Modern smartphones running on the Android operating system offer users a wide range of multimedia capabilities, but the basic feature of recording telephone conversations is often hidden or limited. Owners of Xiaomi devices with the MIUI shell face the need to activate this option manually or search for alternative solutions, since by default it can be disabled depending on the region of the firmware.
For the Redmi 8 Pro, the issue of dialog fixation remains relevant, especially for those who use the phone for work purposes or need to save important information from conversations. There are several proven methods to achieve high-quality sound without losing a conversationalist. We will consider the standard system tools, as well as third-party solutions if standard functionality is not available.
Understanding the sound architecture in MIUI is critical to choosing the right way to go. Some versions of the software activate recording automatically when a call starts, others require manual pressing of a button during a call, and we'll take a look at the nuances so you can capture any important dialogue on your device.
Verification of the built-in recording function
The first thing a Redmi 8 Pro owner needs to do is check for a native feature in the standard Phone app. Depending on the version of MIUI and the region for which the firmware is released (Global, European or Chinese), the interface may differ, most often in Chinese versions of MIUI CN, this feature is built-in by default, whereas in global builds it may be hidden due to legal restrictions on the protection of personal data.
To find this option, open a standard call app and look at the settings menu. It's usually hidden behind three dots or a gear in the corner of the screen. If you're lucky enough to be able to use this feature, you'll see "Record Calls" or something similar. Activating this setting allows the system to automatically save the audio track of each incoming and outgoing call.
⚠️ In some regions of the European Union, call recording functionality may be completely blocked at the system level due to strict privacy laws (GDPR).
If you don’t find the right option in the phone’s settings menu, it doesn’t mean that the feature is missing completely, it may just be hidden in a hidden engineering menu or it requires activation through a region change, but before resorting to complex methods, make sure you use the latest version of the system update, as Xiaomi periodically changes the availability policy of features in different countries.
Set up automatic recording of conversations
If you find a regular feature, setting it up correctly will allow you to not worry about manual activation during important conversations. The Call Record menu usually has flexible settings that allow you to choose which calls to save, and you can set the system to record all incoming, all outgoing, or only calls from certain numbers from the phone book.
Particular attention should be paid to file storage settings. by default, Redmi 8 Pro can save records to the cloud or internal memory. To save space, it is recommended to choose to save to a microSD card, if installed. MIUI/sound_recorder/call_rec, This allows you to quickly find the right audio recordings through the file manager.
☑️ Set up automatic recording
It is also important to set up notifications, which can either alert the person that the conversation is being recorded or play back an audible signal, depending on your country's laws, and in some cases MIUI allows you to turn off the voice alert, but you should be careful not to violate local wiretapping laws.
The quality of the recording depends on the codec you choose. In advanced settings (if available in your firmware version), you can choose the compression format. AMR format takes up less space but has worse quality, whereas MP3 or AAC provide clean sound but consume device memory faster.
Use of third-party applications for recording
In situations where Xiaomi’s built-in tools don’t work or are not available, third-party apps come to the rescue from the Google Play store. However, it is worth considering that since Android 9 and especially Android 10/11 (which is relevant for the Redmi 8 Pro), Google has significantly limited third-party programs’ access to the audio stream during a call.
Popular applications like Appliqato’s Automatic Call Recorder or Cube ACR use a variety of workarounds, some requiring an applet via ADB (Android Debug Bridge) to gain deep access rights, others relying on hands-free or special VoIP drivers. The effectiveness of each method depends on the specific version of MIUI.
- 📱 Cube ACR: One of the most powerful solutions, supports recording via VoIP (WhatsApp, Viber, Telegram), but requires careful configuration of the sound source.
- 📼 Automatic Call Recorder: A classic application with a simple interface, works well on older versions of Android, but can only write on new ones through speakerphone.
- 🔊 Call Recorder - SKVALEX: The paid app, which is often updated to bypass the limitations of new Android versions, has flexible audio source settings.
When installing such software, MIUI will aggressively try to close the background process to save battery life. To avoid losing the record, you need to go to the battery settings, find the installed application, and select "No Limits" or "Out-Start" mode. Without this step, the recording may be interrupted at the most inopportune moment.
Why have third-party apps stopped working?
Activating Hidden Functions by Changing the Region
One of the most effective ways to unlock native call recording on global firmware is to temporarily change the region of the device. MIUI is structured so that the functionality depends on the location chosen. By switching the region to the country where recording is allowed (for example, India, Indonesia or Russia), you can activate hidden menus.
To do this, go to Settings → Advanced Settings → Region. Select India. After changing region, the phone may reboot some services. Go back to the Phone app and check the settings — often the right item appears. Once the function is activated, the region can be returned back, and the record will continue.
| Region | Probability of having a record | Features |
|---|---|---|
| India | Tall. | Native recording is built-in by default |
| Russia | Medium | Depends on the MIUI version, often a change is required |
| Germany | Low. | Strict GDPR laws block the function |
| Indonesia | Tall. | Full functionality without limitations |
It’s worth noting that this method doesn’t work on 100% of devices, as Xiaomi is gradually unifying firmware. However, for the Redmi 8 Pro, which is based on the popular MediaTek Helio G85 chipset (in some versions) or Snapdragon, this trick often turns out to be effective. If after changing the menu region, you don’t appear, try clearing the cache of the Phone app through the application settings.
Recording conversations through messengers
In today's world, communication is shifting towards Internet calls via WhatsApp, Viber, Telegram and Facebook Messenger. GSM-Calls don't work here, because these applications use streaming (VoIP) that is encrypted and isolated from the system.
Some third-party apps mentioned earlier (like Cube ACR) have special VoIP recording modules. They try to capture the audio stream inside the messenger app itself. However, success here is not guaranteed: once WhatsApp or MIUI is updated, the function may stop working. Often the only working option is to turn on the speakerphone and record the sound through the microphone.
💡
For quality WhatsApp calls on Redmi 8 Pro, try using the Speak mode and put the phone up with the microphone on a soft surface to avoid echoes.
There's also a method of using a second device, and although it sounds archaic, using a voice recorder on another smartphone or tablet is still the most reliable way to capture a conversation in a messenger if the software methods fail, and the sound quality in this case will depend on the acoustics of the room and the sensitivity of the microphone of the second device.
It is important to keep in mind the legal aspect: recording conversations in messengers without warning can be interpreted as a violation of the law on confidentiality of correspondence and conversations.
Where to find and how to manage recorded files
Once the conversation is recorded, the user needs to access the file. MIUI on the Redmi 8 Pro has a standard folder structure. Open the File Manager app and go to Records or manually follow the Internal Memory path. → MIUI → sound_recorder → call_rec. It stores all files sorted by date of creation.
Files usually have an extension of.m4a or.mp3, which provides good compatibility with most media players and computers. You can listen to the recording directly in the Explorer, rename the file for easy search or send it to the interlocutor via the messenger. The system also allows you to delete old records automatically if the disk space ends, if this option was activated earlier.
⚠️ Note: When clearing the cache of the Phone or Recorder app through your Android settings, the recorded files can be deleted. Always back up important conversations to a cloud drive or computer.
It's convenient to sort through a lot of records, and the Dictator app (which often combines call and voice recorder records) can create folders, tag important conversations with an asterisk, and sync them with the Mi Cloud, which is especially useful if you're planning to change your device or reset your settings to factory settings.
💡
Regular backup of the folder call_rec On external media is the only way to ensure the safety of important audio evidence or agreements.
