How to record a conversation on Xiaomi Redmi 9A built-in tools

Owners of Xiaomi and Redmi smartphones often face the need to capture important information voiced by the interlocutor during a phone conversation. The Redmi 9A, being a popular budget device, is equipped with a standard set of functions for communication, but the interface of the MIUI shell can hide some useful options from the inexperienced user. Recording a conversation is exactly the feature that can be turned off or hidden by default depending on the region on which your gadget is “sharpened”.

In this article, we will discuss how to activate the built-in call recorder without installing third-party software, which often requires unnecessary permissions and consumes battery. You will learn where audio files are stored, how to set up automatic recording for all incoming and how to circumvent restrictions if your phone does not have the appropriate button. The built-in Android system in conjunction with the manufacturer’s shell provides the best sound quality, since the recording is directly from the digital stream, not through the microphone.

Before you start setting up, it's worth noting that many countries require you to notify the person you're recording, and MIUI often automatically plays a voice notification when you activate this feature, which is an important legal nuance. Let's look at how to properly manage this tool on your Redmi 9A.

Functional verification and regional constraints

The first step before any setup is to diagnose the current state of your device, because the functionality of the standard Phone app is directly dependent on regional firmware. Global ROMs are often not capable of recording conversations due to strict privacy laws in Europe and the United States, whereas China, India or Russia (EEA) versions usually have this module in active condition.

To check if you have a native record, open the Phone app and go to settings by clicking on three dots or a gear in the corner of the screen. If you see a Call Record on the list, you're lucky to have a feature embedded in the system. Otherwise, the system may offer to download the plugin or not have such an option at all. Regional restrictions are a software block that can not always be removed by simply changing the language.

Sometimes users notice that after updating the system, the write button disappears. This is normal practice for Xiaomi, which reacts to changes in Google's policy regarding Android. However, even if the button is not in the call menu, the mechanism itself can be hidden deep in the settings or require activation through special codes, although on Redmi 9A, the problem is often solved by changing the region or using third-party shells of the call.

⚠️ Note: If you have changed region in your phone settings but the feature hasn’t appeared, your Phone app may have been upgraded to the Google Dialer version, which forcibly removes this option in global firmware. In this case, you will need to roll back the application version or install a modified version. APK-file.

It is also worth considering that the availability of the feature depends on the version of the MIUI shell. On older builds, which often stand on the Redmi 9A out of the box, the functionality may differ from the new versions.

Activation of call recording in the standard application

If you have the right functionality, it won't take long to activate it, so you have to open the Phone app and find the settings menu, which is usually hidden under a three-dot icon in the upper right or left corner of the screen, or under the gear symbol. Inside the menu, look for a section that could be called "Call Record" or "Record Settings."

When you log in to the menu, you'll see the main function switch. Activate the Automatic Call Record slider if you want your phone to record all incoming and outgoing calls without you, which is especially convenient for those who are in business negotiations and don't want to risk missing an important point by forgetting to press the button manually. Automated mode makes life much easier, but fills the device's memory faster.

To record a single time during a conversation, use the active interface. When you connect with the subscriber, the call control panel will appear on the screen. Find a button that says "Record" or the corresponding icon. Pressing it will start the process of recording the audio, at which point the interlocutor can hear a characteristic audible signal or a voice warning, if this option is enabled in the settings.

It is important to note that the quality of the recording depends on the network signal and the codec used by the operator. If the connection is poor, the digital stream can be interrupted, which will lead to artifacts in the audio file. It is also worth remembering that recording through the speaker (if you use a headset) can be conducted from one channel, so check the result with a test call.

Set up automatic recording and exceptions

The flexibility of MIUI allows the user to fine-tune the recording process. You can choose whether to record all calls or only certain numbers. To do this, select "Record Calls" from the Calls menu and specify the desired option: "All numbers", "Numbers not saved in contacts" or "Selected Numbers" This helps save space on the drive by filtering unnecessary conversations with pizza or delivery services.

The notification settings are worth special attention. The legality of recording a conversation without warning varies from country to country. In the recording settings, find "Warn about recording" or "Reproduce sound." If this item is active, the system will voice the caller, "Conversation is recorded." By disabling this option, you can record it secretly, but remember the legal liability.

The file save format can also be adjusted. Although Redmi 9A defaults to M4A or MP3 format (depending on the codec version), the encoding quality can be changed in advanced settings if this option is available in your firmware version. High quality requires more space but provides better speech legibility.

