Recording conversations on Xiaomi Poco M3: all ways and hidden chips MIUI

Xiaomi Poco M3 is a popular smartphone with MIUI firmware, which doesn’t always offer obvious features out of the box, one of which is recording phone conversations. Unlike flagship models, where the option can be available by default, on budget devices it often has to be activated manually or through workarounds.

In this article, we will discuss all working methods for enabling the recording of calls on Poco M3 (including versions with MIUI 12/13/14), discuss the legal aspects of using the feature in Russia and CIS countries, and consider alternative applications for those who do not have standard tools, and pay special attention to the hidden mode of recording through the engineering menu, which works even on blocked firmware.

Why is there no default call record button on the Poco M3?

The lack of a visible recording option in the call interface is not a mistake, but a conscious decision by Xiaomi.

• 📜 Legal restrictions: In some countries (e.g. the EU), recording conversations without consent is prohibited. Xiaomi simplifies software localization by hiding the function in heavily regulated markets.
• 🔄 Versions MIUI: On Poco. M3 firmware-based (MIUI Global option can be disabled, while in Chinese (MIUI China) or Indian (MIUI India version it's available.
• 📱 Hardware constraints: Budget models are sometimes stripped of "extra" features to save resources, such as high-quality recording requiring additional audio processing.

Importantly, even if the button is not in the interface, hardware support for recording on the Poco M3 is always present. It should be simply "unlocked." This is discussed in the following sections.

Method 1: Enable via hidden MIUI settings (without root)

The most reliable method is to activate the function through the engineering menu, which works on most versions of MIUI and does not require superuser rights.

1. Open the phone app and dial the combination: ##6484##
2. The MTK Engineer Mode menu will appear (if the combination doesn't work, try ##3646633##).
3. Go to Hardware Testing → Audio → Normal Mode.
4. Find Type and select Sph (Write Microphone).
5. Return to Audio and activate Voice Call Record (switch to Enable).
6. Reboot your smartphone.

After the reboot, a recording button will appear in the call interface (usually in the form of a dot circle or microphone). If it is not, check the settings of the Phone application:

Settings → Applications → Phone → Rights → Allow recording of sound |

Settings → System → Permissions → Microphone (for the “Phone” application) |

Restart the Phone application through Task Manager |

Update MIUI Up to the latest version (through Settings) → The phone. → Updating the system)-->

Attention! Some Poco M3 firmware may not have an engineering menu or be blocked, in which case try alternative methods in the following sections.

Method 2: Use of the built-in MIUI recorder (if available)

On some versions of MIUI 12.5+ for Poco M3, the call recording function is hidden in the Phone app settings.

1. Open the phone and tap three points (⋮) top-right.
2. Select Settings → Recording of conversations.
3. Activate the Write Automatically or Record Manually.
4. Specify which calls to record: All, outgoing or incoming only.

If you don't have a Record conversation on the menu, your firmware doesn't support it, and it's going to help:

• 🔄 Update MIUI Up to the latest version (through Settings) → The phone. → Updating the system).
• 📥 Install an alternative call app (such as Google Phone) that supports recording.
• 🛠️ Manual editing of system files (requires root).

1. Go to Settings → Applications → Application Management → Phone.

2. Press Warehouse → Clear the cache.

3. Restart the application.

This often helps when changes don’t apply due to cacheted data.-->

Method 3: Third-party applications for recording calls

If the built-in methods didn't work, Google Play apps will come to the rescue, and we tested the top-end solutions on the Poco M3 and ranked them for reliability and quality of recording:

When installing third-party recorders:

⚠️ Attention: Call recording apps require permission to access the microphone, contacts and call log. Do not install programs from unknown developers - they can share your conversations with third parties!

For maximum reliability, we recommend:

1. Before installation, turn off the Internet (so that the application does not send data).
2. Use Local Storage instead of cloud services.
3. Regularly clean your record history through the App Settings → Delete everything.

Method 4: Write via Google Drive (alternative method)

If you want a one-time recording of an important conversation, and you don't want to install additional programs, you can use Google Drive, which works through the Voice Recording function:

1. Open Google Drive and click + → Record Voice.
2. Start recording before the call starts (so you don’t miss the start of the call).
3. Turn on speakerphone on the Poco M3 so the microphone picks up sound from both sides.
4. At the end of the conversation, save the record in My files → Audio.

Cons of the method:

• 🔇 Low quality of sound (noise, echoes due to hands-free communication).
• 🕒 You can’t record a conversation in secret (the interviewee will hear an echo).
• 📱 You need to keep your phone next to the speaker.

But the pros are obvious:

• ✅ No need to install additional programs.
• ✅ Recording is saved directly to the cloud (does not take up space on the phone).
• ✅ It works even on blocked firmware.

💡

Google Drive is the only way to record calls to Poco M3 without installing third-party apps, but is only suitable for hands-free conversations.

Legal aspects of recording conversations in Russia and the CIS

Before using call recording, it is important to understand the legal implications.

Key rules for Russia:

• 📜 Recording a conversation without notifying the interlocutor does not violate the law if it is conducted for personal purposes (Article 137 of the Criminal Code of the Russian Federation).
• 🚨 Using a recording in court or public dispute requires proof that it is not edited.
• 🎤 Recording conversations on a work phone (if issued by a company) may be considered a breach of an employment contract.

⚠️ Note: If you record a conversation for the purpose of blackmail, dissemination of personal information or commercial use (for example, for the sale of a database), this qualifies as a violation of Art. 138.1 of the Criminal Code of the Russian Federation (“Illegal trafficking in special technical means”). Maximum penalty - up to 4 years in prison.

Frequent problems and their solutions

Even after successfully activating a Poco M3 record, users are faced with errors.

Problem 1: Recording is retained but not reproduced

Causes and solutions:

• 🔊 Damaged audio file: Try playing the recording on another device. If it doesn't work, delete and re-record the conversation.
• 📁 Incorrect format: Some recorders save files to.amr or.awb that not all players support. VLC or convert into MP3 via Online-Convert.
• 🛠️ Codec error: Update Poco firmware M3 last-minute MIUI.

Problem 2: Recording is terminated in 1-2 minutes

This is a typical mistake of record-breaking applications that save battery life.

• ⚡ Turn off battery optimization for the recording app: Settings → Battery → Optimizing the battery → Select an application → No restrictions.
• 📵 Check if the recording is blocked by the energy saving mode.
• 🔄 Reinstall the recorder app (sometimes resetting its settings helps).

Problem 3: The interviewee hears an echo or noise

It's because of:

• 🔈 Microphone Conflict: Disable all other apps that use the microphone (e.g. Shazam or Google Assistant).
• 📶 Bad Network Signal: Switch to 4G Wi-Fi Calling (if supported by the operator).
• 🎧 Headphone usage: Recording through Bluetooth headphones often causes interference. Connect wired ones.
