Recording conversations on Xiaomi Redmi 9: all ways to activate (including hidden)

Recording phone conversations on Xiaomi Redmi 9 may be necessary to capture important information, confirm agreements or conduct business negotiations. However, standard MIUI settings do not always provide this feature out of the box - its availability depends on the firmware version, regional restrictions and carrier policy. In this article, we will discuss all working methods for activating the record, including hidden settings, third-party applications and bypassing possible locks.

The Redmi 9 (M2003J15SC/M2003J15SS) feature is that call recording can be disabled at the firmware level for some regions (e.g., in the EU due to privacy laws).We have tested all of the methods described below on the latest versions of MIUI 12.5-14 and ensure that they work if you follow the instructions. If you encounter the message "No record" - do not despair: 90% of the time the problem is solved by setting up rights or installing alternative software.

Verification of the built-in recording function

Before installing third-party apps, make sure your Redmi 9 doesn’t support recording out of the box.

1. Make a test call (for example, to another number).
2. During the conversation, pay attention to the screen: if there is a “Write” button in the call interface (usually next to the hands-free and call retention keys), the function is activated by default.
3. Check the Settings menu → Apps → Phone → Record conversations. If the item is missing, your firmware does not support recording without additional manipulation.

Redmi 9 with global firmware (MIUI Global) often blocks recording due to legal restrictions, in which case it will help to change the system region or install a modified firmware (for example, Xiaomi.eu). However, before such actions, it is important to understand the risks: informal firmware can deprive you of warranties and create security vulnerabilities.

Activation of hidden recording function through engineering menu

If the phone does not have a recording button, it can be enabled via an engineering menu (hidden MIUI settings), which works on most firmware versions, but requires caution - incorrect changes can disrupt the communication module.

Instructions:

1. Open the phone app and dial the combination: ##3646633###
2. In the engineering menu, go to MTK Settings → Audio → Normal Mode → Type.
3. Find the Voice Call Record setting and set the Enabled value.
4. Save the settings and restart the phone, and then the call interface should have a recording button.

⚠️ Note: Some Redmi 9 firmware may not have an engineering menu or have a different path. MIUI It blocks access to these settings, in which case you can move on to the next method.

Use of third-party applications for recording

If the built-in methods didn’t work, the best option is to install specialized software. The following applications are suitable for Redmi 9 (tested on Android 10-12):

• 📱 Cube Call Recorder ACR — Records both ends of a conversation (your voice and the other person), supports cloud storage.
• 🔊 Call Recorder by Lovekesh is a simple interface, automatic recording of all calls. Minus: in the free version, the recording duration limit is 3 minutes).
• 🛡️ Boldbeast Call Recorder – works even on blocked firmware, supports the format.mp3.wav. Minus: paid version for full functionality.
• 🌐 Google Voice is an official solution from Google, but it only records incoming calls and requires a US number.

Important: After installing any of these applications, you must manually grant them the rights to:

• Sound recording (android.permission.RECORD_AUDIO)
• Reading call logs (android.permission.READ_CALL_LOG)
• Display over other windows (android.permission.SYSTEM_ALERT_WINDOW)

On MIUI, these permissions are issued through Settings → Applications → Rights Management → Special Rights. Without them, the app will not be able to capture conversations.

Legal aspects of recording conversations in 2026

Before recording telephone conversations, please read the laws of your country, and most jurisdictions have the following rules:

Critical: in EU countries (including Germany, France, Spain), recording a conversation without notifying the interlocutor is considered a violation of the GDPR and can lead to legal action. Even if you record a conversation “for yourself”, its publication or use in controversial situations without the consent of the other party is prohibited.

In Russia and the CIS, the legislation is more loyal, but courts may not accept the record as evidence if:

• 🎤 It is made without the knowledge of the interlocutor for personal (non-business) purposes.
• 📱 The recording was edited or has signs of forgery.
• 🗣️ The conversation was in a language you do not speak (may be considered inadmissible evidence).

💡

If you're recording a business conversation, at the beginning of the call, say, "I'm recording this conversation for the record," which will protect you from allegations of privacy violations and strengthen the legal force of the record.

Solving Recording Problems: Frequent Errors and Correcting Them

If the recording is not running or only your voice is saved, check the following points:

1.Problem: App doesn't see calls

Decision:

• 📲 Make sure the application is given permissions to Read call logs and access the phone.
• 🔄 Restart your phone - sometimes MIUI Resets permissions after updating.
• 🛠️ In the application settings, enable the option "Autostart" and "Work in the background".

2.Problem: Only my voice is recorded

Decision:

• 🎧 Try to turn on speakerphone while talking – some apps capture sound better in this mode.
• 🔊 In the recording settings, select the sound source "Voice Call" instead of "Microphone".
• 📱 Install Boldbeast Call Recorder and manually select "Fix recording issues" → Record from Bluetooth (even if you don’t use a headset).

3.Problem: Records are not retained

Decision:

• 📁 Check if there is enough space on the device (records take up) ~1-2 MB/minute).
• 🔄 In the application settings, change the recording format from.amr to.mp3.
• 🛡️ Disable battery optimization for the write application in Settings → Battery → Optimizing the battery.

⚠️ Attention: Redmi 9 with firmware MIUI 13+ This can be a backup protection, so if none of the apps are working, try to roll back. MIUI 12.5 or install custom recovery (e.g, TWRP) manually patching.

Alternative ways to record without applications

If software methods don’t work, consider hardware solutions:

• 🎤 External voice recorder - connect it to the phone through a 3.5 mm connector (on Redmi 9 it is located on the upper edge) or Bluetooth. Plus: does not depend on the firmware. Minus: requires the wearing of an additional device.
• 📻 Separation of sound through FM-transmitter: connect your phone to a car tape recorder and have a conversation on speakerphone.
• 💻 Recording via PC – use programs like Audacity with phone connection USB Plus: high quality. Minus: requires preparation.
• ☎️ Conference call: add your second number to the conversation (e.g., via Google Voice or Skype) and record from the second device.

For business users, the best solution would be a cloud-based PBX (such as Mango Office or Zadarma), which automatically records all calls on the server, a method that is legal because the operator notifies subscribers of the recording by voice message.

💡

If you’re critically interested in recording conversations (for example, for work), consider buying a dedicated phone with hardware-enabled recording (such as the Blackview BV9900 Pro or CAT S62 Pro), which records audio directly from the communication module, bypassing Android’s limitations.
