The microphone in a Xiaomi smartphone is like the nervous system for voice calls, recordings and working with voice assistants. When it suddenly ceases to function, the device loses half of its functionality: you can not call, use Google Assistant or record a voice message. But don't panic: 80% of the time the problem is solved software, without going to the service center.
In this article, weβll break down all the possible reasons why Xiaomiβs microphone is on the market (including the Redmi Note 12, Poco, and other models). X5, Mi 11 Lite and others may not work, from the usual contamination of the connector to the failures in the firmware, you will receive step-by-step instructions with illustrations (in text format), checklists for diagnostics and tips on how to avoid repeated breakages. MIUI, These are often the source of problems.
If your smartphone is in the water, dropped or mechanically impacted, go to the hardware malfunction section. In all other cases, start with software diagnostics: this will save time and money.
1. Quick check: Does the microphone work at all?
Before digging deeper, make sure the problem is really in the microphone, not in a particular app or settings.Do the test in 3 stages:
- Call a friend or your second number, and if the other person can't hear you, the problem is confirmed.
- Voice input. Open Google Search or Google Assistant and try to say something. If the text doesn't recognize, the microphone doesn't transmit the signal.
- Voice recording. Use the standard voice recorder app (or MIUI voice recording) if the silence or interference is a hardware or system problem.
β οΈ Note: Some Xiaomi models (e.g. Redmi) 9A POCO M3) It can be a separate microphone for calls and a separate microphone for recordings. If the calls don't work, but the recorder records, read the section on call settings.
If the microphone doesnβt work in just one app (like WhatsApp or Telegram), the problem lies in the settings of that app.
MIUI settings: What could turn off the microphone?
MIUI is known for its abundance of hidden settings that can accidentally (or unknowingly) turn off the microphone.
- π Do not disturb mode. Go to Settings β Sound and vibration β Don't disturb. Make sure that the mode is not activated Only alarm clocks or All sounds are off - they can block the microphone for calls.
- π€ Permissions for microphone. β Annexes β Permits β Microphone check if access is enabled for system applications (Phone, Camera, Google).
- π Resetting the sound settings. β System and device β Resetting settings β You can reset the sound settings to the factory parameters without losing data.
- π± User profile: If you use the Guest Mode or the Work Profile, there may be restrictions on microphone use.
π‘ Hidden chip MIUI: On some models (e.g. Xiaomi) 12T) There's a separate setting called Voice Improvement in Call Settings. If it's on but the microphone is weak, try turning it off and restarting the phone.
βοΈ Checking settings MIUI
If after all the manipulations the microphone did not work, move to the next section - perhaps the fault of the firmware or application conflict.
3. Application conflicts and system failures
Often the microphone stops working after installing a new app, updating MIUI, or even a banal failure in the background.
- π± Safe Mode. Press the power button, then hold your finger on Turn off until Safe Mode appears. This mode only runs system applications. If the microphone is running, it's third-party software.
- π Cache cleanup. Go to Settings. β Annexes β Manage apps, find Phone, Camera and Google, then click Clear cache.
- π« Call blacklist. MIUI There's a number lock feature that sometimes fails. β Settings β Number locking.
- π οΈ Reset application settings. In Settings β System and device β Resetting settings β Reset application settings can be returned factory permissions without deleting data.
β οΈ Note: If the problem has occurred after the update MIUI, Don't rush to roll back to the old version. First, try to clear the system update application data (in the Settings menu). β This often helps with failures after an update.
| Symptoms. | Probable cause | Decision |
|---|---|---|
| The microphone works in a voice recorder, but not in calls. | Failure in the Phone app | Clear cache and phone data, reboot the device |
| The microphone only works in headphones. | Main microphone contamination or failure to switch audio routes | Clean the connector, check the settings of the Sound β Audio effects |
| Noise/interference during conversation | Conflict with an app to record calls or improve sound | Remove third-party calling apps, disable voice enhancement |
| The microphone does not work in a specific application (WhatsApp, Telegram) | Lack of permissions or failure in the application itself | Reinstall the application, check permissions in Settings β Applications |
If the microphone is still silent after all the manipulations, it may be the firmware's fault, and in the next section we'll tell you how to check and fix it.
