Xiaomi smartphone owners often face the need to keep important negotiations, whether business agreements or conversations with government agencies. The Redmi 9C, a popular budget device, has all the technical capabilities for recording audio, but the software limitations of the Android operating system and the MIUI shell can hide this feature from the user. In recent versions of firmware, Google and Xiaomi have implemented strict privacy policies that change the standard algorithm for activating the recorder.
The main difficulty is that the interface may differ on different versions of the software. While in the early stages of sales of Redmi 9C feature was available out of the box, after the global updates to Android versions 11, 12 and higher, the system often moves to the standard Google Phone, which has its own nuances. Understanding what kind of dialer is installed on your device is key to successful configuration.
In this guide, we will take a look at all the ways you can activate recording conversations, from standard system settings to specialized applications. You will learn how to bypass the limitations of regional settings and where to look for hidden menus if the standard path does not lead to the desired result. It is important to carefully monitor each step, as improper settings can lead to no audio in the recording or complete failure of the function.
Verification of the MIUI shell version and call type
The first step before you start setting up is to determine exactly the version of the operating system installed and the type of application for calls. Xiaomi 9C can have different builds depending on the region of purchase and the time of the device exiting the box. Usually it is MIUI Global or MIUI Russia, and this is what depends on the availability of native recording function.
You need to go to the settings menu and find the About Phone section. Here you are interested in the "Version" line. MIUI». If you have a version installed 12.0.x or higher, the probability of using a standard Google Dialer is almost 100%. In older firmware or in Chinese versions, a native dialer can be used. MIUI, which has a built-in recording button without warning of the interlocutor.
It's also important to check which app is the default for making calls. Go to Settings → Apps → App Management and find the Phone list. If the icon is blue with a white handset is Google Phone, if it's green or white with the MIUI logo is the native dialer, then your next strategy depends on this choice.
⚠️ Warning: Forced replacement of the system application "Phone" by a third party can lead to unstable communication or disappearance of contacts.
In some cases, the system may offer to update the Phone app through the Google Play Store, and by doing so, you are finally moving to the Google ecosystem, where the American giant dictates the rules of the game, so if the recording feature is critical and the current version of the software does not support it natively, it is worth considering alternative options, which will be discussed below.
Activation of recording in the standard Google Phone application
If your Redmi 9C has a blue Google phone icon, the process of turning on the record has its own peculiarities: Google requires you to notify the person when recording begins, and it is almost impossible to bypass this with regular means, but the feature itself should be available in the settings.
Open the Phone app and click on the three dots in the top right corner of the screen. In the drop-down menu, select Settings. Next, look for Call Record. If there is no such section, the function is blocked for your region or account, and you will need to use the methods described in the following sections.
Inside the call logging menu, you need to activate the Auto Record switch, and you can configure filters here, which is to record all calls that are coming only from numbers that are not saved in contacts or from specific people, and it's a very flexible tool for those who need control over incoming information.
- 📞 Automatically record all incoming and outgoing calls without user input.
- 🔇 Loud warning of the interlocutor about the beginning of the recording (“This call is recorded...”) through the speaker.
- 💾 Save files to a separate folder inside the Phone app, not in a shared voice recorder.
- 🗑️ Automatically delete old records when memory is scarce (configurable parameter).
It is worth noting that in some regions (for example, India or Thailand), the interlocutor warning may not be available, but for users from the CIS and Europe, it is a mandatory requirement of the legislation that Google implements, and the recording quality is usually high, since it uses direct digital stream, rather than recording from a microphone.
⚠️ Note: If the Google Phone settings do not include Call Record, do not attempt to install modified calls. APK-Files from unverified sources – this can disrupt the entire security system of the smartphone.
Using the MIUI Dialer app for hidden recording
For those users who are not satisfied with voice alert recording, there is an alternative in the form of installing a native MIUI dialer. This method requires deeper intervention in the system, but allows you to record unnoticed by the interlocutor, which is often a decisive factor.
The essence of the method is to replace the system application "Phone" with a version from Chinese firmware. 9C Based on the MediaTek processor, search for the right version APK-It can take a while. You need to look for versions that are labeled. MIUI Dialer compatible with your version of Android.
After installation APK-If you have a file and you have all the permissions you need (access to contacts, microphone, phone), you'll have a signature recording button in the call interface, and when you talk, it may be inactive before you start a conversation, but when you connect, it allows you to activate the fixation with a single click without sound signals.
Sequence of action:
1 Download APK MIUI Dialer (version for Global ROM).
Insert installation from unknown sources.
3. Install the application and open it.
4. Assign it to the default application for calls.
5 In the settings, enable "Autoset" and hide the recording icon.However, this method has its risks: Updating the system via OTA (over the air) can return the standard Google Dialer, and the procedure will have to be repeated.In addition, some banking applications may not work properly if the system components are changed, although this is rare on Xiaomi 9C.
