings and restart the phone.
For models with Qualcomm Snapdragon (most Redmi and POCO) is available advanced mode:
- π In Audio. β Normal Mode β Type select Sph (Speaker).
- π Increase Level 0-Level 6 by 5-10 units (e.g., from 127 to 135).
- π Apply changes and check the sound with a test call.
What to do if the engineering menu does not open?
3. Third-party applications for sound amplification
If MIUI's software constraints don't allow you to turn up the volume, third-party utilities will come to the rescue, and they work on two principles:
- Direct amplification β increases the amplitude of the sound signal (risk of distortion).
- Equalizer β optimize frequencies for better audibility of horns.
Top.-3 tested applications:
- π Volume Booster GOODEV β It increases volume by 20 to 30 percent without root rights, supports separate settings for calls, alarms and media, minus: it can cause wheezing in dynamics at maximum values.
- ποΈ Equalizer FX β It allows you to adjust the equalizer specifically for the beeps. Recommended settings: lift the sliders by 200-500 Hz (these are the frequencies of the human voice that run the ringtone of calls).
- π οΈ SoundAssistant (from Samsung, but it works for Xiaomi) gives separate control over the volume of calls, alarms and notifications. + sound.
Before installing, check the permissions of applications. Avoid utilities that request access to SMS, contacts or geolocation - these are unnecessary permissions for adjusting the sound.

4. Physical ways to improve sound
If the software isn't working, the problem could be the hardware, whether it's a clogged speaker, a damaged membrane, or a weak amp.
| Problem. | Signs. | Decision |
|---|---|---|
| Clogged speaker | A muted, wheezing sound | Clean the speaker hole with a soft brush or compressed air (keyboard canister). |
| Membrane damaged. | Distortion at high volume, crackling | Replace the speaker (cost: 300-800) β½ Redmi often fails the bottom speaker. |
| Weak amplifier. | A quiet sound even at maximum, without distortion | Install an external Bluetooth speaker (such as the Xiaomi Mi Portable Bluetooth Speaker) and reconfigure the audio output to it. |
| Poor sealing of the hull | The sound is deaf, like from under the water. | Check the sealing gums after disassembling the phone (relevant for models with IP53 protection). |
For a temporary solution, you can use directional sound:
- π― Attach a small plastic resonator to the speaker (like a bottle cap with a hole) to amplify the sound waves in one direction.
- π¦ Put the phone in an empty box (a package from headphones will do) β this will create an acoustic amplifier effect.
β οΈ Warning: If after cleaning the speaker the sound has not improved, and when playing the test melody (Settings) β Sound. β Speaker test, distortion is a sign of hardware malfunction, further amplification of sound software can permanently disable the speaker.
5. Set up a sound profile and notifications
Sometimes the problem is not the volume, but the wrong sound profile, for example, if you select a Quiet or Meeting profile, the beeps will be muted even at maximum volume.
- Open the notification curtain and hold the icon π (sound-mode).
- Choose Sound or Loud (not Vibration or No Sound).
- Turn off the option "Silent Notifications" in Settings β Sound β Do not disturb.
Also check the settings of individual tunes for contacts:
- π Open Contacts, select the right contact β Edit β The melody of the call.
- π Make sure you choose a loud melody (such as "Ring Ring" or "Over the Horizon") rather than a quiet signal (such as "Silent" or "Vibration").
- π΅ For maximum audibility, download your own tune in format.mp3 High amplitude (can be created in Audacity with amplification) +6 dB).
π‘
To check the real volume of the beeps, call the phone from another device and measure the sound level using the Decibel X application. The norm for the street is 75-85 dB, for the room - 65-75 dB.
6. Update firmware and reset settings
Some versions of MIUI (especially 12.5-13) had bugs that limited the volume of the beeps. If your Xiaomi hasn't updated in a while, check the available updates:
- Go to Settings β About the phone β System update.
- If you have an update, install it. Importantly, back up your data before you update.
- After installation, reset the sound settings to factory: Settings β Sound β Resetting the sound settings.
If the update is not available or it didnβt help, do a partial reset:
- Open Settings β About the phone β Reset settings.
- Select "Reset Sound and Vibration Settings" (not a full reset!).
- After restarting, set the volume again.
For advanced users: if the problem has appeared after the update, you can roll back to the previous version of MIUI via Fastboot.

Before resetting or rolling back your firmware, check if the volume drop is related to a specific update. Read the feedback on forums (such as 4PDA or XDA-Developers) on your model.
7.Alternative solutions: vibration, light, smart watches
If you canβt raise the volume of the beeps, consider alternative ways to alert you about calls:
- π³ Vibration. + Light signal: activate in Settings β Sound. β Call vibration and light indicator (if any) on some models (Xiaomi) 12T, POCO F4) Color indications are supported for different contacts.
- β Smart watch or fitness bracelet: connect Mi Band or Xiaomi Watch β they vibrate and show incoming call even if the phone is silent.
- π¦ Camera flash: Enable the Settings option β Special facilities β The flash on the calls, even in the pocket.
- π’ Voice Assistant: Configure Google Assistant or Alice to voice the callerβs name (in the assistant settings) β Alerts).
For owners of Xiaomi with Always-On Display (such as Xiaomi 13 or Redmi K60), it is useful to activate the display of incoming call on the locked screen: Settings β Lock screen β Show notifications.
