How to increase the volume of the speaker on Xiaomi Redmi 7: safe and effective methods

Xiaomi Redmi 7 is a popular smartphone with good specs, but many users face the problem of low volume speakers, especially when listening to music, watching videos or talking in noisy places. In this article, we will discuss all possible ways to increase the volume on Redmi 7 β€” from standard settings to advanced methods using the engineering menu.

It's important to understand that factory volume limits are set for a reason: they protect speakers from overload and premature failure. However, if you're sure that your Redmi 7 can do more, you can try safe methods of amplifying sound. We'll look at both software and hardware nuances, and also warn about possible risks.

Why Redmi 7 has a quiet sound: the main reasons

Before you start to turn up the volume, it’s worth figuring out why the sound on the Xiaomi Redmi 7 can be quieter than expected.

  • πŸ”Š Factory restrictions MIUI β€” Xiaomi firmware often artificially lowers the maximum volume to protect speakers.
  • πŸ“± Pollution speaker – dust, pile, or moisture can physically block sound waves.
  • πŸ”§ Membrane damage speaker – over time or after falls, the sound quality deteriorates.
  • 🎧 Incorrect sound uniformity settings – some modes (such as Dolby Atmos) can lower the overall volume.
  • πŸ“² An outdated version MIUI β€” New updates often optimize sound profiles.

If the problem isn't physical failure, you can programmatically turn up the volume, and let's start with the simplest and safest ways.

⚠️ Warning: Before any sound manipulation, check to see if the speaker is covered with a cover or protective film, which often causes a quiet sound.

Method 1: Adjust sound through standard MIUI parameters

The first thing to try is to change the sound settings in the system itself. MIUI offers several options that can help:

  1. Activate Dolby Atmos Mode: Go to Settings β†’ Sound and Vibration β†’ Dolby Atmos. Turn on Mode and select the Music or Movie profile – these usually give a louder sound.
  2. Turn off volume limit for multimedia: In the same section, find Safe Volume and turn it off, which will allow you to raise volume above the recommended level.
  3. Change your audio profile: In Settings β†’ Sound and vibration β†’ Sound Profile Select Outdoors – this mode automatically increases the volume of notifications and calls.

It’s also worth checking if Do Not Disturb or Quiet mode is activated in the notification curtain, sometimes users accidentally turn them on, leading to a significant decrease in volume.

Method 2: Using third-party applications to amplify sound

If standard settings don't work, you can use specialized applications that work as amplifiers, changing frequency or bypassing system constraints.

  • 🎡 Volume Booster GOODEV β€” allows you to increase the volume on 20-30% It's a change in the uniformity of the sound. 7 and does not require root rights.
  • πŸ”Š Equalizer FX β€” equalizer app that can amplify low and high frequencies, making the sound louder and more saturated.
  • πŸ“± Precise Volume – gives access to more accurate volume settings, including steps that are hidden in the standard interface.

When using such applications, it is important to monitor the temperature of the smartphone. The amplification of sound can increase the load on the processor, which leads to overheating, and avoid maximum volume values in applications - this can distort the sound.

How to install and configure Volume Booster GOODEV:

  1. Download the app from Google Play.
  2. Launch it and give access to the sound settings.
  3. Move the Booster slider by 20-25% (it is not recommended to put more than 30%).
  4. Enable the Auto Boost option to automatically amplify when playing media.

⚠️ Note: Some sound amplification applications may conflict with MIUI, Check the reviews of Redmi 7 users before using.

Method 3: Engineering menu – hidden volume settings

For power users, it is possible to change the volume through the engineering menu, a method that requires caution, as the wrong settings can cause the speaker to break, but when used carefully, it can significantly increase the volume.

To get to the engineering menu on Redmi 7, follow the following steps:

  1. Open the Phone app.
  2. Enter the code ##36446337##
  3. Select Hardware Testing β†’ Audio β†’ LoudSpeaker Mode.

In this menu you will see several parameters responsible for volume:

  • Max Vol is the maximum volume (the default value is usually 140-160).
  • Min Vol is the minimum volume.
  • Type is a type of speaker (such as Speaker or Headset).

To increase volume, change the Max Vol value to 180-200 (not recommended to put above 200!). After changing, press Set and restart the smartphone.

ParameterDefault valueRecommended valueMaximum permissible
Max Vol (Speaker)150180200
Max Vol (Headset)120140160
Max Vol (Ring)130150170
What happens if you set Max Vol above 200?
At 200 or more, the Redmi 7 starts to run at its limits, which can lead to: - distortion of sound (wheezing, crackling), - overheating of the speaker, - physical damage to the membrane (rupture), In some cases, the sound can completely disappear, and you need to replace the speaker.

On Xiaomi Redmi 7 with MIUI 12 firmware and higher, the engineering menu can be blocked, in which case access will require unlocking the bootloader and installing custom recovery.

Method 4: Update firmware and reset settings

Sometimes the silent sound is caused by an outdated version of MIUI, and developers regularly release updates that optimize sound drivers and fix bugs to update the firmware:

  1. Go to Settings β†’ About the phone β†’ System update.
  2. Click Check for updates.
  3. If a new version is available, download and install it.

If the update didn’t help, try resetting the sound settings to factory:

  1. Open Settings β†’ System β†’ Resetting settings.
  2. Select Resetting Sound Settings (not a full reset!).
  3. Confirm the action and restart the smartphone.

This reset will return all audio profiles to standard values, which sometimes helps to eliminate software failures.

Before updating your firmware, back up your data through Settings β†’ Additional β†’ Backup and Reset. This will save your files in the event of a crash.

Method 5: Hardware Methods – Cleaning and Replacing the Dynamics

If the software methods fail, the problem may be the dynamics itself, and over time it gets clogged with dust or fails.

  • 🧹 Clean speaker: Use a soft brush or compressed air (a balloon) to remove dust from the speaker grille. Don't use sharp objects - they can damage the membrane.
  • πŸ”§ Contact check: If you're disassembling a smartphone, make sure the speaker plume is tightly connected to the motherboard. Sometimes the sound goes missing due to poor contact.
  • πŸ”„ Replacement speaker: If the speaker is damaged, it can be replaced. 7 The original speaker is around 300-500 Replacement is best entrusted to the service center.

Before you clean or replace the speaker, make sure that it's the speaker that's the problem, and then play the sound through your headphones, and if it's loud and clear, it's the dynamics.

⚠️ Warning: When you disassemble the Redmi 7 yourself, you risk damaging the plumes or losing water protection (if any.

What not to do when you increase the volume on the Redmi 7

In pursuit of loud noise, users often make mistakes that lead to a breakage of the smartphone.

  • 🚫 Install Max Vol above 200 on the engineering menu, almost guaranteed to damage the speaker.
  • 🚫 Use root-right applications without experience. Getting root incorrectly can make your smartphone tick.
  • 🚫 Blowing the speaker with your mouth or vacuum, which can drive the dust deeper or damage the membrane.
  • 🚫 Ignore overheating of the smartphone. If the case becomes hot, immediately turn down the volume.

Also, you don't need to use multiple methods of amplifying sound at the same time (e.g., an engineering menu + an amp application), which creates a double load on the speaker.

The safest way to turn up the volume is to use standard MIUI settings or applications without root rights.
