Recording phone conversations on Xiaomi Redmi 8 may be necessary to save important details of business conversations, legal advice or just personal conversations. However, standard MIUI settings do not always provide this feature out of the box - it depends on the firmware version, region and operator policy. In this article, we will discuss all the current ways to enable auto recording, from hidden system settings to third-party applications, and also explain how to circumvent possible restrictions.
It is important to understand that the legislation of many countries (including Russia) requires notifying the interlocutor about the recording of the conversation. On Redmi 8 with MIUI 12/13/14 firmware, the recording function can be blocked at the kernel level - in this case, additional manipulations will be required. If you encounter the message "No record is possible" or simply do not see the option on the menu, do not despair: below you will find solutions for any situation.
Checking the support of auto-recording in the standard application โPhoneโ
First, check if the recording feature is available in Xiaomiโs native Phone app. On some versions of MIUI (especially for India, Europe, and global firmware), the option is hidden, but it can be activated via an engineering menu or settings.
Open the Phone app, click on the three dots in the top right corner, and select Settings. Scroll down to Record Conversations. If you don't have a point, your firmware doesn't support out-of-the-box, so move on to the following ways.
- ๐ฑ Global firmware (MIUI Global: Recording is usually disabled for legal reasons.
- ๐ฎ๐ณ Indian firmware (MIUI India: The feature may be available but with the interlocutorโs notification.
- ๐จ๐ณ Chinese firmware (MIUI China: Recording is often free of restrictions.
- โ๏ธ PixelExperience (LineageOS): Requires manual adjustment.
If you see Auto Record but it's inactive, try updating the Phone app through Google Play or MIUI App Store.
Enabling recording through the engineering menu (hidden method)
Some versions of Redmi 8 have a recording feature hidden in the engineering menu, which works on MIUI 11-14 firmware, but requires caution that incorrect settings can disrupt the phone.
To open the engineering menu, enter the phone combination in the application:
##4636##Next, go to Phone Information and scroll down to Record Settings (or Call Recording) if you have an option, activate it and restart the device.
โ ๏ธ Warning: Do not change other options in the engineering menu unless you are sure of their purpose.This can lead to failures in the communication module or complete loss of the network.
If #4636### does not work, try the alternative code.
##847##It opens the GSM testing menu, where additional recording settings are sometimes hidden.

Use of third-party applications for auto-recording
If the standard methods don't work, third-party apps will come to the rescue.
- ๐ค Cube Call Recorder ACR โ Supports automatic recording, cloud storage and encryption.
- ๐ผ Call Recorder โ Automatic Call Recorder โ Simple interface, Google Drive integration.
- ๐ Truecaller โ in addition to the number determinant, has a built-in record (requires a premium subscription).
- ๐ฑ MIUI Call Recorder Enabler โ activates the hidden recording function in a standard application (does not work on all firmware).
Before installing, check the permissions of the application: it must request access to the Microphone, Phone and Warehouse. Some programs (such as Cube ACR) require additional configuration in Special Options for correct operation.
Instructions for Cube Call Recorder ACR:
- Download the app from Google Play.
- When you first start, provide all the permissions requested.
- Go to Settings โ Record and turn on Auto Record.
- Select the save format (MP3 or WAV) and the folder to store files.
โ ๏ธ Note: Some banking apps and instant messengers (such as SberBank Online or WhatsApp) block recordings of conversations for security reasons, in which case you will have to use a second phone or an external recorder.

Set up auto-recording via ADB (for advanced users)
If you're ready to experiment, you can turn on the recording via ADB (Android Debug Bridge), a technique that requires connecting the phone to a computer and basic command line knowledge, but gives you access to hidden MIUI functions.
Steps for activation:
- Enable USB Debugging in the Developer Settings โ About Phone โ MIUI Version โ Press 7 times, then go back to Additional Settings โ For Developers.
- Connect Redmi 8 to your PC and open the terminal (or Command Prompt on Windows).
- Enter the command to check the connection: Adb devices should appear the name of your device.
- Execute the command to enable the record: adb shell settings put global call_recording_support 1
- Reboot the phone.
After the reboot, the Phone app should have Recorded Conversations. If it's not available, try an alternative command:
adb shell am start -n com.android.server.telecom/.settings.CallRecordingSettingsActivity| ADB Team Team | Appointment | Note |
|---|---|---|
| adb shell settings put global call_recording_support 1 | Includes system-level recording support | Works at MIUI 12-14 |
| adb shell pm grant com.miui.voiceassist android.permission.RECORD_AUDIO | Gives permission to write for the system application | It may be necessary for some scaling |
| adb shell am broadcast -a android.intent.action.CALL_RECORDING_STATE_CHANGED --ez state true | Forcedly activates the recording | Temporary solution reset after rebooting |
On the firmware MIUI 14 newer call_recording_support can be blocked - in this case, only the firmware with the unlocked bootloader will help.
Solving Recording Problems: Frequent Errors and Correcting Them
Even after a successful setup, the auto record may not work, and letโs look at the typical problems and ways to fix them:
- ๐ ยซRecording is impossible" when calling - check if your operator blocks the record (for example, MTS or Beeline at some rates). SIM-card.
- ๐ต No audio in the recording - make sure the app is given permission to access the microphone. Also check if the Do Not Disturb mode is activated.
- ๐ Recording is terminated in 5-10 seconds, which is a restriction on some firmware, and only a change of software or the use of an external recorder will help.
- ๐ Files are not saved โ check the free space on the device and the applicationโs rights to write in storage.
If the recording works, but the quality leaves much to be desired, try:
- Turn off noise reduction in the microphone settings.
- Use a wired headset with a microphone (improves voice capture).
- Switch to WAV instead of MP3 (quality is better, but more weight is the file).

Legal aspects of recording conversations in 2026
Before you turn on the auto record, read the norms of your country. In Russia, according to Art. 138 of the Criminal Code of the Russian Federation and the Federal Law "On Communications", recording a conversation without the consent of the interlocutor is allowed only in cases:
- ๐ If you are a participant in the conversation (but you cannot distribute the recording without consent).
- โ๏ธ If the recording is made in self-defense (e.g. threats or blackmail).
- ๐ผ If the interlocutor is notified of the recording (for example, the autoinformer at the beginning of the call).
The EU has a GDPR that requires explicit consent to the processing of personal data, including voice recording, and a violation can result in a fine of up to 20 million euros, or 4% of the companyโs annual turnover.
To avoid problems:
- Always notify the person about the recording (e.g., โThe conversation is being recorded to record the information. Do you mind?โ).
- Do not keep records for longer than necessary.
- Do not distribute the recordings without the consent of the participants.
โ ๏ธ Note: In some countries (e.g. Germany, France), even storing a record without consent is considered illegal.
