Why you can’t hear your interlocutor in a Xiaomi phone on Android - a complete analysis of problems and solutions

Are you calling about an important matter, but instead of the interlocutor’s voice, you hear only silence or a barely perceptible whisper? The problem when I can’t hear the interlocutor on a Xiaomi phoneoccurs more often than it seems - and the reasons can lie either in trivial settings or in serious hardware faults. In this article we will analyze all possible scenarios: from MIUI software failures to physical damage to the speaker, and also give clear instructions on how to diagnose and fix the problem yourself.

Feature smartphones Xiaomi (including the Redmi, POCO i Milines) - their close integration with the proprietary MIUI shell, which sometimes conflicts with Android system services. For example, after updating the firmware, sound routing may go wrong, and incorrect settings Bluetooth or VoLTE can completely “muffle” the voice of the interlocutor. But do not rush to take your phone to the service: in 80% of cases the problem can be solved in 5 minutes, following our recommendations.

Important: if you encounter a problem after the phone falls, mechanical impact or contact with liquid - go straight to the section about hardware faults. In other cases, start with software diagnostics.

1. Checking the basic sound settings and modes

The first thing to rule out is random volume change or activating special modes. In Xiaomi there are several "traps" due to which the sound during calls may disappear:

• 🔇 Call volume is reset to zero is a separate slider in the control panel that is not associated with media sound.
• 🚫 Do Not Disturb mode or DND (Do Not Disturb) blocks all notifications, including the sound of calls.
• 🎧 Active A Bluetooth device —the phone can redirect sound to the headphones, even if they are turned off.
• 📱 Profile "In your pocket" (in some models POCO) automatically mutes the sound when the sensor approaches.

How to check:

1. During a call, press the button Volume up —a slider with a tube icon (not a musical note!) should appear on the screen.
2. Open Settings → Sound and vibration → Not disturb and make sure the mode is disabled.
3. Pull the notification curtain down and check if the icon Bluetooth or Headphones is active.
4. Reboot the phone - sometimes a failure in the service com.android.phone leads to "deafness".

Make sure the call volume is not at zero|Disable Do Not Disturb mode|Check connected Bluetooth devices|Reboot your phone-->

If after these steps the sound does not appear, proceed to the next section. If the problem occurs only with a specific interlocutor, perhaps the culprit is communication operator (more on this below).

2. Failures in MIUI firmware and update conflicts

The proprietary shell MIUI is known for its “surprises” after updates. Most often, the sound during calls disappears due to:

• 🔄 Unsuccessful firmware update —especially relevant for beta versions or manual firmware through Fastboot.
• 📱 Conflict with Google Phone —the standard “Phone” application can block the sound if installed over the native one Mi Dialer.
• 🗑️ Clogged cache system applications responsible for sound (com.android.phone, com.miui.player).

How to fix:

Method 1: Clearing the system application cache

1. Go to Settings → Applications → Manage applications.
2. Find and open Phone (or Mi Dialer), then tap Storage → Clear cache.
3. Repeat for applications Contact and Settings.

Method 2: Reset network settings

Sometimes it crashes settings VoLTE or VoWiFi causes no sound. To reset them:

1. Open Settings → SIM cards and mobile networks.
2. Select your SIM card and click Reset network settings.
3. Restart the phone and check the sound.

Method 3: Rollback update or flashing

If the problem appeared after updating MIUI, try:

• Roll back to the previous one versions via Settings → About phone → System update → Three dots → Select update package (if a backup is saved).
• Install the firmware again via Fastboot (instructions for experienced users).

MIUI updates|Installing a new application|Connecting a Bluetooth device|Falling/impacting the phone|On its own, for no apparent reason-->

⚠️ Attention: If you use custom recovery (for example, TWRP), reset the cache through it (Wipe → Dalvik Cache) may help, but increases the risk of data loss. First try the standard methods.

3. Problems with the SIM card and telecom operator

If the sound disappears only when making calls via the mobile network (and in WhatsApp or Telegram everything works), the culprit may be telecom operator or incorrect SIM card settings. Typical reasons:

• 📶 Lack of VoLTE support — without this technology, the sound may be transmitted with distortion or disappear altogether.
• 🔄 Incorrect APN settings —especially after changing the operator or tariff.
• 🚫 Service blocking by the operator (for example, with a negative balance or suspected fraud).

