The modern Xiaomi Redmi 9 series provides users with a lot of functionality, but sometimes standard features seem limited. One of these features that often raises questions is recording phone conversations. Device owners face the need to save important agreements, record order details or simply have proof of dialogue. However, depending on the version of the MIUI operating system and regional settings, this option may be hidden or not work properly.
In this article, we will discuss in detail all available methods of activating a voice recorder during a call. You will learn how to turn on automatic recording, what to do if the standard phone application does not provide this, and what alternative solutions exist. Attention: many countries require the law to alert the interlocutor about recording, so use this feature responsibly. We will look at the nuances of the Google Dialer shell, which often replaces the native caller on global firmware versions.
The setup process can seem confusing due to the constant changes in Android security policy.Google actively restricts apps from accessing the microphone during a call, which creates technical difficulties for developers.However, there are proven ways to get around these restrictions for the Redmi 9 model.
Standard voice recorder capabilities in MIUI
On most Xiaomi devices, including Redmi 9, the recording feature is built directly into the system call app. This is the most stable and high-quality way to capture audio, since it works at the system level, rather than through the speaker microphone. To check for this option, you need to open the Phone app and go to the settings menu, usually indicated by three dots or a gear in the upper right corner of the screen.
If you see Call Recording, you're lucky that your firmware version supports native function, that you can set up automatic recording of all incoming and outgoing calls, or only certain numbers. It's important to understand that the audio quality in this mode will be perfect, because it's recorded from a digital line, not through a speaker. However, on global firmware versions (Global ROM), this item is often missing due to Google's licensing restrictions.
If you don't have the right menu in your standard settings, don't despair. There are several workarounds that allow you to return this feature. One of these methods is to change the region of the device. Go to Settings → Additional → Region and select a country where the entry requirements are less stringent, such as India or Indonesia. After changing the region, check the settings again - often the desired item appears instantly.
It is worth noting that changing the region can affect the performance of some local services and promotional offers in system applications. Therefore, once the write function is enabled, the region can be returned back, although in some cases the setting may be reset. The alternative is to use a special code to log into the engineering menu, but on modern versions of MIUI 12 and higher, this method is often blocked by developers for security reasons.
- 📞 Native recording provides the best sound quality without surrounding noise.
- 🌍 Changing the region to India or Indonesia often unlocks hidden features.
- ⚙️ Automatic recording saves time and ensures that all details of the dialogue are saved.
- 🔒 Global firmware versions may restrict access to microphone by third-party applications.
Google Dialer Problems and Their Solutions
Starting with certain versions of the MIUI shell, Xiaomi was forced to replace its own call interface with Google Dialer, which was due to the tightening of the privacy policy in the Android operating system. In the standard Google Phone application, the recording function is also present, but it has one critical feature: when you activate a recording, the interlocutor hears a loud voice notification “Conversation recording has begun” in the language of the phone interface.
This notification cannot be disabled by standard means in the latest versions of the application. However, there are modified versions of Google Dialer that bypass this restriction. Installing such an application requires removing updates to the standard call or using special scripts through ADB, which can be difficult for the average user. A simpler, but less reliable way is to install older versions of the application where the security hole has not yet been closed.
⚠️ Note: Installation of modified system applications (APK) You can inadvertently install malware that will gain access to your contacts and personal correspondence. Use only trusted forums and sources with good reputations.
If you don't want to risk the security of your device, you can try changing the settings of the Google Phone app itself. Go to Settings → Recording calls and turn on the option "Automatically Record Selected Numbers." Even with a voice alert, this can be an acceptable option for business purposes where recording is more important than stealth. It's also worth checking if you have the latest version of the app from Google Play - sometimes rolling back to the previous version returns the ability to record quietly, although this feature quickly closes.
For advanced users, there is a method of replacing the system files of the call with a version for a region where voice warning is not required (for example, some versions for Taiwan or Singapore), this process requires obtaining Root rights, which automatically deprives of warranties and can lead to system failure if you do not act correctly. For Redmi 9, this is especially true, since the device is built on a MediaTek processor, which unlocks the bootloader has its nuances.
Use of third-party applications
When the built-in tools don't work or work, third-party solutions come to the rescue from the Google Play store. The leader in this niche has long been the Call Recorder app - ACR from NLL. It can bypass many system limitations using special availability modes. However, after the release of Android 10 and above, Google closed many loopholes, and now for the full operation of such programs often requires complex initial configuration.
