How to set up a microphone on Xiaomi Redmi Note 10 Pro: from basic parameters to fine optimization

Xiaomi Redmi Note 10 Pro is one of the most popular mid-range smartphones, but even its owners sometimes face problems with the microphone: a quiet voice in calls, noise during recording or complete lack of sound. The reasons can be in both software settings and hardware malfunctions. In this article, we will analyze all the ways of setting up the microphone, from basic parameters in the phone menu to hidden engineering modes and equipment diagnostics.

The Redmi Note 10 Pro features three microphones: the main one (bottom of the device), the noise suppressor (top) and the additional one for active noise cancellation (ANC). Their work together provides clean sound in calls and recording, but requires proper calibration. If you notice that the interlocutor does not hear you well or the recording is accompanied by extraneous noises, do not rush to carry the phone to the service, in 80% of cases the problem can be solved by yourself.

1. Check the basic microphone settings in MIUI

Before you dig deeper, make sure that the problem isn’t with the settings disabled or the apps conflicting, starting by checking the microphone permissions for key services:

  1. Open Settings β†’ Applications β†’ Permissions β†’ Microphone.
  2. Make sure that the Phone, Recorder and instant messengers (WhatsApp, Telegram) are allowed access.
  3. If the application is not in the list, run it and grant permission when requested.

Check the call settings further:

  • πŸ“ž Go to Settings. β†’ SIM-maps and mobile networks β†’ Call settings.
  • πŸ”Š Activate Voice Improvement option (if available in your version) MIUI).
  • 🎧 If you use a headset, select Bluetooth Priority for wireless headphones.

After the update MIUI lost sound in calls, try resetting the network settings: β†’ SIM-map β†’ Network resets. This often solves problems with routing audio streams.

Also worth checking is Do Not Disturb mode, which sometimes locks the microphone to save charge, open the notification panel and make sure the mode is turned off or configured to resolve calls.

2. Diagnostics of hardware problems of the microphone

If the software settings didn't help, there may be a problem with the microphones being physically damaged or contaminated.Redmi Note 10 Pro has three microphones:

To check the availability:

  1. Use a built-in voice recorder (Tools β†’ voice recorder) and record your voice from different distances (5 cm, 30 cm, 1 m).
  2. Call another phone and check the sound quality in the speaker and headset.
  3. Examine the microphones for dust, moisture, or mechanical damage, often just cleaning the holes with a soft brush.
How to check the microphone through the Engineering Menu?
Type in the Phone app code ##4636##, select Phone Information β†’ Microphone. This shows the signal strength in decibels (dB). Normal values: 40-60 dB when talking 10 cm from the microphone. If the level is below 30 dB, the microphone is faulty or software disabled.
