Xiaomi’s smartphones, including the popular budget model Redmi 9A, are equipped with a MIUI shell that provides users with advanced system management capabilities. One of the most popular features for business people and ordinary users is the ability to record telephone conversations. This can be necessary to save important information, confirm agreements or just for a personal archive.
Owners of Redmi 9A devices often face situations where standard recording functionality does not work as expected or requires additional customization, due to changes in the privacy policy of Google, which owns the Android operating system. Starting with Android 9 and higher, access to the microphone by third-party applications during the call was significantly limited, which affected the operation of the built-in tools.
However, Xiaomi engineers have found ways to get around these limitations in their firmware. In this article, we will detail how to activate native recording, what settings to check first, and what to do if the standard mechanism doesn’t work. You will learn about the intricacies of working with Google Dialer and MIUI Dialer, and also consider alternative methods of recording audio.
Built-in MIUI and Google Dialer capabilities
The Redmi 9A has a Google call app installed by default, which can be replaced by MIUI Dialer in some regions and firmware versions, and the difference is significant because it is the type of caller that determines the availability of the recording function without installing additional software.
To check for built-in functionality, you need to open the Phone app and go to settings through a three-point menu. If you have Call Record on the list of options, you're lucky to have access to the feature. However, it's often hidden or not available at all because of regional constraints, in which case the system may offer third-party applications that, however, are intermittent.
It's important to understand that the automatic recording in the native application is the most stable, it doesn't require constant interaction with the screen, it's not interrupted by incoming notifications. If you see the AutoWrite switch, it should be activated, so that you can save all incoming and outgoing calls to the device's memory without you.
⚠️ Note: When using embedded recording, the interlocutor may hear a characteristic beep or voice warning that the conversation is being recorded, which is a requirement of many countries' legislation, and it is impossible to circumvent it by software-based means.
If the settings don't have the right switches, your firmware version may have limitations, so it's worth checking the region in your phone settings. Changing the region to India or Indonesia will sometimes unlock hidden features, because recording conversations is standard practice in these countries. After changing the region, restart the device and check the settings of the calls again.
Activating Hidden Functions Through a Region Shift
One of the most effective and safest ways to access a full-fledged Redmi 9A conversation record is to change the region of the device, which doesn't require root rights or complex flashing. The logic is simple: some countries require manufacturers to provide users with tools to control communications, so the functionality is unlocked by default.
To do this, go to the Settings menu, then select the Additional section and find Region. In the list that opens, select India, Indonesia or Pakistan. The system can warn you about changing some settings and date format - agree with the changes. After that, the phone may require a reboot, although often the changes are instant.
Once you change region, go back to the Phone app, click three dots in the corner, and select Settings, then Call Record. New options should appear here, you can set up automatic recording for all numbers, or select specific contacts from the phone book, and you can also set up a file storage format and location.
It's worth noting that changing your region doesn't just affect your call, you can change your pre-installed apps, your Themes store themes, and even the display of some system services, for example, in some regions, features that are connected to local services that don't work in Europe or the CIS are becoming available, and if you don't plan to use these services, it won't be a problem.
⚠️ Warning: Changes in the region may affect work NFC If you are actively using Google Pay or Mi Pay, check their performance after changing settings. In rare cases, banking applications may require a region to return to its original state.
Use of third-party applications for recording
If native methods don't work or require constant regional change, Google Play apps come to the rescue, but because of the limitations of the Android API, most of them can't record audio directly from the line, instead using a microphone, which leads to recording of ambient noise and a decrease in the quality of the voice of the interlocutor.
One of the most popular solutions is the Call Recorder app - ACR. It has many settings and supports various audio compression formats. To work correctly on the Redmi 9A with a MIUI shell, you need to give the application all possible permissions, including access to the microphone, phone and storage, without which the system will block the recording.
Another option is Cube ACR, which is an application that tries to use the App Connector to intercept audio, and when installed, it will ask for special access in the special settings, which allows you to bypass standard restrictions and record sound more cleanly, although not perfectly.
- 📱 Call Recorder - ACR: powerful tool with flexible format configuration and cloud synchronization.
- 🎙️ Cube ACR: Use accessibility services to improve sound capture.
- 📼 TapeACall: a popular solution, but often requires a paid subscription to work.
- 📞 Automatic Call Recorder: a simple application with a minimalist interface and basic functionality.