Remember to check the list of recorded files periodically. Autoclean can be configured to delete old records if the phone's memory is full, which will save you from a situation where an important conversation is not recorded due to lack of space.

Where to look for saved conversation files

After the conversation is over, the audio file is stored in the smartphone’s internal memory. The standard path to the directory with entries on Xiaomi devices is as follows: → MIUI → sound_recorder → call_rec. This is where all your conversations are, sorted by date and time.

You don't have to go to the file manager to access the latest records quickly. Open the Recorder app, which is system-based. At the top of the screen, switch to the Calls tab or find the corresponding section in the menu, and here the files are already sorted and provided with information about the phone number and the duration of the conversation.

If you plan to transfer files to your computer or send them by mail, the best way to use the built-in file manager MIUI. It allows you to quickly select the desired tracks, compress them into an archive or send them via Bluetooth and messengers. The file format is usually compatible with all modern players and OS.

💡

Save important conversations to the cloud (Google Drive, Mi Cloud) immediately after the end. The internal memory of budget smartphones can fail, and local files will be lost.

Remember that when you clean the cache of the Phone or Dictator app, files can be deleted unless they are marked as important.

Solving the problem of missing a record button

The situation when the app "Phone" is not a record button or item in the settings, is the most common for owners of global versions of Redmi 9A. This is due to the fact that Google has implemented restrictions in Android 9 and higher, prohibiting third-party and system applications to record audio from the line without special permissions that are given only to certified applications. Xiaomi in global firmware often replaces its call to Google Dialer, where this feature is not.

There are several ways to solve this problem, and the first and most reliable is to install a modified version of the Google Phone Mod app or return to an old version of the system call. MIUI. But it does require downloading. APK-Files from unverified sources, which carries security risks, and the second way is to use third-party apps from the Play Market, such as Cube. ACR Automatic Call Recorder.

Third-party applications are based on the principle of recording sound from a microphone or through special accessibility services (Accessibility Service), they can request broad permissions, but often are the only way for users who do not want to reflash the phone, recording quality in such cases can be lower, especially if the speaker is turned on.

⚠️ Warning: Installing modified system applications (mods) can cause your phone to run unstable, advertise or even lock your device with Google Play Protect antiviruses.

If you choose to install a third-party recorder, be sure to give it all the permissions you request, including access to the microphone, phone and storage. In the settings of the recorder application itself, you often need to turn on the Recording Method: Voice Call (Audio Source) or similar, so that the sound is clear rather than deaf.

Alternative methods and third-party software

When embedded tools are powerless or limited, specialized applications come to the rescue, a niche that has long been dominated by Cube ACR. It can bypass Android’s limitations by recording sound even through VoIP channels (Viber, WhatsApp, Telegram), although its functionality has also been stripped with the latest Android updates.

Another option is to use Screen Recording with sound. MIUI has a built-in screen recording feature that allows you to capture video of what's happening on the display along with sound. If you turn on the screen recording during the call and select the sound source of the Microphone and Speaker, you get a video file with a conversation. This is not the most convenient way, but it works on 100% of devices without root rights.

For advanced users, there is a way to get Root rights. With superuser rights, you can install Magisk modules that unlock the system's call record at the kernel level, which gives you perfect results, but it takes away warranty and can "brick" Redmi 9A if you mishandle it.

When choosing a third-party solution, focus on the reviews and date of the last update of the application. Old recorders may simply not run on the current version of Android.

Frequent questions and problems with sound quality

Users often complain about the quiet sound of the recording or the complete absence of the interlocutor’s voice in the file, which is due to the fact that modern smartphones use noise cancellation, which can treat the voice of the interlocutor as noise if it is broadcast through the speaker, in such cases, it helps to turn on the speakerphone during recording, if the recording method is used through the microphone.

Another problem is that you interrupt the recording when you make a second call or switch to speaker, and the system can suspend access to the audio stream in favor of a priority process, and the sound quality also depends heavily on the operator: when you use the codec, you can use the audio stream. HD Voice recording will be cleaner than standard GSM-codec.

If files are written but not opened, check their format. Sometimes the system recorder creates files in a format that a standard player does not see (rarely, but it does). Try opening them through the VLC Player or converting them online. Also make sure the file is not corrupted when copying.

To sum up, Redmi 9A has powerful potential for recording conversations, but access to it depends on the software version. Using built-in features where they are, and competent alternatives where they are not, you can always save important information.
