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

Are you missing important calls because of the quiet sound on Xiaomi?The problem is familiar to many smartphone owners of the brand - even at maximum volume, the melody can barely be heard in noisy environments. The reasons are both hardware limitations (weak speakers in budget models) and MIUI software settings, which by default lower volume to save energy.

In this article, we will discuss 7 working methods, from basic settings to hidden engineering menu features and third-party utilities, you will learn how to increase the volume of calls on Redmi Note 12, POCO X5, Mi 11 and other models, including solutions for cases where standard methods do not help.

1. Basic volume settings in MIUI

Start by checking the obvious -- maybe it's solved with a few touches of the screen. In MIUI 14 and later, the sound control algorithm has changed, so even if you've previously set the volume, the settings could reset after the upgrade.

Open Settings → Sound and vibration. Here you are interested in three key points:

• 🔊 Volume is a call slider (not to be confused with media volume!) Move it to the right all the way to the end.
• 🔔 Notification sounds – turn on the option to “Revenge the volume in your pocket” (available on models with the IR-sensor).
• 🎵 The ringing melody – some standard tunes (MIUI Ring, Bamboo) quieter than the third-party. Try Reflection or Horizon -- they have a wider dynamic range.

If you're still quiet after this manipulation, move on to the next section. Importantly, on some models (e.g. Redmi 10A), the maximum volume of the call is limited at the firmware level, which is an intervention to protect the speaker from overload, in which case only manual intervention through the engineering menu will help.

2.Separate volume setting for calls and notifications

V MIUI The volume of calls and notifications is synchronized by default, but it can be split. This is useful if you want to have an alarm or a different alarm. SMS-The alerts sounded louder than the incoming calls.

Instructions:

1. Go to Settings → Special features → Improve the sound.
2. Activate the option “Separate the volume of notifications and calls”.
3. Return to Settings → Sound and vibration – now you will have separate sliders for each type of sound.

Is the "Separate Volume" mode activated in special features?

Is the maximum volume set for calls separately?

Have you checked the settings for the alarm clock (Settings → Alarm → Volume)?

Reboot your smartphone after the changes?-->

Note for POCO: On some devices in this lineup (e.g., the POCO X3 Pro), the option is hidden. To see it, pre-disable MIUI Optimization in Settings → About Phone → MIUI version (tap 7 times on version number).

3. Engineering menu: hidden volume settings

If standard methods don't work, it's time to go to the engineering menu (#4636## or #3644633##) where you can manually increase the volume of the call to values that are not available in the normal interface.

Step-by-step:

1. Open the Phone app and type ##4636##.
2. Go to the Hardware Testing → Audio tab.
3. In the Ring section, set Max Vol to 150 or 160 (standard 100).
4. Press Set and restart the device.

Warning: Setting a value above 160 can cause clipping (sound distortion) and shorten the life of the speaker. The optimal range is 120-150.

⚠️ Note: On devices with stereo speakers (such as the Xiaomi 13 Pro), changing the settings in the engineering menu can cause a sound imbalance between the top and bottom speakers. Before setting up, check which speaker is responsible for the calls (usually the bottom one).

4. Third-party applications for sound amplification

If the software methods don't work, look at the apps from Google Play, which work on two principles: either modify the system's sound profiles or use its own sound engine.

For most users, SoundAssistant is optimal — it doesn't require root rights and allows you to flexibly adjust the volume for each type of notification. Install it from Google Play, then:

1. Open the application and provide all the permissions requested.
2. Go to Volume and activate Separate App Volumes.
3. For calls, set the volume to 130-140% of the standard.

💡

If the sound becomes intermittent after installing the application, turn off the option “Absolute Volume” (in the developer settings).

5.Discourse Problems: Diagnostics and Solutions

If none of these things worked, the problem could be the hardware.

• 🧹 Pollution speaker - dust and pile block the membrane. Clean the speaker hole with a soft brush or compressed air.
• 💧 Moisture intake - even after drying, the oxidation of the contacts can turn down the volume.
• 🔧 Contact detachment is characteristic of devices after falls. Diagnosed by cod in dynamics.
• 🔋 Wearing membranes - in budget models (Redmi) 9A, POCO C31) The speakers are failing through 1.5-2 year-end.

For quick diagnosis:

1. Call the phone from another device and put your ear to the speaker — if the sound is clear but quiet, the problem is software.
2. Test music playback – if the music is loud and the calls are quiet, MIUI settings are to blame.
3. Check the sound in the headphones – if it is normal, the speaker is faulty.

⚠️ Warning: If you turn up the volume through an engineering menu or app, hoarseness or the sound "breaks", immediately return the standard settings! This is a sign that the speaker is physically unable to reproduce this volume level without damage.

6. Alternative solutions: vibration, LED, notifications on the screen

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

• 📳 Increased Vibration: In Settings → Sound and vibration → When you call, choose "Strong" or "Adaptive" mode on models with a linear vibrator motor (Xiaomi). 12T, POCO F4 GT) This will be more efficient than standard vibration.
• 💡 Notification LED: Activate in Settings → Notifications → LED lights. Select flashing mode for calls.
• 🔦 Screenlighting: Enable "Lift to Activate" (Settings) → Screen. → Lift for activation) – when the incoming call the screen will light up.
• 📢 Voice notifications: Apps like Google’s Sound Notifications let you know who’s calling, even if your phone is in your pocket.

For owners. POCO F3 GT Black Shark is a unique option — RGB-lighting when you call. Activated in Settings → Additionally. → Illumination.

7. Resetting the sound settings to factory

If after all the manipulations, the sound gets worse or there are distortions, return the settings to the factory settings, which will remove all user changes, including the parameters of the engineering menu.

Instructions:

1. Go to Settings → About the phone → Reset settings.
2. Select “Reset Sound Settings” (not a full reset!).
3. Confirm the action and restart the device.

Important: After reset, check:

• Volume level in Settings → Sound and vibration.
• No restrictions in Settings → Battery → Performance mode (sometimes energy saving reduces volume).
• Do Not Disturb Profile Activity (Settings → Sound and Vibration → Do Not Disturb).

💡

Before resetting, record the current sound settings (e.g., take a screen picture) to help quickly restore the individual settings after the procedure.
