How to increase hearing in Xiaomi phone: from settings to repair

Bad hearing when calling Xiaomi is a common problem that can occur on both budget Redmis and Mi or POCO flagships. The reasons range from trivial volume settings to hardware malfunctions of the speaker or microphone. In this article, we will examine all possible solutions, from simple adjustments to the phone menu to radical measures like disassembling the device.

It's important to understand that low volume during a conversation and low media (music, video) are two different problems: the first is the speaker (also known as "audible"), the second is the multimedia speaker, and we'll focus on making the voice heard more, because it's more critical for everyday use, and if you have problems with sound in games or music, some of the tips will work, but you'll need to adjust.

Before you start repairing, check the obvious: whether you have Quiet Mode on (Settings → Sound and Vibration → Quiet Mode), whether the speaker hole is contaminated, or whether you use a cover that blocks the sound channels, which are often the cause of false alarms.

1. Checking basic volume settings

So, to start with, the simplest thing is to adjust the programming parameters, and MIUI has separate controls for the volume of calls, media and alarm clock, and often users accidentally hit the volume buttons during a conversation, lowering the level to a minimum.

How to check:

• 📞 When you call, press the up/down volume buttons, and a slider will appear on the screen that says "Call Volume." Make sure it's at its maximum.
• 🔊 Go to Settings. → Sound and vibration → Volume and manually adjust all sliders (especially "Call").
• 🚫 Turn off the Smart Volume Control feature in the same menu – it automatically reduces the sound depending on the surrounding noise.

In Xiaomi models based on Android 12+ (MIUI 13+) There's a hidden volume limit to protect your hearing, and to remove it, tap the icon on the volume menu. ⚙️ (gear) and turn off the option "Safe volume".

Cleaning speaker and microphone

Dust, hair and dirt particles are the main enemies of acoustic holes. In Xiaomi, the speaker is usually located at the top of the screen (near the front camera), and the microphone is located at the bottom, next to the USB-C connector.

How to clean:

• 🧹 Use a soft toothbrush (dry!) or a wooden toothpick to gently remove visible contaminants. Don't push hard - the membrane speaker is fragile!
• 💨 Take a can of compressed air (sold in electronics stores) and blow the holes with short presses. Keep the balloon vertical to avoid liquid.
• 🧴 For persistent contaminants, you can use a cotton swab dipped in alcohol (no more than 70%), but act extremely carefully.

⚠️ Warning: Never use metal objects (needles, pins) - they can damage the speaker's protective net. Also avoid wet wipes: liquid that gets inside will disable the speaker.

3. Checking for software failures

Sometimes the problem is MIUI system errors, such as when you update your firmware, you may have lost your audio settings or conflict with background processes.

Remedies:

• 🔄 Reboot your phone. Hold the power button for 10 seconds until the device turns off, then turn it on again. This will reset the audio driver's temporary errors.
• 📱 Reset the sound settings. Go to Settings. → Annexes → Application management → Three dots (menu) → Resetting the application settings, which will bring all audio parameters back to the factory.
• 🛠️ Clear the cache of telephony services. In the same menu, "Application Management" search for "Phone" and "Contacts", then click "Clear Cache".

If the problem has occurred after the MIUI update, try rolling back to the previous firmware version via Settings → About Phone → System Update → Three Points → Select the Service Pack. Download the old firmware from the official Xiaomi website (section "ROM") and select it manually.

4.Using an engineering menu for fine-tuning

Xiaomi has a hidden engineering menu where you can manually increase the volume of the speaker, a method that requires caution, as incorrect settings can damage the acoustics.

Instructions:

1. Open the Phone app and enter the combination: ##36446337###
2. You will be taken to the EMMC Test menu. Go to the Hardware Testing → Audio section.
3. Select Normal Mode → Receiver (Speak Speaker).
4. In the Level field, set the value from 140 to 160 (maximum 255, but it's dangerous!). Press Set.
5. Check the sound, then save the settings (Save).

If #36446337## doesn't work, try the alternative codes:

• #4636## → Phone Information → Perform a ping test (for some Redmi models).
• ##6484## → MB Test → Audio (for older devices on MIUI 10–11)

⚠️ Note: Setting a Level above 180 may cause sound distortion or damage to the speaker. If there is wheezing or crackling after the changes, return the factory settings immediately!

5. Checking hardware faults

If the software methods didn't work, it's probably hardware, and here are the most common malfunctions and their signs:

For self-diagnosis:

1. Call from another phone and check if you can hear the voice of the person in the headset (plug wired headphones), if the headphones sound normal - a problem in the conversational speaker.
2. Record a voice message and listen to it. If the recording is silent or jammed, the microphone is faulty.
3. Move the body of the phone during a conversation, and if the sound appears/disappears, it's a sign of poor plume contact.

💡

Before visiting the service center, back up your data via Settings → Additional → Backup and Reset. Repair may require a complete phone reset.

6.Alternative solutions: headphones and external devices

If repairs are delayed, and you need to call urgently, use bypass methods:

• 🎧 Wired headset. Connect any headphones with a microphone through 3.5 mm or USB-C. In most Xiaomi models, the sound will automatically switch to them.
• 🔊 Bluetooth headphones. Modern ones. TWS-Headsets (like Redmi Buds or Xiaomi AirDots) provide good audibility. Include them in Settings → Bluetooth.
• 📱 Speaker. Press the speaker icon to switch to the external speaker. Minus, people around you will hear the conversation.
• 🔗 Call forwarding. In settings. → SIM-maps and mobile networks → Call forwarding can be configured to another number.

For models that support Mi AI Assistant (such as the Xiaomi 12/13 series), you can use voice commands to control volume. Say, "Rise volume to maximum" - the system will execute the command even during a conversation.

7. When to contact the service center

If you've tried all the ways, but the problem remains, it's time to contact the specialists. Here are signs that you can't do without repairs:

• 🔇 Total lack of sound in the speaker (even at maximum volume).
• 🔊 Severe distortions: crackling, wheezing, intermittent sound.
• 💧 Traces of corrosion or moisture under the speaker grid.
• 🔌 The phone does not detect connected headphones or Bluetooth devices.

The cost of repairs in official service centers Xiaomi (in Russia for 2026):

• Replacement of the Speaker: 800–2500 ₽ (model-wise).
• Microphone replacement: 600–1800 ₽.
• Diagnosis: 300-500 ₽ (Frequently free if you agree to a repair).

Before the service visit:

1. Check the warranty status of the phone by IMEI on the Mi Verify website. If the warranty is valid, repairs can be free.
2. Check if the service uses original parts. In informal workshops, they often put cheap ones that quickly fail.
3. Ask about the time of repair. In official centers Xiaomi change the speaker is done in 1-3 days.

💡

Official Xiaomi service centers in Russia can be found through the map on the website mi.com/ru/service/location. Avoid workshops without a license – this is the risk of losing the warranty.
