Xiaomi’s Redmi Note series has long established itself as one of the most popular devices on the market due to its excellent price-performance ratio. The Redmi Note 8 Pro, launched in 2019, is still in active use by millions of users around the world, remaining a reliable working tool for everyday tasks. One of the key features that is often required in business correspondence or when communicating with official services is the ability to capture the audio stream during a phone conversation.
However, owners of devices based on the MIUI shell often face confusion in settings, as the interfaces of different versions of the Android operating system can be significantly different. In older versions of firmware, this option was hidden or required the installation of third-party software, while modern updates offer built-in, but not always obvious solutions. Recording a conversation on the Redmi Note 8 Pro can be done both automatically and manually, and understanding these differences is critical to preserving important data.
In this detailed guide, we will take a look at all the nuances of the built-in call recorder, consider possible problems with file formats, and suggest alternative methods for recording audio if the standard functionality does not work on your device for some reason, you will learn where to look for ready-made files and how to configure the system so that no important word is lost.
Built-in MIUI shell capabilities for recording
The MIUI shell, which is installed on Xiaomi smartphones, including the Redmi Note 8 Pro, has its own software module for recording telephone conversations. This tool is integrated directly into the Phone application, which allows it to work more stable and faster than third-party counterparts from Google Play. Activation of this feature does not require obtaining superuser rights (root) or complex flashing of the device, all the necessary switches are in the standard settings menu.
To access the recording management, you need to open the Phone app and click on three dots in the upper right corner of the screen, then select Settings. In the menu that opens, you should find the Call Record section. This is where all the key settings that allow you to flexibly manage the audio saving process are concentrated. The user can choose whether the files will be saved to the Mi Cloud cloud or remain exclusively in the internal memory of the device.
💡
Recorded conversation files are saved by default in the folder MIUI/sound_recorder/call_rec, However, the path may differ depending on the Android version.
It is important to note that in some regions or firmware versions (especially global ones that have been upgraded to Android 10 and above), the functionality may be limited by the country of use, in which case the menu item may be missing or not work correctly. If you did not find the options described below, it is possible that your region in the phone settings (Settings → Additional settings → Region) is set to a country with severe restrictions, such as India or the EU countries.
⚠️ Note: Some countries require voice notification to start recordings, and make sure that your actions do not violate local privacy laws.
Set up automatic and manual recording
Inside the recording settings menu, the user encounters two main modes of operation: automatic and manual. Automatic recording allows you to save every incoming or outgoing call without having to press any buttons during the conversation, which is especially convenient for people who often forget to turn on the recorder manually or need an archive of all conversations for reporting.
To activate this mode, you need to turn the "Automatic Record" slider into the active position in the "Call Record" menu. The system will suggest clarifying the conditions: record all calls or only numbers from certain groups (for example, "Unknown numbers" or specific contacts from the phone book). The flexibility of the MIUI settings allows you to create a thin configuration, cutting off unnecessary noise and storing only important information.
If you don't need automation, you can use manual mode, in which case, during an active conversation, a special button with a voice recorder or the words "Record" appears on the screen, pressing it initiates the storage of audio, the advantage of manual mode is that you decide which part of the conversation to save, and do not occupy the phone's memory with couriers or advertising agents.
- 📞 All calls: the system saves absolutely every incoming and outgoing call indiscriminately.
- 📇 Selective Contacts: Recording is only for numbers added to the blacklist or certain contact groups.
- ❓ Unknown numbers: a useful feature for recording calls from scammers or intrusive services.
- 🚫 Disabled: recording is made only by explicit user command during a conversation.
Keep in mind that when you turn on automatic recording, you consume the internal space of the drive. Although modern compression codecs are quite effective, long conversations in high quality can quickly exhaust free space if you do not use a microSD card to store media.
Problems with formats and audio quality
One of the common problems faced by owners of the Redmi Note 8 Pro and other Xiaomi models is the choice of file format to be saved. By default, the system can use the AMR format, which provides a small file size but has low sound quality, often making speech indistinct against noise. For important negotiations, it is preferable to use the MP3 or AAC format, which provide significantly better clarity.
The format change is done in the same call recording settings menu. If the "Record Format" option is missing or inactive, this may be due to limitations of the current version of MIUI or regional settings. In some cases, switching the region to Singapore or Indonesia will unlock additional audio codecs, but this may affect the operation of other system applications, such as the theme store or browser.
Why can the recording be interrupted?
The quality of the recording also depends on the microphones. The Redmi Note 8 Pro uses a noise reduction system that in some scenarios can mistakenly mistake the voice of the interlocutor for noise and mute it. To improve the result, it is recommended during important conversations not to palm the lower part of the smartphone where the microphone holes are located, and if possible use the headset.
| Parameter | AMR format | MP3 format | AAC format |
|---|---|---|---|
| Sound quality | Low, mono. | High, stereo. | Very tall, stereo. |
| File size | Minimum | Medium. | Medium/Large |
| Compatibility | All players. | Universal. | Modern devices |
| Recommendation | For drafts. | For important calls. | For archiving |
Alternative methods and third-party applications
In situations where the built-in MIUI functionality is unavailable, blocked by the carrier or is not working correctly, third-party solutions from the Google Play store come to the rescue. Applications like Call Recorder - ACR, TapeACall or Cube Call Recorder are able to bypass some system limitations, albeit with varying success on different versions of Android.
The main difficulty of using third-party software on the Redmi Note 8 Pro is an aggressive policy of managing the power consumption of the MIUI shell. The system can force the recording process to be considered background load. To avoid this, you need to manually configure permissions for the installed application: allow auto-start, work in the background and access to the microphone without restrictions.
☑️ Setting up a third-party recorder
Some users have resorted to using another device to record a conversation over speakerphone. Despite the archaic method, it remains the most reliable way to obtain an audio file that cannot be blocked software. In addition, using a headset with a built-in voice recorder or connecting a smartphone to a computer through specialized software to record system sound are also viable options.
- 📱 Google Phone: on some global firmware, a regular “calling” from Google has a built-in recording, but warns the interlocutor in voice.
- 🎧 Recorder through speaker: Enabling recording on the second device when talking on speakerphone.
- 💻 PC recording: using emulators or programs to tranulate the screen and sound of a smartphone to a computer.
⚠️ Warning: Third-party apps often require extensive permissions, including access to contacts and call history. Use only proven, high-rated software to avoid personal data leakage.
Where to look and how to manage recorded files
Once recorded successfully, conversations are automatically stored in the device's memory, and you can find them in several ways, the easiest way is to open the Dictator app (if the recordings are synced with it) or the Phone app, go to the call history, select a specific number, and click on the recorder icon next to the call date.
To access the files themselves through the file manager, you need to go along the path: Internal Memory → MIUI → sound_recorder → call_rec. Files are sorted by date and time of creation, and file names usually contain a phone number and date in the format of GGMM-FM-FM-SS, which makes it easier to find the right dialogue in a large amount of data.
💡
Regularly check the folder with records and copy important files to the cloud or to the computer, as when resetting settings or flashing them will be irretrievably lost.
File management includes the ability to listen, rename, delete and send. MIUI allows you to send recordings directly through messengers (WhatsApp, Telegram) or email. There is also an editing feature that allows you to cut off unnecessary parts of a conversation, such as a beep or greeting, leaving only the essence of the conversation.
