I can’t hear the interlocutor when calling Xiaomi: reasons and solutions

The problem of not hearing a caller on a Xiaomi smartphone is more common than you think, and it can happen on any model, from the budget Redmi Note 12 to the flagship Xiaomi 14 Ultra. The reasons range from the banal (stuff in dynamics) to the technical (damage to the audio chip).

It's important to understand that the problem isn't always with the phone itself, sometimes it's the carrier, the poor coverage, or even the conversational settings, but 80 percent of the time, the solution is on the user side, and we've put together 12 proven ways to bring sound back to the conversational speaker without having to go to the service center.

If you’re facing this problem for the first time, start with the simplest steps — they often solve the problem in 2-3 minutes. For experienced users, we’ve prepared a section with hardware malfunction diagnostics and hidden MIUI settings that few people know about.

1. Checking basic sound settings

The first thing to do is make sure that the problem isn't with the basic settings, and often users accidentally change the volume or activate modes that block the sound when they make calls.

Open the Quick Settings Panel (swipe down from the top edge of the screen) and check:

• 🔊 Volume level - the slider should be at a maximum or at least above 50%, sometimes it gets knocked off after the headphones are connected.
• 📵 Do Not Disturb - if it's active, calls may come without sound. → Notifications and status bar → Don't disturb.
• 🎧 Connected devices – the phone can automatically switch the sound to a Bluetooth headset or speaker even if it is turned off.

Pay special attention to Settings → Sound and vibration → Media Volume. This separate setup sets the volume for calls, notifications and multimedia, and sometimes resets after the MIUI update.

2. Diagnostics of conversational dynamics

If the basic settings are fine, but the interlocutor is still not heard, the problem may be in the dynamics itself. On Xiaomi smartphones, a separate conversational speaker (aka "top speaker"), which is located next to the front camera, answers the sound during calls.

How to check its performance:

1. Call another phone and listen to whether the sound is coming from the top of the screen.
2. Turn on a recording of a voice message on WhatsApp or Telegram and hold the phone to your ear – if there is a sound, but very quiet, the speaker is clogged with dust.
3. Try to play the sound through an external speaker (bottom) – if everything works there, the problem is precisely in the conversation module.

A common cause is speaker pollution: Dust, hair, or even moisture droplets can block sound. Carefully clean the speaker hole with a soft brush (like a toothbrush) or compressed air. Don't use sharp objects, it can damage the speaker grid.

💡

If the sound came after cleaning, but then disappeared again, the problem is the tightness of the case. On IP53 models (such as the Redmi Note 12 Pro+), the sealing gums wear out over time, and the dust gets in.

3. Checking the microphone and network settings

If the person you're talking to can't hear you, and you're the person you're talking to, the microphone is a problem, but there are times when, because of a network failure or phone settings, the sound is only transmitted one way.

• 📡 Quality of communication – if you have 1-2 If you divide the network, the sound may be interrupted or lost. 3G instead 4G/5G In Settings → SIM-maps and mobile networks → Preferred type of network.
• 🔄 Switching SIM-If you have two-sim Xiaomi, try calling another one. SIM. Sometimes the operator blocks voice calls due to tariff issues.
• 🎤 Microphone test - record a voice message or use the Dictaphone app. If the recording is silent or disturbed, the microphone is defective.

Some models (such as the POCO F4 or Xiaomi 12T) have a separate noise-cancellation microphone, and if it fails, the person will hear you very quietly, despite the main microphone working, and you can only check this in the service center.

4.Reset network and sound settings

If the problem occurs after a MIUI update or a change in settings, resetting the network or audio settings will help, and it won't delete your data, but it will return the network and audio settings to the factory settings.

How to reset your network settings:

1. Go to Settings. → SIM-maps and mobile networks.
2. Click Reset Mobile Network Settings.
3. Confirm the action and restart the phone.

To reset the sound settings:

1. Open Settings → System and device → Resetting settings.
2. Select Reset sound settings (some firmware may not have this item).
3. If there is no item, reset all settings to factory, but pre-return backup.

After the reset, check if the sound is coming, and if it's not, it could be the firmware or the hardware.

5. Hardware malfunctions: when you need to service

If all software methods have been tried, but the interlocutor is still not heard, the problem is likely hardware.

Especially vulnerable to such failures models with a fixed battery (for example, Redmi Note 10 Pro or Xiaomi 11T). When replacing the battery, inexperienced wizards can damage the plume speaker or contacts on the board.

⚠️ Warning: If the phone falls or gets caught in the rain, don't try to disassemble it yourself. corrosion on the board can spread and disable other components. Contact the service within 48 hours - this will increase the chances of successful repairs.

6. Hidden MIUI settings for sound

MIUI has hidden settings that can affect the sound of calls, and they're not found on the standard menu, but they're available through an engineering menu or special codes.

How to open the engineering menu:

1. Open the Phone app.
2. Enter the code ##4636##.
3. Go to the phone information section.
4. Scroll down to the Sound Settings block.

You can manually configure here:

• 🔢 Microphone reinforcement (helps if the other person can’t hear you).
• 🔊 Speaker balance (if the sound is distorted or too quiet).
• 📡 Network mode (sometimes switching to the WCDMA Only solves the problem of sound in calls).

Be careful: changing the settings in the engineering menu can cause malfunctions in the phone. If you are not sure, it is better not to touch these settings.

💡

On Qualcomm Snapdragon models (such as the POCO X3 Pro), you can include the VoLTE Enhancement option in the engineering menu, which improves the sound quality in 4G calls.

7. Alternative means of communication

If the sound problem in standard calls is not solved, use alternative communication methods. This is a temporary solution, but it will help you stay connected until the phone is fixed.

Best options:

• 📱 Messengers — WhatsApp, Telegram, Viber — support voice calls over the Internet, and sound quality is often better than mobile.
• 💻 IP-Telephony – apps like Zoiper or Linphone allow you to call over Wi-Fi using the Internet. SIP-account.
• 🎧 Bluetooth headset — if the speaker isn't working, plug in wireless headphones. Sound will go through them.

For enterprise users, Microsoft Teams or Zoom are good, they support calls to mobile and city numbers (paid). If you have a business fare from the operator, check if ViLTE (4G video calls) is enabled, which sometimes conflicts with standard calls.

8 When the operator is at fault

In rare cases, the problem with the sound in the calls lies on the side of the mobile operator.

• 📡 Coverage problems – in some regions, operators are shutting down 2G/3G, If your phone doesn’t support VoLTE, the calls won’t work.
• 🔄 Blocking services – if there is a negative balance or suspicion of fraud, the operator may limit outgoing calls.
• 🔧 Hardware failures – if the problem is massive, check for messages from the operator or sites like Downdetector.

How to check:

1. Call from another phone to your number – if the call does not pass, the operator has a problem.
2. Put it in. SIM-Card to another phone – if the calls are working there, it’s your Xiaomi fault.
3. Call in support of the operator (numbers: MTS - 0890, Beeline - 0611, MegaFon - 0500, Tele2 - 611).

If the operator has confirmed the problem on their side, you just have to wait for the fix, and usually these failures are fixed within a few hours.

⚠️ Note: On Xiaomi models with two support SIM-Cards (e.g. Redmi Note 11 Pro)+) Sometimes there's a conflict between slots. SIM, But they work on another one – try changing maps or updating your profile. SIM customized.