Another popular option is the Cube ACR app. It supports recording not only normal calls, but also conversations through messengers (Viber, WhatsApp, Telegram). To work on Redmi 9 with a MIUI shell, you need to give the application a maximum set of permissions, in particular, you need to turn on Autostart, remove battery restrictions and allow display on top of other windows. Without this, the system will aggressively “kill” the recording process in the background.
Instructions for setting up rights for a third-party recorder on Xiaomi:
- 📲 Go to Settings. → Annexes → All applications.
- 🔋 Find your recorder, select Charge Savings and set “No Limits».
- 🚀 Enable AutoRun in the same app settings menu.
- 🎙️ Provide all requested permissions for microphone and phone.
And you have to consider that third-party apps often write sound through a microphone, not a line, which means that the quality of the recording will depend on how you hold the phone. If you put the phone to your ear, the body can drown out the sound, and the voice of the interlocutor will be quiet, in such cases, it is recommended that during a conversation you turn on the speaker so that the microphone can catch both voices evenly.
💡
For better performance of third-party recorders on MIUI, be sure to add the app to the Favorites list in the recent app menu (swig down the icon) so that the system doesn’t unload it from memory.
Comparison of recording methods on Redmi 9
The best way to choose depends on your technical skills and audio quality requirements. Native methods are always preferred because they are battery-free and integrated into the system. Third-party applications are a compromise that provides functionality, but require sacrifices in the form of autonomy and potential failures. Below is a table to help determine the choice.
| Method | Sound quality | Difficulty setting up | Security risks | Voice notification |
|---|---|---|---|---|
| Built-in function (MIUI) | High (digital) | Low. | Absent. | No. |
| Google Dialer (standard) | High (digital) | Low. | Absent. | Got it (loudly) |
| Third-party annexes | Medium (microphone) | Medium | Medium (access to data) | No (usually) |
| Modified APKs | High (digital) | Tall. | High (instability) | No. |
As you can see from the table, if you are critically concerned about the lack of voice warning and high quality, but the standard feature is hidden, you will have to choose between complex mod installation and using third-party software with loss of quality. For most Redmi 9 users, the optimal balance is to use the Call Recorder application with the correct setting of access rights, despite the possible loss in the purity of the sound.
Also worth considering is the amount of space you take up. High-quality recording (WAV format) takes up significantly more space than compressed MP3 or AMR. If you plan to record hundreds of hours of conversations, set up in-app compressed saving or automatic upload to the cloud. Xiaomi's built-in voice recorder usually lets you choose the recording format in settings, which is convenient for saving memory.
☑️ Checking settings before recording
Where are the records stored and how to find them
Once you've set up successfully, the question is, where do you save your files? In Android on Xiaomi, the path to the records may vary depending on the method you use. MIUI Files are usually located on the path of the internal drive → MIUI → sound_recorder → call_rec. Here, files are sorted by call date and time, making it easier to find the right dialogue.
If you use Google Phone, records are often stored in the cloud or in the Recordings folder at the root of internal memory. In newer versions of Android, access to the root folder can be limited, so it is easier to search files through the built-in File Explorer, going to the category of Audio or Records. Third-party applications create their own folders, such as CallRecorder or ACR, which are also easy to find through file search.
You can use any media player to listen to it. However, if you've been recording in a specific format, you might need to convert. Xiaomi's built-in player is great at most formats. If you're planning to transfer the recordings to your computer, it's most convenient to do it through a computer. USB-cable (MTP) Or through cloud services like Google Drive or Mi Cloud.
⚠️ Warning: When you reset your phone to a factory setting, all local records will be permanently deleted, and it is recommended to regularly back up important conversations on an external drive or in the cloud to avoid losing critical information.

Legal aspects and ethics
The use of the call recording function is governed by the laws of the country.In many jurisdictions, recording a telephone conversation without warning the other party is illegal and may entail legal liability.Even if technically you can do so on Redmi 9, you are required to comply with privacy and data protection laws.
Business correspondence often uses the one-sided consent rule, but in private conversations the requirements are stricter. Voice notification in Google Dialer is implemented precisely to comply with these norms. Ignoring this fact can lead to the fact that the recording will not be accepted by the court as evidence, or you will be the subject of a lawsuit for violation of privacy.
Always evaluate the appropriateness and legality of your actions. If the record is needed to record the terms of the contract with the bank or delivery service, this is one thing. If it is a personal conversation, it is worth thinking several times before saving the audio. The technical capabilities of the Xiaomi smartphone do not relieve the user of responsibility for compliance with ethical and legal norms.
💡
The technical ability to record does not mean a legal right to record it, but always warn the person if the law of your country requires it.
