Increase the volume of the speaker on Xiaomi Redmi Note 5 through the engineering menu: safe methods

Owners of Xiaomi Redmi Note 5 often face the problem of low volume of the speaker, especially in noisy conditions. MIUI The solution is often not the volume level you want, and third-party applications to amplify the sound either require root rights or are unstable.The solution lies in a hidden engineering menu that is available on all Xiaomi smartphones, but requires a cautious approach.

This article will discuss how to safely increase the volume of a speaker through an engineering menu without risking damage to the hardware of the device. We will look at two firmware options - based on Qualcomm Snapdragon 636 chips (global version) and MediaTek Helio. G85 (Chinese modifications, because the ways they access the settings are different, and you will learn about the possible consequences of incorrect changes and ways to return everything to its original state.

What is an Engineering Menu and Why You Need It

The Engineering Menu (or Engineer Mode) is a hidden settings section designed to test and calibrate the hardware components of a smartphone, and manufacturers including Xiaomi use it during the manufacturing and maintenance phase. In this menu, you can change the parameters that are not available in the standard interface. MIUI, including:

• 🔊 Volume levels of speakers (talk, multimedia, headset)
• 📡 Communication module settings (GSM, LTE, Wi-Fi, Bluetooth)
• 🔋 Battery and charging parameters
• 📱 Calibration of sensors (accelerometer, gyroscope, proximity sensor)

It's important to understand that the engineering menu is not designed for the average user, and some of the parameters here can cause hardware failures if you change them without understanding the consequences, such as exceeding the maximum volume level of the speaker can physically damage the membrane, which will require a replacement module.

However, with a competent approach, the engineering menu allows you to solve the problem of quiet sound without root rights or installing third-party applications, the main thing is to follow the instructions and not change the parameters that you do not know the purpose of.

Preparing for changes in settings: what to do in advance

Before you start changing the volume settings, follow a few mandatory steps, which will help avoid errors and make it easier to roll back to the original settings if the result does not suit you.

⚠️ Note: If your Redmi Note 5 is warranty-free, changes to the engineering menu can cause a service denial.

How to log into the engineering menu on Xiaomi Redmi Note 5

How you log in to the engineering menu depends on your device’s firmware and chipset, and the following are the current methods for both versions of the Redmi Note 5.

For firmware based on Qualcomm Snapdragon 636

The global and European versions of the smartphone use a Qualcomm chipset to open the engineering menu:

1. Open the Phone app.
2. Enter the combination: ##4636###.
3. In the menu that appears, select Engineer Mode (or Engineering Menu).
4. Go to the Hardware Testing → Audio section.

If the combination does not work, try an alternative method:

Settings → About Phone → Version of the kernel (click 5 times in a row)

For firmware based on MediaTek Helio G85

The Chinese versions of the Redmi Note 5 (such as the Redmi Note 5 Pro China) are equipped with a MediaTek chipset.

1. Open the Phone app.
2. Enter ##36446337## (or #364463## for some firmware).
3. Select Hardware Testing → Audio → LoudSpeaker Mode.

If none of the codes work, your firmware may have been modified. In this case, try installing the app. MTK Engineering Mode from Google Play (MediaTek only!).

⚠️ Note: Some custom firmware (such as LineageOS or Pixel Experience) can block access to the engineering menu, in which case the only way out is to return the stock. MIUI.

Step-by-step instructions for increasing the volume of the conversational speaker

Once you've successfully logged into the engineering menu, you can start setting the volume, and it's important to understand that we're only going to change the earpiece, not the loudspeaker, and that doing something wrong can cause you to distort the sound or damage the speaker.

For Qualcomm Snapdragon 636

Follow these steps:

1. In the engineering menu, go to Hardware Testing. → Audio → Normal Mode.
2. Select Type: Sph (Speak Speaker).
3. In the Value field, you will see the current volume value (usually 0 to 160 or 255).
4. Increase the value by 10-20 units (for example, from 120 to 140).
5. Press Set, then Save.
6. Restart the phone and check the volume.

If the sound began to be distorted or wheezing appeared, reduce the value by 5-10 units. The optimal range for the Redmi Note 5 is 130-150.

For MediaTek Helio G85

On MediaTek chipsets, the process is slightly different:

1. From the engineering menu, select Hardware Testing → Audio → LoudSpeaker Mode.
2. Go to the Speech tab (speech).
3. Find the Speech Vol or Sph Vol settings.
4. Increase the value by 5-15 units (maximum - up to 200, but it is recommended not higher than 180).
5. Save the settings and restart the device.

On MediaTek, you can also set the volume separately for Headset Mode and Ring Mode, but this does not apply to the conversational speaker.

⚠️ Warning: Changing Loudspeaker settings can cause membrane overheating or damage.Tune only Sph (talk speaker)!

💡

If the sound becomes too loud and distorted after the changes, try reducing the value by 5 units and restarting the phone, sometimes the effect only manifests itself after re-energizing.

Possible problems and solutions

Even if you change your settings carefully, you can have problems, and let's look at the most common ones and how to fix them.

1.The sound became hoarse or intermittent

This means you've exceeded the maximum volume level for your speaker.

• Return to the engineering menu and reduce the value by 10-15 units.
• If the wheezing is left, reset to the standard settings (usually the Reset button in the Audio menu).
• Check the speaker for physical damage (dust, moisture).

2.After the reboot, the settings reset

Some firmware MIUI They automatically reset the parameters of the engineering menu to fix the changes:

• Repeat the procedure and immediately check the volume (without restarting the phone).
• Use applications like BuildProp Editor (requires root) to write values in system files.
• Update. MIUI until the latest version - in new assemblies, this problem is less common.

3.The phone stopped detecting the speaker

This is a critical error that can occur when the parameters of the Audio Type are changed incorrectly.

• Reset all settings in the engineering menu to factory (Restore Default button).
• If it doesn’t help, reset through Settings. → Additionally. → Resetting settings (without deleting data).
• In extreme cases, you will have to refashion the device through Fastboot.

If none of these methods worked, contact the service center, and indicate that the problem occurred "independently" - the masters rarely check the engineering menu during warranty repairs.

💡

Before any changes to the engineering menu, write down the initial values of the parameters, which will allow you to quickly return everything back if something goes wrong.

Alternative ways to increase volume without an engineering menu

If you can't get on the engineering menu, or you're afraid of breaking something, there are a few alternatives. They're less effective, but they're safer.

1. Settings MIUI

In the standard settings Xiaomi Redmi Note 5 has hidden options for amplifying the sound:

• 🔊 Go to Settings. → Sound and vibration → Loudness.
• Activate the volume slider (if it is in your firmware).
• Turn on Adaptive sound – this automatically raises the volume in noisy conditions.

Third-party annexes

Some utilities allow you to increase the volume without root rights:

• 📱 Volume Booster – a simple sound booster with presets.
• 🎧 Precise Volume – allows you to adjust volume levels more accurately.
• 🔊 Sound Amplifier (from Google) – amplifies the sound for people with hearing impairments.

Note that apps run on top of system settings and can degrade sound quality, and they don't affect the speaker during calls -- just the multimedia.

3. Physical cleaning of the speaker

Often the silent sound is caused by clogging the speaker with dust or villi to clean it up.

• Use a soft brush or compressed air (balloon).
• Do not use sharp objects - this will damage the membrane.
• If the speaker is wet, dry the phone in rice or silica gel for 12-24 hours.

If the sound has not improved after cleaning, the problem may be a hardware malfunction (detachment of contacts, damage to the membrane), in which case only a replacement speaker will help.
