Xiaomi smartphone owners often face the need to capture important information during a phone conversation. The Redmi Note 8 Pro model, released in 2019, remains popular due to its price-performance ratio, but the issues of audio recording customization remain relevant. The built-in MIUI system allows you to solve this problem without installing additional software, but the functionality can be hidden from the inexperienced user.
There are several ways to save dialogs, each with its own features and limitations related to Android versions and regional firmware settings. Global firmware versions often have restrictions due to privacy laws in different countries, while Chinese versions are free of such locks. Understanding these nuances will help you choose the best method for your device.
In this article, we will discuss in detail the algorithms for activating automatic and manual writing, and also consider alternative options for cases where standard functionality is not available, you will learn how to manage recording files, where to look for them in the device’s memory, and how to circumvent system restrictions without obtaining root rights.
Use of built-in call recorder
The most reliable and high-quality way to capture a conversation is to use the regular Phone application developed by Xiaomi. Unlike third-party utilities, the system module has direct access to the audio stream, which provides clean sound without extraneous noise and echoes. To activate this feature, you need to go to the call settings, where the basic control parameters are hidden.
Open the Phone app and click on the three dots in the top right corner of the screen to open the settings menu. In the list that opens, select Call Record. Here you will find the Automatic Call Record switch that can be activated for all numbers or select specific contacts from the phone book, which is especially convenient for monitoring incoming customers or important business partners.
⚠️ Note: In some global versions MIUI (Europe, India) the feature of the built-in recording may not be available due to local privacy laws. If you do not see the record menu, try changing the region in the phone settings to Singapore or Russia, but this does not guarantee the result on all builds.
It is important to note that the quality of the recording depends on the microphone and dynamic range of your Redmi Note 8 Pro. The system automatically adjusts the volume levels, but in conditions of poor communication, the interlocutor can be heard worse. For maximum quality, it is recommended to use a hands-free mode or headset if the built-in mixer does not cope with the voice balance.
All saved files are automatically sorted and stored in a special folder, accessed through a standard Explorer. MIUI/sound_recorder/call_rec, file-storage MP3 or M4A. This makes it easy to transfer records via instant messengers or save them to cloud storage for long-term archiving.
☑️ Checking the recording settings
Set up automatic recording for contacts
MIUI allows you to flexibly configure the rules for archiving conversations, which eliminates the need to manually turn on the recorder every time. You can configure the system so that it ignores personal calls and records only work contacts, or vice versa. This segmentation helps save space in the memory of the smartphone and makes it easier to find the right files.
In the call recording settings menu, select the option “Write down certain numbers” and you will be given two options: record all calls except those selected, or record only the selected numbers. The second option is more secure from a privacy perspective, requiring you to add contacts to a special “Blacklist” of exceptions or, conversely, to a priority list.
- 📞 All numbers: The system will save every incoming and outgoing call indiscriminately.
- 📇 Favorite Contacts: Entry will only go to those in the phone book.
- 🚫 Unknown numbers: useful for fixing calls from scammers or spam.
- 🔇 Quiet Mode: Option to disable audio recording notification (not available in all versions).
When selecting an automatic recording, the system can play a voice alert that a conversation is being recorded, which is a requirement of many countries, and it is rarely possible to disable it by regular means, but there are workarounds associated with replacing the system application of calls with modified versions of Google Dialer with support for hidden recording.
Third-party applications for recording conversations
When built-in tools fail, third-party apps come to the rescue, but since Android 9 and especially Android 10 and 11, Google has significantly restricted third-party software access to the microphone during a call, leading many popular apps to stop recording the voice of the interlocutor, recording only silence or your voice.
One of the most effective solutions at the moment is the Call Recorder app - Cube ACR. It uses special methods to bypass system constraints, switching the sound source to VoIP or using accessibility services. To work correctly on the Redmi Note 8 Pro, you need to give the application maximum resolutions and turn off battery savings.
| Annex | Compatible with Android 10+ | Recording quality | Advertising |
|---|---|---|---|
| Cube ACR | High (with App Connector setting) | Good. | Got it in |
| Automatic Call Recorder | Medium (often writing silence) | Average. | There is. |
| TapeACall | High (conference) | Excellent. | Paid subscription |
| Blackbox Call Recorder | Medium | Low. | There is. |
Installing third-party software requires careful attention to the security settings MIUI. The system aggressively kills background processes, so you need to fix the application in memory. To do this, open the menu of running applications, press the icon of the desired program and press the lock, and also in the battery settings, select the "No restrictions" mode.
Why have third-party apps stopped working?
Recording through speakerphone and voice recorder
There is a "grandfather" method that works on any phone without exception, including the Xiaomi Redmi Note 8 Pro. It consists of using a built-in voice recorder to record sound played through the speaker. This method does not require the installation of additional software, but has a significant disadvantage - reducing sound quality and recording all the surrounding noise.
To do this, you can turn on speaker immediately after you connect to the subscriber. Then quickly launch the standard Dictator app and start recording. The conversation will be conducted through the speaker, and the phone's microphone will capture both voices. It is important to ensure silence in the room so that extraneous sounds do not drown out the interlocutor.
This is a good backup when software is not available, but for long interviews or important negotiations, the quality may be poor, and the battery is consumed faster because of the simultaneous operation of the speaker at high volume and the microphone.
💡
To improve the recording quality through the recorder, place the phone on a soft surface with speakers upwards to avoid vibrations and body resonance that create an unpleasant hum in the recording.
Search and management of records
Once the conversations are recorded, it's a matter of storing and processing them, and the MIUI file system has a very clear structure, and you can find your records in a number of ways, and the easiest one is through the Dictophone app, where there's a separate tab for calls, sorted by date.
If you need to copy files to your computer or send them to the cloud, it's more convenient to use a file manager. → MIUI → sound_recorder → call_rec. It stores all the audio files, and you can rename them, delete them, or move them to other directories for systematization.
- 📂 Sorting: In the Explorer, you can sort files by date, size or name.
- ✂️ Editing: Built-in editor allows you to cut the beginning and end of the recording, removing unnecessary pauses.
- ☁️ Sync: set up automatic download of the record folder to Google Drive or Mi Cloud.
- 🗑️ Cleanup: Delete old files regularly, as they can take up a significant amount of memory.
The file format is usually MP3, which ensures good compatibility with any media players and computers.If you plan to use the record as evidence in court or for official purposes, it is recommended that you copy the file to a secure folder or external media immediately after the call to avoid accidental deletion when cleaning the cache.
Solving problems and mistakes
Redmi Note 8 Pro users may experience a situation where the recording is ongoing, but the voice is not heard, most often due to noise cancellation or conflicting Android versions, in which case resetting the settings of the Phone app to factory settings through the application menu helps.
Another common problem is the lack of recording notice, which is mandatory in some regions and can only be circumvented by flashing the device to a global version of another country (for example, Indonesia or Taiwan), where such restrictions are milder, but flashing carries the risk of loss of warranty and data.
⚠️ Note: When updating the system MIUI After each major update, check the Call Record menu to make sure the feature is active.
If nothing works, you can try using USB debugging mode and ADB commands to force the activation of hidden functions, but this requires a computer and some technical knowledge. For most users, the optimal solution is to use proven third-party applications with the right permission settings.
💡
The most stable result on the Redmi Note 8 Pro is the built-in recording feature, and if it is not available in your region, the best choice is the Cube ACR app with a configured VoIP sound source.