When using third-party software, it is important to consider the aggressive MIUI energy saving policy. The system can automatically close the background processes, considering them harmful or energy-intensive, to prevent this, you need to lock the application in memory and remove the battery restrictions.
Configuring Permits and Energy Saving
The MIUI shell on the Redmi 9A is known for its strict power optimisation, which means that any call recording app running in the background can be forced to stop by the system at any time, and permissions must be configured to avoid losing important conversations.
Go to Settings → Applications → All Apps. Find your recording app (or standard call if you use it) in the list. Go to Battery and select No Limits mode. This will prevent the system from "sleeping" the recording process. It is also recommended to enable auto-run for this application.
☑️ Configuring energy saving for recording
Additionally, check permissions in the Permits section, make sure that the "Microphone", "Phone", "Contacts" and "Memory" points are marked. If the application requires access to "Map on Other Windows" or "Special Features", these points must also be activated. Without them, recording can begin, but break when the screen is locked.
Another important thing is the ad blocker. Built-in ad tracker. MIUI (MSA) It can sometimes conflict with background processes, although shutdowns MSA This does not guarantee the operation of the record, it is a general recommendation to improve the stability of the system. → Access to personal data.
⚠️ Warning: Granting full permissions to third-party apps carries privacy risks. Use only proven programs with high ratings and positive reviews to avoid personal data leakage.
Comparison of methods of recording conversations
The choice of recording method depends on your priorities: sound quality, usability or data security. Native methods are certainly preferable, since they are integrated into the system and are not a waste battery, but they may not be available in your region without "dancing with a drum".
Third-party applications offer more freedom, but require careful tuning, and the sound quality often depends on the Redmi 9A speaker model and microphone. In noisy environments, recording through the microphone can be almost inaudible. Below is a table comparing basic methods.
| Method | Sound quality | Stability | Difficulty setting up |
|---|---|---|---|
| Built-in (region change) | High (digital) | Tall. | Low. |
| Google Phone (standard) | High. | Medium | Low. |
| Third-party annexes | Medium/Low | Low. | Tall. |
| Speaker + voice recorder | Low (noise) | Tall. | Medium |
As you can see from the table, switching from one region to India or Indonesia is the most efficient way to get a high-quality digital record without losing sound quality, the only way to record the voice of the other person as clearly as your own without using hands-free.
If you don't want to change the settings, you have a hands-free phone with a voice recorder on, which is inconvenient because it requires you to hold the phone in your hands or put it on the table, but it guarantees recording in any conditions, even if the software methods are blocked by the operator.
Record management and file search
Once a record is made, it's important to know where to find it. Depending on the method you choose, files can be saved in different directories. In a standard Google Phone application, the records are usually inside the application itself. When you open the call history, you'll see the recorder icon under the subscriber number, if the record is made.
To access files through a file manager, the path is usually as follows: → Call or Internal Memory → MIUI → sound_recorder → call_rec. Files may have an extension.mp3,.m4a In new versions of Android, access to a folder Android/data limited, so use the built-in conductor MIUI or Google Files.
How to copy the records to a computer?
Auto Cleanup is a useful feature to keep in mind, and you can set a limit in your recording settings to delete old files when the space is over, or keep records for no longer than 30 days, which will prevent Redmi 9A from overflowing, which is limited in the base version.
- 📂 The path to files is often hidden in system folders, use the search extension.m4a.
- ⏳ Set up autodelete so as not to clog the device memory.
- ☁️ Regularly back up important conversations to the cloud.
Remember, conversation records files can contain sensitive information. When transferring a phone for repair or sale, be sure to check the audio folders and delete the extra. Formatting a phone is the most reliable way, but manual verification is also good.
Problem Solving and FAQ
Users often find that the recording begins, but the file is empty or contains only silence. This is a classic problem of Android limitations. If changing the region did not help, try to turn on speakerphone during a conversation - this often "wakes up" the microphone of recording in third-party applications.
Another problem is that there are no recording notifications, and in MIUI, notifications can be hidden, check the notification settings for the Phone app, and make sure that the Call Record category is not blocked, and sometimes cleaning the call app cache through the app menu helps.
The legality of recording is also important. In many countries, recording a conversation without warning is illegal by law. Use the knowledge responsibly. Technological ability does not always mean legal law. Always check the laws of your region before starting a mass recording.
