Are you tired of constantly asking your interlocutor to speak louder or call back because of a quiet sound in the Xiaomi speaker? The problem of low volume during calls is one of the most common complaints of users of Redmi, POCO and Mi smartphones. Even on flagship models like Xiaomi 13 Ultra or Redmi Note 12 Pro+ factory settings often limit the maximum sound level, leaving it insufficient for noisy streets or transport.
In this article, weโll look at 7 working ways to turn up speaker volume when talking, from standard Android settings to hidden menu options and third-party utilities. Importantly, some methods require root rights or accuracy to avoid damaging the hardware. Weโve flagged all the risky steps with warnings โ read carefully!
First, determine whether the problem is whether the silent sound is only in the ear (top) or also in the speakerphone? If the problem is only with the top speaker, the fault may be a clogged grid, a damaged plume or a software limitation. For diagnostics, try calling on headphones โ if the sound is clear, it's the hardware of the smartphone.
1. Check the basic volume settings
Before you dig deeper, make sure that the problem is not the basic settings. On Xiaomi (especially on MIUI 14 and later), the volume of calls is regulated separately from media and notifications.
- ๐ When you call, press the volume buttons, and you'll see a slider called Volume of Call. Make sure it's at its maximum.
- ๐ฑ In Settings: Go to Settings โ Sound and vibration โ Volume and check the level for Call.
- ๐ Do Not Disturb: If it's on, it can jam calls. Open the notification curtain and turn it off.
Some models (such as the POCO X5 Pro or Redmi K60) have a separate audio amplification setting in the Special Features section, activate it if available:
- Open Settings โ Special Opportunities โ Hearing.
- Find the option to amplify sound and turn it on.
- Set the Max slider to the right level.
โ ๏ธ Warning: If the sound is still quiet after this manipulation, do not turn up the volume through the engineering menu immediately - first check the speaker for physical damage.
2. Use the Engineering Menu (MTK/Qualcomm)
The engineering menu is a hidden settings section where you can manually increase the microphone volume and speaker.The method works on most Xiaomi, but the menu interface differs depending on the processor: MediaTek (MTK) or Qualcomm Snapdragon.
For MediaTek (models like Redmi 9A, POCO M3):
- Open the Phone app and type the combination: ##36446337## (or #3644633## on some firmware).
- Go to Hardware Testing โ Audio โ Normal Mode.
- Find Speaker and Receiver (top speaker for conversations).
- Increase Max Vol by 5-10 units from the current one, and do not exceed 160 for Receiver and 180 for Speaker, which can cause distortions.
For Qualcomm (e.g. Xiaomi 12T, Redmi K50):
- Enter the code on your phone: ##4636##.
- Select Information โ Audio.
- In the Volume section, find the lines Voice Call and Ring.
- Increase the values by 1-2 levels (for example, from 5 to 7).
| Processor | Engineering menu code | Max: Safe value for Receiver | Max: Safe value for Speaker |
|---|---|---|---|
| MediaTek (MTK) | ##36446337## | 160 | 180 |
| Qualcomm Snapdragon | ##4636## | 7 (level) | 9 (level) |
| Dimensity (new MTK) | ##86583## | 150 | 170 |
โ ๏ธ Attention: Incorrect settings in the engineering menu can damage the speaker or microphone. If there are wheezing or distortions after the changes, return the values to the standard and contact the service.
Write down the current volume values
Do not exceed the recommended maximums
Reboot your phone after the changes
Check the sound on different types of calls (normal, loud communication)-->
3. Install applications to amplify sound
If the engineering menu seems complicated, use third-party utilities. They are safer, but require permission to change system settings.
- ๐ Volume Booster: a simple booster with pre-profiles for calls. MIUI rootless.
- ๐ง Precise Volume: allows you to adjust the volume more accurately for each type of sound, including calls.
- ๐ ๏ธ SoundAssistant (from Samsung, but running on Xiaomi): gives access to hidden audio settings, including separate speaker control.
How to install and configure Volume Booster:
- Download the app from Google Play.
- Open it and give access to the sound settings.
- Select the Call Volume tab.
- Move the slider 120-140 percent (no higher, otherwise there will be distortions).
- Activate the Apply on Boot option to save the settings after the reboot.
For models with MIUI 13/14, you may need to disable battery optimization for the application:
- Go to Settings โ Applications โ Application Management.
