Echoes in Xiaomi phone when talking: causes and ways to eliminate

Do you talk on a Xiaomi phone and the person complains that you hear an echo? Or do you experience an unpleasant repetition of your voice in the dynamics? This problem is familiar to many owners of Redmi, Poco and Mi smartphones — especially after MIUI updates or when using a headset. In 80% of cases, the echoes are due to software failures, but sometimes hardware malfunctions are to blame.

In this article, we will discuss 7 proven ways to remove echoes in a Xiaomi phone, from basic audio settings to deep microphone diagnostics. You will learn how to distinguish a software problem from a breakdown, which models are more likely to suffer from echoes (Redmi Note 10 Pro, Poco X3 Pro, Mi 11 Lite), and what to do if standard methods do not help. All instructions are relevant for MIUI 14/15 and HyperOS.

Before you start setting up, check if you or the person you're talking to is echoing, if it's a two-way problem, it's probably the microphone or the firmware, if you're the only one who can hear the echo, maybe it's the dynamics or the network delays, and that will help narrow the search for a solution.

1. Checking basic sound settings

Start with the obvious: sometimes echoes are caused by a misconfigured conversation mode or sound effects on. Xiaomi has hidden parameters that can affect voice transmission.

Open Settings → Sound and vibration and do the following:

• 🔇 Turn off Voice Improvement, which often distorts the sound in the microphone. Located in Settings → Special Features → Voice Improvement.
• 🎧 Check the headset mode: If the echo only appears when you connect the headphones, try turning off the "Use the headset microphone" option in Bluetooth settings.
• 📞 Reset your call settings: to Settings → Apps → Phone → Storage → Reset settings.

Pay special attention to the item "Conversation Mode" (in some firmware it is hidden) to find it:

1. Enter the dialer code: ##4636##
2. Select "Phone Information"
3. Scroll down to "Sound Settings" and set "Modem" → GSM (even if you have 4G).

💡

If the echo is gone after resetting the call settings, but comes back after a few days, the problem is in the cache of the Phone app. Clean it once a week in Settings → Apps → Phone → Storage → Clear the cache.

Microphone Diagnostics: Hardware or Software Problem?

The echoes of a conversation can be caused by a faulty microphone, poor contact on the plume, or a clogging hole.

Run the built-in Diagnostics app (or Equipment Test in older versions of MIUI):

1. Enter ##6484## (for new models) or #4636## → “Equipment test”.
2. Select Microphone and record a test message.
3. If the sound is intermittent or absent, the microphone is faulty.

Also, check the phone visually:

• 🔍 Check the microphone hole (usually next to the charging connector) for dust or moisture.
• 🛠️ Carefully tap on the bottom of the body — if the echo is gone, the problem is poor plume contact.
• 🎤 Connect an external microphone (e.g. from a headset) - if the echo has disappeared, the built-in microphone is to blame.

3. Reset network and sound settings

If the echo appears after the MIUI update or the SIM- card change, the problem may be a conflict of network settings. Resetting network settings often helps eliminate voice delays, which create an echo effect.

Follow the following steps:

1. Go to Settings. → SIM-maps and mobile networks.
2. Select your SIM- card and click “Reset Network Settings”.
3. Confirm the action and restart the phone.

After the reboot:

• 📶 Manually select the operator (do not leave "Automatically").
• 🔄 Turn on/off "Only" mode 3G" (sometimes) 4G/VoLTE creates delays).
• 🔕 Turn off VoWiFi (Wi-Fi calls) in the SIM- card settings.

If the echo is associated with sound settings, reset:

1. Open Settings → System and device → Resetting settings.
2. Select "Resetting Sound Settings" (not to be confused with a full reset!).

4. Update firmware and rollback to stable version

Over 40% of echoes in Xiaomi are caused by MIUI/HyperOS firmware bugs, especially in beta versions. If the problem occurs after the update, try:

Option 1: Upgrade to the latest stable version

1. Go to Settings → About the phone → System update.
2. Click on the three dots in the upper right corner and select "Download the latest version".
3. If the update doesn’t help, check for “Region Updates” (sometimes global firmware contains bugs).