How to check:

Step 1: Enable VoLTE

1. Go to Settings → SIM cards and mobile networks → [Your SIM] → Enable VoLTE.
2. If the option is missing, update the firmware or contact your operator - some tariffs do not support VoLTE.

Step 2: Reset APN settings

1. Open Settings → SIM cards and mobile networks → Access points (APN).
2. Click on the three dots in the upper right corner and select Reset to default.
3. Reboot the phone.

Step 3: Check the balance and service status

Sometimes operators temporarily disable voice communications when:

• Negative balance (even if the Internet is working).
• Activation of the "Data Only" mode (for example, Tele2 or Yota).
• Suspicion of fraud (calls to short numbers, bulk SMS).

To make sure that the problem is not on the side operator:

1. Call the operator's short number (for example, *111# for MTS). If there is sound, the problem is in your SIM.
2. Try to call from another SIM card (for example, a friend or a second one) slot).

Operator	Short number for verification	Common reason for blocking
MTS	*111#	Negative balance, unpaid services
Beeline	*110#	Activation of the "Internet Only" option
MegaFon	*105#	Blocking for suspicious activity
Tele2	*155#	Expired SIM card expiration date

⚠️ Attention: If you use virtual operator (for example, Tinkoff Mobile or SberMobile), check if the "Data only" option is activated. Sometimes restrictions on voice communication are hidden in their personal account.

4. Hardware faults: speaker, microphone, cable

If software methods do not help, the problem is most likely hardwareIn smartphones Xiaomi the following most often fail:

• 🔊 Earpiece speaker - is responsible for the sound of the interlocutor (not to be confused with the bottom speaker for music!).
• 🎤 Microphone - if the interlocutor does not hear you, and you do not hear him, the problem may be in the microphone cable.
• 🔌 Audio jack cable —even if you do not use 3.5 mm, its damage can affect the sound.
• 💧 Oxidation of contacts after moisture gets in (even if the phone does not sink, condensation can accumulate inside).

How to diagnose:

Test 1: Checking the earpiece

1. Call another phone and turn it on speakerphone. If there is sound, there is a problem in the conversational speaker.
2. Put the phone to your ear and listen for wheezing, crackling or quiet background noise this is a sign of physical damage.

Test 2: Checking the microphone

1. Record a voice message in WhatsApp or Dictaphone. If the recording is quiet or absent, the microphone is faulty.
2. Try making a call in speakerphone mode. If the other person hears you only this way, the problem is in the lower microphone.

Test 3: Visual inspection

• Shine a flashlight at talking grill (top of the screen) - if dust, moisture or deformation is visible, the speaker is damaged.
• Check that it is not whether the screen comes off from the body - this may indicate damage to the cable.

What to do if the phone fell or got wet?

If the phone has been subjected to mechanical stress or contact with liquid, even slight, there is a high probability of oxidation of the contacts on the motherboard. In this case, independent repair is almost impossible - professional ultrasonic cleaning or replacement of components is required. Take the device to a service center, indicating the exact reason (drop/moisture), so that the technician can diagnose the board.

If the diagnostics confirm a hardware fault, you have two options:

1. Contact the service center (official Xiaomi or a verified private technician). Repair cost:
• Replacement of speaker: 1,500–3,000 RUR.
• Replacement of microphone: 1,000–2,500 RUR.
• Repair cable: 2,000–5,000 ₽ (depending on the model).

Independent replacement (only if you are confident in your skills!). For popular models (Redmi Note 10, POCO X3), spare parts and instructions are available for sale on YouTube.

⚠️ Attention: If the phone is under warranty, do not open it yourself this will void the warranty. Contact an authorized service Xiaomi with a receipt and box.

5. Conflicts with applications and access rights

Sometimes the sound during calls is blocked third-party applications, especially those that:

• 🛡️ Have access to telephone functions (antiviruses, spam blockers).
• 🎵 Control sound (equalizers, voice modifiers).
• 🔒 Use special features (for example, applications for people with hearing impairment).

How to find the culprit:

Method 1: Safe Mode

1. Hold the button power until the shutdown menu appears.
2. Press and hold Turn off poweruntil you are prompted to go to Safe mode.
3. Only system applications work in this mode. Call someone - if the sound appears, third-party software is to blame.

Method 2: Check permissions

1. Open Settings → Applications → Manage applications.
2. Sort applications by installation date (first new).
3. Check which of them have permissions Phone, Microphone or Changing system settings.
4. Disable rights of suspicious applications or remove them.

