Recording phone conversations on Xiaomi Redmi 9 may be necessary for recording important information, evidence in a dispute or just for convenience. However, standard MIUI capabilities in this model are limited — unlike the flagship devices of the brand, where the function of recording calls is often built out of the box. In this article, we will analyze all the current ways of recording conversations, including hidden system settings, third-party applications and workarounds for Redmi 9 (codenamed lancelot).

It is important to consider that the legislation of many countries (including Russia) requires notifying the interlocutor of the recording of the conversation. We do not recommend using the recorded files in court or for blackmail - this can entail legal liability. MIUI 12.5–14 (Android 10–12) and relevant to Redmi 9/9A/9C/9T.

The built-in MIUI call recording feature: why it's not on Redmi 9

Xiaomi owners often face a paradox: on flagships like the Mi 11 or Redmi Note 10 Pro, call recording is available by default, but on budget models (including Redmi 9), it is not.

• 🌍 In India and some Asian countries, the recording feature is enabled by default due to local laws.
• 📱 In European and Russian firmware (EEA/RU ROM) It is disabled at the request of Google (Privacy Policy).
• 🔧 On Chinese firmware (CN ROM) The function is there, but its work depends on the version. MIUI.

Check your firmware can be in the Settings menu → About phone → MIUI version. If there is RU or EEA at the end of the name, there is no built-in entry. You can only circumvent this restriction through changing the region (risky) or installing custom firmware (requires unlocking the bootloader).

⚠️ Warning: Change region to Redmi 9 via Settings → Additionally. → The region can lead to loss of warranty and problems with the OTA-Xiaomi blocks such manipulations at the server level.

2. Method 1: Applications for recording calls from Google Play

The easiest and safest method is to use specialized applications, and we tested 10 popular solutions and selected the 3 most reliable ones for Redmi 9:

To customize the recording via Cube Call Recorder ACR (recommended as the most stable):

1. Download the app from Google Play.
2. When you first start, grant permissions to Record audio, Contacts and Phone.
3. In the settings, select the write format (MP3 or WAV) and the folder to save (preferably specify /SDCard/CallRecords).
4. Activate Automatic Record for all calls or only for selected contacts.

⚠️ Attention: Redmi 9 with Android 11+ applications are prohibited from recording sound from the microphone during a call through a standard API. The solution is to use an alternative audio source (the Cube has a setup). ACR It's called Record via Speaker, and it's going to be recorded through a speaker, which is slightly degraded.

Method 2: Activate the hidden recording function via ADB

For advanced users, there is a way to enable root-free call recording via Android Debug Bridge (ADB), which works on MIUI 12.5-14, but requires the phone to be connected to a PC.

Step-by-step:

1. Enable Developer Mode on Redmi 9: Settings → About Phone → MIUI Version (click 7 times)
2. Activate USB Debugging in Settings → Additional → For developers.
3. Connect the phone to the PC and execute the command to ADB: adb shell settings put global force_call_recorder_enabled 1
4. Restart the device. After that, a write button will appear in the call interface (if the firmware supports the function).

On some versions of MIUI for Redmi 9, this method only works after an additional command is given:

adb shell am start -n com.android.incallui/.InCallActivity

If the write button does not appear, then your firmware does not contain the corresponding system files, in this case, only installing custom firmware (for example, Xiaomi.EU), where the write function is enabled by default, will help.

4. Method 3: Recording via a second SIM card or other phone

If the software methods are not suitable, you can use hardware bypass:

• 📞 Double. SIM: Put a second SIM card in Redmi 9 and call it from the main number.
• 🎧 Headphones with microphone: Connect wired headphones (such as Xiaomi Hybrid) and use a voice recorder to record sound from a microphone.
• 📱 Second phone: Put a second smartphone with the recorder on next to it (for example, Redmi Note 8 Pro has a good microphone).

The advantage of this method is 100% legality (you do not interfere with system files) and no dependencies on the version of MIUI.

• The quality of the recording depends on the acoustics of the room.
• The interviewer may hear an echo if the microphone of the second device is too close.
• Additional equipment is required.

💡

For better sound when recording via a second phone, use Sony’s Voice Recorder app – it has noise cancellation and microphone sensitivity adjustment.

5. Method 4: Cloud services and recording via IP-telephony

If you make frequent calls via VoIP (WhatsApp, Telegram, Skype), you can record conversations directly in these apps:

• 💬 WhatsApp: Enable Call Recording in the App Settings (available in the Business Version).
• ☁️ Google Voice: Automatically saves your call history (available only for U.S./Canada numbers).
• 📞 Skype: Press... → Start recording during the conversation (notifies the interlocutor).

For regular mobile calls, CallNote (formerly TapeACall) is suitable:

1. Install the application and register.
2. During the call, click Add Record - the system will transfer the conversation to a conference call with the recording server.
3. After the call is completed, the file will be saved to the cloud (available for 7 days in the free version).

The downside of cloud services is the latency of sound (1-2 seconds) and the need for an Internet connection, plus the recordings are stored on the server and do not take up space on the phone.
