Are you missing important calls because your smartphone vibrates in your pocket and the melody is barely audible? The problem of low call volume on Android is familiar to many - especially owners of budget models or devices with worn-out speakers. But don’t rush to attribute this to hardware limitations: in 80% of cases, the volume can be increased programmatically without resorting to repairs.

In this article we will look at all possible methods - from basic volume settings to working with engineering menu and specialized applications. You will learn how to bypass manufacturer restrictions, why the volume may decrease spontaneously, and what to do if standard methods do not help. And for owners of old smartphones (Samsung Galaxy S8, Xiaomi Redmi Note 5 etc.), we provide separate recommendations for restoring the factory volume.

Important: some methods require root access or activating the developer mode. If you are not ready to experiment, focus on the first three sections with safe solutions.

1. Checking basic volume settings

Start with the obvious: perhaps the ringer volume simply went wrong after updating the system or installing a new application. On most smartphones (Samsung, Xiaomi, Realme), the path to the settings is the same:

  1. Open Settings → Sound and vibration (or Sound).
  2. Find the slider Ringer volume (sometimes divided into "Melody" and "Vibration").
  3. Move it to the far right position.
  4. Activate the option Increasing volume when pressing buttons (if available).

On some firmware (for example, MIUI from Xiaomi) there is a separate section Call settingswhere you can select a melody with a higher amplitude. Try standard signals Ring_Classic or Ring_Loud —they are usually louder than custom ones.

⚠️ Attention: If, after changing the settings, the volume resets again, check battery saving applications (for example, Battery Saver or DU Battery). They can automatically lower the volume to “optimize” power consumption.

2. Using Do Not Disturb mode and profiles. sound

Paradoxically, sometimes the user himself limits the volume of the call by activating the Do not disturb (DND) mode or selecting a quiet profile. It’s easy to check:

  • 🔊 Drag the notification panel down and make sure that icon Do not disturb (usually a crescent) is not active.
  • 📱 On Samsung press the volume button down → select Sound (not "Vibration" or "No sound." data-i="83">Normal
  • 🎵 On Xiaomi open Settings → Sound → Sound Profiles and select Ordinary.

If you use a profile Quiet or Meeting, some calls may arrive without sound. For example, in Huawei in the profile Sleep all notifications are disabled by default, except alarm clock.

Brand Path to sound profiles Recommended profile
Samsung Settings → Sound and vibration → Sound mode Sound
Xiaomi/Redmi Settings → Sound → Sound profiles Normal
Realme/Oppo Settings → Sound and vibration → Sound modes General
Google Pixel Settings → Sound → Do Not Disturb mode Disable DND
💡

On some smartphones (for example, Sony Xperia) sound profiles are called "Scenarios". Select the scenario "On the street" - it automatically increases the volume of the call by 20-30%.

3. Increase the volume through the engineering menu (without root)

If the standard settings do not help, try engineering menu - a hidden section of Android where you can manually configure the settings. speakers. This method works on 90% of smartphones based on processors Qualcomm (including Samsung Galaxy A, Xiaomi Poco, OnePlus Nord).

Instructions:

  1. Open the application Phone and enter the combination: 
    ##4636##

    (on some models Samsung used #0#).

  2. Select Phone information (or Hardware Testing).
  3. Scroll to section Audio → Loudspeaker Mode.
  4. Set the value Level to maximum (usually 160 or 255).
  5. Save changes and restart the device.
⚠️ Attention: Do not change the parameters in the Microphone or Earpiece sections - this may lead to distortion of the sound in conversations. Also avoid values above 255: on some smartphones this causes wheezing in the dynamics.
What to do if the engineering menu does not open?

If nothing happens after entering the code:

1. Try alternative combinations: ##36446337## (for Mediatek) or ##8255## (for Google Pixel).

2. Install the application MTK Engineering Mode (for processors Mediatek) or Qualcomm EngineerMode from Google Play.

3. On new versions of Android (12+), the engineering menu may be blocked. In In this case, only root or ADB commands will help (see section 6).

4. Applications to increase the volume of the call

If you don’t want to delve into the settings, use specialized utilities. They work on top of the system and can increase the volume up to 200% of the standard one:

  • 🔊 Volume Booster GOODEV - a simple booster with. presets for calls, music and notifications. Supports Android 5.0+.
  • 🎵 Precise Volume - allows you to fine-tune the volume for each type of sound (including alarms and system notifications).
  • 📱 SoundAssistant (from Samsung, but works on other brands) - gives access to hidden sound settings, including separate adjustment for left/right dynamics.
  • 🔧 Equalizer FX —in addition to increasing the volume, it offers an equalizer to improve sound quality.