Method 3: Reset permissions

If you do not want to remove applications, reset their permissions:

1. Go to Settings → Applications → Permissions.
2. Click on the three dots in the upper right corner and select Reset application permissions.

Typical "culprits":

• Truecaller —can block sound when detecting spam.
• Dolby Atmos or Equalizer — conflict with the system sound settings.
• Applications for recording conversations —can “take over” the sound.

6. Specific problems of Xiaomi models

Some models Xiaomi have unique bugsrelated to sound during calls. Here are the most common:

Model	Problem	Solution
Redmi Note 8/8 Pro	Sound disappears after updating to MIUI 12.5+	Roll back on MIUI 12 or reset the network settings
POCO X3 NFC	Quiet sound in the speaker due to a defective cable	Replacing the cable in the service (warranty case)
Mi 10/10 Pro	Conflict with Google Phone when using two SIM cards	Install the native "Phone" application from Xiaomi
Redmi 9/9A	The sound disappears when connected to 4G (problem with VoLTE)	Disable VoLTE or update the firmware

If your model is in the table, try the proposed solution. If not, check the forums (for example 4PDA or Mi Community) for similar complaints. Users often find workarounds for specific devices.

Important: In models POCO F3 and Xiaomi 11T there is a microphone defect that manifests itself after 6-12 months of use. If the warranty is still valid, contact the service - this is a known problem with the batch.

7. Alternative methods of communication during repairs

While you are diagnosing or repairing your phone, you can temporarily use alternative communication channels:

• 💬 Messengers with voice calls: WhatsApp, Telegram, Viber.
• 📞 IP telephony: Skype, Zoom, Google Meet (allow you to call regular numbers).
• 📱 Second SIM card: Insert it into another phone or use the slot for the second SIM in your Xiaomi (if it works).
• 🔄 Call forwarding: Set up forwarding to another number via Settings → SIM cards → Call forwarding.

How to set up call forwarding:

1. Open Settings → SIM cards and mobile networks.
2. Select your SIM card and click Call forwarding.
3. Specify the number to which incoming calls will be forwarded.
4. Activate the option Always redirect.

If forwarding does not work, check:

• Whether your operator supports this service (some virtual operators have it disabled).
• Are there enough funds in the account (some operators charge a fee for forwarding).

FAQ: Frequently asked questions about the problem with sound in Xiaomi

Why in Xiaomi you can’t hear the interlocutor only on speakerphone, but everything is fine on the handset?

This is a typical problem c lower speaker, which is responsible for speakerphone and media sound. Reasons:

• Clogged speaker with dust (clean with a soft brush).
• Damage to the speaker cable (often after a fall).
• Failure in settings Dolby Atmos (turn it off in Settings → Sound).

If the speaker is clear, but there is no sound, a replacement is required.

After updating MIUI, the sound on calls disappeared. How to return the old version?

Rolling back the firmware possible, but associated with risks. Instructions:

1. Download the old version of MIUI for your model from the website en.miui.com.
2. Go to Settings → About phone → System update → Three dots → Select update package.
3. Select the downloaded file and confirm the rollback.

⚠️ Warning: Rollback may lead to data loss. Make a backup first. Settings → Advanced → Backup.

The interlocutor can hear me, but I can’t hear him. What's wrong?

This indicates a problem with Earpiece speaker (top speaker, next to the front camera). Possible reasons:

• Physical damage to the speaker (crackling, wheezing).
• Failure in sound routing (try resetting the network settings).
• Conflict with an application that blocks sound (check in safe mode).

If the speaker is working, but there is no sound, the problem is in the firmware or cable.

There is sound, but it is very quiet. How to strengthen?

Try these methods:

1. Turn on Sound Boost in Settings → Accessibility → Hearing → Sound Boost during calls.
2. Disable Dolby Atmos or other sound effects in Settings → Sound.
3. Check whether the speaker grill is covered with a case or film.
4. Use headphones or a Bluetooth headset for a temporary solution.

Can you fix the speaker yourself?

Theoretically yes, but this requires:

• Skills in working with small electronics (soldering iron, tweezers).
• Original spare parts (the speaker for Xiaomi costs 300–1000 ₽).
• Tools: screwdrivers, a mediator for opening the case, a hair dryer for softening the glue.

For most users, it is easier and cheaper to contact the service. The exception is models with a removable back cover (for example, Redmi 4X), where replacing the speaker takes 10 minutes.
