How to increase volume on Xiaomi Redmi 7: from basic settings to hidden features

Xiaomi Redmi 7 is one of the most popular budget smartphones of the brand, but many users are faced with the problem of insufficient volume of speakers or headphones. The reasons can vary from factory limitations of MIUI to hardware features of the model. In this article, we will discuss all possible ways to increase the volume, from standard settings to advanced methods using engineering menus and third-party applications.

It is important to understand that increasing the volume above factory limits can affect sound quality and even damage the speakers with prolonged use. Therefore, before applying any changes, we recommend testing them at minimum volume and monitoring for distortion. If you use Redmi 7 with custom firmware, some methods may not work or require adaptation.

This article is relevant for all Redmi 7 modifications (including Redmi 7A), but some points may differ depending on the version of MIUI (for example, in MIUI 12 and the newer way to the audio settings has been changed). If your smartphone runs on Android 9 Pie or Android 10 with the shell of Xiaomi, all instructions apply.

1. Basic volume settings in MIUI

Before resorting to radical methods, check the standard sound parameters. MIUI has several hidden options that can improve the perception of volume without risk to the equipment.

Open Settings → Sound and vibration. The following adjustments are available here:

• 🔊 Media volume is a slider for music, video and games. Make sure it's set to maximum.
• 🎧 Headphone amplification: This is an option when you connect wired or Bluetooth headphones, turn it on to turn it up 10-15 times%.
• 📱 Adaptive sound – the feature automatically adjusts the volume to ambient noise (not available on all versions) MIUI).
• 🔇 Don’t disturb – check if this mode is activated, as it can block notifications and turn down the volume.

Pay special attention to the item Sound Quality (could be called Sound Effects or Equalizer), where you can choose presets like Bass or Rock, which visually increase volume by amplifying low frequencies. However, this is not always useful: on cheap Redmi 7 speakers, such settings can cause wheezing.

⚠️ Warning: If the presets change, return the settings to default. Prolonged listening to distorted music can damage the speakers.

2.Use of the Engineering Menu (MTK Engineer Mode)

Redmi 7 is built on a Qualcomm Snapdragon 632 processor, but in some regions sold a version with a MediaTek Helio P60/P70 chipset (for example, Redmi 7 for India). If your smartphone is on MediaTek, you can use the engineering menu to fine-tune the volume. For Snapdragon, this method is not suitable - move to the next section.

To open the engineering menu:

1. Open the Phone app.
2. Enter the combination: ##3646633## (some versions of MIUI may require ##4636##).
3. Go to the Hardware Testing → Audio section.

In the Audio menu you will see several categories:

• 🔈 Normal Mode - Standard Mode (Speaker, microphone).
• 🎧 Headset Mode - Headphone Mode.
• 📞 LoudSpeaker Mode – loud communication.

To increase the volume:

1. Select Normal Mode (for speaker) or Headset Mode (for headphones).
2. In the Value field, set the value from 140 to 160 (maximum 255, but it is dangerous!).
3. Press Set, then restart the smartphone.

⚠️ Warning: Setting a value above 160 can cause sound distortion or damage to speakers.On Redmi 7 with MediaTek Helio P60 the safe limit is 150, for P70 — Exceeding these values does not guarantee a volume increase, but increases the risk of breakage.

Record the current volume values (take a picture of the screen)

Set a value not higher than 150 for the first test

Check the sound at minimum volume before increasing

Reboot your phone after the changes

3. Sound amplification applications

If you're not getting the standard settings and the engineering menu, you can use third-party apps, and they work on two principles:

1. Software amplification – increase the volume due to sound processing algorithms (may worsen the quality).
2. Change system files – modify MIUI settings (require root rights).

Best apps for Redmi 7 without root:

• 🎛️ Volume Booster GOODEV — a simple booster with presets for different scenarios (music, games, calls).
• 🔊 Equalizer FX — allows you to fine-tune the equalizer and increase the volume by 20-30% without distortion.
• 🎧 ViPER4Android — Advanced audio processor (requires installation via Magisk for full functionality).

To install ViPER4Android on Redmi 7:

1. Download APK from the official website (vipersaudio.com).
2. Install the application and open it.
3. Enable the Enable ViPER4Android option and select the Legacy Mode driver (for MIUI).
4. In the Master Limiter section, increase the value to 5-7 dB to amplify the sound.

If the sound becomes hoarse or intermittent after installing the app, reduce the Master Limiter value or turn off the Convolver and Tube Simulator effects.

💡

Before installing any sound booster, back up your MIUI settings in Settings → About Phone → Backup. This will help restore the original settings if the sound is gone completely.

Hardware methods: cleaning speakers and replacing the grid

Sometimes the problem with low volume is not software constraints, but physical pollution. Redmi 7 speakers are located on the bottom of the smartphone and often get clogged with dust, pile or particles from your pocket, which leads to a muffled sound, even if the volume is at its maximum in the settings.

To clean the speakers:

• 🧹 Use a soft brush (for example, for drawing) or a toothpick with cotton wool. Carefully run along the speaker grille without pressing.
• 💨 A compressed air balloon (to clean keyboards) will help blow out dust. Keep the balloon upright to avoid fluid intrusion.
• 🔊 Check the sound after cleaning – if it’s cleaner but the volume hasn’t gone up, the problem isn’t pollution.

If the speaker is damaged or the grid is deformed, you can try to replace it. For the Redmi 7, original parts with the MDY-09-001 article (bottom grille) or universal counterparts are suitable. The cost of replacing in the service center is from 500 to 1000 rubles.

⚠️ Warning: If the speaker starts wheezing after cleaning or the sound is completely gone, you may have damaged the membrane — MDY-09-002 for Redmi 7).

5. Update MIUI and reset settings

Sometimes low volume is associated with software bugs in a particular version of MIUI. Xiaomi regularly releases updates to fix sound problems.

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

If the problem persists, it may be the cache of the audio system to clean it up:

1. Go to Settings → Applications → Application Management.
2. Find Media Storage and click Clear Cache.
3. Do the same for Google Play Music (if installed) and MIUI Music.

6.Alternative solutions: Bluetooth amplifiers and external speakers

If none of these methods worked, consider external audio amplification devices, which is true if you often listen to music or watch videos in noisy places.

Options:

• 🎧 Bluetooth amplifier (e.g. FiiO) BTR3K or SoundMagic ES100) — connects to the smartphone via Bluetooth and amplifies the signal before transferring to headphones.
• 🔊 Portable speakers (e.g. Xiaomi Mi Portable Bluetooth Speaker) – connect via Bluetooth or 3.5mm connector.
• 🎤 FM-transmitter (e.g. Nulaxy) KM18) — transmits sound to a car tape recorder or stationary acoustics.

Redmi 7 is best suited for devices that support aptX or AAC – these codecs provide minimal quality loss when transmitted over Bluetooth. If you use wired headphones, look for amplifiers with a 3.5 mm connector (for example, FiiO A1).

The cost of such devices starts from 1000 rubles, but they are guaranteed to solve the problem of low volume without risk to the smartphone. In addition, external speakers or headphones with an amplifier often sound better than the built-in Redmi 7.

💡

If you often listen to music at maximum volume, an external amplifier or speaker will not only improve the sound, but also prolong the life of the smartphone speakers.