- Find Volume Booster and select Battery Limitation โ No Limits.
๐ก
If the sound is intermittent after installing the booster, reduce the gain to 110% and restart the phone.
4. Clean the speaker of dust and debris
Often the reason for quiet sound is mechanical. Xiaomi speaker (especially the top one, for conversation) is easily clogged with dust, villi or toast deposits. This reduces the volume by 30-50%.
- ๐งน Soft brush: use a soft bristling toothbrush or makeup brush. Carefully run the speaker in circular motions.
- ๐จ Compressed air canister: direct the jet at an angle of 45ยฐ to the grid at a distance of 5-7 cm Do not blow too close - you can damage the membrane.
- ๐งฒ Scotch or sticky tape: Cut a piece and press gently against the net, then remove - this will remove the adhesive dust.
For deep cleaning (if the sound has become hoarse):
- Remove the speaker's protective mesh with a thin needle or tweezers (it is glued on some models).
- Wipe the speaker membrane with a cotton swab dipped in isopropyl alcohol (no more than 70% concentration!).
- Let dry for 10-15 minutes before assembly.
โ ๏ธ Warning: Do not use sharp objects to clean - even a slight pressure on the membrane of the speaker can break it. If after cleaning the sound does not improve, the problem may be in the plume or contacts (requires disassembly of the phone).

5. Update the firmware or roll back to the old version
Sometimes the quiet sound during calls is a firmware bug. For example, MIUI 12.5 for the Redmi Note 10 Pro had a famous volume-limited glitch after the upgrade.
- Open Settings โ About the phone โ System update.
- If you have a new version, install it. Often, patch notes fix audio bugs.
- If the problem has occurred after the last update, try to roll back to the previous version via Fastboot.
How to roll back to the old firmware (requires an unlocked bootloader):
- Download the desired version of MIUI from the official Xiaomi website (Archive section).
- Unpack. ZIP-Firmware file in a folder with fastboot utilities.
- Connect your phone to your PC in Fastboot mode (press Power + Vol- when you turn on).
- Run the command: fastboot flash all name file firmware.zip
| Xiaomi model | The Problem Version of MIUI | Corrected in version |
|---|---|---|
| Redmi Note 10 Pro | 12.5.3.0 | 12.5.4.0 |
| POCO X3 NFC | 12.0.8.0 | 12.0.9.0 |
| Mi 11 Lite | 12.5.2.0 | 12.5.5.0 |
๐ก
Before rolling back the firmware, back up your data via Settings โ Additional โ Backup. Reset will reset the phone to factory settings!
6. check the operator's settings and SIM-map
Rarely, it happens that the problem is not the phone, but the settings of the mobile network. Some operators (for example, Tele2 or Yota) limit the volume of VoLTE calls at the protocol level.
- ๐ถ Turn off VoLTE: Go to Settings โ SIM-maps and mobile networks โ [Yours. SIM] โ Use VoLTE and deactivate the option.
- ๐ Reset your network settings: in Settings โ System system โ Resetting settings โ Resetting Wi-Fi, Mobile Network and Bluetooth.
- ๐ฑ Check the other one. SIM-card: insert the card of another operator and call โ if the sound has become louder, the problem is in the settings of your tariff.
If you use a virtual operator (like Tinkoff Mobile or SberMobile), contact support and check if there are restrictions on audio codecs. Some virtual SIMs work through proxy servers that compress voice traffic.
7. Hardware malfunctions: when to contact the service
If none of these things worked, it's probably hardware, and here are the signs that you need to take your phone to the service center.
- ๐ The sound disappeared completely or became very quiet even in headphones.
- ๐ The speaker makes wheezing, crackling or "bubbling" sounds.
- ๐ The problem only appears when the phone is tilted (the plume may have moved away).
- ๐ง The phone fell into the water or was subjected to a strong vibration.
The average cost of repair speaker on Xiaomi:
| Type of repair | Price (โฝ) | Date(days) |
|---|---|---|
| Cleaning the dynamics | 500โ1 200 | 1 |
| Replacement of the top speaker | 1 500โ3 000 | 1โ2 |
| Repair of audio plume | 2 000โ4 500 | 2โ3 |
If the phone is warranty, do not disassemble it yourself - this will void warranty obligations.