Option 2: Reverse to the previous version of MIUI

If the echo appears after the update (for example, from MIUI 13 to MIUI 14), you can return the old firmware.

• 📥 Download the archive with the desired version from the official Xiaomi website (choose Stable, not Beta).
• 🔧 Rename the file to update.zip and place it in the root of the phone's memory.
• 🔄 Go to Settings. → The phone. → Updating the system → Three points. → Select a firmware file.

💡

Before rolling back the firmware, back up your data! Use Settings → Additional → Backup and Reset → Local Backup. Recoilout can result in loss of photos and messages.

For models Poco F4 GT and Redmi K50 known bug with echoes in the firmware MIUI 14.0.3.0 and 14.0.4.0. Solution - upgrade to 14.0.6.0 or higher.

5.Setting up Bluetooth codecs and headset

Echoes when using a Bluetooth headset or wired headphones are a separate story.

• 🎵 Incompatible audio codecs (e.g., aptX or LDAC).
• 🔋 Low headset charge (less than 20%).
• 📡 Interference from other Bluetooth devices.

To eliminate echoes in the headset:

1. Open Settings → Connected devices → Bluetooth settings.
2. Find your headset and click on the gear next to its name.
3. Turn off the options "High Quality Audio" and "Absolute Volume".
4. In the "Code" section, select SBC (the most stable, although not the highest quality).

For owners of Xiaomi Buds or Redmi AirDots:

• 🔄 Reset your headphones to factory settings (press the button for 10 seconds before flashing red/white).
• 📱 Remove the device from the Bluetooth pairing list and reconnect.
• 🔋 Charge the headphones to 100% – when low charge, they automatically switch to energy-saving mode, which can create delays.

Hardware solutions: cleaning, repair, replacement

If the software methods didn't work, the problem is probably the hardware, and here's what you can do yourself (and when to contact the service):

Self-acting:

• 🧹 Clean the microphone: Use a toothpick (carefully!) or a spray of compressed air to remove dust from the hole. Don't use wet wipes!
• 🔧 Train check: If the phone fell, the microphone plume could have moved away. You have to take the phone apart (experience required).
• 🔋 Replacement of microphone: Part costs between 300 and 1000 rubles depending on the model. Redmi Note 12 Pro+ often requires replacement of the entire bottom module.

When to contact the service:

• 🚨 Echoes are accompanied by extraneous noises (cracking, hissing) — a sign of damage to the motherboard.
• 💧 The phone got into the water, and even after drying, the contacts could oxidize.
• 🔌 The problem occurred after the battery or display was replaced, which could have damaged the microphone plume.

💡

Before visiting the service, check if your phone is not covered by the warranty. For this, enter the IMEI on the Xiaomi website. If the warranty is active, the microphone repair will be free (provided that the problem is not your fault).

7. Alternative solutions: messengers and third-party applications

If the echo is only haunting you in certain apps (like WhatsApp or Zoom), the problem may be their settings.

For WhatsApp/Viber/Telegram:

• 🔄 Reinstall the app (pre-save chats).
• 🎤 In the application settings, turn off "Use VoIP for calls" (if any).
• 📵 Switch from Wi-Fi to mobile internet (or vice versa) during a call.

For Zoom/Google Meet:

• 🎧 In the audio settings, select "Use phone sound" instead of "Bluetooth".
• 🔇 Turn off "Automatic Volume Control."
• 🔗 Use a wired headset instead of Bluetooth.

If the echo appears in only one app, try using alternatives:

• 📞 Instead of the standard "Phone" install Google Phone (available in the Play Market).
• 💬 For instant messengers, try Signal or Skype — they’re better optimized for Xiaomi.

💡

Third-party calling apps (like Google Phone) are often better optimized for Xiaomi microphones than standard software, which is because Xiaomi modifies Android and Google uses pure AOSP.