Third-party applications for recording conversations
If system methods don’t meet your needs or cause problems, Google Play’s specialized apps come to the rescue.The market offers a lot of solutions, but due to the limitations of Android 10+, most of them have switched to recording sound through a microphone, which can reduce the quality when talking in a noisy room.
One of the most reliable solutions is the Cube ACR application. It can bypass many system restrictions using special accessibility services (Accessibility Service), after installation, you must give the application all the permissions requested, including the right to overlay over other windows and access to the phone.
Another popular option is Appliqato's Automatic Call Recorder or TapeACall, which often have paid subscriptions for advanced functionality, but the basic recording is available in free versions, and allows you to sync recordings to the cloud, which is convenient for saving a history in case of loss of the phone.
- 📱 Cube ACR: Support for VoIP calls (Viber, WhatsApp, Telegram) on some models.
- ☁️ Cloud Storage: Automatically upload records to Google Drive or Dropbox.
- 🎙️ Customize the microphone sensitivity to improve recording quality in silence.
- 🔒 Password protection of access to the list of recorded conversations within the application.
It's important to understand that when using third-party apps, recording often goes through the speaker and microphone at the same time, which means that if you put your phone to your ear while you're talking, the speakers may overlap and the recording will be deaf.
💡
To improve recording quality with third-party applications, turn off noise cancellation in the audio settings if such an option is available in your version of MIUI.
Configure the quality parameters and file format
The quality of stored audio files directly affects their legibility, especially when it comes to important contract details or account numbers. In standard settings, Xiaomi 9C often has a compressed format that saves space but loses the frequencies of the human voice.
The voice recorder app or call recording settings (if available) should look for bitrate and format options. The optimal choice is MP3 or M4A with a bitrate of at least 128 kbit/s. The WAV format provides the best quality, but the files take up 5-10 times more space, which can be a problem for the Redmi 9C with its modest storage capacity.
You also need to pay attention to the way you save files. By default, records can lie deep in system folders, like Internal. Storage/MIUI/sound_recorder/call_rec or Phone/Recordings. It is better to immediately configure the folder with records with the cloud service or regularly transfer them to your computer.
| Parameter | Recommended value | Impact on the system |
|---|---|---|
| Format | MP3 / M4A | Balance of quality and size |
| Bitreit | 128 - 192 kbit/s | Clear voice |
| Sound source | Microphone / Voice Call | Depends on the app. |
| Storage | SD-card (if any) | Saving Internal Memory |
Remember to check the free space on your device periodically. Long conversations in high quality can quickly exhaust the available space, which will lead to a recording stop or slow down the smartphone as a whole.
☑️ Checking the quality settings
Solution and lack of sound in the recording
One of the most common problems with Xiaomi 9C users is when a recording is created, but when playing, you hear only the silence or voice of the interlocutor, and your voice is missing.
Most often, the reason is that the system blocks access to the internal audio channel for third-party applications, and then it helps to turn on the speaker while you're talking, the sound starts to go through the speaker, the microphone picks it up, and the recording becomes two-way, and it's a crutchy, but working solution.
Also, the problem may be permissions. Go to Settings → Apps → All apps → (Your recording app) → Permissions. Make sure you allow microphone use and, if any, phone access. Sometimes you need to allow display over other windows.
Why is the recording interrupted?
If you use a Bluetooth headset, the recording quality can drop dramatically or the sound can go completely off, and this is due to the audio profile, in which case the system can switch to recording from a phone microphone that is far from the sound source, or vice versa, try to write from the headset, but have no rights to do so.
⚠️ Note: When using Bluetooth headsets for important recording conversations, always make a test call to a friend to check if the audio file is saved correctly.
Legal aspects and ethics of recording conversations
Before you record all your conversations, you should remember the law. In different countries, the laws regarding recording telephone conversations differ. In the Russian Federation, according to the Federal Law on Operational Investigation Activities and the Civil Code, recording your own conversation for personal purposes is usually allowed if you are a participant in the conversation.
However, posting or sharing a record without the consent of the person involved is already a violation of the right to privacy, so when using Redmi 9C to record dialogs, keep in mind the confidentiality of data.
If the recording is made to prove fraud or threats, it can be used as evidence in court, but only if the procedure for obtaining this data is followed. In the corporate sector, recording employee conversations with customers requires a mandatory warning (“Conversation is recorded”), ignoring which leads to fines.
- ⚖️ Recording for the personal needs of the participant in the conversation is usually legal.
- 🚫 Publication of the record without the consent of the second person may be illegal.
- 🏢 Business sector must warn customers about recording.
- 🔐 Storing records with personal data requires protection against leaks.
The use of technology must be conscious. The call recording feature on Xiaomi is a powerful tool that, when used correctly, increases your security and helps you store important information, but requires accountability.