How to use:

  1. Install the application from Google Play.
  2. Launch it and provide access to sound settings.
  3. B section Ringtone or Call move the slider to maximum.
  4. Activate the option Amplifier (if yes).

✅ Make sure that there are no other sound applications on the system (conflicts may reduce the volume)

✅ Check reviews - some boosters contain advertising that interferes with operation

✅ Set up exceptions for the booster in battery optimizer (otherwise the system may suspend it)

Warning: long-term use of boosters at maximum volume can shorten the life of the speakers. If wheezing appears after installation, reduce the gain level to 150%.

5. Cleaning the speaker and checking for hardware problems

If software methods do not work. helped, the reason may be a hardware malfunction. Dust, moisture or mechanical damage often lead to muffled sound. What to do: dirty speaker or hardware malfunction. Dust, moisture or mechanical damage often lead to muffled sound. What to do:

  • 🧹 Cleaning the speaker: Use a soft brush (for example, for makeup) or a can of compressed air. use alcohol or sharp objects!
  • 🔊 Checking the sound: Turn on the video on YouTube and listen - if the sound is distorted or missing from one of the speakers, there is a hardware problem.
  • 📱 Speaker test: Enter the code in the phone application: 
    #0#

    In the menu Speaker check if the top/bottom speaker is working.

If the speaker is physically damaged (for example, after being dropped or exposed to water), it will have to be replaced. Average repair cost:

  • Samsung Galaxy A52 — 1 200–1 800 ₽;
  • Xiaomi Redmi Note 10 — 800–1 500 ₽;
  • Google Pixel 6 — 2 500–3 500 ₽.
⚠️ Attention: On smartphones with stereo speakers (for example, Samsung Galaxy S22 or OnePlus 9 Pro) the problem may be in one of the modules. Check the sound separately for the upper and lower speakers through the test menu.

6. Advanced methods: ADB and root access

For advanced users who are willing to take risks, there are ways to increase the volume through ADB (Android Debug Bridge) or using root access. These methods give maximum control, but require caution.

Method 1: ADB commands (without root)

  1. Activate Developer mode (click on Build number 7 times phone settings).
  2. Enable USB debugging in the developer settings.
  3. Connect the phone to the PC and run the command: 
    adb shell settings put system volume_music 15

    (replace music with ring for calls, and 15 with a value from 0 to 15).

Method 2: Editing the mixer_paths.xml file (requires root)

This file contains volume limits for all audio devices. To change it:

  1. Install a file manager with root access (for example, Root Explorer).
  2. Go to the path /system/etc/ and find the file mixer_paths.xml (or mixer_paths_tasha.xml for Qualcomm).
  3. Open the file in a text editor and find the lines with speaker or ring.
  4. Increase the parameter values max by 20-30% (for example, from 80 to 100).
  5. Save the file, install rights 644 and reboot the device.
💡

Changing mixer_paths.xml gives the most noticeable increase in volume, but if the settings are incorrect, it can lead to sound distortion or damage to the speaker. Always make a backup copy of the file before editing!

7. notifications, Bluetooth

If you can’t increase the volume, consider alternative ways not to miss a call:

  • 🔄 Amplifier vibration: In the sound settings, select Intense vibration or install the application Vibration Tuner to create custom patterns.
  • 💡 Light notifications: On some smartphones (for example, Samsung Galaxy s Always On Display) you can set the screen to blink when making a call.
  • 🎧 Bluetooth headset: Connect wireless headphones - the sound will be transmitted there, and not to the phone speaker.
  • 🔔 Duplication for smart watches: If you have Mi Band, Galaxy Watch or Apple Watch, turn on call alerts in the accompanying application.

For owners Samsung there is a useful function Adaptive sound (Settings → Sound and vibration → Sound quality and effects) It automatically increases the volume in noisy places.

8. Common causes of spontaneous volume reduction

If the ringer volume is periodically reset, look for the reason in one of these factors:

  • 🔋 Battery saving modes: When activated Adaptive battery or Ultra mode the system may limit the volume. Disable optimization for the application Phone.
  • 📲 System updates: After major updates (for example, from Android 11 to Android 12the sound settings may be reset. Check them after the update.
  • 🎵 Conflicting applications: apps like Spotify, VK Music or YouTube Music sometimes they capture the audio channel. Close them before testing the volume.
  • 🛠️ Reset settings: If the problem appeared after resetting to factory settings, Perhaps the user sound profiles have not been restored.

To exclude the influence of third-party applications, boot the phone into Safe Mode (press the power button → Safe ModeIf the volume is normal, one of the installed ones is to blame). applications.

💡

On smartphones with Android 10+ there is a function "Sound Adaptation" (Settings → Accessibility → SoundIt automatically adjusts the volume to the surrounding environment, but sometimes it doesn’t work correctly. Try disabling it.