4. Failures of firmware and MIUI updates
MIUI firmware is not only an interface, but also a core system responsible for the operation of hardware components, including the microphone. If the problem arose after an update or "independent" firmware experiments, here's what to do:
- π Verification of the version MIUI. Go to Settings. β The phone. β Version. MIUI. If the version is stable, but the microphone doesn't work, it's probably a known bug, 4PDA Xiaomi Community for complaints from other users.
- π If the problem appears after the update, you can try to roll back. To do this, download the previous version of the firmware from the official Xiaomi website and install it through the System Update. β Three points. β Select a firmware file.
- π οΈ Reset to factory settings. Extreme measure, but sometimes necessary. Important: pre-backup to Settings. β Additionally. β Backup and reset.
- π§ Fastboot flashing, if the reset didn't help, it might have damaged the system area, and you'll need a computer, Mi Flash Tool, and the official firmware for your model.
β οΈ Warning: Fastboot flashing runs the risk of turning your phone into a brick if you choose the wrong firmware version. Always check the compatibility of the model (Redmi Note) 11 β Redmi Note 11 Pro) and the region (Global/EU/China).
How to find out the exact model Xiaomi for firmware?
If you're not sure about your abilities, you'd better go to a service center, but before you do, check for hardware reasons, and it might be easier than it sounds.
5. Hardware malfunctions: when without repairs can not do
If all the software methods have been tried and the microphone is still down, it's time to look at the physical breakdowns.
- π¦ Even if the phone is not sinking, condensation or high humidity can oxidize the microphone contacts. Check the moisture indicator (usually a red dot under the tray). SIM-map).
- π Pollution of the connector: Dust, pile or debris in the headphone jack (or USB-C) They can block the microphone. Clean the connector with a soft toothbrush or compressed air.
- π± The plume's been damaged, and the plume that connects the microphone to the motherboard could have been removed after a fall or impact.
- π Microphones have a limited lifespan (especially in low-end models like the Redmi). 9C). They will eventually wear out or break down.
- π Battery problems: A bloated battery can push the motherboard, causing the microphone to malfunction.
π‘ How do you check for hardware malfunction? Connect wired headphones to a microphone. If they have a microphone that works and the phone doesn't, the hardware is the problem.
π‘
If the phone falls or gets wet, don't turn it on right away! Let it dry for at least 24 hours in a dry place (such as rice or silica gel).
β οΈ Warning: If you suspect a hardware breakdown, donβt try to disassemble the phone yourself (especially adhesive models like the Xiaomi 13).This could result in loss of warranty or additional damage.
6. Specific problems with calls
Sometimes the microphone works in recordings and voice assistants, but refuses to transmit voice during calls. This is a MIUI problem, and here's how to solve it:
- π Call settings. Go to the phone. β Settings β Call settings and check out:
- π Resetting your phone. In Settings. β Annexes β Phone. β Warehouse β Clear the data, reset the app settings. Attention: this will delete the call history!
- πΆ Operator problems: Sometimes, a failure in the operator's network (e.g., when switching to VoLTE) can block the microphone:
π‘ Hidden setting: Some Xiaomi models (e.g. Mi 11 Ultra) have a separate Bluetooth audio switch in call settings. If it's on but Bluetooth is off, the microphone may not work. Check this setting!
π‘
If the microphone doesnβt work only in calls, but voice recording works, the problem is solved 90% of the time by resetting the phone app settings or turning off VoLTE.
7.How to Prevent Mikrone Problems in the Future
To make the microphone on your Xiaomi lasts a long time and does not fail at a critical moment, follow these recommendations:
- π‘οΈ Use a microphone-protected cover. The microphone holes (usually at the bottom of the phone) are easily clogged with dust.
- πΏ Avoid moisture, even if your Xiaomi has protection. IP53 (Like the Redmi Note 12, that doesn't mean it's waterproof. Don't use your phone in the rain or in the bathroom.
- π Update regularly MIUI. Newer versions of firmware often fix microphone-related bugs, but check the forum reviews before updating!
- π΅ Do not drop the phone. Hitting the bottom of the case (where the microphone is located) most often disables it.
- π Do not use your phone at maximum volume, which can damage speakers and microphones due to overload.
- π οΈ Clean the connectors. Clean the headphone jack once a month. USB-C dust-and-foil.
β οΈ Attention: If you use voice assistants often (Alice, Google Assistant), they can overload the microphone, reducing its lifespan.
By following these tips, you minimize the risk of a microphone breakdown, but if a problem has already occurred, you now know how to diagnose and fix it!
